ROTEX® BTAN

0 - 12,500 Nm / torsionally flexible jaw coupling with brake drum

The torsionally flexible jaw coupling ROTEX BTAN is an elastomer coupling combined with a brake drum. ROTEX type BTAN is used as a holding brake, but also a a service brake.

The ROTEX jaw coupling with brake drum (drum brake) to be mounted to external drum brakes with double shoes. The brake drum is positioned on the driven side. For combinations with a brake drum please note the potentially resulting high circumferential speed - KTR recommends dynamic balancing with high-speed drives from 30 m/s.

Safety-relevant drives are preferably combined with hubs made of steel/GJS, applications with moderate demands can be combined with GJL hubs.

Features

each coupling type can be combined with various sizes of brake drums
following DIN 15431/15435
axial plug-in
damping vibrations
compensating for displacements (axial, radial, angular)

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).
