5.2.2. Installing the input gear
 For straight shafts (attached to motor shaft tip)
The following is an example when fixing the input gear to the motor shaft using a bolt.
Perform steps 1 to 3 by taking care regarding the following precautions.

Avoid impact to the motor shaft when attaching the input gear.

The outer diameters of the bolt head and seal washer should be smaller than the root circle diameter
of the input gear.

Avoid impact to the motor shaft when attaching the input gear, as it could damage the motor.

If the outer diameters of the bolt head and seal washer are larger than the root circle diameter of the
input gear, the bolt and seal washer will interfere with the spur gear, and therefore, the gear cannot
be installed or could be damaged.
• Attach a key to the motor shaft. Step 1
• Attach the input gear to the motor shaft. Step 2
• Check that there is no foreign matter adhering to the mounting surface.

If any particle adheres to the mounting surface, appropriate installation accuracy cannot be obtained.
It could cause deterioration of performance, such as abnormal noise and vibration, and also lead to
damage of the motor.
• Fix the input gear to the motor shaft using a hexagon socket head cap screw. Step 3
• Using a thread-locking sealant for screws, lock the hexagon socket head cap screw.

If necessary, seal the area with a seal washer, etc. Otherwise, it could cause the leakage of
lubricant.

Check the depths of the input gear hole and motor shaft screw before selecting an appropriate size
and length of the hexagon socket head cap screw.
