Geneva Drive, Maltese Wheel |
An intermittent driving mechanism in which pins or rollers fixed to the primary wheel ride along a groove in the follower making the follower move intermittently. Contrary to cam-driven mechanisms, the Geneva drive has little design flexibility and a discontinuous acceleration at the start and stop ends. | |
Grinding | Cams are usually heat treated and quenched after which the surface of the cams are ground to attain a high degree of precision. |
