1)Descriptions of Helical Gear
By means of cutting, casting, forging and other processes, raw materials are processed into gears with spiral-shaped teeth,
which are called helical gears.
2)Advantages of Helical Gear
a) Process maturity: Turning processing is a common method for manufacturing helical gears, including hobbing and broaching, etc.
The process is mature, with high processing accuracy, and can meet the requirements of different precision grades.
b) High production efficiency: With the development of numerical control technology, the manufacturing of helical gears has achieved automation
and high-precision processing, significantly improving production efficiency, and ensuring stable product quality.
3)Applications of Helical Gear
This is applicable to all kinds of mechanical manufacturing industries. Whether it is single-piece or small-batch production
or large-scale industrial production, it can meet the requirements through appropriate manufacturing processes to ensure the normal operation
of the mechanical transmission system.
