2 Washing principle
Pass the force through the triangle to
the pulley
The belt wheel drives the drive shaft movement
The drive shaft drives the planetary gear assembly through the spline and decelerates
The planetary gear assembly drives the wash shaft rotation through the spline The wash shaft drives the wheel to complete the washing action
Principle of washing deceleration
bull Planetary gear part is a typical gear transmission system in engineering epicyclic train figure in the gear wheel gear 1 and 3 are referred to as the center (also called the sun wheel) including 1 gear shaft gear is a gear ring 3 it and clutch shaft brake disc dehydration shaft circumferential fixed connection
Electric machine

]transmission shaft
Clutch set
Shaft assembly
Ratchet embrace spring Take off the bucket
3 Principle of dehydration
The belt wheel drives the drive shaft movement
After opening the fork the ratchet is tightly closed with the clutch and when the drive shaft drives the clutch shaft it will hold the spring and clutch it
Hold the other end of the spring and the clutch shaft to die drive it to rotate together
The motion of the clutch shaft is the motion of the shaft assembly and the dehydration axis leads to the dehydration of the bucket
Pass the force through the triangle to the pulley
Condition the tractor unlocks the drain valve and the dipper
Wash and dehydrate
bull Condition when the ratchet and ratchet are out of gear the motor is turning and the clutch shaft is driven by the clutch shaft which forms the dehydration of the washing machine
bull Ratchet in the process of response in A PM with ratchet gearing when ratchet back
to the original point ratchet is ratchet drive A distance which drives the ratchet embrace spring move between Δ embrace spring and form A certain space between the clutch set can make the clutch set free rotation in the embrace spring
bull Brake washing machine dehydration loosen ratchet spring looping drive shaft through a clutch cover ratchet embrace spring clutch shaft weeks to fixed in the forward direction drive shaft clutch shaft (including brake disc and shaft) dehydration and shaft can be viewed as a whole planetary gear transmission effect no longer turn motors to drive shaft assembly as a whole through the triangle belt transmission so as to realize function of dehydration (pulsator take off the bucket synchronous clockwise)
4 The principle of braking
dehydration The tractor is reset brake
When dehydrating the tractor will open the pole open the fork at the same time and the shaft assembly is in free state At this time the bucket will be dehydrated
clockwise
In the process of dehydration when the power supply is cut off the bucket or door cover is opened the tractor will reset quickly and the dialing lever and fork will be retaken quickly
After the fork is reset the ratchet spring is in the initial condition of the washing the brake belt holds the brake disc when the lever is reset prevents the shaft assembly from continuing and the dehydration action stops
bull The debucket brake is divided into positive and backward brakingReverse braking requires sufficient braking torque to fully limit the reverse rotation of the removal of the bucketThe forward braking doesnt have to completely limit the forward rotation of the bucket However it is not impossible to limit the rotation speed of the wave rotation which affects the washing ratio The second effect of forward braking is that when the dehydration ends or the door lid is opened in the process of dehydration the removal of the bucket can be quickly stopped and the brake torque must be properly implemented The braking torque cant be too large if too large the bucket stops too fast The braking torque should not be too small too small to take off the bucket and stop too slow the braking time will exceed the standard
The implementation of forward braking
bull The forward braking of the bucket is brought by the brakeWhen the dehydration ends and the brake or the washing occurs the dial is in the position shown in the black line and the brake band and the brake disc hold together to produce the friction force under the action of the torsion spring The torque of the torsion spring is large resulting in greater frictionWhen the reverse rotation is not fixed the brake band of this type of installation is very poor When the rod is in the position of the line at the time of dehydration the brake band and the brake disc are separated and the bucket can be turned (dehydration)
5 The implementation of reverse braking
bull The inner structure of a single bearing is realized by a single bearing and the bearing of the shaft assembly is supported by ordinary ball bearings There are also one-way partsA single bearing is a kind of bearing that can rotate freely in one direction and lock in another One-way bearing metal shell contains a number of roller needle or ball and the rolling block shape so that it can only scroll in one direction while in another direction will produce very big resistance (the so-called one-way)

