Chapter 5 Installation

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”.
Installing the servomotor, pulley, and reduction gear
5.2.2.
This section describes the procedures for installing the servomotor and reduction gear (input side) for the
straight and right angle input units and installing the pulley and reduction gear (input side) for the pulley
input unit, and the installation direction for the hollow shaft series.
(1) For the straight input type and right angle input type
Perform steps 1 to 7 by taking care regarding the following precautions.
Step 1
• Wipe the outside of the servomotor shaft and the clamping surface inside the coupling with a clean
cloth.
(Check that the clamping bolt is not tightened.)
• When using a bushing, wipe the inside and outside of the bushing using a clean cloth.
• Before installation, check that there are no scratches on the inside of the coupling, bushing, and
motor shaft that could interfere with installation.
• Make sure that there is no foreign material or oil on the outside of the servomotor shaft, the clamping
surface of the coupling, or the inside and outside of the bushing.
Step 2
• Align the clamping bolt of the coupling with the motor flange hole.
• When inserting the bushing, align the slit of the bushing and the slit of the coupling. (See Fig. 5-7 for
the positional relationship between the bushing and coupling.)
• When using the bushing with a V groove on the circumference, orient the V groove toward the
reduction gear side and then insert the bushing.
