Duplex lead worms have slightly different leads and lead angles on the opposite face of the gear tooth. A range of backlash can be obtained by moving the worm axially. Worms have a high precision ground finish while worm wheels are made of abrasion-resistant Aluminum Bronze, making these the top-grade products. Worms come in bore type and shaft type styles.

Use of worm shafts eliminate the need to attach worms to shafts. Machining of bearing journal can be performed on the shafts. KWG2 or larger worm shafts have smaller pitch diameters than the comparable SWG worms, which allow more compact design with higher efficiency.

Superior strength and wear-resistance lead to compact designs with these gears. They have the same center distances as the more popular SW/CG series which permit substitution of these in place of SW/CG series for more demanding applications.

A large selection is available in these economical

and most popular series. Modules range from 0.8

to 6 and speed ratios from 1/10 to 1/120. Worm

wheels are also available in lightweight MC nylon

which can be used without lubrication.

■ Efficiency of SW, SUW/CG, BG, PG Worm Gear Pair (%)

The efficiency is approximately as follows, depending on the

assembly, loading, lubrication and rotational speed:

Single thread 40~50%

Double thread 50~60%

Self-locking is defined as the inability of worm wheels to drive the worms. Factors affecting the self-locking feature include the materials of the worm and worm wheel, lead angle, precision of manufacture, types of bearings, lubricant, etc. Thus, it is not dependent simply on the lead angle. But, in general, self-locking will occur when the lead angle in a single thread worm is less than 4。. For systems requiring fail-safe prevention of back drive, we

recommend other braking mechanisms or one-way clutches.

■ Precision Grades of Worm Wheels (KHK W 002) (Unit:μm)


3. Selecting Worms and Worm Wheels by Precision The precision standards of KHK stock worms and worm wheels are

established by us. The table below indicates the tolerance ranges for our products.

4. Other Points to Consider in the Selection Process

② Precision of worm wheels (KHK W 002)We have established standard grades 1~5 of worm wheels using JIS B 1702:1976, “Precision of Spur and Helical Gears” as the reference.

① Precision of worms (KHK W 001) KHK established the precision grades 1~4 of worms. For profile

and lead errors, JIS B 4354:1988, “Gear Hobs”, was used as reference. Lead errors are measured over one full revolution.

In order to use KHK stock worms and worm wheels safely, carefully read the Application Hints before proceeding. If there are questions or you require clarifications, please contact our technical department or your nearest distributor.

② To open up the bore to its maximum, calculate the bore size so that the tooth strength is weaker than the strength of the remaining material.

③ Some of SWG and KWG ground worms in small modules become hardened during heat treatment to the depth of 1 to 2mm below the root. Caution must be exercised when performing secondary operations on the bore.

④ Heat treating SW worms will increase lead and pressure angle errors. Therefore, pay special attention to the backlash and tooth contact.

⑤ PG plastic worm wheels are susceptible to effects of temperature and moisture. Dimensions may change between during remachining operations and afterwards.

① KHK stock worms and worm wheels are designed such that when assembled according to the specified mounting distance with a tolerance of H7~H8, the backlash shown in the product tables is obtained. Do not attempt to eliminate backlash by pushing worms into worm wheels or operate with the worm shifted in the direction along the tooth.

② Because of the helix of the gear teeth, worms and worm wheels produce axial thrust forces. The directions of thrust depend on the hand of the helix and the direction of rotation. This is illustrated below in Fig.2. The bearings must be selected properly to be able to handle these thrust forces.

If chucking operation using scroll chucks is

to be done, we recommend the use of new

or rebored jaws for improved precision.

Fig.1

Fig.2

① If you are reboring, it is important to pay special attention to locating the center in order to avoid runout. (Fig.1)

The reference datum for gear cutting or grinding is the bore. (For worm shafts, it is ground portion of the shaft.) Therefore,

use the bore or shaft for locating the center. If it is too difficult to do for small bores, the alternative is to use one spot on the bore and the runout of the side surface.

④ Because large thrust forces act on worms, if they are not secured to the shaft firmly, they tend to shift. Use of step shafts, set screws, dowel pins, etc., are recommended. Also, check for loosening of bearings due to thrust forces.

⑤ How well the worms and worm wheels are assembled has large effects on the friction of the unit. The tooth contact at the time of assembly must be checked for correctness as shown below.

① Before operating, check the following: ● Are the gears firmly mounted on the shafts? ● Have you eliminated uneven tooth contact?● Does the gear mesh have a proper amount of backlash? (Please avoid the condition of no backlash) ● Is there sufficient lubrication? ② If the gears are exposed, install a safety cover for protection.

Never touch gears while they are in motion. ③ Check the noise and vibration while the machine is in operation

for any unusual conditions. If an abnormality is encountered, recheck the gears and assembly conditions. Also, check lubrication after start-up. Sometimes, when the unit is initially being operated, lubricating oil deteriorates rapidly.

