Gear is a kind of mechanical component with teeth on the rim, which can continuously mesh to transmit motion and power. It is also a kind of mechanical part with teeth that can mesh with each other. The diameter of big gear is twice that of small gear. Gears are generally divided into teeth, slots, end face, normal surface, top circle, root circle, base circle and dividing circle.

HCVAC coating technology is an environmental protection technology, which can maximize the performance and reliability of large components. The resultant vacuum produces a very hard, wear-resistant part surface. Ensure high corrosion resistance, thermal stability and first-class friction performance. The resultant vacuum prevents micro pitting, high root strength and side loading. Due to the low processing temperature, there is little or no warpage in the assembly, which improves the sliding performance and reduces noise generation. No hard fine processing is required. Do not use toxic gases or chemicals. In addition, Huicheng vacuum is an excellent substitute for hard chromium electroplating.
