The helical internal gear is a transmission component that combines the inner gear ring with the bevel teeth. The tooth direction has a helical angle, and during meshing, the tooth surfaces gradually come into contact. The mainly advantage is smooth transmission, low impact, and low noise, as well as strong load-bearing capacity and high precision. During of Processing it is often employed high precision techniques like scraping. It is not only suitable for planetary transmission structures, but is also more widely used in heavy-duty and high-precision transmission systems, such as reducers, wind power equipment, construction machinery, and automotive gearboxes, etc.
Helical internal gears mesh with external spiral gears to transmit power through tangential contact. During the rotation process, the design of the tooth profile ensures that the contact points are continuous, thus distributing the load smoothly and improving both transmission efficiency and stability.