④ Worm gear drives generate more heat then other types of gear drives. Extra care should be exercised in the selection and amount of lubricant.

①KHK products are individually packaged to avoid damage. Depending on how they are handled, it is still possible to deform or break them. It is important to exercise care in handling these parts.

② Check the products as they are being taken out of the boxes. If any of them are rusted, scratched or dented, please return to the dealer where they were bought, for exchange.

③ KHK cannot guarantee the precision of gears once the customer performs a secondary operation on them.

● Verify that the worm axis is perpendicular to the worm

wheel axis.


3. Notes on Starting Operations

4. Other Points to Consider in Applications

● Check for the worm axis to be in the center of the worm

wheel face width.

● Confirm that the center of the worm wheel goes

through the midpoint of the worm length. The worm cannot rotate correctly if the worm is engaged close to either end of its length.

Example of KHK Gear Applications

298

The dual-lead worm is formed to give a difference between the right tooth surface and left tooth surface so that it provides a unique tooth profile in which the tooth thickness varies continuously, corresponding with the lead difference (Fig.1)The worm gear is also formed in its right and left tooth surface.When such a worm and worm gear are set up at a constant assembly distance and the worm is moved in the axial direction, the tooth thickness of the worm in mesh with the worm gear changes making backlash adjustment possible.An arrow marking on the outer circumference of the hub of the KHK duplex worm indicates the direction of assembly as well as acts as a guide for the backlash adjustment.When the worm is held with arrow mark pointing right, the tooth thickness is thinner on the right and thicker on the left. Therefore, moving the worm to the right causes the thicker teeth to come into actual engagement with the worm gear, thereby reducing the backlash (Fig.2)

The usual method of adjusting the backlash of a worm gear assembly is to modify the center distance. Once assembled, such adjustment require a major rework of the gearbox housing. The use of duplex worm gears allows the backlash adjustment to be made by axially shifting the worm. This simplifies greatly the assembly and maintenance operations. Because of the unique characteristics of the product, please take time to study its construction and proper use.

CAUTION: The amount of change in backlash ( △ j mm) in

relation to the axial movement of the duplex worm shaft

(V mm) can be calculated from the formula below.

CAUTION: The KHK duplex worm is designed so that, for all modules, the backlash reduces by 0.02mm when the worm is shifted 1mm.

KHK duplex worm gears differs in module between the right and left tooth surface and, therefore, you must orient the worm and worm wheel properly. Please carefully verify the following two aspects before proceeding with assembly.

An arrow indicating the orientation of assembly is stamped on both the duplex worm and worm wheel. When assembling the worm and worm wheel, check the worm wheel of the arrow mark on the front such that the direction of arrow mark on the worm coincides with that on the worm wheel. Should the assembly be incorrect, the center distance “a” will become larger than the normal distance, resulting in difficulty of assembly and improper gear engagement. (Fig.3)

A V-groove (60°, 0.3mm deep line) on tip peripheral of the duplex worm tooth marks the reference tooth. The gear set is designated to have a backlash of nearly zero (+/-0.03) when the reference tooth is positioned in alignment with the center of rotation of the worm wheel with the center distance set at the value “a” (Fig.3)

NOTE 1: If the worm and worm wheel are assembled to the standard center distance, it is designated to have a near zero backlash (+/-0.03).

NOTE 2: When the center distance is moved so as to reduce the backlash, V max is the maximum amount that you may shift without causing problems with gear mesh. It is not the recommended adjustment value.

NOTE 4: The allowable torques shown in the table are the calculated values according to the assumed usage conditions. Please see page 294 for more details. The table below shows the allowable worm wheel torques (N.m) at selected worm speeds.

NOTE 3: The shaft O.D., S, has the tolerance +0.2/+0.1 except where ground the tolerance is +0.40/+0.35.

CAUTION: Before assembling or performing any secondary operations, please carefully read the “Application Hints” on page 296.CAUTION: Heat treating the tooth area of these worms is not recommended since it will introduce errors in the lead and pressure angles, producing poor gear mesh.CAUTION: SUW worms may also be used to mate with BG and CG worm wheels.NOTE 1: These worm wheels are profile shifted to create the proper center distance. NOTE 2: The material of BG1-40R1 and 50R1 is CAC502A.

CAUTION: Before assembling or performing any secondary operations, please carefully read the “Application Hints” on page 296.CAUTION: Heat treating the tooth area of these worms is not recommended since it will introduce errors in the lead and pressure angles, producing poor gear mesh.NOTE 1: These worm wheels are profile shifted to create the proper center distance.NOTE 2: The allowable torques shown in the table are the calculated values according to the assumed usage conditions. Please see page 294 for more details. The tables

below show the allowable worm wheel torques (N.m) at selected worm speeds.NOTE 3: The H2 shape worm gears have casting lightening holes in the web.
