Coupling system between shaft and hollow member with blind seat allowing decoupling without damage

摘要

Ring-shaped member (20) is displaceable on the shaft (10) and can be fastened to the hollow member (12a). A first shoulder area (22) on the shaft engages the ring-shaped member so that the shaft is locked in the seat (12) relative to the member in the axial direction. Fastenings are preferably screws (28) passing through openings (24) in the ring-shaped member into apertures (32) in the hollow member.
