摘要

Device for producing by metal forming or primary shaping spiral running tracks on inner and outer parts of homocinetic joints in VL style with crossed running tracks comprises a contour tool (1) with a negative contour of the running tracks and consisting of a first tool part (5) with negative contours (6) for right-hand running tracks and a second tool part (7) with negative contours (8) for left-hand running tracks, which slide together to form the contour tool. To eject a manufactured homocinetic joint inner part or outer part, the two tool parts are axially pulled apart without rotation, at the same time releasing the homocinetic joint inner part or outer part into a rotating motion. An independent claim is also included for the production by metal forming or primary shaping of spiral running tracks on inner and outer parts of homocinetic joints in VL style with crossed running tracks.
