DIN6 internal helical gear housing in high precision gears
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

power skiving internal ring gear for planetary gearbox
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 is 0.8 ,teeth :108
Material :42CrMo plus QT ,
Heat Treatment :Nitriding
Accuracy: DIN6

Helical ring gear housing for robotics gearbox
This helical ring gear housings was used in robotics gearboxes , Helical ring gears are commonly used in applications involving planetary gear drives and gear couplings. There are three main types of planetary gear mechanisms: planetary, sun and planet. Depending on the type and mode of shafts used as input and output, there are many changes in gear ratios and directions of rotation.
Material :42CrMo plus QT ,
Heat Treatment :Nitriding
Accuracy: DIN6

Internal Gear Used In Planetary Gearbox
Internal gear also often calls ring gears ,it’s mainly used in planetary gearboxes . 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. Internal gear can be machined by,shaping ,by broaching ,by skiving ,by grinding.
