If the O-ring is caught by the mating section, it could cause leakage of the lubricant.
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 and durability.
The shape of the shaft installation component may differ from the illustration above, depending on
the customer’s equipment or shape of the reduction gear.
Step 7
Using the hexagonal socket head cap screw and serrated lock washer for a hexagon socket head cap
screw, fix the shaft installation component to the reduction gear.
• Be sure to tighten the specified number of hexagonal socket head cap screws with the specified
tightening torque.
(Reference: “4.2.3. Reduction gear mounting bolts”, “4.2.4. Serrated lock washer for hexagon socket
head cap screw”, and “5.1. Bolt tightening torque”)
If the hexagonal socket head cap screw is 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.
