KTR ROTEX SH COUPLING

Coupling with split hubs / SPLIT hubs Rotex SH KTR

The torsionally flexible jaw coupling ROTEX SH is an elastomer coupling with split hubs / SPLIT hubs (half shell coupling) easy to service and is characterized by easy assembly and disassembly.

This design is also referred to as drop-our center design coupling, half shell coupling, clamping coupling, coupling with split hubs or elastomer coupling with split clamping hub.

Elastomer coupling with split hubs / SPLIT hubs:

The hubs of the half shell coupling ROTEX SH have been split into two halves precisely, mechanically and reliably by "cracking". A rough surface with positive-locking connection ensuring an accurate fit of the two halves is generated. The contoured, rough cracked surfaces ensure ideal centering of the hub halves. The split hubs allow to assemble and disassemble the elastomer coupling radially via four screws without displacing the adjacent power packs. This makes the elastomer coupling with split clamping hub particularly easy to assemble and service.

Benefits of couplings with split hubs SH Rotex:

Versions with half shells such as the torsionally flexible half shell coupling ROTEX SH have been part of our product range for decades.
Please find more detailed information about benefits of half-shell couplings in our article "Couplings with split hubs: benefits and applications".

ROTEX® torsionally flexible jaw couplings Rotex SH are elastomer couplings characterized by a compact design.

In spite of low weights and mass moments of inertia of the elastomer couplings they are able to transmit high torques. The compact shaft couplings are characterized by a long service life and sound operating characteristics generated by allover machining.

Thanks to the elastomer (elastomer spider) between the coupling hubs of the jaw couplings shocks respectively torsional vibrations in the drive train are damped. The high temperature-resistant spider material T-PUR® (elastomer) is available in various degrees of hardness. The torsionally flexible ROTEX couplings are used in almost every range of general machinery and plant engineering.

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

Jaw couplings ensure torsional vibration-damping power transmission and absorb shocks generated by machines with irregular operation.

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 resist significantly higher loads.

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

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