The usual method of adjusting the backlash of a worm gear assembly is to modify the center distance. Once assembled, such adjustment requires a major rework of the gear housing. The use of duplex worm gears and worm wheels allows backlash adjustment to be made by axially shifting the worm. This simplifies greatly the assembly and mainte-nance operations.

■ Description of Duplex Worm Gear Pair

These are designed so that moving the pinion axially by 1mm changes the backlash by 0.05mm.

Features

These are designed so that moving the pinion axially by 1mm changes the backlash by 0.02mm.

● Characteristics of Racks & PinionsAdvantages Description

Simple component including a small number of parts This simple component does not include parts such as balls or retainers, so there is no concern about missing pieces when assembling or disassembling.

Capable of handling large loads Racks with large modules can be used in large loadings.

Compact component systems can be created Allows compact component usage for light loads, while downsizing is possible, more than a ball screw mechanism.

High power transmission efficiency Approximately 98% power transmission efficiency is implemented. (Resistance against lubricant agitation or bearing is not included.)

Rapid feeding It enables quick feeding if the pinion has a large radius,

Has no limitation in length Racks can be joined lengthwise, conversely, in case of using a screw mechanism, defection must be considered and the maximum length should be within 2 meters.

Designed for flexibly Flexibly designed within certain conditions, materials, heat treatments, shapes etc., easily adapting to most machines.

High accuracy Applying tooth-grinding, pitch errors can be lessened

Used in food machine equipments MC Nylon Plastic or Stainless Steel products are available.

Disadvantages DescriptionBacklash evident For smooth revolution, essential backlash is required. In the case of positioning forward reverse revolution, backlash is not a concern.

Lubrication required Lubrication is necessary for metal racks. For plastic racks, using light loads, lubrication is not required, however, accuracy is low.

● Characteristics of Ball ScrewsAdvantages Description

High power efficiencytransmission High power transmission efficiency, exceeding 90%.

High accuracy Grinding treatment allows the creating of high-precision ball screws.

Rapid feeding High-helix lead screws enable rapid feeding.

No backlash is present Pressurizing eliminates backlash.

Disadvantages DescriptionLimited in length Practical limit would be approximately 2m due to warpage.

Special purposes are difficult to create. Since it is difficult to create special-purpose ball screws, the machine must be set up in accordance with the shape of the ball screw.

One turn

Pitch

The reference pitch of a metric module is computed by multiplying the number of module by π(3.14159). For example, the reference pitch of m3 rack is 9.425mm (3 x π). When using a rack and a pinion in linear motion applications, the fact that the pitch is not an integral number presents a difficulty in accurate positioning. This problem is solved by using circular pitch racks and pinions where one rotation of a pinion moves it precisely 50, 100, 150, to 600. The difference in movement of one rotation of 30-teeth CP10 vs. SS3 spur gears is illustrated on the left.

3. Select by Gear StrengthGear Strength is one of the most important factors inselecting gears.

■ Definition of Bending Strength

The allowable bending strength of a gear is defined as the al-lowable tangential force at the pitch circle based on the mu-tually allowable root stress of two meshing gears under load.

Example of failure due to insufficient bending strength.

■ Definition of Surface Durability

The surface durability of a gear is defined as the allowable tan-gential force at the pitch circle, which permits the force to be transmitted safely without in-curring surface failures.

Example of defacement due to insufficient surface dura-bility.

Step 1 Approximate the type of gear, strength and torque load.

Step 2 Make a tentative selection based on the torque load using the printed version of the KHK catalog, or the Web catalog.

■ The KHK catalog is used for the tentative selections. ■ The Web catalog is used for the tentative selections.

Step 3 After calculating the required strength using the actual conditions of usage, examine the se-lection mode in Step 2.

If the Web catalog is used, the strength can be easily confirmed.

Please feel free to contact:

１． Follow all applicable safety regulations (Labor, Safety, and Sanitation Regulations) in in-stalling and operating our products.

２． Adhere to the following procedures when installing, dismantling or inspecting our prod-ucts.① Turn off the power.② Do not place any part of your body in harm's way.③ Wear proper attire and protective gear appropriate for the task.

We consider safety to be of utmost importance. Please consider the following issues in order to prevent danger in handling, assembling, and operating KHK products.

Attention　Prevention of Accidents１． Please read the “CAUTION” notes before using our products in your applications.２． Please avoid using the products in an environment where it may cause adverse effects.３． KHK Products are made in accordance with ISO 9000 Quality Standard. However, if any

defective products are found, please contact the dealer.

MARYLAND METRICS email: [email protected]

Precautions on Applications

Precautions on Performing Secondary Operations

Precautions on Assembling

Precautions on Starting Operations１． Before operating, check the following:

　 ① Are the gears firmly mounted on the shafts?　 ② Have you eliminated uneven tooth contact?

③ Does the gear mesh have a proper amount of backlash? (Please avoid the condition of no backlash)

　 ④ 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． The following are the gear lubrication methods for general use.(a) Grease Lubrication(b) Splash Lubrication (Oil Bath Method)(c) Forced Oil Circulation Lubrication

Check lubrication after start up, sometimes, when the unit is initially being operated, lubricating oil deteriorates rapidly. ４． If there is unusual noise or vibration at the start up, please recheck the gears and correctness of the assembly. Some of the

methods for achieving noise reduction are:(a) High Precision(b) Fine Tooth Surface Finish(c) Accurate Tooth Contact

１． KHK products are individually packaged to avoid damage during shipping. In case you find rust, scratches, dents or other problems when you unpack your gears, please contact the dealer where you made your purchase.

２． Depending on how they are handled, it is still possible to deform or break gears. Please be sure to handle gears care-fully, especially the long racks or ring gears, as they are easily deformed.

１． KHK Gears are designed so to give the proper backlash as long as assembled in accordance with the normal value (theoretical values) of the center distance. For a pair of gears, the center distance tolerance is specified to the plus side of tolerances H7 to H8. However, in case of using multiple gear trains, please aim for near-zero by setting to a plus-tol-erance, or minus-tolerance.

２． When you assemble gears, please read through the information “Points of Caution in Assembling” on the first page of each product series section.

１． We can not guarantee the precision of gears once a customer performs a modification (secondary operation) on any gears.

２． When you apply additional secondary operations on KHK Stock Gears, please read through the information “Cautions on Performing Secondary Operations” on the first page of each product series section.
