Generally, solid smoothing agent accounts for 20-30% of the conflict surface area. The smoothing principle of graphite-copper sleeve self-smoothing bearing is that in the process of sliding conflict between the shaft and the bearing, part of the graphite particles are transferred to the conflict surface of the shaft and the bearing, forming a layer of stable solid smooth diaphragm to avoid direct adhesion and wear of the shaft and the bearing.
This rational combination combines the respective functional advantages of metal alloy and non-metal wear reduction materials, complementing each other, which not only has the high bearing capacity of metal, but also gets the smooth function of wear reduction materials.So it is especially suitable for no refueling, less refueling, high temperature, high load or water and other environments.
Graphite copper sleeve, also known as self-smoothing bearing, is a product with self-smoothing function, which is developed on the conflict surface of the copper sleeve as the metal matrix with orderly and appropriate size holes, and embedded with graphite or molybdenum disulfide as a solid smoothing agent.
At present, graphite copper sleeve has been widely used in engineering machinery, metallurgical machinery, mining machinery, locomotive bracket, steel rolling equipment, ship machinery, mold equipment, textile machinery, gas turbine and other low-speed and heavy-load, high-speed and light-load occasions.
