Porous bronze powder metallurgy material calcined oil bearing has many advantages, first, the oil bearing, a metal alloy containing a uniform distribution of non-metallic component made of powder metallurgy products, it can be made of porous material, oxide dispersion alloys, ceramics, andcarbide, metal alloys containing uniform fine crystal structure. Many ways, good oil bearing processing precision radial crush strength, oil content, surface roughness and applied load, the speed of the shaft and the pore structure has certain specifications need to be considered in the roasting oil bearing standard, oil-bearing during the manufacturing process, the green compacts, and the sintered body density, size change is very important. Compared with other powder metallurgy material, bronze powder produced oil bearing radial crushing strength higher friction coefficient is smaller bearings in the use of the process, the temperature more stable, the oil bearing connectivity pore structure whether small decision with the level of the oil absorption amount of the entire bearing. In the roasting process, should determine the size and density of the good oil bearing a corresponding adjustment of the bearings, vacuum under immersion oil treatment would be more effective! |
