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.
