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
Versions available

- With horizontal axially split bolted
Flanges
- Spacer type
- Brake drum type
- Extended hubs type
- Cardan shaft type
Weight
The coupling is suitable for all kinds of coaxial drive systems, using nylon rod cross-sectional shear strength to transfer torque, transfer torque of 160 160000N m, working temperature 20 80C, simple structure, convenient maintenance, with cushioning and shock absorption performance and certain axial deflection compensation ability.
