Loading capacity

Nominal (rated) torque may be statically exceeded up to the limiting torque. If
nominal torque is exceeded, further irregular loadings are not permitted. This
includes longitudinal and lateral forces and bending moments. The limit
values are specified in the chapter called "Technical data", page 48.

8.1 Measuring dynamic torques

The torque flanges can be used to measure static and dynamic torques. The
following applies for the measurement of dynamic torques:
• The T10F calibration made for static measurements is also valid for
dynamic torque measurements.
• The natural frequency f
the moments of inertia J
T10F's torsional stiffness.
Use the equation below to determine the natural frequency f
