5.4.4 Coupling mounting
Advantage: Simple design, a standard motor can be used.
Disadvantage: As a result of its function, a coupling must be flexible and therefore has a
negative impact on the positive characteristics and features of a directly driven load. The
coupling reduces the drive train stiffness.
Bearings can be prematurely damaged, if force transmission elements apply too much load
to the shaft end as a result of radial forces.
• When using mechanical transmission elements, ensure that the maximum limit values
specified in the radial force diagrams are not exceeded.
