6.3.2Replacing the motor or the gearbox
@ WARNING
Prerequisites
Dismounting, motor only
GREAT MASS OR FALLING PARTS
•In the case of a vertically installed linear axis, secure the moving parts to keep them from falling down.
•Mount the product in such a way (tightening torque, securing screws) that the axis and mounted parts cannot come loose even in the case of fast acceleration or continuous vibration.
•Note that vertically installed linear axes may lower unexpectedly.
Failure to follow these instructions can result in death, serious injury or equipment damage.
The motor or the gearbox are coupled by means of a preloaded elas- tomer coupling.
Unless otherwise specified, the standard tightening torques indicated on page 47 apply.
See chapter 7 "Accessories and spare parts" for suitable spare parts. You need a set of Allen keys and a torque wrench with hexagon socket.
Secure the motor to keep it from falling down.
Remove the 4 screws and washers at the motor.
Pull the motor and the clamping hub off of the motor adapter plate. This requires a greater force of up to 450 N.
Loosen the clamping screw at the clamping hub.
Pull the clamping hub off the motor shaft.
Dismounting, gearbox only
See the gearbox manual for details on removing a motor from the gearbox.
