Hollow shaft and joint interior part connection arrangement, has external groove formed in area of teeth-free overturn, and axial safety units including snap ring provided in radial surface of interior part which points to shaft end

摘要

The arrangement (11) has a shaft (21) with outer shaft gear teeth (24) for torque introduction into a shaft end (22) and a joint interior part (31) with inner shaft gear teeth (34). The teeth are engaged with each other and form a torque proof connection between the shaft and the part. The teeth (24) extend up to an output shaft at a distance to an end of the teeth (34) such that an external groove (27) is formed in an area of a teeth-free overturn (25). Axial safety units have a snap ring (13) provided in a radial surface of the part which points to the end (22).
