2.3 Cantilever and axial force diagrams
For a general description, please refer to the documentation “General Section for
Induction Motors”.
2.3.1
Cantilever force
!
Caution
When using mechanical transmission elements, which subject the shaft end to a
cantilever force, it should be ensured that the
maximum limit values, specified
in the cantilever force diagrams, are not exceeded
.
Note
Shaft heights 180 and 225
For applications with an extremely low cantilever force load, it should be ensured
that the motor shaft is subject to a
minimum cantilever force load as specified
in the diagrams
. Lower cantilever forces can cause the cylindrical bearings to roll
in an undefined fashion. This results in increased bearing wear and higher noise.
For these applications, bearing designs for a coupling out-drive should be
selected.
The maximum permissible and the minimum required cantilever forces are shown
in the following diagrams.
