The internal gear is a type of gear with tooth profiles distributed on the inner circular surface. It is often meshed with an external gear to form an internal meshing transmission. It has a compact structure, a large transmission ratio, high space utilization rate, smooth meshing and good coaxiality. It is mostly used in planetary gearboxes, reducers, automotive transmissions, etc., and is suitable for transmission scenarios with heavy loads, high precision and small size.
Internal gears provide numerous advantages in mechanical engineering due to their unique structural design and operational characteristics. Whether in automatic transmissions, robotics technology, or high-precision servo systems, internal gears deliver efficient, stable, and reliable performance.
