This subsurface increases in size during further tensioning. The spur gearing sections are designed such that, viewed in the radial direction, the first and second teeth initially come only into contact with one another on the radially inward side during axial tensioning and, as tensioning increases, also come into contact with one another on the radially outward side, for which purpose a substructure of the sleeve section and/or of the outer joint part having the teeth is designed to be more easily deformable in a radially inward region than in a region lying radially further outward. | 01-22-2015 |
