The Rubber Wedge Couplings are mechanical devices used in the transmission system of the Railway Industry. It has a wide range of applications in Metros, Freight wagons, High-speed passenger coaches etc. In any mechanical device, the coupling is a part that connects two revolving shafts. The purpose of this connection is to transmit power from one part of the machine that produces power and the other part that absorbs it. And the rubber drive coupling is the technical element that is used to transmit torque and power between shafts in a smooth and safe way while holding huge angular misalignment, vibration and shock in the system. Sujan Industries is the leading manufacturer of customized Rubber Wedge Couplings and exporting to the overseas railway industry.

Set-Up of Rubber Wedge Couplings

This element is attached with the gearbox hollow shaft and on the other side; it stays frictionally attached with the wheelset axle. The coupling includes a gearbox spider, an intermediate shaft and an axle spider. The rubber wedge packages on the verge are installed into the gaps between the arms of the spiders under the pretension because of the shape of the wedge and are fastened to the intermediate shaft. The gearbox spider is attached to the gearbox hollow shaft with the help of cross toothing and screws. And the axle spider is fixed with the wheelset axle with the help of a conical press fit.

Under driving or braking torque, the rubber wedges are exposed to pressure load only, which is the preferred load direction for rubber elements. In all other directions, the rubber is subjected partly or entirely to shear stress. The spring characteristic values in this direction are lesser than the direction of the main load.

Design Advantages of Rubber Wedge Couplings

  • In dynamic mode, the coupling design behaves as self-centering. No systemic imbalance force rises to the surface.  
  • The tractive torque is transmitted as flexible as possible 
  • As the rubber volume is relatively large, alongside the gearbox toothing, the function of the drive unit is very quiet. 

Technical Details of Rubber Wedge Couplings

The gearbox spider and the axle spider contain high-grade spheroidal cast iron. The middle shaft has premium-grade cast aluminium. The rubber wedge packages have an aluminium wedge with both side’s vulcanized rubber and aluminium in-between plates. At each end, there’s a U-shaped aluminium holding and guiding plates.
