Mounting Hint
STOP
D A N G E R !
The maximum permissible bore diameters d
1max
and
d
2max
(see ROTEX
®
catalogue) must not be exceeded. If
these figures are disregarded, the coupling may tear.
Rotating parts may cause serious danger.
•
Hub bores machined by the customer have to observe
concentric running or axial running, respectively (see
picture 4).
•
Please make absolutely sure to observe the figures for
d
1max
and d
2max
.
•
Carefully align the hubs when the finish bore is brought
in.
•
Please provide for a setscrew or an end plate for the
axial fastening of the hubs.

Assembly of the hubs
F
A T T E N T I O N !
We recommend to check bores, shaft, keyway and feather key for dimensional accuracy
before assembly.
Heating the hubs slightly (approx. 80° C) allows for an easier installation onto the shaft.
STOP
D A N G E R !
Touching the heated hubs may cause burns.
We would recommend to wear safety gloves.
Assembly of the coupling
!
C A U T I O N !
For the assembly please make sure that the distance dimension E (table 2) is kept to
ensure that the spider can be moved axially when in operation.
Disregarding this hint may cause damage on the coupling.
•
Assemble the FN hub with the brake drum / brake disk. Tighten the screws with a suitable torque wrench to
the tightening torques T
A
(see picture 5).
F
A T T E N T I O N !
Before tightening the screws please put Loctite 243 on the threads.
•
Assemble the hub and the FN hub with the brake drum / brake disk onto the shaft of the driving side and the
driven side. Put the FN hub onto the shaft end where the bigger mass moment of inertia becomes effective.
The max. braking torque must not be bigger than the max. torque (T
kmax
) of the coupling (see picture 6).
•
Secure the hubs by fastening the grub screws DIN 916 with splined cup point or by an end plate.
•
Install the spider inside the cams of the hub (see picture 7).
•
Push the machines to be connected together until the distance dimension E is achieved.
