THREE-LINK INVERSE GLOBOIDAL CAM MECHANISM

Click to enlargeClick to enlarge Description

Rocker arm 1 oscillates about fixed axis A and is the driver. It carries tapered roller 4 which rolls and slides along helical groove a of cam 2. The convex globoidal surface of cam 2 is generated by the revolution of a circular arc of radius R about axis B-B. Cam 2 rotates about fixed axis B-B. Transmission of motion from driver 1 to cam 2 is possible only if groove a has a sufficiently large helix angle. During one full cycle of motion, cam 2 makes one revolution.
