  • Patent number: 8808130
    Abstract: A gear reduction assembly may include an input shaft, a first spur gear, and a second spur gear. The first and second spur gears may be coupled to one another. At least one of the first spur gear and the second spur gear may be associated with the input shaft such that the input shaft drives at least one of the first and second spur gears. The gear reduction assembly may further include a first internal gear engaged with the first spur gear, a second internal gear engaged with the second spur gear, and a hub associated with the first internal gear The first and second internal gears have a first number of teeth and a second number of teeth, respectively, and the first number of teeth differs from the second number of teeth by from one to five teeth. The gear reduction assembly may be included in a winch.

  • Patent number: 8720291
    Abstract: An automatic multi-speed gear system including an input axle, a first arm configured to couple with the input axle allowing for independent rotational movement of the input axle along the input axle axis, a first axle configured to couple with the first arm allowing for independent rotational movement of the first axle along a first axle axis, a second arm configured to couple with the first axle allowing for independent rotational movement of the first axle along the first axle axis, a second axle configured to couple with the second arm allowing for independent rotational movement of the second axle along a second axle axis, and an output axle. The first arm and the second arm are configured to move from a high-speed misalignment position to a low-speed alignment position where the second axle orbits the first axle.

  • Patent number: 8641570
    Abstract: Infinitely variable motion control (IVMC) provides motion control without any requirement for changing gears or use of a clutch. A spur gear transgear, defined as a system having an input, an output and a control, a variable pitch cam having an eccentric inner and outer cam assembly, a driver and a one-way clutch or ratchet bearing assembly may be used to form a cam controlled speed converter converting a given input to a variable or constant output speeds and further having direction control. All IVMC's, cam controlled IVMC, input compensated IVMC and pitch controlled IVMC may be utilized to form various embodiments of infinitely variable generators, transmissions and compressors/pumps.

  • Patent number: 8591372
    Abstract: An output-side swing arm is adapted to be swung about a swing axis thereof when the output-side swing arm is urged by a corresponding part of an input-side swing arm, which is driven by a force transmitted from an input shaft. An adjusting mechanism adjusts an amount of swing of the output-side swing arm by changing a location of a point of action of the input-side swing arm relative to the output-side swing arm in a radial direction of the swing axis of the input-side swing arm.

  • Patent number: 8449426
    Abstract: A continuously variable transmission includes a one-way clutch, a plurality of linking members, and a variable gear ratio mechanism. The one-way clutch includes an input shaft, a plurality of eccentric discs, a first crank member, a second crank member, an output member, an input member, and an engaging member. The input shaft is rotatable about an input center axial line under the rotational force. The plurality of eccentric discs is disposed around the input center axial line at equal intervals in a circumferential direction.

  • Patent number: 8388481
    Abstract: A system and method for providing a constant output from a variable flow input comprises a liquid flow energy input, for example, air or water for driving a constant speed generator. An inner and outer cam assembly is controlled by a control input to achieve varying eccentricity and control the output speed at an output shaft to be constant despite a varying rotational velocity input at an input shaft. A feedback control may be provided between one of the input shaft and the output shaft and the inner and outer cam assembly to maintain constant output by varying the eccentricity. The constant output may drive a constant speed generator having an infinitely variable torque generator. In this manner, a power grid may be provided with constant frequency alternating current at, for example, 50 Hz (Europe) or 60 Hz (USA).

  • Patent number: 6641499
    Abstract: A transmission has a gear system (34) which may be in the form of an orbit system (32, 35) or a planetary orbital spur system. The gear systems include a control gear (32) which is controlled to determine the drive ratio of the transmission. The control gear is controlled by a momentum control which includes a disc (23) and a slide (25) which carries a magnet (30) for selectivity allowing or preventing rotation of the disc (23) to in turn change the speed of rotation of the control gear (32). Alternatively, the momentum control can be formed from moveable masses which move radially outwardly relative to the control shad to change the speed of rotation of the control gear.
