Abstract
A constant velocity universal joint for coupling two shafts and for transmitting rotation between the shafts and enabling, independently, transmission of axial thrust between the shafts and/or slight angular displacements of the shafts relative to their axially aligned position. The constant velocity joint comprises two stub shafts adapted to be fixed to the shafts. One of the stub shafts having a cup-shaped end portion with an inwardly extending flange at its open end for mounting a socket member of a ball and socket joint whose toroidal ball member is mounted near the end of the other stub shaft. A first cylindrical sleeve is joined to the cup-shaped end portion of the flange and has an internally toothed gear at its free end meshing with radial clearance with an externally toothed gear at one end of a second cylindrical sleeve coaxial of the first cylindrical sleeve. An internally toothed gear at the other end of the second sleeve meshes with radial clearance with an externally toothed gear on the other stub shaft. The joint is of constant velocity operation.
