6.6 Installing a load

Combination type parallel gearhead or round shaft type
When installing a load on the motor (gearhead), align the center of the motor output shaft (gearhead output shaft) with
the center of the load shaft.
Note
•
When coupling the motor (gearhead) with a load, pay attention to centering, belt tension,
parallelism of pulleys, etc. Also, securely afx the tightening screws of the coupling or pulleys.
•
When installing a load, do not damage the motor output shaft (gearhead output shaft) or
bearing. Forcing in the load by driving it with a hammer, etc., may break the bearing. Do not
apply any excessive force to the output shaft.
•
Do not modify or machine the motor (gearhead) output shaft. The bearing may be damaged or
motor (gearhead) may break.

Output shaft shape
Combination type parallel shaft gearhead
A key groove is provided on the output shaft of each combination type parallel shaft gearhead. Form a key groove on
the load side and afx the load using the supplied parallel key.
Round shaft type
A at section is provided on the motor output shaft of each round shaft type. Apply a double-point screw, etc., at the
at section to securely afx the load and prevent it from spinning.

How to install a load
Using a coupling
Align the centerline of the motor (gearhead) output shaft with the centerline of the load shaft.
Using a belt
Adjust the motor (gearhead) output shaft to lie parallel with the load shaft and form right angles between the output
shaft/load shaft and the line connecting the centers of both pulleys.
Using a gear
Adjust the motor (gearhead) output shaft to lie parallel with the gear shaft and allow the output shaft to mesh correctly
with the centers of the gear teeth.
When using the output axis tip screw hole of a gearhead
Use a screw hole provided at the tip of the output shaft as an auxiliary
means for preventing the transfer mechanism from disengaging.
