Coupling to the Machine
You can couple the Servomotor to the machine with either a coupling or a belt.
Use the following procedures.
8.2.1
Using a Coupling
1.
Wipe off all of the anticorrosive coating from the motor shaft.
2.
If you are using a Servomotor with a Key, attach the key enclosed with the Servomotor
or the specified size of key to the shaft.
3.
Confirm that the centering accuracy is within the specified range using a dial gauge or
other means.
If a dial gauge is not available, slide the coupling along both shafts and make adjustments so that it
does not catch.
•
Use a flexible coupling that is designed for Servomotors. We recommend that you use a dou-
ble-spring coupling, which provides some tolerance in eccentricity and deflection.
•
Select a suitable size of coupling for the operating conditions. An inappropriate coupling may
cause damage.
When you attach the key to the motor shaft, do not subject the key groove or shaft to direct
shock.
Important
Important
Measure this distance at four different positions on
the circumference. The difference between the
maximum and minimum measurements must be
0.03 mm or less.
Even within this range, make adjustments to
increase centering accuracy as much as possible.
Centering Accuracy
Note: When making the measurements, turn
the coupling and motor shaft together.