6 Sealing principle
Small oil seal
The small oil seal is pressed into
the dewatering shaft to prevent
grease leakage in the shaft
assembly It also prevents water
leakage into the shaft assembly at
one end of the washing shaft
Big oil seal
The large oil seal is pressed into
the cover plate to prevent the
water seeping into the inside of the
clutch
bull Sealed by big oil seal and oil seal oil seal between dehydration and fill the bucket sealing small oil seal to realize washing shaft and dehydration the seal between the big oil seal has two sealing lip so also called double seal only a small oil seal sealing lip say again so single seal
7 Working principle of dust proof and supporting part
bull The main effect of the dustproof ring is to prevent the dirt from falling on the brake disc to affect the brake torque
bull The working principle of the supporting part is simple so we wont talk about it
Common failures and maintenance 三
1 During the wash the barrel and the turn
A The barrel clockwise and rotation during washing
Cause analysis The maintenance method
The bar is connected with the tractor and the brake band is not fully holding the brake discAfter a certain period of operation of the clutch the brake belt wear out and friction decreasesThere is grease on the brake disc
Adjust the position of the connecting plate and the dialThe brake belt should be replaced Analyze the source of oil pollution If the brake disc itself is dirty replace the brake band and clean the brake disc If the shaft assembly oil leak the brake disc and clutch shaft are cracked or damaged and the clutch needs to be replaced

B The barrel counterclockwise and rotation during washing
Cause analysis
The maintenance method
Change of clutch
A sliding phenomenon occurs between the one - way bearing and the dehydration shaft2 The sliding phenomenon occurs between the single bearing and the shellThe one-way bearing is bad
2 The washing wheel is one-wayreversed
Cause analysis The maintenance method
When washing the ratchet
component does not open a
certain amount of residual so
that the clutch sleeve can not
rotate freely in a ratchetThe
inner hole of the ratchet
shrinks The one-way bearing is
skidded in the shell
Check whether the fork
components are deformed in the
initial condition of the washing
and if they have been deformed
replace the fork components If
it is not deformed it will
shrink the inside of the ratchet
and replace the ratchetIf for
the reason during the washing
there will be accompanied with
the phenomenon of rotation
The normal state
Failure state
Click reset
Incomplete reset
Fork normal

Smoothly into the
Sticking clutch set
3 Dehydrated action
Cause analysis maintenance methods
bull The gap between the pole and the connecting plate of the tractor is too large and the pawl is not fully detached from the ratchet bull The gap between the adjusting screw and the dial rod is too large which causes the brake belt and the forked fork to not be fully opened bull A ratchet ruptured bull For other reasons the bearing is damaged due to the leakage the brake belt is rusty and the brake
disc is killed
bull Adjust the pull rod and the connecting plate to the proper position bull Adjust the adjustment screw to between 0~ 02mm bull Replace the ratchet ring spring assembly
bull Replacement clutch
The normal state
Failure state
Suitable spacing Suitable clearance 0 ~ 02mm
Spacing is larger Spacing is larger
4 Washing no action
Cause analysis maintenance methods
bull If the pulley is turned by hand if it cannot be turned it is the corrosion card death of the planetary gear or the rust of the oil copper lining and the shaft bull The clutch can function normally and check whether the wheel is wearing bull The tri-band wear and tear fracture bull Motor failure
bull Replace the clutch
bull Change of wheel
bull Replace the triangle
bull Change motor

