T40B
Nominal (rated) torque can be exceeded statically up to
the limit torque. If the nominal (rated) 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 13
"Specifications", page 55.
Measuring dynamic torque
The torque flange can be used to measure static and
dynamic torque. The following apply to the measurement
of dynamic torque:
S The T40B calibration performed for static
measurements is also valid for dynamic torque
measurements.
S The natural frequency f
arrangement depends on the moments of inertia J
and J
of the connected rotating masses and the

torsional stiffness of the T40B.
Use the equation below to approximately determine the
