Planetary Gears

A planetary gearset, also referred to as epicyclic gearing, has three components; the sun gear, the planet gears' carrier and one or more planet gears, and the ring gear. With these three components, different gear ratios can be produced depending on which gear you use as input, which gear you use as output, and which gear is held still. The ratio of input rotation to output rotation is dependent upon the number of teeth in each gear, and on which gear is held stationary.The chief benefit of planetary gearing is that the input and output are in line. Many planetary gearboxes are attached to a motor to reduce the speed of the motor and create more power. Planetary gearing can be added in stages using a common ring gear with multiple suns and planets. Avon Gear makes custom planetary gear components and complete assemblies. They can be made from a wide variety of materials depending on the application. Contact Avon Gear today to learn more about our planetary gear capabilities.
