【Abstract】 The rolling bearing planetary reducer with driving balls is the latest design of the reducers. One of its outstanding characters is that the rolling bearing is both supporting member and transmitting member. The structural scheme of the new reducer is given in this paper. Furthermore, the transmitting principle, the calculation of transmitting ratio, and the calculation criteria of the maximal transmission capacity are all considered. The deep groove ball or the angular contact radial ball bearing can be used as the driving rolling bearing E . Their diameters are selected from light to extra heavy with i =2～3. If a non-criterion rolling bearing is used as the driving rolling bearing with i ≤10. A maximum transmitted power of this planetary reducer is dependent on a product of a friction torque of the bearing E inner ring spacer and an angular speed W A of the shaft A . This planetary reducer can be used to transmit medium or low power. Because its transmisson efficiency is higher, the reducer can also be used as a speed increaser.更多还原
