Cam drive with periodically circulating drive member for printing machines

摘要

The cam drive comprises a support, a drive (1) and a driven member (2), with the drive member consisting of flat cam bodies. The driven member contains cam rollers (R) meshing with the cam bodies. The support points (Ao) of the drive member and those (Bo) of the driven member lie in their projection on a plane through the drive member. The plane is located within cam trains (X) formed by the contact points of the cam contours (D) of the drive member with the cam rollers of the driven members, generated by the drive member rotation.
