8 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 the chapter
"Specifications" (Chapter 13, Page 34).
Measuring dynamic torque
The T40MS torque flange can be used to measure static and dynamic torques. The
following rule applies to the measurement of dynamic torque:
•
The transducer calibration performed for static measurements is also valid for
dynamic torque measurements.
•
The natural frequency f0 of the mechanical measurement setup depends on the
moments of inertia J1 and J2 of the connected rotating masses, and the torsional
stiffness of the transducer.
Use the equation below to approximately determine the natural frequency f0 of the
mechanical measuring arrangement:
•
The permissible mechanical vibration bandwidth (peak-peak) can also be
found in the specifications.
