The internal gear has teeth on the inside of a cylinder. The teeth may be made either spur or helical. The teeth of an involute form internal gear have a concave shape rather than a convex shape.

Internal gears are generally more efficient since the sliding velocity along the profile is lower than for an equivalent external set because of the concave nature of the internal tooth profile its base is thicker than an equivalent external gear tooth (either spur or helical) The tooth strength of an equivalent external gear.

Internal Gears cannot be used where the number of teeth in the pinion is almost the same as that of the gear. When this occurs, the tips of the pinion teeth interface with the tip of the gear teeth. While the good guide is to maintain a ratio of 2:1 between the number of teeth on the internal gear and it’s mating pinion.

Use of Internal gear:

Generally, Internal Gears are used for the transmission of power. Internal Gears are gear teeth generated in the internal diameter.

We manufacturing Internal Gears with following specifications:

1. Diameter: 30mm to1000mm.
2. Module: up to 05 Module.
