Vitesses sikloidal
Cycloidal gearboxes or reducers contain four fundamental components: a high-speed input shaft, a single 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 followers in the housing. Cylindrical cam followers become teeth on the inner gear, and the number of cam fans exceeds the number of cam lobes. The second track of substance cam lobes engages with cam supporters on the result shaft and transforms the cam’s eccentric rotation into concentric rotation of the output shaft, thus increasing torque and reducing velocity.
Compound cycloidal gearboxes offer ratios ranging from as low as 10:1 to 300:1 without stacking levels, as in regular 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 quantity for followers or rollers in the slow velocity output shaft (flange).
There are several commercial variations of cycloidal reducers. And unlike planetary gearboxes where variations are based on gear geometry, heat therapy, and finishing procedures, cycloidal variations share simple design concepts but generate cycloidal motion in different ways.
Planèt bwat
Planetary gearboxes are made up of three fundamental force-transmitting elements: a sun gear, three or more satellite or planet gears, and an interior ring gear. In a typical gearbox, the sun gear attaches to the input shaft, which is linked to the servomotor. Sunlight gear transmits engine rotation to the satellites which, subsequently, rotate in the stationary ring gear. The ring equipment is section of the gearbox casing. Satellite gears rotate on rigid shafts connected to the earth carrier and cause the planet carrier to rotate and, thus, turn the output shaft. The gearbox provides output shaft higher torque and lower rpm.
Planetary gearboxes generally have one or two-gear stages for reduction ratios which range from 3:1 to 100:1. A third stage could be added for actually higher ratios, nonetheless it is not common.
The ratio of a planetary gearbox is calculated using the following formula:
where nring = the number of teeth in the inner ring equipment and nsun = the amount of teeth in the pinion (input) gear.
Great things about cycloidal gearboxes
