摘要:
A method and apparatus for minimizing backlash and improving the efficiency of speed reduction mechanisms in which a series of rollers are equally spaced in a circle on a disk to perform operationally somewhat like an internal ring gear. Mounted for eccentric movement and simultaneously engaging each of the rollers is an orbital rotor having a perimeter defined by an epitrichoid curve with a numer of lobes equal to one less than the number of rollers. The rotor is mounted for free rotation on an eccentric keyed to a drive shaft. Rotation of the drive shaft causes the rotor to move orbitally and to rotate with a speed reduction equal to the reciprocal of the number of lobes on the rotor. A similar structure may serve as a second stage with a second orbital rotor driven by the first rotor and moved orbitally by the same eccentric. In carrying out the method of this invention, each of the rollers is individually adjusted to bring it into engagement with the rotor under controlled pressure and compliance. Each roller is mounted for controlled omnidirectional compliance and preloaded to provide an controlled pressure between each roller and the adjacent surface of the rotor. The outer surface of each roller is crowned to increase the efficiency and prevent binding that might be caused by angular deflection of the roller. Each roller is mounted on a shaft that is pressfitted into an eccentric bore in a mounting sleeve that is enlarged near the roller to provide for controlled deflection of the shaft as the sleeve is rotated in its mounting. Each roller is individually adjusted to produce a controlled preload pressure between the roller and the rotor.

A motion transforming mechanism comprises a rotation shaft (11) having a center axis (CA₁₁) and formed with at least three cranked shaft portions (11a, 11b and 11c) having respective eccentric axes (CA 11a , CA 11b and CA 11c ) in parallel relationship to one another and to the center axis (CA₁₁), the eccentric axes of the cranked shaft portions (11a, 11b and 11c) being displaced from and arranged equiangularly around the center axis (CA₁₁). The motion transforming mechanism further comprises a plate assembly (12) constituted by at least three rotation plates (13 to 15) having a plurality of teeth (13b, 14b and 15b) and formed with cranked through bores (13c, 14c and 15c), respectively. The cranked shaft portions (11a, 11b and 11) of the rotation shaft (11) are rotatably received in the cranked through bores (13c, 14c and 15c) of the rotation plates (13 to 15), respectively. The motion transforming mechanism further comprises an annular toothed rail (19) having a mid-circumferential plane (MP) perpendicularly intersected by the center axis (CA₁₁) of the rotation shaft (11) and having an inner surface configured to have a plurality of teeth (19b) held in mesh with the teeth (13b, 14b and 15b) of the rotation plates (13, 14 and 15). The rotational motion of the rotation shaft (11) causes each of the rotation plates (13 to 15) to be rotated with respect to the center axis (CA₁₁) of the rotation shaft (11) and being transformed into a relative curvilinear motion between the annular toothed rail (19) and the plate assembly (12).
摘要:
A mechanism for transmitting rotational motion from an input shaft (10) to an output shaft (11) includes a link (12) which is constrained to move about an orbital path, the input shaft (10) being coupled to the link (12) so that rotation thereof will drive the link (12) about its orbital path, and the output shaft (11) being coupled to the link (12) so that orbital motion of the link (12) will cause the output shaft (11) to rotate. One of the shafts (11) is coupled to the link (12) by means of a pair of interengaging components, one component (28, 29) being provided on the shaft (11) for rotation therewith and the other component (20, 21, 22) being pivotally mounted on the link (12), the pivotal axis of the component (20, 21, 22) moving in a circular path upon rotation of the link (12), the axis of said circular path coinciding with the axis of rotation of the link (12), a lever (25) being pivotally connected at one end to the component (20, 21, 22) mounted on the link (12) and at the other end to a pivot (26) isolated from movement of the link (12), so that upon movement of the link (12) about its orbital path an oscillatory rotation will be imposed on the component (20, 21, 22) mounted on the link (12) thus providing a sinusoidal variation in rotation of the shaft (11) relative to the link (12).

A rotation transmitter includes a worm shaft (2) having an hourglass-shaped portion at the center thereof, a plurality of metal balls (8) arranged in a row on a ball circulation path, a cylindrical housing (9) for rotatably accommodating the worm shaft therein, a worm wheel (3) inserted in an axial slot (10) in the housing and provided in the outer periphery thereof with ball fitting grooves (7) for receiving the balls, and holding means for holding the worm shaft within the housing so that the worm shaft is rotatable in a state of meshing with the worm wheel via the balls. A helical ball guide groove (5) is formed in the outer periphery of the hourglass-shaped portion of the worm shaft, and a circulation bore (6) penetrates the hourglass-shaped portion obliquely from one side to the other side thereof so that the opposite ends thereof communicate with the associated ends (5a, 5b) of the helical ball guide groove via tangentially curved guide holes (14). The ball circulation path is thus constituted by the guide groove and circulation bore.
