4.1 Solid shaft version
The measuring system is connected to the drive shaft via an elastic coupling. The
coupling absorbs any deviations in the axial and radial direction between the
measuring system and drive shaft. This prevents excessive load on the bearing.
The centering collar with selective fit is used for centering in relation to the shaft. The
device is fixed to the machine using three screws in the flange.
All the fixing screws must be secured to stop them coming loose unintentionally.
4.1.1 Requirements
As the installation is application-dependent, the following instructions do not
claim to be exhaustive.
 An appropriate coupling with positive-locking connection must be used in
the application.
 The instructions and installation specifications provided by the coupling
manufacturer must be observed.
 In particular you must ensure that
– the coupling is suitable for the specified speed and the potential axial
offset
– the device must be installed on a greaseless shaft
– the coupling and measuring system must not have an axial load
– the clamping screws must be tightened with the torque defined by the
coupling manufacturer
– the coupling screws must be secured to stop them coming loose
unintentionally.
 The coupling fixing should prevent axial slippage of the measuring
system on the drive shaft, see Figure 2, 1 .
 Positive locking using a parallel key/groove combination (Fig. 2, 2 )
should prevent radial slippage of the measuring system on the drive
shaft; a coupling with groove should be used for this purpose.
