Proper surface treatment of heavy-duty gear parts can reduce friction and wear. The surface treatment methods of gears include grinding, sandblasting, heat treatment, coating, chemical treatment, and photolithography. These treatment methods aim to improve the surface quality of gears, enhance their wear resistance, hardness, corrosion resistance, and reduce friction coefficient.
For example, grinding can remove impurities and burrs from the surface of gears, improving their accuracy and smoothness; Heat treatment can change the microstructure of gears, improve their hardness and wear resistance; Coating treatment can apply a layer of metal or non-metal coating on the surface of gears to increase surface hardness, wear resistance, and corrosion resistance; Chemical treatments, such as acid washing and electrolytic polishing, can remove surface oxide layers, rust, and dust, improving the brightness, luster, and corrosion resistance of gear surfaces.
Specifically, lubrication coating spraying technology is also an effective surface treatment method. It uses spraying equipment to spray lubricant in an atomized form onto the surface of the gear, forming a uniform lubricating film. This lubricating film can fill small indentations and unevenness on the surface of gears, reduce the friction coefficient of the contact surface, and thus reduce friction and wear.
Overall, appropriate surface treatment can significantly improve the performance of heavy-duty gear parts, reduce friction and wear during use, and increase their service life. But the specific handling method needs to be selected and optimized based on factors such as the material of the gear, the operating environment, and working conditions.
