Problems solved by technology

[0002] Many large-scale mechanical equipment, such as rollers and guide rails and pin gear pairs of standard steel bridge horizontal push-type erection mechanisms, crawler tracks and support wheels, guide wheels, and driving wheels of crawler vehicle travel mechanisms, ring gears and ring gears of excavator slewing mechanisms Metal friction components such as gears, transmission mechanisms of ball mills, slewing mechanisms of cranes, trolley drag mechanisms for heating furnaces in the metallurgical industry, etc., are often dusty at the construction site, and the friction components included in the equipment need to be exposed to harsh environments. , Working under dry friction conditions, liquid lubricating oil or lubricating grease cannot be used, which makes the friction coefficient of the friction pair very large, resulting in serious friction energy consumption and rapid wear of friction components, thereby reducing the transmission efficiency and use of the friction pair Life, and even affect the service life and safety reliability of the whole machine
