2.2.2 AXIAL FORCES (THRUST)
In suspended installations, pure thrust forces (F
A
see Fig.2-4
) have practically no effect on the measurement
results, as they do not provoke any deformation of the shaft that could influence the measurement.
In supported installations, axial thrust forces produce a strain on the bearings. This leads to premature
wear of the bearings and an increase of the residual torque. In this case, the maximum allowed axial force
for the transducer is lower than the allowed force in the case of suspended installation.
It is important to avoid the simultaneous application of radial and axial forces on the mea-
suring shaft of a transducer, especially with supported installations.
The following table lists the maximal axial forces F
A
allowed for TMB, TM and TMHS Series transducer shafts
in suspended and supported installations.
