Variable motion control devices and methods of use. The devices and methods relate to providing an output, such as a rotational shaft output (6), transmitted from a rotational shaft input (1), with the output varying based on a control input (50). The devices and methods are used, for example, to provide a variable output for use with a compressor, power take off, or transmission or differential application. To provide the variable output, the devices and methods include use of mechanical component systems, such as spur gear planetary systems, ring gear planetary systems, bevel gear arrangements, or combinations of such features. The control input is implemented, for example, by arrangements of bindably meshed gears, tension between pulleys joined by belts or similar arrangements of sprockets and chains, use of magnetic clutches, hydraulic or pneumatic controls, or braking devices.

A rotor controlled CVT comprising: input and output shafts (28,44), an elongated cam-shaped rotor (12) which is uniformly and linearly tapered over its length and is engaged for rotation with the input shaft, a plurality of cam follower units (54) which are located in structure about and are reciprocated by the rotor and include rollers (56) having treads which bear and rotate in circumferential paths on the rotor surface, angular velocity extraction devices (38) which are each engageable and partially rotated by a cam follower, means (14) for causing the extraction devices to collectively produce an output velocity at the output shaft, means for causing relative movement between the rotor and cam followers to vary the ratio of rotation between the input and output shafts, and means for keeping the roller treads in contact with the roller surface. The roller treads are in line contact with the rotor surface.

Variable speed drive to be connected to a rotating driving shaft (5) and to a rotating driven shaft (6) and characterized in that it includes at least two angled bearings (7, 7'), means for controlling the orientation of the axis (13, 13') of each angled bearing (7, 7') adapted so that said axes are offset from one another, and transmission means (9, 9', 11, 11') adapted so that in each phase of the movement at least one of the angled bearings (7, 7') engages and at least one of the bearings (7, 7') does not engage. The invention is also characterized in that the orientation controlling means are adapted to alter the slant of all the angled bearings (7, 7') on the basis of a signal for controlling the variation in the variable speed drive ratio.

A variable speed gear drive includes multiple gears (11, 12, 61, 62) forming a transmission device for variable speed output and direction from a constant input source. The multiple gears are so arranged that the control of the output is determined by a selective incremental control input relative the constant input source. By means of an adjustable camming and drive assembly (26-30) connected to an input drive shaft (13) and coupled to the gears, the gears utilise variable orbital paths to determine variable output.

A device for driving, in steps of adjustable extent, the hose winding drum of automatic irrigation sprinklers in general comprises a turbine (10) driven by the actual irrigation water and having on its shaft a first crank (15) to which there is connected a first connecting rod (16), the big end of which is compelled to move reciprocatingly along a substantially rectilinear path of variable direction, and is itself connected to the big end of a second connecting rod (18) connected to a second crank (20) which is longer than the first crank and which by way of free-wheel device drives a sprocket (23) from which the drive motion for the drum (5) derives.
摘要:
New equipment for continuously variable transmission, essentially composed by a disc with variable inclination (I), articulated by means of automatic servo-mechanism (C), positioned in the driver axis (A); the inclined disc system activates an oscillatory ring, also called pivot (D), by means of two opposed bearings (B) fixed in the pivot; the pivot activates two alternative elements of opposed power transmission, called rod (E); the force transmitted by the rods is applied to an arm of opposing levers, called balancer (F), with a turn radius originating in the center line of a transversal axis (M) positioned in the center of the transmission; in one side the transversal axis is installed in the interior of a semi-axis (P) and transmits continuous rotation in only one direction by means of a sprag bearing and on the other side symmetrically; in the internal side of the set, there are external conical helical gears (K), integral to the semi-axis; the exit-axis, or moved (H), is the own axis of a sprocket (G), positioned symmetrically between both gears, which center line is axial to the entrance axis of the transmission, being able to have a lateral exit of 90° or inclined exit in relation to the entrance axis; the sprocket receives the torque from one of the gears when the driver axis turns.

In one embodiment, a transmission includes: a wobbler having an outer periphery tiltable with respect to a wobble axis of rotation; a set of freewheeling gears disposed in a fixed relationship with respect to one another, each gear having a gear axis of rotation about which the gear may rotate different from the gear axis of rotation of each of the other gears; one or both of the wobbler and the set of gears rotatable with respect to one another about the wobble axis of rotation; and each gear operatively connected to the wobbler simultaneously with the other gears at a place on the periphery of the wobbler different from the place at which each of the other gears is operatively connected to the wobbler such that each gear rotates on its axis of rotation as the wobbler wobbles or as the wobbler induces a wobble in another part.
