Loading capability
The nominal torque may be exceeded statically up to the limit torque. With the
nominal torque exceeded, no additional irregular loads such as longitudinal
and transverse forces and bending moments are permissible. The limit values
are specified in the chapter "Technical data", page 38.
6.1 Measuring dynamic torques
The torque flanges can be used to measure static and dynamic torques. The
following applies for the measurement of dynamic torques:
Ÿ The T10F calibration made for static measurements is also valid for
dynamic torque measurements.
Ÿ The natural frequency f
the moments of inertia J
T10F's torsional stiffness.
