108-5619: Sun Gear

The sun gear serves as an input and driver of the set. In planetary gearing also known as epicyclic gearing, a center gear is called sun gear. The sun gear is located at the center and transmits torque to the planet gears which are typically mounted on a moveable carrier. The sun gear is driven, and the planet gears rotate the outer ring gear. The wheels can be mounted over the housing of the gearbox. Attributes: • High torque density, operational efficiency and durability. • Manufactured using special, and in some cases proprietary, heat treat processed including case carburizing, nitriding, and induction hardening. • Relative to its size and are designed with reusability. Applications: The sun gear is used in automatic transmission and also used in differentials of machines and also in mechanical engines.
