OPERATING MANUAL 2. PRODUCT DESCRIPTION


2.2 Functional description

The TW 160 machine consists of a worm gear (gear drive) with flange-connected motor. Power transmission takes place on motors of the B9 model series (flanged-on design with 1 bearing) via a rigid connection between the motor and worm shaft via worm wheel, traction sheave shaft to the traction sheave. In the case of motors of the B5 model series (flanged-on design with 2 bearings), a flexible coupling (SA14) is required between the motor and gear drive.

Brake: The dual-circuit outside brake shoe is spring actuated. Two independently acting brake blocks press the brake lining with preset spring force onto the brake disc. The braking force is configured in such a way that one of the brake blocks is sufficient to bring an elevator car loaded with full weight to a standstill. The brake is released by electrically operated magnetic clamps. For manual operation, a brake release lever is fitted.

Setting up To isolate the body, the machine base frame is placed on isolation elements. These differ according to the type of mounting: a) Rubber block 100 x 100 x 50 high without base For mounting the machine on the machine room floor without a cement floor or directly surface mounted on the cement floor. b) Rubber block same as a) however with an additional base 140 x 140 x 80 mm high

For mounting on a cement floor, support cast in the cement floor. (floor covering thickness ≤ 60 mm)

Note: for the layout of the isolation, the load per isolation element should be 7 kN ÷ 12 kN.

15



Mounting the base frame Loosely bolt together base frames supplied as single parts in the machine room. Make sure that the supports are mounted with additional drilled holes (2 holes) and pulley support on the correct side. Mount and secure the deflecting pulley with axle on the pulley supports. Place and align the base frame on the isolation elements according to the plan of installation. Use lifting gear to place the machine on the base frame; the traction sheave must be on the deflecting pulley side. Move the machine sideways on the base frame until the required ASL dimension (parallel gap between the ropes at the rope departure) is reached. (Dimension "L" specifies the distance between the outer edge of the base frame and the securing holes for the machine.) Bolt the machine onto the base frame. Align the traction sheave and deflecting pulley as parallel. Balance out uneven surfaces by inserting the enclosed shims. The machine housing must not be tensioned. Tighten the screws with the prescribed torque. See chapter 9.1. Plumb the rope departure on the rope pulley at the elevator car and/or mounting on the car and counterweight. Explanation of abbreviated designations:

ASL = parallel gap between the ropes on the rope departure ∅DT = diameter of traction sheave ∅SR = diameter of deflecting pulley L = distance from the outer edge of the base frame to the mounting hole for

the machine on the machine base frame. Note: The specified direction for left-hand or right-hand design of the machine is defined by the arrangement of the traction sheave, viewed from the motor onto the machine (arrangement of the traction sheave on the right-hand side corresponds to right-hand design).

OPERATING MANUAL 5. MOUNTING THE MACHINE


5.1 Machine setup

Depending on the scope of the order, the gear drive is delivered mounted on the machine base frame. The base frame is set up depending on the customer on supports, beams, a concrete pedestal or directly cast in the machine room floor. In order to better comply with regulations for noise abatement and/or sound transmission, isolation elements are to be inserted between the frame supports and the ground. The number of rubber elements is based on the total weight load. The required individual load should be between 7000 and 12 000 N / per element. The location and arrangement of the rubber elements can be found in the plan of installation. Note: On arrangement of the supports, it is to be taken into account that the overall centre of gravity lies within the rubber elements (also in the case of elevator car suspension on the deflecting pulley side). If the supporting surface of the machine base frame is cast as a cement floor, the floor thickness should be ≤ 60 mm. Isolation elements with supports (80 mm high) are to be inserted. Part of the base is also to be cast in the floor. Mounting with inclined pulling or rope departure upwards (SA1) For the machine and base frame mount, the forces that arise in the pulling direction are also to be taken into account. Aligning the machine The machine is to be set up according to the plan of installation. The rope departure from the traction sheave is to be aligned plumb to the elevator car mounting or the elevator car rope pulley and the counterweight according to the drawing. With load applied to the ropes, the machine should be aligned horizontally on its support. Irregularities are to be balanced out by inserting shims under the floor support.

