Installing A Load - Vexta aStep AS Series Operating Manual

Installing a load

When connecting a load to the motor, align the centers of the motor's output shaft and load
shaft.
Optional flexible couplings are available (sold separately).
Direct coupling
Align the centers of the motor's output shaft and load shaft in a straight line.
Using a belt drive
Align the motor's output shaft and load shaft in parallel with each other, and position both
pulleys so that the line connecting their centers is at a right angle to the shafts.
Using a gear drive
Align the motor's output shaft and gear shaft in parallel with each other, and let the gears mesh
at the center of the tooth widths.
Using a geared motor
With a geared motor, to connect a load to the gear output shaft having a key groove, first
provide a key groove on the load and fix the load with the gear output shaft using the supplied
key.
Note
• When coupling the load to the
motor, pay attention to the
centering of the shafts, belt
tension, parallelism of the
pulleys, and so on.
Securely tighten the coupling
and pulley set screws.
• Be careful not to damage the
output shaft or the bearings
when installing a coupling or
pulley to the motor's output
shaft.
• Do not modify or machine the
motor's output shaft. Doing so
may damage the bearings and
destroy the motor.
