4 Assembly
4.3 Assembly of the coupling
We recommend to inspect bores, shaft, keyway and feather key for dimensional accuracy

before assembly.
Heating the hubs lightly (approx. 80 °C) allows for an easier mounting on the shaft.
Please pay attention to the ignition risk in potentially explosive atmospheres!
Touching the heated hubs causes burns.
STOP Please wear safety gloves.
With the assembly please make sure that the distance dimension E (see table 1 and 4) is ob-
!
served to allow for axial clearance of the sleeve while being in operation.
Disregarding this advice may cause damage to the coupling.
With the assembly please make sure that the spline of the hub is fully covered by the internal
!
spline of the elastomer. (Please observe mounting dimensions L, L
Disregarding this advice may cause damage to the coupling.
 Applies with type HEW-ZS only (size 100 to G 125)!
Screw the flange hub (component 4.2) with the additional flange (component 4.1) at the tightening torques T
specified in table 9.

 Mount the hub, flange hub with additional flange or the coupling flange onto the shaft of the driving and driven
side.
 Shift the power packs in axial direction until the mounting dimension L, L
achieved.
 If the power packs have already been firmly assembled, shifting the hub, flange hub or the coupling flange or
coupling flange axially on the shafts allows for adjusting the mounting dimension.
 Fasten the hub, flange hub or coupling flange by tightening the setscrews DIN EN ISO 4029 with a cup point
(tightening torques see table 7).
 Valid for type HEW-ZS only!
Mount the hub spec. (component 2) in front of the intermediate shaft hub (component 3) and screw the com-
ponents at the tightening torques T
