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. (Reference: Fig. 4-2 in “4.2.3. Serrated
lock washer for hexagon socket head cap screw”)
• Be sure to tighten the hexagon socket head cap screws with the specified tightening torque.
(Reference: Table 5-1 in “5.1.1 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 shaft installation component, take extra care not to cover the tapped holes for
injecting/draining grease. If the tapped holes are capped, it will be difficult to replace the lubricant.
