DRIVE FOR PLANNING MACHINE Russian patent published in 1997 - IPC

FIELD: mechanical engineering. SUBSTANCE: drive has crank 1, connecting rod 2, rocker 3 fixed to cam 4, and pusher 5 shifted with respect to the axis of rotation of cam 4 and connected to lever system 6 connected to slide 8 of the machine via pivot 9. The cam mechanism provides a negative angle of pressing that is equal to a friction angle between the working surface of the cam and roller of the pusher. Rotation of the crank of the connecting rod mechanism is converted into reverse-rotation (rocking) motion of rocker 3 and cam 4 that sets pusher 5 and, by way of lever system 6, slide 8 of the sleeve in reciprocation. EFFECT: improved design. 1 dwg
