Loading capacity

9 Loading capacity
Nominal torque can be exceeded statically up to the limit torque. If the nominal
torque is exceeded, additional irregular loading is not permissible. This includes
longitudinal forces, lateral forces and bending moments. Limit values can be
found in Chapter 14 "Specifications" on Page 63.
Measuring dynamic torque
The torque flange can be used to measure static and dynamic torque. The fol­
lowing apply to the measurement of dynamic torque:
S The T40FM calibration performed for static measurements is also valid for
dynamic torque measurements.
S The natural frequency f
pends on the moments of inertia J
and the torsional stiffness of the T40FM.
Use the equation below to approximately determine the natural frequency f
