Device for isolating torque fluctuations

John Allport (Inventor)

Research output: Patent

Abstract

The present invention relates to a device for isolating torque fluctuations of a rotary drive shaft. The device comprises a first member (2) for connection to the drive shaft, a second member (3) for connection to a driven member and an intermediate member (21) interposed between the first and second members. The intermediate member comprises a radially outer ring (22) connected to the first member, a radially inner ring (24) connected to the second member and at least one resilient rolling element (32) in a cavity between the inner and outer rings. The cavity is defined by alignment of at least one pair of recesses (26, 29), one recess being on the radially inner surface of the outer ring and the other recess being on the outer surface of the inner ring, each recess having a ramped surface.; Relative rotation of the first and second members causes relative rotation of the inner and outer rings so that the rolling element rotates and compresses.
