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

ROMAFLEX Brake Drum couplings serve dual purpose of flexible coupling as well as providing brakedrum for mounting brake within the same space. The coupling can be used with all kinds of brakes with shoes; Electromagnetic, Thruster, Band etc. The material of the couplings is high grade Cast Iron, Power transmitted from one half to other through steel pins precision machined passing through specially bonded rubber bushes. The elastic properties of rubber bushes enable the coupling to take shock loads, torsional vibrations and misalignment. The units can be operated in either direction require no lubrication and are unaffected by water, dust and atmospheric conditions. NOTE: - Non-standard brakedrum size also available. Kindly refer to us for details. Advantages for Flexible Pin Bush Couplings - Robust Design - High Flywheel Moment values - Easily replaceable flexible elements i.e. rubber bushes - Provides Resiliency in the system against shocks, surge loads - Low Maintenance - Can absorb various misalignments viz.