SA4, SA9 gear drive with extended worm wheel shaft and outside bearing

NB: On setting up a gear drive with outside bearing, it must be ensured without fail that

• the pedestal supports are mounted and secured according to instructions • the worm wheel shaft is aligned horizontally • the gear shaft bearings of the machine and the outside bearing are

exactly aligned

5.7 Mounting the rope guard for the traction sheave Use the enclosed screws to bolt the rope guard onto the rope guard carrier. Pivot the rope guard carrier to set the guard is such a way that the gap between the rope and guard on the rope run-in and run-out side of the traction sheave is as small as possible (1 - 2 mm). With inclined pulling, adapt the location of the rope guard carrier by remounting the changed rope pull direction. Note: Tighten the securing bolts of the rope guard carrier on the gear drive after alignment with the prescribed torque. Tightening torque, see table in the Appendix of the operating manual.

1 Rope guard carrier 2 Rope guard

NB: For machines with rope run-in direction of 0 - 90° above the horizontal (e.g.: machine arrangement up/down beside), an additional rope guard is required to prevent the entry of foreign bodies between the rope and groove. If the rope run-in zone is protected within the machine base frame, the function "protection against injury" is not required.

7.2 Lubrication

Lubricant Replacement interval Filling amount Synthetic gear oil SM1 For the first time after 3 years

then every 6 years 17 litres

Oil change • Before the oil change, run the gear until it reaches operating temperature. • Discharge the gear oil by removing the cap on the oil drain pipe. • Collect the old oil in a container specifically designed for the purpose. • Close the oil drain after discharging the gear with sealing tape and the cap. • Fill the machine with the prescribed amount of oil through the upper

opening on the gear box. • Check the level at the oil dip stick (see Fig. below). • Enter the date for the next oil change in the type plate on the oil inspection

hole cover, see chapter 3. • Never mix various types of oil. • Do not let any oil seep through to the groundwater. • Dispose of old oil as well as cleaning cloths contaminated with oil and

grease according to applicable regulations. • Only use lubricants approved by

THYSSENKRUPP AUFZUGSWERKE GmbH. Note: THYSSENKRUPP AUFZUGSWERKE GmbH shall not be liable for losses caused by the use of non-approved lubricants.

7.3 Checking the backlash

Wear enlarges the backlash on the worm drive between the worm wheel and worm shaft. If the wear limit value (backlash) of 2.5 mm is reached, the gear drive can no longer be deployed for safety reasons. The gear set (worm wheel and worm shaft) is to be replaced or the gear drive is to be replaced.

Measurement possibility: • Take the load off the gear drive; (remove ropes from the traction sheave) • Run the measuring operation with the brake closed • Fit a measuring attachment to the traction sheave; e.g. screw clamp • Specify the measured radius (M) and mark the measuring point (The radius (r) for the TW 160 = 186 mm) • Attach a dial gauge with magnet stator at the gear drive housing and align

to the measuring point (M). • Turn the traction sheave by hand until the dial gauge pointer moves. • Move the traction sheave back and forth until resistance is felt in both

directions. The tooth flanks of the worm wheel should have a load of approx. 20 - 50 N.

• Read off the dial gauge (ME). • Use the formula below to calculate the backlash. • This measurement is to be carried out in at least three different positions! M = radius ME = measurement result r = radius - worm wheel All dimensions in mm

Backlash = ME x r M

7.4 Replacing brake blocks

Note: With a remaining lining thickness of less than or equal to 3 mm, or if the linings are glazed, the brake linings must be replaced. • Before starting work, secure the counterweight and elevator car;

switch off the power to the installation. • Remove one brake block; mount the brake linkage and armature

base plates on new brake blocks. • Fit the pre-assembled brake block and align to the middle of the

brake disc. Ensure that the brake linkage is aligned. • Set the brake block stroke. The brake block stroke should be

0.3 mm + 0.1 mm, measured to the middle of the brake disc. • Pretension the springs by approx. 20.5 mm. • Modify, replace and set the second brake block in the same

manner. • After replacement, operate with electrical recall and observe

whether both brake blocks open evenly. • Check the stroke paths and, if required, adjust.

