Types and Applications of Spur Gears
There are two main types of spur gears: external and internal. The teeth of the external gear are cut out on the outer surface of the cylinder.
There are two main types of spur gears: external and internal. The teeth of the external gear are cut out on the outer surface of the cylinder. The two external gears mesh together and rotate in opposite directions. In contrast, the teeth of an internal gear are cut out on the inner surface of a cylinder.
Spur gears are generally considered suitable for applications requiring speed reduction and torque multiplication, such as ball mills and crushing equipment. Despite the high noise levels, high-speed applications for spur gears include consumer appliances such as washing machines and blenders. Spur gears have a wide range of applications: they are used to increase or decrease the speed of an object, they can also be used to increase or decrease the torque or power of a specific object. Since spur gears transmit motion and force from one shaft to another in a mechanical structure, they are also suitable for washing machines, mixers, tumble dryers, construction machinery, fuel pumps, etc.
