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. Recirculating ball - Wikipedia

   A diagram of a recirculating ball mechanism. Recirculating ball, also known as recirculating ball and nut or worm and sector, is a steering mechanism commonly found in older automobiles, off-road vehicles, and some trucks.

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

   Pneumatic actuator operating a valve through a rack-and-pinion mechanism. [7] A pneumatic actuator is similar to a hydraulic one but uses a gas (usually air) instead of a liquid. [8] [9] Compared to hydraulic actuators, pneumatic ones are less complicated because they do not need pipes for the return and recycling of the working fluid. On the ...

6. Rack railway - Wikipedia

   en.wikipedia.org/wiki/Rack_railway

   The Pilatus Railway is the steepest rack railway in the world, with a maximum gradient of 48% and an average gradient of 35%. Functioning of the rack and pinion on the Strub system. A rack railway (also rack-and-pinion railway, cog railway, or cogwheel railway) is a steep grade railway with a toothed rack rail, usually between the running rails.

7. Nilgiri Mountain Railway X class - Wikipedia
