6.3.2 Replacing the motor or the gearbox
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.
Prerequisites 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.
Dismounting, motor only
̈ 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.
@ WARNING
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.
