Spur Gear
Spur gears are one of the most popular types of precision cylindrical gears. These gears feature a simple design of straight, parallel teeth positioned around the circumference of a cylinder body with a central bore that fits over a shaft.
The most common gears are spur gears and are used in series for large gear reductions. The teeth on spur gears are straight and are mounted in parallel on different shafts. Spur gears are used in washing machines, screwdrivers, windup alarm clocks, and other devices.
Spur gears are used for a wide range of speed ratios in a variety of mechanical applications, such as clocks, electric screwdrivers, pumps, watering systems, material handling equipment, power plant machinery, and clothes washing and drying machines.
Spur gears are more efficient compared to helical gears with the same size. They are quite reliable and offer constant velocity. Spur gears are also considered a member of positive transmission because they don’t have any slippage.