7.5 Setting braking deceleration

The brake adjustment is to be carried out only with one effective brake

block with the elevator car loaded with the rated load on a descending run (full down) or with an empty elevator car on an ascending run (empty up) according to the deceleration values in the table below.

The braking torque must be set on uniformly on both brake blocks by pretensioning the brake spring depending on the installation.

Table: brake deceleration values

Note: If brake test switch SA3 is present, this must be checked or

adjusted after brake adjusting. See SA3 fitting the brake monitoring switch, chapter 8

41



7.6 Setting the brake block stroke and armature base plate

Before first commissioning and of both during monitoring, the working stroke of the brake blocks, the pretension and movement of the armature base plates are to be checked. On opening the brakes, make sure that both brake blocks work with the same stroke. The working stroke of the brake block should be 0.3 mm + 0.1 mm, measured at the height of the middle of the brake block. In the event of deviations, it can be corrected by adjusting the armature screw, item 5. To set the working stroke, the lock nut of the armature screw must be loosened and the prescribed stroke of the brake block set by turning the screw. After a longer period of use, it can occur that the rubber disc settles between the armature base plate and brake block, and this means that the pretension of the armature base plate to insufficient. To restore the pretension, the lock nuts between the brake block and armature base plate must be adjusted. In doing so, lightly grease the rubbing surface between the head of the screw and the armature base plate. Correct pretension is achieved when the armature base plate can be turned on the armature screw despite light suction.

7.7 Traction sheave replacement

Disassembly:

• De-energise the system, secure car and counterweight. • Ease load on traction sheave; lay down ropes. • Undo the screws on the mounting plate for the traction sheave and

loosely screw them in the outer circle of holes of the traction sheave into the traction sheave hub.

• Place a spacer of approx. 5 – 10 mm thickness between the shaft end and the traction sheave.

• By tightening the screws diagonally and evenly, remove the traction sheave from the shaft.

NB: with SA9, the worm wheel shaft must be supported (self-aligning bearing!) before removing the outside bearing.

Installation:

• Clean shaft end and traction sheave bore. Under no circumstances, are

the dimensions of the feather key, groove, shaft or drilled hole to be changed.

• Do not apply grease or oil to the shaft and bore. • Place the new traction sheave on the conical shaft end of the worm

wheel shaft. • Align the locations of the feather key and groove in relation to one

another. • Push the traction sheave onto the worm wheel shaft. • Screw on a disc with new screws (microencapsulated) and detent

edged washers on the inner circle of holes of the disc. Tighten the screws evenly and alternately.

Danger: if mounted incorrectly, the traction sheave can come loose. • Ensure screws are secure and tightening torque is correct ! See table 9 in the Appendix.

43



7.8 Motor replacement

Disassembly: Place the new motor in position; check the technical data.

Disconnect the power from the installation and secure the car and counterweight. Attach and secure the motor to the lifting gear. Unplug the electrical connections and lines from the motor (motor and magnetic clamp connections). Remove the nuts from the brake and coupling disc. In the case of motors with design B5 SA14, follow the installation instructions for the flexible coupling in the Appendix. Remove the screws from the motor. Carefully pull the motor from the studs and place on the ground. Installation: Attach and secure the replacement motor to the lifting gear. Raise the motor using the lifting gear and align the motor coupling and brake disc. The locations of the securing holes must match those of the screws. Push the motor and coupling onto the screws on the gear drive and brake disc. Screw on the nuts and tighten evenly with the prescribed torque (see table with tightening torques in the Appendix).

Note: In the case of motors with design B5, follow the assembly instructions for the flexible coupling SA14.

44



7.9 Checking for escaping grease / oil Examine the area around the bearing cover, brake drum and brake linings for traces of oil. A small amount of escaping oil means individual drops of oil or traces of oil in the area of the bearing seal.

