Internal ring gear traditional process adopts tooth shaping or broaching process for production. In recent years, the use of broaching plus hobbing and other processes to process the ring gear has also achieved good economic benefits. Power skiving, also known as shaping combines hobbing , is a continuous cutting process for gears. This technology integrates two processes of gear hobbing and gear shaping. From a technical perspective, it is a processing process between "formed teeth" and "gear hobbing", which can realize rapid processing of gears with strict requirements on tightness.Depending on the part requirements, the skiving machine can be built on a vertical shaft base or a horizontal shaft base. The compact design, the thermal stability of the machine and the high precision of the hydraulics guarantee the machining quality, resulting in a very low surface roughness of the final part. Depending on the application, the hobbing machine can be combined with skiving and face turning, or combined with hobbing, drilling, milling or straight helical gears, making it the most efficient alternative to gears.

The production efficiency of the gear skiving process is higher than that of gear hobbing or gear shaping. Especially in the context of the continuous increase in the application frequency of internal gears in the domestic production of transmission devices, strong gear skiving processing internal gear rings has higher production efficiency and higher efficiency than gear shaping. precision.
