Step 4
• Align the mating part of the motor flange with that
of the reduction gear. Then, closely attach the
motor flange to the reduction gear while adjusting
the position of the motor flange fixing hole.
• Confirm that the centering shaft of the motor
flange is correctly fitted into the centering hole of
the reduction gear.
• Check that there is no foreign matter adhering to
the mounting surface.
• Make sure that the matching surface of the motor
flange and the matching surface of the reduction
gear are in close contact. If either of them is tilting
or there is a gap, remove the motor flange and
perform step 4 again.
• Use the stored hexagon socket head cap screws, which have been removed in step 1 for “(2) When
the product cannot be installed with the motor flange already mounted”.
• Using the hexagon socket head cap screw, fix the motor flange and 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” 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.
Step 5
• Incorporate the reduction gear into the customer’s equipment according to step 4 in “(1) When the
product can be installed as is”.