Contamination level Procedure No escaping oil determined Check regularly within the

framework of maintenance Every 3 months (6 months if elevator used infrequently, < 50 000 runs per year)

If a small amount of escaping oil is determined

Clean and check regularly within the framework of

maintenance

Every 3 months (6 months if elevator used infrequently, < 50 000 runs per year)

If a large amount of escaping oil is determined or oil is escaping from the brake disc / brake linings

Clean the drive and brake, if necessary, and carry out short-term repair. Before continuing operation, run a brake test until replacement. If the braking effect is inadequate, shut down the installation

Repair after 4 weeks at the latest

8.2 Brake monitoring circuit SA3

8.2.1 Version for THYSSEN TCM control systems The brake monitoring circuit checks the brake blocks. It prevents motor movements when the brake is partially or fully closed. It enables detection of any brake lining wear at an early stage. Switches (sensors) are used to check whether the brake blocks are closed, open, or worn. The travel signal is used for the evaluation. If the monitoring circuit triggers, it switches the drive off once the destination has been reached. The indicator is in the form of light emitting diode at the sensors. If a Teleservice device is connected, the fault is shown on the display.

Requirements for retrofitting:

Brake blocks with cast-on surfaces for mounting the setting screws. If these are not present, they must be replaced or a mechanical mounting must be created for mounting the screws.

Installation:

1. If not included in the scope of delivery, make two cables (0.3*0.75 mm² with PVC jacket) for direct connection of the sensors to the control system and connect them.

2. With the TW 160 gear drive, attach each of the sensors with a bracket to the drilled holes for the transport hanger. See Fig. 3

3. Screw lock nuts onto the enclosed hexagon screws and screw into the thread on the brake blocks. The switch tappet must be opposite the setting screw, but should not make contact with it.

Setting: Before making the sensor setting, the brake block stroke setting must be made! For description, see chapter 7

4. Switch on the emergency operation switch and elevator control system. 5. Adjust the setting screw for the switch until the LED lights up. 6. Slowly turn the screw back until the LED goes out. 7. Adjust the setting screw by ¼ revolution (corresponds to around 0.3 mm)

towards the switch and tighten the nut. LED lights up continuously. 8. Activate the motor to open and close the brakes, checking as you do so

that there is a switch change at the sensors between opened and closed brake.

48



8.2.2 Version for third-party products and older control systems (not TCI, not TCM)

The brake monitoring circuit BRC is a set of retrofit electronics for checking the brake blocks. It evaluates the signals of the sensors and forwards them to the downstream control electronics. When the value set at the sensor is reached, the device switches off the drive.

Indication is in the form of light emitting diodes at the sensors and at the BRC brake monitoring in the control cabinet. If a Teleservice device is connected, the fault is shown on the display.

9.2 Blocking clamp A blocking clamp that matches the traction sheave (rim width and design) is part of each machine

Deployment of the blocking clamp: Use the blocking clamp to prevent movements due to slipping ropes during installation work on the elevator car or counterweight or during work where the rope traction of the installation is insufficient (e.g. pulling out of the safety gear). Note: the blocking clamp is to be tensioned via the screwed connection until it is excluded that the slip will slip.

9.3 Manufacturer information, tachometer / pulse generator SA 7 General:

Installation

• Check the alignment of the tachodynamo and motor. • Use a well-machined and balanced coupling. Maintenance: • Every 2000 hours of operation. • Brushes • Check whether the brushes glide without obstruction in their housing. • Blow the dust from the brush carriers (do not use compressed air, as it might

contain oil particles). • Replace the brushes at a length of 5 to 6 mm. • The new brushes are preshaped to the contours of the collector. • However, exact surface contact is only reached after 10 hours of operation. • If a check means the brushes must be removed, select their position for later

installation at the original location. Collector • The layer that has formed under the brush path must not be removed. • In the event of contamination, clean using a cloth lightly dampened with

alcohol. • It is strictly prohibited to use abrasives. Lubrication • The dynamo is equipped with sealed bearings that have been given

permanent lubrication at the plant. No other lubrication is required. Important note We urgently advise you not to remove the rotor from the stator. Every removal leads to a change in the dynamo calibration.
