Abstract
A method for producing an internal or external part of a torque-transmitting opposed track joint, such as a fixed constant velocity ball joint, in which approximately axially parallel extending track bases of the joint tracks have curvatures which deviate in their axial course from the curvatures of the ball contact lines. The method is characterized in that in a first step a perform with approximately axially parallel extending grooves having lateral flanks is produced, and in a second step the perform is formed into a final joint part whereby the lateral flanks of the grooves are just partially formed to achieve the ball contact lines.
Claims10
A method for producing an internal or external part of an opposed track joint, said method comprising:
- producing a preform having grooves with groove bases and lateral flanks, wherein said groove bases extend approximately axially parallel;
- thereafter producing a final joint part from said preform by forming the grooves of said preform into tracks having track bases, which extend approximately axially parallel, and ball contact lines,
- wherein:
- the ball contact lines are produced by partially forming and partially maintaining the lateral flanks of the grooves, and
- the approximately axially parallel extending track bases are produced by partially forming and partially maintaining said groove bases.
