Mounting the drive elements

Reduce the bending torque load applied to the shaft and the bearing by appropriately arranging
the output elements.
Mount the output elements as close as possible to the motor bearing.
low stress on shafts and bearings
Mount or remove the power output elements (e.g. couplings, gear wheels, belt pulleys) using
suitable devices only (see figure).
• Use the threaded hole in the shaft extension.
• If required, heat up the output elements before mounting or removing.
• When removing the output elements, use an intermediate disk to protect the centering in the
shaft extension.
Figure 5-2
• If necessary, completely balance the motor together with the output elements according to
ISO 1940.
Note
Motors with feather key are half-key balanced. The motors have been balanced with half a
feather key.
The motor dimensions can be found in section "Dimension drawings (Page 107)".
