Description and applications
Manufacturing and installation tolerances as well as the effects of temperature
cause alignment errors between shafts in drive engineering which can some-
times lead to extreme overload on the bearings.
This may result in increased wear of the bearings and may lead to premature
failure of the encoder. By using couplings, these alignment errors can be com-
pensated, thereby reducing the load on the bearings to a minimum. A distinction
should be made between three different kinds of alignment error: radial, angular
and axial displacement.
Whilst with torsion-free but flexible shaft couplings, axial shaft displacements
produce only static forces in the coupling, radial and angular displacements
produce alternating stresses, restoring forces and moments which may have an
impact on adjoining components (shaft bearings).
Depending on the type of coupling, particular attention should be paid to radial
shaft displacement which should be kept to a minimum.

Couplings
Bellows couplings provide cost-effective connection of the motor
and encoder. They are also able to correct any angular errors
between the drive and encoder.
Spring washer couplings are used with high speeds.
Example: d1 = 10 mm [0.39“] and d2 = 12 mm [0.47“]
