9 Load‐carrying capacity
Nominal (rated) torque can be exceeded statically up to the limit torque. If the
nominal (rated) torque is exceeded, additional irregular loading is not permissi­
ble. This includes longitudinal forces, lateral forces and bending moments.
Limit values can be found in
Chapter 13 “Specifications”, page 50 .
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:

The T40B calibration performed for static measurements is also valid for
dynamic torque measurements.
S
The natural frequency f

of the mechanical measuring arrangement
depends on the moments of inertia J

and J
2
of the connected rotating
masses and the torsional stiffness of the T40B.
