Cam drive, particularly for printing press

摘要

The drive has a periodically rotating driven member. The driving (1) and driven (2) members are in separate bearings, (Ao,Bo) on a frame. The driving member has three closed smooth cam tracks (K1,K2,K3), in each of which a roller (R1,R2,R3) of the driven member works. One of these rollers is a double one, with first and second parts on a common bolt (5.3). The parts are spring-loaded apart at right angles to the bolt axis. The member bearings are inside the path described by the contact points between the cam tracks and rollers as the driving member rotates. The working direction of the springs can be adjustable.