5 No dehydration
Cause analysis maintenance methods
bull The v-belt fails Bearing rust The ratchet cannot be opened the pulley square hole is damaged the lock nut is loose bull The ratchet is slipping and sliding bull The brake disc and brake disc are held to death bull I have an electrical fault
Change the triangle
Replace the clutch Corresponding maintenance
The outer diameter of the casing is small or
the inner diameter of a ratchet is large enough to
replace the clutch or spring Or the entrant is
impurities Replace the ratchet assembly
In the case of drainage whether the bucket
can be turned by rotating clockwise Yes the brake
disc is not cleaned One way bearing reverse
Look for electrical reasons
6 Leaking water (excluding water buckets)
Cause analysis maintenance methods
Large oil seal lip wear and tear long time leakage can lead to clutch bearing brake disc and other parts rust the clutch can not be normal dehydration
The abrasion of the oil seal lip is broken and the water seeps into the clutch shaft assembly causing the planetary gear the shaft lining and other rust the clutch cannot be washed normally
Remove the leakage factors of the parts such as buckets and drains and make sure to replace the clutch after the clutch is leaking
7 Running different sound
Cause analysis maintenance methods
A Washing different sound
The involute tooth profile of the planetary gear and gear ring is not completely consistent or the amount of oil in the gears is too small and the sound of purr will be issued during operation
The axis of the washing shaft and the transmission axis are not in a straight line resulting in uneven bearing force and a long time of wear and loss of the axle At this point turning the pulley with your hand will have a noticeable rotation (late)
The wheel has been worn and loos
First remove the wave wheel to eliminate the sound of the wave the second rule of the motor
Replace the clutch To replace the wheel
B Dehydrating noise (removal of derrick bucket etc)
Cause analysis maintenance methods
bull When the clearance of
the composite bearing is not
uniform the bearing will be
sent out during operation
When you turn it manually
there is a sense of car lag
bull Copper lining wear use
your hand to hold the pulley
and feel the radial pulse
bull Troubleshoot other
problems such as lifting rod
bucket and motor etc
bull The bearing rings and the
clutch is replaced
bull Replace the clutch

The belt wheel drives the drive shaft movement
The drive shaft drives the planetary gear assembly through the spline and decelerates
The planetary gear assembly drives the wash shaft rotation through the spline The wash shaft drives the wheel to complete the washing action
Principle of washing deceleration

3 Principle of dehydration
The belt wheel drives the drive shaft movement
After opening the fork the ratchet is tightly closed with the clutch and when the drive shaft drives the clutch shaft it will hold the spring and clutch it
Hold the other end of the spring and the clutch shaft to die drive it to rotate together
The motion of the clutch shaft is the motion of the shaft assembly and the dehydration axis leads to the dehydration of the bucket
Pass the force through the triangle to the pulley
Condition the tractor unlocks the drain valve and the dipper
Wash and dehydrate
bull Condition when the ratchet and ratchet are out of gear the motor is turning and the clutch shaft is driven by the clutch shaft which forms the dehydration of the washing machine
bull Ratchet in the process of response in A PM with ratchet gearing when ratchet back
to the original point ratchet is ratchet drive A distance which drives the ratchet embrace spring move between Δ embrace spring and form A certain space between the clutch set can make the clutch set free rotation in the embrace spring
bull Brake washing machine dehydration loosen ratchet spring looping drive shaft through a clutch cover ratchet embrace spring clutch shaft weeks to fixed in the forward direction drive shaft clutch shaft (including brake disc and shaft) dehydration and shaft can be viewed as a whole planetary gear transmission effect no longer turn motors to drive shaft assembly as a whole through the triangle belt transmission so as to realize function of dehydration (pulsator take off the bucket synchronous clockwise)
4 The principle of braking
dehydration The tractor is reset brake
When dehydrating the tractor will open the pole open the fork at the same time and the shaft assembly is in free state At this time the bucket will be dehydrated
clockwise
In the process of dehydration when the power supply is cut off the bucket or door cover is opened the tractor will reset quickly and the dialing lever and fork will be retaken quickly
After the fork is reset the ratchet spring is in the initial condition of the washing the brake belt holds the brake disc when the lever is reset prevents the shaft assembly from continuing and the dehydration action stops
bull The debucket brake is divided into positive and backward brakingReverse braking requires sufficient braking torque to fully limit the reverse rotation of the removal of the bucketThe forward braking doesnt have to completely limit the forward rotation of the bucket However it is not impossible to limit the rotation speed of the wave rotation which affects the washing ratio The second effect of forward braking is that when the dehydration ends or the door lid is opened in the process of dehydration the removal of the bucket can be quickly stopped and the brake torque must be properly implemented The braking torque cant be too large if too large the bucket stops too fast The braking torque should not be too small too small to take off the bucket and stop too slow the braking time will exceed the standard
The implementation of forward braking
bull The forward braking of the bucket is brought by the brakeWhen the dehydration ends and the brake or the washing occurs the dial is in the position shown in the black line and the brake band and the brake disc hold together to produce the friction force under the action of the torsion spring The torque of the torsion spring is large resulting in greater frictionWhen the reverse rotation is not fixed the brake band of this type of installation is very poor When the rod is in the position of the line at the time of dehydration the brake band and the brake disc are separated and the bucket can be turned (dehydration)
5 The implementation of reverse braking
bull The inner structure of a single bearing is realized by a single bearing and the bearing of the shaft assembly is supported by ordinary ball bearings There are also one-way partsA single bearing is a kind of bearing that can rotate freely in one direction and lock in another One-way bearing metal shell contains a number of roller needle or ball and the rolling block shape so that it can only scroll in one direction while in another direction will produce very big resistance (the so-called one-way)

