2.1.2 SUPPORTED INSTALLATION
The measuring shaft is supported by the torque sensor housing, which itself is fixed to the test bench frame
by means of a support unit (
see Fig.2-2
). Here, couplings with two degrees of freedom must be used in or-
der to avoid hyperstatic mountings.

2.1.2.1 ADVANTAGES
▪ Increased critical speed due to less shaft bending.
2.1.2.2 DISADVANTAGES
▪ Longer overall length of the test bench due to the use of double-element couplings.
▪
Increased price due to the higher price of double-element couplings.
Supported installations are required when larger misalignments between the different ele-
ments of the system are a possibility, as well as with high rotational speeds.
High-performance couplings can be realized by mounting flanges directly onto a splined torque trans-
ducer shaft. (Not available on all models.)
