We recommend to inspect bores, shaft, keyway and feather key for dimensional accuracy
before assembly.
Heating the coupling flanges lightly (approx. 80 °C) allows for an easier mounting on the
shaft.
STOP
Touching the heated coupling flanges causes burns.
Please wear safety gloves.
!
With the assembly please make sure that the distance dimension E or E
1
(see table 1) is
observed to allow for axial clearance of the spider when in operation.
Disregarding this advice may cause damage to the coupling.
Mount the coupling flanges (component 4Nv and 4Nx) onto the shaft of driving and driven side. The coupling
flange (component 4Nx) for the assembly of the brake disk (component 15Nx) has to be mounted to the shaft
end which has the bigger mass moment of inertia (see illustration 4).
The internal sides of the coupling flanges (component 4Nv and 4Nx) must be flush with the front sides of the
shafts (see illustration 4).
Shift the power packs in axial direction until the distance dimension E
1
is achieved (see illustration 4).
Fasten the coupling flanges (component 4Nv and 4Nx) by tightening the setscrews DIN EN ISO 4029 with a
cup point (tightening torque see table 4) or an end plate.
Mount the brake disk (component 15Nx) onto the centering shoulder of the coupling flange (component 4Nx)
(see illustration 5).
Stick the driving flanges (component 3Na) and the spider (component 2) together (see illustration 6).
Install the components sticked together between the coupling flanges (component 4Nv and 4Nx) (see
illustration 7) and hand-tighten the components with the cap screws (component 1a and 1b) first.
Tighten the screws at the tightening torques T
A
specified in table 1 by means of a suitable torque key.
Center the spider (component 2) between the driving flanges (component 3Na) and check the dimensions E
and s (see illustration 1).
