7) Each type of irregular stress can only be permitted with its given static load limit (bending moment, lateral or axial load, exceeding the nominal (rated)
torque) if none of the others can occur. Otherwise the limit values must be reduced. If for instance 30 % of the bending limit moment and also 30 % of the
lateral limit force are present, only 40 % of the axial limit force are permitted, provided that the nominal (rated) torque is not exceeded. With the permitted
bending moments, axial, and lateral limit forces, measuring errors of about 0.3 % of the nominal (rated) torque can occur.
8) With static loading
9) Static and dynamic
10) The nominal rated) torque must be exceeded
Notes:
• Extremely high dynamic vibration, velocity, accelerations and running at shaft resonance
have to be avoided, otherwise measuring can be wrong or transducer can be damaged
(rotational acceleration max. 30000rpm/s)!
