ROTEX® AH

0 - 12,500 Nm / torsionally flexible coupling with split hubs

The torsionally flexible jaw coupling ROTEX AH is an elastomer coupling with split hubs (half shell coupling). This design is also referred to as drop-out center design coupling, half shell coupling, clamping coupling, coupling with split hubs or elastomer coupling with split clamping hub.

The hubs of the ROTEX elastomer coupling type A-H are split. Easy radial asssembly/disassembly of the half shell coupling can be made by tightening and unscrewing four screws only. The version is available both with and without feather keyway.

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®(elastomer). 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 and offset shocks generated by irregularly operating machines.

In contrast to flexible couplings the connecting elements of which are stressed on 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).
