Shift the power packs in axial direction until the mounting dimension l
3
or l
7
(table 1 or 3) has been achieved.
!
With the assembly please make sure that the spline of the hub is fully covered by the
internal spline of the flange. (Please observe mounting dimensions l
3
or l
7
.) Disregarding
this advice may cause damage to the coupling.
If the power packs are already firmly assembled, shifting the hub axially on the shaft allows for setting the
distance dimension.
The
BoWex
®
flange couplings compensate for positional deviations of the machine components to be connected
up to the data specified in table 12.
With alignment, the radial and angular displacement should be kept as small as possible, because the service life
is increased in this way if the operating conditions are otherwise maintained.
The
BoWex
®
flange coupling has to be aligned from the coupling hub on the shaft side towards one of the
machined surfaces of the flywheel or machine.
!
In order to ensure a long service life of the coupling, the shaft ends have to be accurately
aligned. Please absolutely observe the displacement figures specified (see table 12). If the
figures are exceeded, the coupling will be damaged.
The more accurate the alignment of the coupling, the longer is its service life.
Please note:
The displacement figures specified in table 12 are maximum figures which must not arise in parallel. If radial
and angular displacements arise at the same time, the permissible displacement values may only be used
proportionally (see illustration 12).
The displacement figures specified are general standard figures that apply up to an ambient temperature of
80 °C, ensuring a sufficient service life of the
BoWex
®
coupling.
Please inspect with a dial gauge, ruler or feeler gauge whether the permissible displacement figures specified
in table 12 can be observed.
