18.3 Additional drive element

18.3.1 Rated torque loss is exceeded

18.3.2 Min. ratio (K) is higher than max. ratio (K)

Note!

The constant torque loss at the output end of the additional drive component is xxx. Thus the rated torque

loss of yyy is exceeded.

Cause Effects Possible remedies

The general ratio is characterised by

the "permissible torque". The effi-

ciency in this operating point defines

the max. constant loss of yyy. Accord-

ing to this definition, the constant

torque loss exceeds the limit value.
