  • Patent number: 11181151
    Abstract: A transmission that suppresses a tilt of a slider in an axial direction and reduces a dimension of the slider in the axial direction for downsizing is provided. A transmission includes a fifth-speed driven gear disposed on a counter shaft, a fifth-speed driving gear that always meshes with the fifth-speed driven gear and disposed on a main shaft, and a first slider disposed on the counter shaft to be movable in the axial direction in accordance with a shift operation. The first slider includes first dog recesses. The fifth-speed driven gear includes fifth-speed dog projections configured to mesh with the first dog recesses. The fifth-speed driven gear includes a fifth-speed driven gear protrusion only on a location closer to a radially outer peripheral end thereof than the counter shaft. The fifth-speed driven gear protrusion protrudes in the axial direction so as to contact the first slider when the first slider falls in the axial direction.

  • Patent number: 11168775
    Abstract: In a unit-type strain wave gearing, a rotating-side member, which is constituted by a second internally toothed gear and an output shaft is supported, via a first sliding bearing and a second sliding bearing, on a fixed-side member so as to be capable of relative rotation, the fixed-side member being constituted by a unit housing and a first internally toothed gear. Sliding bearing surfaces of the first sliding bearing and sliding bearing surfaces of the second sliding bearing are defined by a conic surface having a central axis line as a center line. It is possible to realize a unit-type strain wave gearing which is advantageous in making smaller and more compact than when a roller bearing is used. It is also easier to adjust the gap between the sliding bearing surfaces because a radial sliding bearing having no function to adjust the radial gap is obviated.

  • Patent number: 11143283
    Abstract: A strain wave gearing has a wave generator which flexes an externally toothed gear in a radial direction to form meshing portions thereof with an internally toothed gear in positions that are separated along a circumferential direction of the externally toothed gear. When the wave generator rotates, the meshing portions move in the circumferential direction. Non-meshing regions are formed in part of the meshing portions along the tooth trace direction thereof. The non-meshing regions are those of a prescribed width including the support center of a wave bearing in the tooth trace direction. The concentration of stress in the tooth root of the externally toothed gear can be alleviated, and the tooth-root fatigue strength of the externally toothed gear can be increased.

  • Patent number: 11118668
    Abstract: A strain wave gearing wherein the outer circumferential surface of an outer ring of a wave generator is in contact with an inner-circumferential-surface portion of a flexible externally toothed gear, and a release groove, which is not in contact with the outer circumferential surface, is formed in the inner-circumferential-surface portion. The release groove is formed in a region containing a ball raceway groove. The groove depth of the release groove gradually increases from both sides of the groove in the groove width direction toward a deepest portion of the groove provided at an intermediate portion in the groove width direction. By providing the release groove, it is possible to smooth the distribution of pressing force of the wave generator acting on the externally toothed gear in the tooth-trace direction. In addition, the tooth root fatigue strength and the transmission torque capacity of the externally toothed gear can be improved.
