Aligning the coupling
CAUTION!
Increased rate of wear to the flexible coupling element due
to inadequate alignment of the drive unit and the driven
machine.
When aligning the drive unit and the driven machine, adhere
to the values specified for the angular-, radial and axial
displacement.
Free-standing, non-flanged units require careful alignment of the coupling in order to
ensure proper functioning of the coupling and to avoid premature wear to the
element.
Flange couplings must be aligned from the shaft-side coupling half to one of the
machined surfaces of the engine flywheel or engine housing. With shaft couplings, the
angular and radial displacements between the two coupling halves are determined by
applying the usual dial gauge method. The alignment instructions for the other system
components must also be taken into account.
Precise alignment has a positive effect on the service life of the coupling and
other system components. We therefore recommend using only up to 20% of
the permissible radial and angular displacements for the alignment of the
installation.
Determine the alignment, for example by applying the usual dial gauge method to
machined surfaces.
Proceed as follows to align the coupling:
Check the alignment of the coupling from the shaft-side coupling half to a
machined surface of the flywheel or the engine housing, see the figure below.
