Abstract
A flexible coupling for disposition between two rotating shafts to reduce transmission of vibration or to increase the torque and speed range of the coupling for a given level of vibration transmission comprises input and output members connectible to driving and driven shafts and interconnected by a spacer via coupling elements which are flexible in the plane of rotation by centrifugal force and by torque transmitted through the coupling, such that, over a range of speeds and torques the spacer is relatively rotatable to at least one member. A secondary coupling is also disclosed to render radially rigid a primary coupling comprising input and output members and coupling elements. The secondary coupling may comprise a bearing or a plain bearing, a multiple bearing or a cross links flexural pivot.
