Foot Version Assembly
The housing of the sensor is designed as a bearing block. A full coupling must
be
installed at both shaft ends. By this, inevitable misalignments can be balanced, which
can occur during the period of operation.
If no couplings are used, very large transverse forces can affect the sensor. In addition,
large forces occur on the bearings in drive and output, which limit their life span very
strongly.
Furthermore large bending moments occur in the shaft. At small torques (< 20 N·m)
connect the sensor electrically during the assembly and observe the signal, the
measurement signal may not exceed the limit values
Shafts have to be cleaned with solvent (e.g. acetone) before the assembly
No foreign bodies may adhere to them.
Shift couplings on shaft (use entire clamping length of the coupling) and align shafts.
Absolutely note that the data of the couplings (axis offset, angular offset, tension, compression) are not exceeded.
Caution:
During the assembly inadmissibly large forces may not act on the sensor or the couplings.
