  2. 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.

  3. 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 ...

  4. 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 ...

  5. Actuator - Wikipedia

    en.wikipedia.org/wiki/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. By rotating a wheel/axle (e.g. drum, gear, pulley or shaft) a linear member (e.g. cable, rack, chain or belt) moves. By moving the linear member, the wheel/axle rotates. [18]

  6. Gear - Wikipedia

    en.wikipedia.org/wiki/Gear

    Torque can be converted to linear force by meshing a rack with a round gear called a pinion: the pinion turns, while the rack moves in a straight line. Such a mechanism is used in the steering of automobiles to convert the rotation of the steering wheel into the left-to-right motion of the tie rod (s) that are attached to the front wheels.

  7. Rotary actuator - Wikipedia

    en.wikipedia.org/wiki/Rotary_actuator

    Hydraulic or pneumatic rotary actuator, using a rack and pinion. Both hydraulic and pneumatic power may be used to drive an actuator, usually the larger and more powerful types. As their internal construction is generally similar (in principle, if not in size) they are often considered together as fluid power actuators. [2]

  9. Backlash (engineering) - Wikipedia

    en.wikipedia.org/wiki/Backlash_(engineering)

    The linear sliding axes (machine slides) of machine tools are an example application. Most machine slides for many decades, and many even today, have been simple (but accurate) cast-iron linear bearing surfaces, such as a dovetail- or box-slide, with an Acme leadscrew drive. With just a simple nut, some backlash is inevitable.
