Grid Type Resilient Couplings

ROMA make RESIFLEX Resilient Coupling essentially consists of a GRID SPRING connecting two hubs mounted on driving and driven shafts.
The grooves are cut axially on the outer surface of the hubs and the grid spring runs through the grooves to from a series of resilient bridges. The grooves are flared outwards to give the spring-members long flexible spans at normal loads. The un-flared portion of the groove in the central area provides increasing support to the spring-members under overload condition. The stiffness of the spring (and therefore of the coupling) depends on the unsupported length of each flexible span and varies with every variation in torque. As a result the coupling stiffness changes at every instant during a vibration cycle. A powerful detuning action is produced which continuously alters the torsional vibration frequency and prevents a build up of resonance in the system.

The driving and driven hubs are generally keyed to the connected shafts or shrunk fitted and are totally enclosed in a shell filled with grease or oil depending on the speed of operation. The shells are flanged and bolted either in horizontal plane or vertical plane

Advantages for Resilient Couplings

•High Torque / Weight Ratio
•Low Weight
•Low Moment Of Inertia values
•Provides Resiliency in the system
against shocks, surge loads
•Low Maintenance
•Can absorb various misalignments viz.
Angular, Parallel, Combined Angular-
Parallel including End-Float of shafts
