Installing the input spline
5.3.2.
For straight shaft (with a key and tap)
The following is an example when fixing the input spline to the motor shaft using a hexagon socket head
cap screw.
Perform steps 1 to 3 by taking care regarding the following precautions.
• Avoid impact to the motor shaft when attaching the input spline.
Avoid impact to the motor shaft when attaching the input spline, as it could damage the motor.
Step 1
• Attach the key (4) to the motor shaft.
Step 2
• Attach the input spline (1) to the motor shaft.
• Check that there is no foreign matter adhering to the mounting surface.
If there is foreign matter adhering 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.
Step 3
• Fix the input spline retainer (2) to the motor shaft using the hexagon socket head cap screw (3).
• Using a thread-locking sealant for screws, lock the hexagon socket head cap screw (3).
Check the depths of the input spline retainer hole and motor shaft screw hole before selecting an
appropriate size and length of the hexagon socket head cap screw.
