A planetary gearset, also referred to as an epicyclic gear train, is made up by three components: the ring gear, the sun gear, and multiple planet gears. Different gear ratios can be converted easily by simply changing out the carrier and sun gears.

Application: As planetary gears are typically smaller than other types of gearboxes, they are used in applications where space is limited. They also can be found in most modern automatic transmissions in the automotive industry.

Elsewhere, they can be found in equipment such as augers and wind turbines, in-vehicle drive systems for helicopters and aircraft engines, etc.

Runsom produces made-to-order planetary gear components and completes assemblies. They can be made from a wide range of materials according to the desired application.
