Coupling Mounting - Siemens SIMOTICS T-1FW3 Configuration Manual

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.
NOTICE
Premature bearing damage
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.
