Abstract
A constant velocity ratio universal joint, suitable for high speed low angle use, comprises outer and inner joint members (10,11) with engaging part-spherical surfaces (12,13) and arcuate ball-receiving grooves (14,15) diverging towards an end of the outer joint member closed by a closure member (17) with balls (16) held in the grooves by an element (31) and support member (32) which is pivoted on the closure member, and a spring (36) acting between the element (31) and support member (32) so that the balls are urged as far as possible into the grooves to take up clearances and maintain stability of the joint, particularly under no-torque conditions.
