An epicycloid planet gear cam that converts rotational movement of a driveshaft into linear movement of an output device is disclosed. An epicycloid planet gear is assembled inside a stationary housing with an internal stationary ring gear. A driveshaft eccentric is connected to a driveshaft. The driveshaft eccentric rotates freely in a mounting hole of the epicycloid planet gear. When the driveshaft rotates, the driveshaft eccentric engages the epicycloid planet gear against the stationary ring gear and causes the epicycloid planet gear to rotate. A cam follower pin attached to an output device is held against a cam track of the epicycloid planet gear. As the epicycloid planet gear rotates, the raised cam track height or the slotted cam track distance from the center of the epicycloid planet gear causes the cam follower pin to move up, down, in, or out thereby moving the output device. |
