Mounting the coupling
46
A larger shaft displacement, for example when switching a drive unit on and
off, is permissible for a short time. The maximum permissible angular, radial
and axial displacements must not occur all at the same time.
The permissible coupling misalignment limits are dependent on multiple factors such
as e.g. coupling size, element hardness, operating speed and torque stress. The
guideline values listed in the following table apply to a medium element hardness and
a typical rotational speed up to 1500 rpm
