Planetary Reducers, Epicyclic gearing Reducers– Why is there a significant increase on Planetary Gear Motor usage? Why does customer like Planetary gear motor more and more? Why do they choose Planetary reducers to combine with dc gear motor, brushed, brushless, stepping, servo motor even the cost is a little higher than the other gearbox? Planetary reduction gear Reducer could work on high operating efficiency, easier mountings, offer high torque in a compact package, wide range of reduction ratio for wide applications. Especially it’s ideal for intermittent or continuous duty heavy situation. Dual roller bearings design, heat treatment of gear or shaft to increase the strength of gearbox, thicken the gear to let bearing capacity bigger. We do our best to meet customers’ critical request. We could offer a datasheet of straight speed-torque curve, with starting torque, speeds and current to let you know the motor’s peak efficiency with operating torque. You will find out the difference between our motor types and finally, the best choice will come out. The size of DORYOKU Planetary Gearbox range from 18mm to 80mm; gear ratios ranging from 4:1 to 11909:1, and continuous torque of up to 4,166 oz-in! Customized design welcome. DORYOKU can provide special shaft or flange version upon request. Gearbox design, Shaft and Flange shape can be made according to your requirement. Please contact us for more information.
