For straight shafts (attached to motor shaft base)
The following is an example when fixing the input gear to the motor shaft using a set screw.
Perform steps 1 to 3 by taking care regarding the following precautions.
• Avoid impact to the motor shaft when attaching the input gear.
• Keep in mind that the mounting surface is clean, degreased and dry.
Avoid impact to the motor shaft when attaching the input gear, as it could damage the motor.
If any particle adheres to the mounting surface, appropriate installation accuracy cannot be obtained.
It could lead to premature damage of the reduction gear or motor.
Step 1
Attach a key to the motor shaft.
Step 2
Attach the input gear to the motor shaft.
Step 3
Tighten the input gear to the motor shaft using the set screw.
Using the locking agent for screws, lock the set screw.
If a thread-locking sealant is not used for the set screw, a clearance will be generated in the keyway,
which could cause deterioration of performance, such as abnormal noise and vibration, and also
lead to damage of the motor.
