Procedure
1. Using the clamping element (possibly with centering sleeve), mount the motor at the
intended position on the shaft extension.
2. Using screws (3) clamp the tapered ring (2) onto the tapered sleeve (1). Initially tighten all
screws diagonally so that they are hand tight (5 to 8 Nm).
3. Then tighten all of the screws (3) diagonally using a torque wrench. When doing this, the
screw may only be tightened through a maximum of ¼ of a turn. Repeat this operation
until all of the the screws are tightened with the specified torque using a torque wrench.
When doing this, comply with the specified torques. Then check that the motor runs true.
4. Then check the gap between the tapered sleeve (1) and tapered ring (2) and between the
tapered sleeve (1) and the forcing-off screws (4). There must be a minimum gap of
there is a risk that the clamping element will not fulfill its function (excessively low joint
interference and therefore inadequate torque transmission).
Causes could be for hollow shaft extension:
The clamping elements have been mounted.
