摘要： A power transmission unit that can prevent unintentional disengagement of a clutch. A first set of teeth formed on an outer circumferential surface of a first rotary member is engaged with a third set of teeth formed on an inner circumferential surface of a second rotary member. A second set of teeth formed on an inner circumferential surface of the first rotary member is meshed with a fourth set of teeth formed on an outer circumferential surface of a third rotary member. A center of engagement between the first set of teeth and the third set of teeth is situated at a point withdrawn from a center of engagement between the second set of teeth and the fourth set of teeth in the direction to disengage the first set of teeth from the third set of teeth.

摘要： Infinitely variable motion control (IVMC) using Transgear gear assemblies provides rotary motion control without any requirement for connecting or disconnecting gear meshes or use of a clutch. A bevel, miter, ring or spur gear Transgear gear assembly may be defined as a gear assembly having three or four of variables, input, output and control, assigned in a manner so as to provide, for example, one of accumulation of inputs and direction control. A four variable Transgear gear assembly may be one of a spur gear Transgear gear assembly having an additional ring gear surrounding a set of planetary gears or a bevel gear Transgear gear assembly having a double bevel gear, an outer bevel gear and a bevel gear meshing to the outer bevel gear sleeve surrounding an inner beveled gear and comprising three orthogonal carrier shafts. Rather than two sets of three variable Transgear gear assemblies connected in series or in parallel, a four variable Transgear gear assembly may provide, for example, a direction control function with just one gear assembly with two of the four variables assignable as control variables.

摘要： A transmission apparatus includes an input shaft; an output shaft; a ring gear having internal ring gear teeth and having a ring gear central axis; a ring gear constraining structure constraining the ring gear to move translationally along a substantially circular path about the input shaft rotational axis without rotating about its own central axis relative to the apparatus; a mechanism for continuously changing the distance between the ring gear central axis and the input shaft rotational axis; a pinion gear having a diameter smaller than the inner diameter of the ring gear and retained with the ring gear so that its rotational axis is parallel with the ring gear central axis; and held in engagement with the ring gear teeth by a pinion gear constraining structure rotationally connected to an apparatus output shaft; where each time the input shaft rotates one revolution, the ring gear constraint structure moves the ring gear one revolution translationally along the circular path around the input shaft rotational axis, and the distance between the input shaft rotational axis and the ring gear central axis defines the diameter of the circular path over which the pinion gear travels during a single input shaft revolution, and thus defines the distance over which the pinion gear rolls for each revolution.

摘要： A driving hub (6) connected to a first shaft (3) rotatably carries primary planet wheels (10) meshing with first (11) and second (12) sun wheels in coaxial relation. The first sun wheel (11) is fastened to a helical crown gear (16) meshing with auxiliary planet wheels (18) rotatably linked to the second sun wheel (12). Eccentrically projecting from the auxiliary planet wheels are respective interconnecting elements (22) guided in a trochoidal rolling track (23) formed in a guide member (24) fastened to a second shaft (5). Each auxiliary planet wheel (18) is driven by a piston (28) engaged in a pressurization chamber (29) formed in the second sun wheel (12). A fluid supplying circuit (30-35) sends oil under pressure into the pressurization chambers (29) in order to transmit axial thrusts to the auxiliary planet wheels (18), which thrusts, by effect of the helical toothings, produce balanced forces interacting with a motive power so as to transmit motion from the first (3) to the second (5) shaft.

摘要： A bifurcated variable ratio drive transmission employs a pair of series connected differential gear stages. In a fist stage, torque flow from the engine output shaft is bifurcated into major and minor flow branches; in the second stage, the branches are combined. An engine output shaft drives an input ring gear of the first stage with the ring gear engaging a plurality of stepped planet gears. The planet gears in turn, drive both a sun gear of the first stage and a transfer ring gear. A major portion of torque flow is transmitted to the second stage through the transfer ring gear while a minor portion of torque flow passes from the sun gear of the first stage to the sun gear of the second stage. The transfer ring gear is fixed to a carrier to which are mounted pairs of radially spaced interengaged planet gears. Torque flow from the sun gear is amplified through the second stage planet gear pairs and combined with torque flow from the second stage carrier to drive the second stage ring gear which is connected to an output shaft.

摘要： The drive comprises a drive motor (1), two differentials (2, 2'), two worm drives (6, 6'), two servomotors (10, 10'), as well as two control units (9, 9'). The drive motor (1) is connected to one input shaft (3, 3') each, the worm gears (8, 8') are each connected to another input shaft (4, 4') of the differentials (2, 2'), and the worms (7, 7') are connected to output shafts (19, 19') of the servomotors (10, 10'). The driving shafts (5, 5') of the differentials (2, 2') are coupled with one another so that they rotate in opposite directions. The control units (9, 9') control the servomotors (10, 10') so that at constant speed of the drive motor (1) the sum of speeds of the output shafts (19, 19') is constant. Due to this design, the driving shaft (5) is able to rotate in both directions of rotation at constant direction of rotation and constant direction of the drive torque acting on the drive motor, and the driving torque is able to act in both directions. The second servomotor (10') and, if need be, the second worm drive (6') may also be replaced with an additional differential.
