A universal joint comprises an inner member 14 with a part-spherical surface 18 engaging the inner cylindrical surface 20 of an outer sleeve member 10, the member 14 having a transverse groove 22 receiving a pair of axially mounted balls 24 also engaging parallel longitudinal grooves 26 in the outer member 10. The diameter of the balls 24 is preferably equal to the radius of the spherical surface 18. In modifications, Figs. 3 and 4 (not shown), the members 10, 14 are urged apart by a Belleville or coil spring (30), (40), separation being prevented by tapering the open end portion (21) of the surface 20 to spherical or conical form.</p> |
