ABSTRACT:
This invention relates to an improved torsionally resilient coupling such as a flexible coupling, damper, gear-wheel or the like connector of the type comprising two concentric members each provided with co-operating grooves to accommodate solid cylindrical blocks of resilient material such as rubber or synthetic rubber-like material of any required hardness between the concentric members for the purpose of transmitting torque and providing the desired degree of torsional deflection and stiffness for any particular application. In such an arrangement the block cavities formed by co-operating grooves in the outer and inner concentric members, are closed by end plates and have a central circular portion in contact with the cylindrical elastic block and developing at each end into tangential straight flanks of variable angularity which come into contact with the block only under torque load conditions, the blocks being subjected to radial deformation only as their length is equal to that of the cavity into which their diameter is a light driving fit.
