Chapter 4 Preparations for installation
9

The actual components may differ from the required components shown in the above illustration,
depending on the customer’s equipment.

The above is an illustration of the bolt-clamping output shaft type from the catalog. Note that a pin is
required for the pin/bolt clamping output shaft type.

Seal the shaft mounting surface of the reduction gear and shaft installation component using liquid
sealants.

If liquid sealants cannot be used, use an O-ring (I) and high-torque seal washer.
4.2.1. Input gear

Prepare the input gear for motor rotation into the reduction gear. For the design of the input gear,
refer to “Appendix: Design Scheme of Input Gear”.

The prepared gear teeth must meet the specifications and materials described in “Appendix: Design
Scheme of Input Gear”. An operation error due to damage or wear of the gear teeth could cause
injury.

If the input gear has an oil sealing surface, take extra care so that no scratch will be made on the oil
sealing surface when handling the input gear. Any scratches could cause leakage of the lubricant.

Take extra care so that no scratch will be made on the gear tooth section when handling the input
gear. Any scratches could cause abnormal noise.

The customer is requested to prepare the oil seals used for sealing the circumference of the input
gear.

The standard input gear, which is an optional component, is not provided with installation
components such as bolts and keys. Prepare them as necessary at each customer’s site.
4.2.2. Flange and its installation components
 Motor mounting flange

Prepare the motor mounting flange for fixing the motor on the reduction gear input side.

In order to avoid contact with reduction gear components, refer to the sizes indicated in the “Outer
dimensions” drawings when designing the motor mounting flange.

Confirm that a tapped hole for injecting/draining grease is installed in the motor mounting flange. It
will be necessary for filling or replacing the lubricant after installing the reduction gear.
