Abstract: A composite planetary speed reduction device (1), wherein gears (11), (12), and (13) and rollers (21), (22), and (23) forming a planetary gear speed reduction mechanism (10) and a planetary roller speed reduction mechanism (20) are integrally rotated around a common rotating center axis, respectively. The radius of the sun roller (21) is larger by Δr1 than the radius r1 of the working pitch circle of the sun gear (11), the radius r21 of the working pitch circle of the planetary gear (12) meshing with the sun gear (11) and the radius r23 of the working pitch circle of the planetary gear (12) meshing with an internal gear (13) are different from each other, and the radius of the planetary roller (22) is smaller by Δr1 than the radius r21 of the working pitch circle of the planetary gear (12). Thus, a slippage ratio s1 between the sun roller (21) and the planetary roller (22) and a slippage ratio s2 between the planetary roller (22) and the ring roller (23) are made equal to each other, and a large output torque can be provided from the planetary roller speed reduction mechanism (20).

Abstract: A planetary gear includes a middle planetary gear part, a disc part on one side of the planetary gear part having a radius smaller than a radius of the tooth root circle of the planetary gear part and another disc part on another side of the planetary gear part having a radius bigger than a radius of a tooth edge circle of the planetary gear part. An internal gear includes a middle internal gear part, an inner cylindrical part on one side of the internal gear having a radius smaller than a radius of a tooth edge circle of the internal gear part and another inner cylindrical part on another side of the internal gear having a radius bigger than a radius of a tooth root circle of the internal gear part. The planetary smaller disc parts can rollingly engage the smaller inner cylindrical part of the internal gear. The planetary bigger disc parts can rollingly engage the bigger inner cylindrical part of the internal gear. The planetary gear part and two disc parts are unified in a body. Unification of the planetary gear reduces the cost of manufacturing and assembling and additionally, alleviates noise generation from the operating assembly.

Abstract: An improved support ring (50) is disclosed for supporting a plurality of planetary gear sets (20) which are driven by a centrally disposed input shaft (12) having a sun gear (16) attached thereto in which the planetary gear sets are subject to radially inward loads. The support ring (50) includes an inner ring (52) and an outer ring (57). The inner ring (52) has a bore (54) which is disposed around the input shaft (12) and an outside surface (56) and the outer ring (57) has a bore (58) with a diameter greater than the diameter of the outside surface of the inner ring. The outside surface (60) of the outer ring rotatably supports the planetary gear sets (20). Preferably, the outer ring (57) has a spring rate which is less than the inner ring (52) to readily permit absorption of radial loads when the outer ring does not contact the inner ring. A retaining ring (62) may be provided to maintain a fixed axial relationship between the inner (52) and outer rings (57).

Abstract: A gear assembly for high-speed transmission between either two parallel shafts or two intersecting shafts comprising two meshing gears, one mounted to a drive shaft and the other mounted to a driven shaft, each of the gears having coaxially disposed first and second toothed portions which differ from each other in that the teeth of the first toothed portion are cut at a first inclination angle and the teeth of the second toothed portion are cut at a second inclination angle different from the first inclination angle. One of the meshing gears is fixed to its shaft so as to be non-displaceable axially, while the other is mounted so as to be axially displaceable with respect to the fixed gear. Preloading means engaging the movable gear are provided for applying an axially directed load to the movable floating gear thereby urging the floating gear against the fixed gear so as to eliminate the free angular displacement of the gears with respect to each other within backlash and to preclude tooth disengagement under axial forces which are imposed on the floating gear by external peripheral loads.
Abstract translation: 一种用于在两个平行轴或两个交叉轴之间进行高速传动的齿轮组件，包括两个啮合齿轮，一个安装到驱动轴上，另一个安装在从动轴上，每个齿轮具有同轴设置的第一和第二齿部， 彼此不同的是，第一齿形部分的齿以第一倾斜角切割，并且第二齿形部分的齿以不同于第一倾斜角的第二倾斜角度被切割。 啮合齿轮中的一个被固定到其轴上以便不可轴向移动，而另一个啮合齿轮安装成可相对于固定齿轮轴向移动。 提供接合可移动齿轮的预加载装置，用于向可移动浮动齿轮施加轴向定向的载荷，从而将浮动齿轮推靠在固定齿轮上，以消除齿轮相对于齿隙内的自由角位移并防止齿 在通过外部外围载荷施加在浮动齿轮上的轴向力下脱离接合。
