If the slits of the bushing and coupling are not aligned, proper tightening force cannot be achieved.
When using the bushing with a V groove on the circumference, orient the V groove toward the
reduction gear side. If the direction is not correct, proper tightening force cannot be achieved.
Step 3
• If necessary, wipe off the grease adhering to
the mounting surface of the motor flange and
the servomotor, and then apply a liquid sealant
onto this surface.
(Reference: Table 4-4 in “4.2.4 Liquid
sealant”)
Step 4
• Align the motor shaft with the inside of the coupling or the bushing and insert the servomotor in a
straight line. Confirm that the mating part of the motor is aligned with the mating part of the motor
flange when inserting the servomotor.
• If the motor shaft has a keyway, set the motor so that the keyway of the motor shaft is positioned on
the opposite side of the slit of the coupling (see Fig. 5-9) and then insert the motor.
If the keyway of the servomotor and the slit of the coupling are not positioned as specified in this
manual, proper tightening force cannot be achieved.
