Options to optimize the smooth running characteristics of the mounting
You can check that the system runs true during procedures 2 and 3. You align the motor by
specifically tightening the screws (3). If the clamping screw (3) is over-proportionally
tightened, then at this position the motor is lifted off from the shaft extension.
If, after tightening to the final torque, the true running check indicates an excessively high
deviation, then release all of the clamping screws (3) and repeat tightening procedures 2 and
3 - checking the true running and tightening the clamping screws as required (3).
Removing
Procedure
If, when removing the clamping element, after removing the clamping screws (3) the tapered
ring (2) cannot be released, then proceed as follows:
1. Release the lock nut (5) and turn this until it comes into contact with the head of the
forcing-off screw (4).
2. Rotate the forcing-off screws (4) in the tapered ring (2) until they are in contact with the
tapered sleeve (1).
3. Screw in the forcing-off screws (4) one after the another through ¼ of a turn until the
tapered ring is released.
The tapered ring has been released.
❒
If the motor cannot be released from the shaft extension, for an appropriate shaft extension
design, use the forcing-off screws to press the tapered ring until it comes into contact with
the shaft shoulder. The motor is pressed from the shaft extension by turning the forcing-off
screws further (4).
When reusing the clamping element, turn the forcing-off screws back and secure them using
the lock nuts (5).
When certain requirements exist, e.g.
● different diameter
● restricted mounting space
● thermal insulation
● electrical isolation
