  2. Linear actuator - Wikipedia

    en.wikipedia.org/wiki/Linear_actuator

    Wheel and axle: Hoist, winch, rack and pinion, chain drive, belt drive, rigid chain and rigid belt actuators operate on the principle of the wheel and axle. A rotating wheel moves a cable, rack, chain or belt to produce linear motion. [1] Cam: Cam actuators function on a principle similar to that of the wedge, but provide relatively limited ...

  3. Chain drive - Wikipedia

    en.wikipedia.org/wiki/Chain_drive

    Drive shafts are another common method used to move mechanical power around that is sometimes evaluated in comparison to chain drive; in particular belt drive vs chain drive vs shaft drive is a key design decision for most motorcycles. Drive shafts tend to be tougher and more reliable than chain drive, but the bevel gears have far more friction ...

  4. Mechanical advantage - Wikipedia

    en.wikipedia.org/wiki/Mechanical_advantage

    For a toothed belt drive, the number of teeth on the sprocket can be used. For friction belt drives the pitch radius of the input and output pulleys must be used. The mechanical advantage of a pair of a chain drive or toothed belt drive with an input sprocket with N A teeth and the output sprocket has N B teeth is given by

  5. Rigid chain actuator - Wikipedia

    en.wikipedia.org/wiki/Rigid_chain_actuator

    Rigid chain actuators function as rack and pinion linear actuators that use articulated racks. Rigid chain actuators use limited-articulation chains, usually resembling a roller chain, that engage with pinions mounted on a drive shaft within a housing. The links of the actuating member, the “rigid chain”, are articulated in a manner that ...

    en.wikipedia.org/wiki/Motorcycle_testing_and...

    The amount of power lost due to friction in the transmission (primary drive, gearbox and final drive) depends on the details of the design and construction. Generalizing, a chain drive motorcycle may have some 5-20% less power at the rear wheel than at the crankshaft, while a shaft drive model may lose a little more than that due to greater ...

  7. Friction drive - Wikipedia

    Ixion engine on a Komet motorised bicycle, ca. 1902. This system is used, for example, to drive the spools in some tape recorders.In a typical configuration, one of the cylinders is the axle of an electric motor, say 1 mm in diameter, while the other is a disk with a hard rubber rim, say 50 mm in diameter, yielding a 1:50 mechanical advantage.

  9. Continuously variable transmission - Wikipedia

    en.wikipedia.org/wiki/Continuously_variable...

    When the output disk is adjusted to a position equal to its own radius, the resulting drive ratio is 1:1. The drive ratio can be set to infinity (i.e. a stationary output disk) by moving the output disk to the center of the input disk. The output direction can also be reversed by moving the output disk past the center of the input disk.
