Note
•
Do not disassemble the gearhead from the motor.
•
When using the gearhead flange to mount the geared motor to equipment, proper alignment between the
hollow shaft inside dimension and the load shaft is necessary. Keep the alignment tolerance within
0.02 mm (0.0008 in.). Insufficient alignment may result in damage to the gearhead internal bearings.
•
On rare occasions, a small amount of grease may ooze out from the gearhead. If there is a concern
over possible environmental damage resulting from the leakage of grease, provide an oil tray or similar
oil catching mechanism in order not to cause a secondary damage. Oil leakage may lead to problems
in the customer’s equipment or products.
For the motor equipped with cooling fan (90 W)
When installing a motor with cooling fan onto a device, leave 10 mm (0.39 in.) or more behind the fan cover or open a
ventilation hole so that the cooling inlet on the back of the motor cover is not blocked.
3.3 Installing a load
Parallel shaft • combination type, round shaft type
When installing a load on the motor (gearhead), pay attention to the following points.
•
Align the centerline of the motor output shaft (gearhead output shaft) with the centerline of the load.
•
For the parallel shaft�combination type, a key slot is provided on the output shaft of the gearhead.
Form a key slot on the load side and secure the load using the supplied parallel key.
Note
•
When coupling the motor (gearhead) with a load, pay attention to centering, belt tension, parallelism of
pulleys, etc. Also, firmly secure the tightening screws of the coupling or pulleys.
•
When installing a load, do not damage the motor output shaft (gearhead output shaft) or bearing. Do
not apply excessive force onto the output shaft of the gearhead using a hammer or other tools. Doing
so may cause damage to the output shaft or bearings.
•
Do not modify or machine the motor (gearhead) output shaft. The bearing may be damaged or motor
(gearhead) may break.
•
When using the output shaft end tapped hole of a gearhead
Use a tapped hole provided at the end of the output shaft as an auxiliary means for preventing the transfer mechanism from
disengaging.
