ROTEX® SBAN jaw coupling with brake disk

Jaw coupling with brake disk

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

The ROTEX jaw coupling with brake disk for disk for brake calipers. Usually the brake disk is positioned on the driven side having the highest mass moment of inertia. For combinations with brake disks please note the potentially resulting high circumferential speed - KTR recommends dynamic balancing with high-speed drives from 30 m/s.

Fields of application of our torsionally flexible jaw coupling ROTEX SBAN with brake disk (disk for brake caliper):

This combination of coupling and brake disk is used wherever holding brakes or service brakes are required, e. g. on conveyor belts, generators, turbine drives, industrial fans, cranes, hoists, etc. 

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

Couplings and brakes by KTR:

The customer benefits from being supplied by one single source with the option to develop the brake (KTR-STOP and EMB-STOP) as well. Our brakes are available hydraulically (KTR-STOP) and electromechanically activated (EMB-STOP).

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 enable 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 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.

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 material by the colours orange (92 Shore A), purple (98 Shore A) and light green (64 Shore D).

The previous polyurethane spiders in the colours yellow, red and natural white with green marking of teeth continue to be available on request.
