5.2.3. Installing the motor
Install the motor with an attached input gear in the reduction gear already mounted with the motor mounting
flange.
The following is an installation example when sealing the input gear with an oil seal.
Perform steps 1 to 3 by taking care regarding the following precautions.
Step 1
Attach an oil seal to the motor mounting flange.
Step 2
Install the input gear on to the motor shaft, and then directly insert the motor into the reduction gear.
• Do not forcibly press down on the motor.
• Take extra care so that the gear section of the input gear does not scratch the lip surface of the oil seal.
• Take extra care so that no scratch will be made on the gear section due to interference between the
input gear and spur gear.
If the motor is forcibly pressed down, it could damage the input gear, spur gear, and motor.
If the gear section of the input gear scratches the lip surface of the oil seal, it could cause leakage of
the lubricant.
If the gear section is scratched due to interference between the input gear and spur gear, it could
cause abnormal noise.
Step 3
Using the hexagonal socket head cap screw, fix the motor to the motor mounting flange.
• Confirm that the centering location of the motor is correctly fitted into the centering location of the
motor mounting flange.
• Check that there is no foreign matter adhering to the mounting surface.
If foreign matter adheres to the mounting surface, appropriate installation accuracy cannot be
obtained. It could lead to premature damage of the reduction gear or motor.
Note: There are various ways to install the motor, depending on the shape of the reduction gear or
customer’s equipment. For the installation methods other than the above examples, check the
“External dimensions” drawings and delivery specifications. If anything is unclear, refer to our
