ABSTRACT:
The homokinetic joint has an inner ring and and an outer ring formed with axial track grooves so as to be opposite to each other, balls received in the track grooves, a cage mounted between the inner and outer rings and having pockets accommodating the respective balls, whereby torque is transmitted between the inner and outer rings through the balls so that the inner and outer rings will rotate at the same speed. The distance between said track grooves formed in the inner ring and those formed in the outer ring is determined so that the balls are fitted in the grooves between the ring and the inner ring with a predetermined interference, while leaving an axial clearance between the pockets of the cage and the balls. Thus, the balls can roll smoothly with little play in the direction of rotation.
