Spur Gear

A spur gear is a type of toothed wheel that meshes with another gear, known as the mating gear, in order to transmit power or motion between two rotating shafts. The teeth on each gear engage and disengage as they rotate, transferring torque from one shaft to the other. Spur gears are commonly used in various mechanical devices such as clocks, watches, and machinery due to their simplicity and ease of manufacture.
