KWD HEK 120 Coupling

Operation Manual
KWN 32005 Edition B At the types 2200 and 2300 a twisting limitation consisting of stop segment 8 and stop
ring 9 is provided for between the highly flexible elements 6 and 7.
The flexible ring elements of the highly flexible couplings can be produced – depending
on requirement – in the following rubber qualities:
Rubber quality W
(soft)
Rubber quality M
(medium)
Rubber quality H
(high damping)
The letter indicating the rubber quality appears behind the coupling size; afterwards the
indication of the type is given, e.g.
HEK 200 M, type 1300 All details being missing in the general description of the standard for special types of
the series HEK are described and explained in a supplementary sheet and /or in the
general drawing.
2. Function The torque is transmitted -
at the types 1300/2300 from the coupling hub 1 via the highly flexible elements 6, 7,
and the intermediate flange 3 to the clutch hub 2
-
at the types 1200/2200 from the coupling hub 1 via the highly flexible elements 6, 7,
and the intermediate ring 10 to the companion flange 11.
In the process the flexible ring elements 6 and 7 are loaded in torsion. A special shaping
and a special material composition of the highly flexible elements enable a great torsion
angle.
