Cycloidal gearbox

Cycloidal gearboxes
Cycloidal gearboxes or reducers consist of four basic components: a high-speed input shaft, an individual or substance cycloidal cam, cam followers or rollers, and a slow-speed output shaft. The insight shaft attaches to an eccentric drive member that induces eccentric rotation of the cycloidal cam. In compound reducers, the first tabs on the cycloidal cam lobes engages cam supporters in the casing. Cylindrical cam followers act as teeth on the inner gear, and the amount of cam fans exceeds the number of cam lobes. The next track of compound cam lobes engages with cam followers on the result shaft and transforms the cam’s eccentric rotation into concentric rotation of the output shaft, thus raising torque and reducing acceleration.

Compound cycloidal gearboxes offer ratios ranging from only 10:1 to 300:1 without stacking stages, as in standard planetary gearboxes. The gearbox’s compound reduction and will be calculated using:

where nhsg = the amount of followers or rollers in the fixed housing and nops = the number for followers or rollers in the slow speed output shaft (flange).

There are many commercial Cycloidal gearbox variations of cycloidal reducers. And unlike planetary gearboxes where variations derive from gear geometry, heat treatment, and finishing procedures, cycloidal variations share fundamental design principles but generate cycloidal movement in different ways.
Planetary gearboxes
Planetary gearboxes are made of three fundamental force-transmitting elements: a sun gear, three or even more satellite or planet gears, and an internal ring gear. In an average gearbox, the sun equipment attaches to the input shaft, which is connected to the servomotor. The sun gear transmits engine rotation to the satellites which, in turn, rotate inside the stationary ring equipment. The ring equipment is area of the gearbox housing. Satellite gears rotate on rigid shafts linked to the earth carrier and cause the earth carrier to rotate and, thus, turn the output shaft. The gearbox gives the output shaft higher torque and lower rpm.
