A sprocket is a wheel with cog-type buckle sprocket, which is used to mesh with a block with an accurate pitch on a link or cable. Sprockets are widely used in mechanical transmission in chemical, textile machinery, escalators, wood processing, three-dimensional parking garages, agricultural machinery, food processing, instrumentation, petroleum and other industries.
As a new gear product, the sprocket has a high transmission speed. In its specific application process, due to its high speed advantage, the noise generated is very small, which is also conducive to achieving a good processing environment. In its application, the sprocket not only has a high installation accuracy, but also has an ideal machining accuracy, which saves a lot of trouble for future maintenance work. Moreover, the advantages of the compact structure of the sprocket make it have a larger transmission ratio, and its own service life is relatively high.

It is a high-tech enterprise specializing in the production of standard sprockets (ANSI, DIN, JIS).

After more than ten years of steady development and technological accumulation, it has become one of China's most experienced sprocket manufacturers.

Gear oil has many incomparable characteristics. If it can effectively prevent rust, this is what other additives do not have.

According to the geometrical relationship, the intersection line between the normal plane and the indexing cylindrical surface at a point on the helical cylindrical gear tooth line is an ellipse.　　

The corresponding machines and cutters are hobbing machine and hobbing cutter, gear shaper and gear shaper cutter, horizontal milling machine and gear milling cutter
