Toothed shaft connection between drive shaft and hub - has teeth and tooth gaps in drive shaft gearing prismatic and hardened over entire length

摘要

The counter teeth (62) and counter teeth gaps (63) of the hub are also prismatic at least over the length (12) of the longitudinal gearing (61) which has toothed play but are not hardened over the adjoining play-free length (11). The hardened longitudinally toothed end (9) of the drive shaft is pressed into the non-hardened play-free part (11) of the longitudinal toothing (61) of the hub (6) with plastic deformation of their counter teeth (64). To make the connection the drive shaft and hub are first provided over the entire axial extension of the connection with the corresponding prismatic gearing (91,61) and then the gearing (61) of the hub is then compressed from the outer end side over a first part so that the counter tooth gaps of the hub become narrower than the drive shaft teeth. ADVANTAGE - Automated construction and long service life.
