Short Description:

DIN6 is the accuracy of the internal helical gear . Usually we have two ways to meet high accuracy .

1) Hobbing + grinding for internal gear

2) Power skiving for internal gear

However for small internal helical gear ,hobbing is not easy to process ,so normally we would do power skiving to meet the high accuracy and also high efficiency .For big internal helical gear ,we will use hobbing plus grinding method . After power skiving or grinding ,middle carton steel like 42CrMo will do nitriding to increase the hardness and resistance

The ring gear refers to the internal gear on the same axis as the planet carrier in the planetary gear transmission. It is a key component in the transmission system used to convey the transmission function. It is composed of a flange half-coupling with external teeth and an inner gear ring with the same number of teeth. It is mainly used to start the motor transmission system.

The machining process of the ring gear includes the following steps:

1. Preliminary forging forming: select commercially available steel, reserve a margin according to the drawing requirements, and preliminary forging forming

2. Polishing treatment: polishing and polishing the preliminarily formed workpiece in step A to remove surface burrs and impurity particles;

3. Use shapping ,power skiving ,vertical lathe, drilling and other equipment for rough and finish machining to meet the design requirements;

4. Soft nitriding treatment: the workpiece obtained in step D is subjected to soft nitriding treatment

5. Shot blasting and anti-rust treatment.

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 .