The small oil seal is pressed into
the dewatering shaft to prevent
grease leakage in the shaft
assembly It also prevents water
leakage into the shaft assembly at

Big oil seal
The large oil seal is pressed into
the cover plate to prevent the
water seeping into the inside of the
clutch
bull Sealed by big oil seal and oil seal oil seal between dehydration and fill the bucket sealing small oil seal to realize washing shaft and dehydration the seal between the big oil seal has two sealing lip so also called double seal only a small oil seal sealing lip say again so single seal
7 Working principle of dust proof and supporting part
bull The main effect of the dustproof ring is to prevent the dirt from falling on the brake disc to affect the brake torque
bull The working principle of the supporting part is simple so we wont talk about it

In the process of dehydration when the power supply is cut off the bucket or door cover is opened the tractor will reset quickly and the dialing lever and fork will be retaken quickly
After the fork is reset the ratchet spring is in the initial condition of the washing the brake belt holds the brake disc when the lever is reset prevents the shaft assembly from continuing and the dehydration action stops
bull The debucket brake is divided into positive and backward brakingReverse braking requires sufficient braking torque to fully limit the reverse rotation of the removal of the bucketThe forward braking doesnt have to completely limit the forward rotation of the bucket However it is not impossible to limit the rotation speed of the wave rotation which affects the washing ratio The second effect of forward braking is that when the dehydration ends or the door lid is opened in the process of dehydration the removal of the bucket can be quickly stopped and the brake torque must be properly implemented The braking torque cant be too large if too large the bucket stops too fast The braking torque should not be too small too small to take off the bucket and stop too slow the braking time will exceed the standard
The implementation of forward braking
bull The forward braking of the bucket is brought by the brakeWhen the dehydration ends and the brake or the washing occurs the dial is in the position shown in the black line and the brake band and the brake disc hold together to produce the friction force under the action of the torsion spring The torque of the torsion spring is large resulting in greater frictionWhen the reverse rotation is not fixed the brake band of this type of installation is very poor When the rod is in the position of the line at the time of dehydration the brake band and the brake disc are separated and the bucket can be turned (dehydration)
5 The implementation of reverse braking
bull The inner structure of a single bearing is realized by a single bearing and the bearing of the shaft assembly is supported by ordinary ball bearings There are also one-way partsA single bearing is a kind of bearing that can rotate freely in one direction and lock in another One-way bearing metal shell contains a number of roller needle or ball and the rolling block shape so that it can only scroll in one direction while in another direction will produce very big resistance (the so-called one-way)

bull The forward braking of the bucket is brought by the brakeWhen the dehydration ends and the brake or the washing occurs the dial is in the position shown in the black line and the brake band and the brake disc hold together to produce the friction force under the action of the torsion spring The torque of the torsion spring is large resulting in greater frictionWhen the reverse rotation is not fixed the brake band of this type of installation is very poor When the rod is in the position of the line at the time of dehydration the brake band and the brake disc are separated and the bucket can be turned (dehydration)
5 The implementation of reverse braking
bull The inner structure of a single bearing is realized by a single bearing and the bearing of the shaft assembly is supported by ordinary ball bearings There are also one-way partsA single bearing is a kind of bearing that can rotate freely in one direction and lock in another One-way bearing metal shell contains a number of roller needle or ball and the rolling block shape so that it can only scroll in one direction while in another direction will produce very big resistance (the so-called one-way)

