  3. Beier variable-ratio gear - Wikipedia

    en.wikipedia.org/wiki/Beier_variable-ratio_gear

    The Beier variable-ratio gear or Beier variator is a mechanical drive offering a continuously variable gear ratio between input and output. The gear relies on the inter-meshing of a number of thin disks. By varying their separation, the effective radius of one disk varies, thus changing the overall gear ratio.

  4. Rack and pinion - Wikipedia

    en.wikipedia.org/wiki/Rack_and_pinion

    A rack and pinion has roughly the same purpose as a worm gear with a rack replacing the gear, in that both convert torque to linear force. However the rack and pinion generally provides higher linear speed — since a full turn of the pinion displaces the rack by an amount equal to the pinion's pitch circle whereas a full rotation of the worm screw only displaces the rack by one tooth width.

    Transmission internals for a 2009 Volkswagen Golf. A transmission (also called a gearbox) is a mechanical device which uses a gear set—two or more gears working together—to change the speed, direction of rotation, or torque multiplication/reduction in a machine.

    [Vex] does not necessarily need to be connected to the common lead of the stator star windings. Simple two-synchro system. A synchro (also known as selsyn and by other brand names) is, in effect, a transformer whose primary-to-secondary coupling may be varied by physically changing the relative orientation of the two windings.

    Verification is intended to check that a product, service, or system meets a set of design specifications. [6] [7] In the development phase, verification procedures involve performing special tests to model or simulate a portion, or the entirety, of a product, service, or system, then performing a review or analysis of the modeling results.

  9. Overdrive (mechanics) - Wikipedia

    en.wikipedia.org/wiki/Overdrive_(mechanics)

    This is especially important because the differential gears are bathed in heavy oil and seldom provided with any cooling besides air blowing over the housing. The impetus is to minimize overdrive use and provide a higher ratio first gear, which means more gears between the first and the last to keep the engine at its most efficient speed.
