Short Description:

The helical internal ring gear was produced by power skiving craft ,For small module internal ring gear we often suggest to do power skiving instead of broaching plus grinding ,since power skiving is more stable and also has high Efficiency ,it takes 2-3 minutes for one gear ,accuracy could be ISO5-6 before heat treat and ISO6 after heat treatment .

Module:0.45

Teeth :108

Material :42CrMo plus QT ,

Heat Treatment :Nitriding

Accuracy: DIN6

Product details

Power skiving internal ring gear for planetary gearbox reducer ,The 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.

Manufacturing Plant

We have three production lines for internal gears also calls ring gears like spur ring gears and helical ring gears ,usually spur ring gears will be done by our broaching machines to meet ISO8-9 accuracy ,if broaching plus grinding which could meet ISO5-6 accuracy ,however helical ring gears will be done by our power skiving machines ,which could meet ISO5-6 accuracy well ,which was more regular for small helical ring gears .
