1)Descriptions of Internal Gear
Internal gears are internal gears that need to be processed through methods such as hobbing, broaching or wire cutting.
They require high precision from both the tools and the machine tools.
2)Features of Internal Gear
a) The processing of internal gears is more difficult than that of external gears. Special tools are required to avoid interference.
b) Hardness and precision are usually enhanced through processes such as quenching and gear grinding.
3)Advantages of Internal Gear
a) High precision option: Through gear grinding technology, it can achieve IT5-IT6 level of accuracy, meeting the requirements of precise transmission.
b) High material utilization rate: The internal gear structure can reduce material waste and is suitable for mass production.
