ROTEX® ZR

0 - 1,920 Nm / torsionally flexible half shell coupling with intermediate shaft

The torsionally flexible jaw coupling ROTEX ZR is an half shell coupling (coupling with split hub) with intermediate shaft for bridging large shaft distances.

Couplings with split hubs are also referred to as drop-out center design couplings, half-shell couplings, clamping coupling or elastomer couplings with split clamping hubs.

The intermediate shaft coupling ROTEX ZR allows for bridging large shaft distances. Its half shell clamping hubs allow for radial assembly/disassembly (drop-out center design coupling). Due to its double-cardanic arrangement the intermediate shaft coupling is able to offset large displacements.

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).
