Step 4
• Attach the shaft installation component to the reduction gear.
• Confirm that the centering shaft of the reduction gear is correctly fitted into the centering hole of
the shaft installation component.
• Check that there is no foreign matter adhering to the mounting surface.
• Using the reduction gear mounting bolt and serrated lock washer for hexagon socket head cap
screw, fix the shaft installation component to the reduction gear.
• Be sure to tighten the hexagon socket head cap screws with the specified tightening torque.
(Reference: “4.2.2. Reduction gear mounting bolts”, “4.2.3. Serrated lock washer for hexagon socket
head cap screw”, and “5.1. Bolt tightening torque”)
If the hexagon socket head cap screws are not
tightened with the specified torque, the reduction gear
does not deliver the designed performance. In addition,
it could cause injury and damage to the customer’s
device and the reduction gear.
If there is foreign matter adhering to the mounting
surface, the mounting surface of the reduction gear
may be deformed, which could cause deterioration of
performance, such as abnormal noise and torque
irregularity and durability.
When installing the installation component, take extra care not to cover the tapped holes for
injecting/draining grease. If the tapped holes are covered, it will be difficult to replace the lubricant.
(2) When the product cannot be installed with the motor flange already mounted
Perform steps 1 to 5 by taking care regarding the following
precautions.
Step 1
• Loosen the hexagon socket head cap screws
securing the motor flange, and then remove the
motor flange from the reduction gear.
• As the hexagon socket head cap screws will be
reused when assembling, store them in a safe place.