6 Leaking water (excluding water buckets)
Cause analysis maintenance methods
Large oil seal lip wear and tear long time leakage can lead to clutch bearing brake disc and other parts rust the clutch can not be normal dehydration
The abrasion of the oil seal lip is broken and the water seeps into the clutch shaft assembly causing the planetary gear the shaft lining and other rust the clutch cannot be washed normally
Remove the leakage factors of the parts such as buckets and drains and make sure to replace the clutch after the clutch is leaking
7 Running different sound
Cause analysis maintenance methods
A Washing different sound
The involute tooth profile of the planetary gear and gear ring is not completely consistent or the amount of oil in the gears is too small and the sound of purr will be issued during operation
The axis of the washing shaft and the transmission axis are not in a straight line resulting in uneven bearing force and a long time of wear and loss of the axle At this point turning the pulley with your hand will have a noticeable rotation (late)
The wheel has been worn and loos
First remove the wave wheel to eliminate the sound of the wave the second rule of the motor

3 Principle of dehydration
The belt wheel drives the drive shaft movement
After opening the fork the ratchet is tightly closed with the clutch and when the drive shaft drives the clutch shaft it will hold the spring and clutch it
Hold the other end of the spring and the clutch shaft to die drive it to rotate together
The motion of the clutch shaft is the motion of the shaft assembly and the dehydration axis leads to the dehydration of the bucket
Pass the force through the triangle to the pulley
Condition the tractor unlocks the drain valve and the dipper
Wash and dehydrate
bull Condition when the ratchet and ratchet are out of gear the motor is turning and the clutch shaft is driven by the clutch shaft which forms the dehydration of the washing machine
bull Ratchet in the process of response in A PM with ratchet gearing when ratchet back
to the original point ratchet is ratchet drive A distance which drives the ratchet embrace spring move between Δ embrace spring and form A certain space between the clutch set can make the clutch set free rotation in the embrace spring
bull Brake washing machine dehydration loosen ratchet spring looping drive shaft through a clutch cover ratchet embrace spring clutch shaft weeks to fixed in the forward direction drive shaft clutch shaft (including brake disc and shaft) dehydration and shaft can be viewed as a whole planetary gear transmission effect no longer turn motors to drive shaft assembly as a whole through the triangle belt transmission so as to realize function of dehydration (pulsator take off the bucket synchronous clockwise)
4 The principle of braking
dehydration The tractor is reset brake
When dehydrating the tractor will open the pole open the fork at the same time and the shaft assembly is in free state At this time the bucket will be dehydrated
clockwise
In the process of dehydration when the power supply is cut off the bucket or door cover is opened the tractor will reset quickly and the dialing lever and fork will be retaken quickly
After the fork is reset the ratchet spring is in the initial condition of the washing the brake belt holds the brake disc when the lever is reset prevents the shaft assembly from continuing and the dehydration action stops
bull The debucket brake is divided into positive and backward brakingReverse braking requires sufficient braking torque to fully limit the reverse rotation of the removal of the bucketThe forward braking doesnt have to completely limit the forward rotation of the bucket However it is not impossible to limit the rotation speed of the wave rotation which affects the washing ratio The second effect of forward braking is that when the dehydration ends or the door lid is opened in the process of dehydration the removal of the bucket can be quickly stopped and the brake torque must be properly implemented The braking torque cant be too large if too large the bucket stops too fast The braking torque should not be too small too small to take off the bucket and stop too slow the braking time will exceed the standard

Remove the leakage factors of the parts such as buckets and drains and make sure to replace the clutch after the clutch is leaking
7 Running different sound
Cause analysis maintenance methods
A Washing different sound
The involute tooth profile of the planetary gear and gear ring is not completely consistent or the amount of oil in the gears is too small and the sound of purr will be issued during operation
The axis of the washing shaft and the transmission axis are not in a straight line resulting in uneven bearing force and a long time of wear and loss of the axle At this point turning the pulley with your hand will have a noticeable rotation (late)
The wheel has been worn and loos
First remove the wave wheel to eliminate the sound of the wave the second rule of the motor
Replace the clutch To replace the wheel

