Chapter 5 Installation

 For the original series
Perform steps 1 to 6 by taking care regarding the following precautions.
• Prepare an O-ring groove on the shaft installation component and attach an O-ring (I). Step 1
• Align the tapped holes of the shaft installation component with the positions of the mounting holes
of the reduction gear (shaft section), and then attach the shaft installation component to the
reduction gear.
• Using the hexagon socket head cap screw and serrated lock washer for the hexagon socket head cap
screw, temporarily fix the shaft installation component to the reduction gear.
• Take extra care so that the O-ring is not caught by the mounting surface.
• Confirm that the centering shaft of the reduction gear (shaft section) is correctly fitted into the
centering hole of the shaft installation component.
• When designing the shaft installation component, either the inner or outer centering shaft of the
reduction gear (shaft section) should be used.
• Check that there is no foreign matter adhering to the mounting surface.
• If an O-ring cannot be used due to the structure, seal the section using a liquid sealant, etc.
(Reference: “4.2.3 Reduction gear mounting bolts”, “4.2.4 Serrated lock washer for hexagon socket
head cap screw”, “4.2.5. Liquid sealant”, and “4.2.6 O-rings”)

If an O-ring is caught by the mounting surface, 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, such as abnormal noise
and torque irregularity, 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. The installation orientation and necessity
for installing the external load support bearing, case installation component, and plugs for tapped
holes for injecting/draining grease should be determined depending on the customer's equipment.
