copper sleeve bearing
Customized Copper Bearing Powder Metallurgy Industry Flanged Bronze Bushings
Powder metallurgy is to make metal or use metal powder (or mixture of metal powder and non-metal powder) as raw material, through forming and sintering, to make metal materials, composite and various types of products.P / M bearing refers to the product after the bearing processed in this way is vacuum impregnated with lubricating oil.Because this product is made of powder, the body will have tiny holes. After impregnation with lubricating oil, it will contain a certain proportion of oil.
There are many reasons for the influence of P / M density on the wear resistance of P / M copper sleeve, but the wear of materials mainly occurs in the process of surface deformation and fracture.
Therefore, the wear resistance of the friction pair will be improved by the favorable factors to improve the surface strength and toughness. Powder metallurgy materials usually have a certain amount of voids, which makes the strength and toughness of the materials decrease. Generally speaking, when the density of P / M material is more than 7.0g/cm3, the hardness increases sharply. Because under the condition of high density, the material can not only increase the effective bearing area, but also fully play the role of alloying.Of course, the wear resistance of P / M copper sleeve is also affected by the pore shape and size

There are pores on the surface and in the body of the oil-bearing, which can be impregnated with a certain amount of lubricating oil, the surface roughness after the shaping process is small and forms a hardening layer, the apparent hardness is low, and there is a certain deformation and shrinkage after being pressed into the hole seat. During the processing, installation and maintenance, full attention should be paid to these characteristics to ensure the good performance of the oil-bearing.
