Abstract
A flexure coupling includes a backing plate and an adjacent hub, the backing plate being adapted to be mounted to a first machine member and the hub being adapted to be mounted to a second machine member. The hub is supported on the backing plate by a plurality of equiangularly positioned radial springs that permit compliant torsional movement of the hub relative to the backing plate. The springs prevent relative axial or longitudinal translational movement between the hub and backing plate, as well as relative radial movement. Substitution of the flexure coupling for conventional bearings eliminates the problem of false brinelling that results from vibration of stationary bearings.
