Driving And Driven Gears On Angularly Related Axes Patents (Class 476/26)
  • Patent number: 7207918
    Abstract: A mechanical continuously variable transmission in which the power roller is in “line contact” with the counter roller instead of conventional “pinpoint contact”. By utilizing line contact of the power roller and the counter roller, the pressure force between the metal components of a mechanical continuously variable transmission can be reduced. In addition, the line contact also reduces extra energy for maintaining the operation thereof. The configuration of the roll surface of the power roller, which is rotated by a rotation axle connected to an input axle, is formed into a partial configuration of a sphere. A plurality of counter rollers, which are in line contact with the power roller having said roll surface, are arranged in a circle by a disk. Each counter roller is formed with a concave roll surface corresponding to the partial configuration of the sphere on the surface thereof. The counter rollers are driven to rotate by the rotation of the power roller in contact therewith.

  • Patent number: 7096782
    Abstract: A driving apparatus in a printing press includes a plate cylinder driven by a printing press motor, an inking device drive-coupled to the plate cylinder, and a driving connecting/disconnecting mechanism. The mechanism connects and disconnects transmission of driving from the plate cylinder to the inking device, and includes first and second gears which are engageable with each other, supported rotatably, and constantly drive-coupled to one and the remaining one, respectively, of the plate cylinder and inking device. The second gear has a second engaging portion engageable with a plurality of first engaging portions of the first gear which have the same shape and are equidistantly arranged in a rotational direction of the first gear. When the first and second engaging portions engage, the plate cylinder and inking device are drive-coupled; when they are disengaged, they are disconnected.

  • Patent number: 6350317
    Abstract: A linear drive assembly for moving a body associated with processing a substrate is disclosed. The linear drive assembly includes a first gear and a second gear, which is operatively engaged with the first gear. The linear drive assembly further includes a positioning member having a first portion and a second portion. The first portion is movably coupled to the second gear in a linear direction, and the second portion is fixed to a component associated with processing a substrate.

  • Patent number: 5784870
    Abstract: A mower deck lift mechanism which includes a friction disk selectively pivotable into engagement with first and second pulleys of a double pulley jacksheave. A linkage coupled between the friction disk and the deck raises the mower deck when the friction disk engages and rotates with the first pulley, and lowers the deck when the friction disk engages and rotates with the second pulley. Neutral return mechanisms are provided for returning the friction disk to a neutral position when the operator releases a control and when the deck approaches its extreme raised or lowered positions. A cutting height preset mechanism is also provided.

  • Patent number: 5407399
    Abstract: A variable ratio friction transmission is described in which one element is a straight sided cone and the other a roller or wheel. The two are in frictional engagement. The roller or wheel moves over an element of the cone to change the speed ratio, and at all times stays parallel to itself and moves along a straight line axis. This axis passes through the apex of the cone at all times, but the cone is tilted about its apex to contact the roller or wheel as the ratio is changed.