4 The principle of braking
dehydration The tractor is reset brake
When dehydrating the tractor will open the pole open the fork at the same time and the shaft assembly is in free state At this time the bucket will be dehydrated
clockwise
In the process of dehydration when the power supply is cut off the bucket or door cover is opened the tractor will reset quickly and the dialing lever and fork will be retaken quickly
After the fork is reset the ratchet spring is in the initial condition of the washing the brake belt holds the brake disc when the lever is reset prevents the shaft assembly from continuing and the dehydration action stops
bull The debucket brake is divided into positive and backward brakingReverse braking requires sufficient braking torque to fully limit the reverse rotation of the removal of the bucketThe forward braking doesnt have to completely limit the forward rotation of the bucket However it is not impossible to limit the rotation speed of the wave rotation which affects the washing ratio The second effect of forward braking is that when the dehydration ends or the door lid is opened in the process of dehydration the removal of the bucket can be quickly stopped and the brake torque must be properly implemented The braking torque cant be too large if too large the bucket stops too fast The braking torque should not be too small too small to take off the bucket and stop too slow the braking time will exceed the standard
The implementation of forward braking
bull The forward braking of the bucket is brought by the brakeWhen the dehydration ends and the brake or the washing occurs the dial is in the position shown in the black line and the brake band and the brake disc hold together to produce the friction force under the action of the torsion spring The torque of the torsion spring is large resulting in greater frictionWhen the reverse rotation is not fixed the brake band of this type of installation is very poor When the rod is in the position of the line at the time of dehydration the brake band and the brake disc are separated and the bucket can be turned (dehydration)
5 The implementation of reverse braking
bull The inner structure of a single bearing is realized by a single bearing and the bearing of the shaft assembly is supported by ordinary ball bearings There are also one-way partsA single bearing is a kind of bearing that can rotate freely in one direction and lock in another One-way bearing metal shell contains a number of roller needle or ball and the rolling block shape so that it can only scroll in one direction while in another direction will produce very big resistance (the so-called one-way)

5 The implementation of reverse braking
bull The inner structure of a single bearing is realized by a single bearing and the bearing of the shaft assembly is supported by ordinary ball bearings There are also one-way partsA single bearing is a kind of bearing that can rotate freely in one direction and lock in another One-way bearing metal shell contains a number of roller needle or ball and the rolling block shape so that it can only scroll in one direction while in another direction will produce very big resistance (the so-called one-way)

bull The v-belt fails Bearing rust The ratchet cannot be opened the pulley square hole is damaged the lock nut is loose bull The ratchet is slipping and sliding bull The brake disc and brake disc are held to death bull I have an electrical fault
Change the triangle
Replace the clutch Corresponding maintenance
The outer diameter of the casing is small or
the inner diameter of a ratchet is large enough to
replace the clutch or spring Or the entrant is
impurities Replace the ratchet assembly
In the case of drainage whether the bucket
can be turned by rotating clockwise Yes the brake
disc is not cleaned One way bearing reverse
Look for electrical reasons
6 Leaking water (excluding water buckets)
Cause analysis maintenance methods
Large oil seal lip wear and tear long time leakage can lead to clutch bearing brake disc and other parts rust the clutch can not be normal dehydration
The abrasion of the oil seal lip is broken and the water seeps into the clutch shaft assembly causing the planetary gear the shaft lining and other rust the clutch cannot be washed normally
Remove the leakage factors of the parts such as buckets and drains and make sure to replace the clutch after the clutch is leaking
7 Running different sound
Cause analysis maintenance methods
A Washing different sound
The involute tooth profile of the planetary gear and gear ring is not completely consistent or the amount of oil in the gears is too small and the sound of purr will be issued during operation
The axis of the washing shaft and the transmission axis are not in a straight line resulting in uneven bearing force and a long time of wear and loss of the axle At this point turning the pulley with your hand will have a noticeable rotation (late)
The wheel has been worn and loos
First remove the wave wheel to eliminate the sound of the wave the second rule of the motor
Replace the clutch To replace the wheel
B Dehydrating noise (removal of derrick bucket etc)
Cause analysis maintenance methods
bull When the clearance of
the composite bearing is not
uniform the bearing will be
sent out during operation
When you turn it manually
there is a sense of car lag
bull Copper lining wear use
your hand to hold the pulley
and feel the radial pulse
bull Troubleshoot other
problems such as lifting rod
bucket and motor etc
bull The bearing rings and the
clutch is replaced
bull Replace the clutch
