Jan 18, 2022 · A pulley works by changing the direction of the applied force that is manifested at the object. The wheel rotates about its axle when the rope is pulled from one end and the object is raised above the ground. The other end is either fixed or attached to the object.
A steel pinion (σ0 = 137.9 × 10 6 N/m 2) rotates an iron gear (σ 0 = 102.88 × 10 6 N/m 2) and transmits a power of 20 kW. The pinion operates at n1= 2000 rpm, and the transmission ratio is 4 to 1 (external gearing). Both gears are full-depth involute gears and have a pressure angle of 20°.

Jun 6, 2024 · Pinion bearings are specialized bearings that support pinion shafts, enabling smooth rotational movement. They reduce friction between moving parts, ensuring efficient power transmission within mechanical systems.
A rack and pinion is a type of linear actuator that comprises a circular gear (the pinion) engaging a linear gear (the rack), which operates to translate rotational motion into linear motion. A rack and pinion drive can use both straight and helical gears. Driving the pinion into rotation causes the rack to be driven linearly.
Rack and pinion, mechanical device consisting of a bar of rectangular cross section (the rack), having teeth on one side that mesh with teeth on a small gear (the pinion). The pinion may have straight teeth, as in the figure, or helical (twisted) teeth that mesh with teeth on the rack that are.
