Coupling shiftable at standstill

The torsionally flexible jaw coupling ROTEX SD is an elastomer coupling shiftable at standstill (shiftable coupling).

The shiftable ROTEX coupling type SD enables easy disconnection and connection of the driving and driven side with standstill of the plant.

Please note with shiftable coupling ROTEX SD:
Shiftable linkage also available with locking pins, lock device and retrieval of shifting position via sensors.

Features

jaw coupling shiftable at standstill / shiftable coupling
easy disconnection resp. connection of driving and driven machines with standstill of the plant
existing shiftable hub can be combined with slip ring and shiftable linkage
pilot bored shifting hubs must be set to the necessary shifting force after final machining
complete shifting device consists of split slip ring made of red brass, shifting fork, shifting shaft, shifting lever, eye-type bearing

Properties of torsionally flexible jaw couplings:

ROTEX shaft couplings consist of two hubs (aluminium or steel) and a spider (elastomer ring / cam ring) made of T-PUR®. The different degrees of hardness of the T-PUR® spider allow to adjust the level of damping and torsional stiffness of the elastomer coupling.

ROTEX couplings require few mounting space and thus allow for easy assembly/disassembly. The numerous types provide for maximum flexibility and meet with the different mounting requirements through various types of hubs.

Function of torsionally flexible jaw couplings:

Jaw couplings ensure torsional vibration-damping power transmission absorbing shocks generated by irregularly operating machines. In contrast to flexible couplings the connecting elements of which are subjected to bending and therefore to earlier wear, the flexible teeth of ROTEX® couplings (elastomers) are subjected to compressive stress only. The benefit of the elastomer coupling thus is to withstand significantly higher loads.

The elastomers deform with load and high speeds. Sufficient expansion space must be provided.

All sizes of ROTEX jaw couplings have a maximum torsion angle of 5°. They can be mounted both horizontally and vertically.

Material of torsionally flexible jaw couplings:

Our elastomer material T-PUR® is resistant to higher temperatures and has a considerably longer service life than common polyurethanes. From a visual point of view we marked the T-PUR® (elastomer) material by the colours orange (92 Shore A), purple (98 Shore A) and light green (64 Shore D).
