Loading capacity
56 A3276-8.0 HBM: public T40FM
9 Loading capacity
Nominal torque can be exceeded statically up to the limit
torque. If the nominal torque is exceeded, additional ir
regular loading is not permissible. This includes longitud
inal forces, lateral forces and bending moments. Limit
values can be found in Chapter 14 "Specifications" on
Page 78.
Measuring dynamic torque
The torque flange can be used to measure static and dy
namic torque. The following apply to the measurement of
dynamic torque:
S The T40FM calibration performed for static measure
ments is also valid for dynamic torque measurements.
S The natural frequency f
0
of the mechanical measuring
arrangement depends on the moments of inertia J
1
and J
2
of the connected rotating masses and the tor
sional stiffness of the T40FM.
