Remaining competitive in today’s challenging business environment requires efficiency and productivity levels to remain high at all times. This means that reducing the time needed for maintenance or repair is a crucial part in achieving these objectives. The unique concept of the Reich Multi Mont drive coupling allows speedy replacement of the flexible transmission elements without the need to de-couple the mechanical drive train, eliminating the need for re-alignment.
The Multi Mont product range features in a long line of innovative drive couplings for mechanical power transmission applications developed by Reich Kupplungen GmbH. The Multi Mont Sella flexible jaw coupling is a clever and easily customised concept for connecting shafts within a drive train to transmit torque.
This pluggable design has been successfully proven over the years, with regular updates to maintain its ‘state of the art’ reputation. The range now covers a torque capacity from 40Nm to 1,000,000Nm. The main benefit of the Multi Mont Sella flexible jaw coupling is the ability to change its flexible transmission elements without the time consuming work required to move machinery and then re-align it afterwards. There is no need to uncouple the drive, as simply unbolting a retaining cap allows it to be slid 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 & 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 GmbH have 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 & 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.
