Coupling improves uptimes

Easily customised for connecting shafts within a drive train to transmit torque, the pluggable design has been successfully proven over the years, with regular updates to ensure it remains ‘state of the art’. The range now covers a torque capacity from 40 to 1,000,000Nm.

There is no need to uncouple the drive, as simply unbolting a retaining cap allows it to slide out of the way, exposing the flexible transmission elements, which are then removed and replaced radially. This concept generates considerable savings in time over alternative product types, helping to maintain the highest levels of uptime and efficiency.

The Multi Mont Sella flexible jaw coupling standard range is made from Spheroid Graphite (SG) Iron for the hubs and flanges, with steel for the retaining cap. The use of SG iron with its greater elasticity gives a better and more robust coupling which is less susceptible to damage and also allows the incorporation off keyless clamping elements, either internal locking assemblies or external shrink discs. The keyless clamping method of locating a coupling hub on to a shaft offers many distinct advantages over traditional methods such as keyways, splines and thermal shrink fits.

A natural/synthetic rubber mix is used for the flexible transmission elements. Natural rubber is proven to be the best material for damping, so the Multi Mont Sella flexible jaw coupling can be used where torsional vibration is present. The standard flexible elements have temperature range of -40°C to 100°C, for higher temperatures silicone element with temperature range of -70°C to 120°C are available.

Reich Kupplungen has developed the Multi Mont Sella flexible jaw coupling into a versatile product with many variants as standard including shaft to shaft; shaft to flange; flange to flange; with brake drum or with brake disc versions, also a standard version with the very popular taper bush centre.

Designers and engineers have taken advantage of the unit’s adaptable design to easily combine the coupling with other mechanical power transmission products such as torque limiters, clutches, freewheels and fluid couplings to create bespoke drive solutions. Designers & engineers who have demanding applications requiring ATEX certification can now specify the new standard ATEX Multi Mont Sella flexible jaw coupling.

Innovations around the Multi Mont Sella flexible jaw coupling continue with the recent development of a high-speed version made from high-grade aluminium, which is capable of speeds up to 20000rpm.
