7.2 Finished borehole
For the completion of the finished borehole in a coupling hub, pay attention to following
procedure:
Clean the coupling hub of preservatives.
Tighten the coupling hub to the faces labelled with
and carefully align the coupling hub.
The indicated values in table 1 for ød
1max
and ød
2max
are valid for a parallel key connection
according to DIN 6885/1 and must not be exceeded.
Choose the borehole fit so that during the union with the shaft tolerance a wringing fit
and/or an interference fit as for example at H7/m6 is carried out.
Provide a setscrew for axial securing on the hub back above the parallel key slot.
In the case of other shaft hub connections consultation with
RINGFEDER POWER
TRANSMISSION
is necessary.
The maximum indicated borehole diameters are valid for a parallel
key connection according to DIN 6885/1 and must not be exceeded.
In the case of transgression of these values the coupling can
sever.
Through flying away fragments danger exists!
