Spur gaer

A spur gear is a cylindrical gear with straight, parallel teeth mounted on a shaft. It transmits motion and power between parallel shafts with high efficiency. Manufactured from hardened steel, cast iron, or brass, precision cutting ensures smooth engagement. Common applications include industrial machinery, automotive transmissions, clocks, and pumps. Spur gears offer simple construction, compact design, and no axial thrust. They provide reliable speed reduction or torque multiplication, though they may produce audible noise at high speeds. Proper lubrication ensures long service life. Ideal for low-to-medium speed power transmission applications.
