6.2 Finish bores
The following procedure has to be followed to
produce a finish bore in a coupling hub:
•
Clean and remove all preservatives from the
coupling hubs.
•
Mount the coupling hub in between the sur-
faces marked with
é
and carefully align the
hub according to the centering diameter ØD
and to the flange contact surface.
•
The values for d
1max
, d
2max
as listed in table 1
are valid for keyed connections according to
DIN 6885/1 and must not be exceeded.
•
Select the bore fit so that an interference fit
such as H7/m6 results when mating it with the
shaft tolerance.
•
Secure the hub with a setscrew, shaft end
plate or suitable interference fit against axial
movement on the shaft end.
Consult TSCHAN GmbH in case of other shaft-hub connections.
•
The stated maximum bore diameters are valid for keyed connec-
tions according to DIN 6885/1 and must not be exceeded.
•
If these values are exceeded, the coupling can break.
•
Flying off coupling fragments are a danger to life!
