Screw-eccentric cam combination, has shaft including coded or profiled section that extends up to screw head, where one of eccentric cams has cutting with corresponding vaulting or sinuous line distribution

摘要

The combination has a screw with a screw head (20), and an eccentric cam (12) arranged at the head. A shaft (22) supports vaulting or sinuous line distribution, on which another eccentric cam (14) is attached by a counter vaulting or corresponding sinuous line distribution. The shaft runs over the vaulting or distribution in a thinner external thread (24), whose outer radius is smaller than the smallest distance of the vaulting or distribution. A coded or profiled section of the shaft extends up to the head, where the cam (12) has a cutting (30) with the corresponding vaulting or distribution.
