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
é
and carefully align the coupling hub.
·
The indicated values in table 2 and 3 for ød
2max
and ød
6max
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!
