摘要： This invention relates to a kind of split-power final reduction gear comprises a final driving casing (1), two driving pinions (2) and (4), a pair of split-power cylindrical gears (3) and (5), heavy-duty differential assembly (6) and a driven gear (7). Input power applies to either driving pinion (2) or (4), then half of the input power is shifted to the other driving pinion through split-power cylindrical gears (3) and (5). The driven gear (7) is supported on the differential assembly (6), and same number of teeth are machined in both sides of it. The driven gear engages with both driving pinions, concentrates the power from two transmission branches to itself and in tern transfers the power to differential assembly. With present invention, hub reductors can be eliminated while ground clearance were kept unreduced, thus the cost of driving axles is cut down, fuel consumption and noise are decreased.

A nutation reducer in this application includes: a case, two pairs of nutation gear pairs, each pair being disposed in the case and composed of a nutation gear and non-nutation gear in engagement, and the non-nutation gear being fixed in the case or integrated formed in the case; an output shaft, rotationally disposed in the case; two annular spring films, each nutation gear of the gear pair is connected to the output shaft through one annular spring film; a nutation generating mechanism disposed in the case, two nutation gear pairs being respectively disposed on both sides of the nutation generating mechanism. Power-split arrangement is applied in this application, symmetric layout of the nutation gear pairs is adopted. In this way, the working efficiency of the reducer is obviously improved, meanwhile the volume and weight of the reducer, and the heat generated in working process are reduced, and power density is improved.

摘要： A gear pair and nutation reducer are provided to solve such existing problems in prior art nutation reducers that they tends to be locally wore during long term operation due to rather short arc length of effective part on the tooth flank of the pin gear, and that the contact stress in tooth flanks is high due to great relative curvature between the contacted tooth pair, although much more tooth pairs can get into engagement at the same time. The gear pair is formed by a pin gear (400) and a non-instantaneous-pole enveloping gear (500) in meshing engagement with each other, the effective tooth surface of the pin gear (400) being constructed of an elliptical cone segment (b) that is outwardly convex, and the distance between the highest and lowest points on the elliptical cone segment (b) in the same cross-section gradually decreases inwardly along the generatrix of the reference cone of the pin gear. The disclosure uses the elliptical cone segment (b) as the effective tooth surface of the pin gear (400) meshing with the non-instantaneous-pole enveloping gear (500), resulted in increased effective width of the tooth surface and load capacity of the teeth, lowering the wear of the effective tooth surfaces.

摘要： A bearing cage assembly comprises multi-group rollers (2), each group has multiple rollers, and each roller is a barrel roller, multiple rollers are stacked together to form a group of rollers, and the end surfaces of each two adjacent rollers contact with each other. Multiple groups of pockets (11) are formed in the cage, and each group of pockets has multiple pockets. The pockets in any group are distributed along the circumference direction of the said cage, and a group of rollers is disposed in each pocket. Multi-group rollers can roll in circumferential direction of the cage. During the rolling process, a great number of contact points are distributed on the raceways, thus the load capacity of the bearing is improved, the friction resistance is low, suitable for the fields where high speed operation is necessary. A planar thrust bearing, a radial bearing and a conical radial-thrust bearing are provided.
