摘要： A clutch assembly includes an inner race, an outer race and a plurality of roller elements positioned radially therebetween. The clutch assembly also includes a cage assembly, a seal and a retaining ring. The cage assembly includes a skeleton coupled to a spring ring having a plurality of radially extending guides arranged to circumferentially space apart each roller element in alignment with cam surfaces formed on the outer race. The guides are resiliently deformable to allow concurrent engagement of each roller element with both the inner and outer races. The seal engages an inner surface of the outer race and an outer surface of the inner race, and is positioned axially outboard of the roller elements. The retaining ring is positioned within ring grooves formed on each of the inner and outer races to restrict movement of the cage.

摘要： A change-gear transmission having an input shaft, a main shaft having at least one main shaft gear, a plurality of countershafts spanning between the input shaft and main shaft gear, and gear synchronizers between selectable gears. The bore of main shaft gears have a minimal radial clearance fit with its mating parts to prevent gear synchronizer wear, while the meshing between the input shaft gears and countershaft gears is equally distributed using a means to equalize the torque transfer between countershafts. The countershafts are rotatably supported and displace axially between bearing or bushing supports, while the meshed gears comprise a helical gear tooth arrangement to create axial load on the countershaft if excessive and uneven load is sensed in one countershaft over another. This presents a new and unique countershaft meshing design that allows multiple countershafts to achieve equal load sharing while permitting gear synchronizers use on the main shaft.
摘要翻译：具有输入轴的变速齿轮传动装置，具有至少一个主轴齿轮的主轴，跨越输入轴和主轴齿轮之间的多个副轴以及可选齿轮之间的齿轮同步器。主轴齿轮的孔与其配合部件具有最小的径向间隙配合，以防止齿轮同步器磨损，而输入轴齿轮和中间轴齿轮之间的啮合通过均衡分配，以均衡中间轴之间的扭矩传递。中间轴可旋转地支撑并在轴承或衬套支撑件之间轴向移动，而啮合齿轮包括斜齿轮齿配置，以在一个中间轴超过另一个中轴感测到过大且不均匀的负载时，在中间轴上产生轴向载荷。这提供了一种新的独特的中间轴啮合设计，允许多个中间轴实现相等的负载分担，同时允许在主轴上使用齿轮同步器。
