INTERNAL GEARS

.INTERNAL GEARS

RoHS Compliance

Internal gears are the ones with the teeth formed on the inner surface of a cylinder or cone. Internal gears mesh with spur gears. There are two types of tooth shape, one being parallel and the other one with a helix in respect to the axis. However gears with teeth parallel to the axis have higher demand.

Planetary gear mechanism
The most popular application for internal gears is usage for planetary gear trains or gear reducers composed of a carrier, several spur gears, called planet gears and a sun gear in the center, rotating inside an internal gear.
