Homokinetic joint comprises outer and inner rings whose respective internal and external surfaces are provided with track grooves between which balls are interposed and held by cage

摘要

The fixed type of homokinetic joint comprises an outer ring (25) whose internal spherical surface (21) has circumferential equidistant track grooves (22) extending axially towards the open end (23). An inner ring (28) has track grooves (27) in its spherical external surface (26). A certain number of balls (29) are interposed between the track grooves to transmit a torque are held by a cage (30) interposed between the spherical surfaces. The bottoms of the track grooves are cone shaped with a diameter expanded linearly towards the open end.
