application of powder metallurgy oil bearing bearing

Powder metallurgy bearing is mainly used in general raw material powder by pressing, sintering, shaping, immersion process made. Now the machines are mostly relatively high degree of automation. Production is relatively large, most of the products can be formed at a time, so the larger the better production. And now with the mold less than a few words can do hundreds of thousands, more than one million words may do more than. But die cost is relatively high, so the lot of small words will not be done, and the time to replace the mold is long. Powder metallurgy oil bearing (oil bearing) is a kind of porous alloy product containing lubricating oil. When the shaft rotates, the friction between the shaft and the bearing of the increased oil bearing temperature and pump function.

Copper based powder metallurgy oil bearing

Cu Fe based powder metallurgy bearing working principle: powder metallurgy bearing the porous sintered body, the impregnation of 10%~40% (volume fraction) of lubricating oil, to oil supply condition. During operation, the bearing temperature, because the expansion coefficient of oil than metal, thus automatically enter the sliding surface to stop working when the oil lubricated bearings, and decreased with the temperature being sucked back into the void.

Cu Fe based powder metallurgy bearing is to iron and copper powder as raw material, through mould pressing, sintering, vacuum oil immersion after processing. The products are widely used in household appliances, electric tools, textile machinery, chemical machinery and automobile industry etc..

Copper iron base powder metallurgy bearing processing type: can processed into a straight sleeve, flange shaft sleeve, gaskets, slider, non-standard shaped pieces, supporting non-standard custom-made products.

Copper iron base powder metallurgy bearing application characteristics: powder metallurgy bearings oil in general is mainly used raw material powder by pressing, sintering, shaping, oil impregnation process and. The production machine with higher degree of automation, the daily output is relatively large, once most of the products forming, so the better batch production.

And now for a little less mold might do a few hundred thousand, many words can do more than one million. But the mold cost is relatively high, so the small batch if not done well, and mould replacement time is long. Powder metallurgy oil bearing in general will be able to shape, basically no cutting processing. The cost is lower than the machine processing, the material waste also is little, the price therefore is quite cheap. Also in line with the current national policy to promote energy conservation, so that this is a technology that will not fall behind.

Powder metallurgy oil bearing the matrix have used vacuum impregnation method with lubricating oil, and in operation due to the elevated temperature and the pump suction, the lubricating oil will seep to the running surface, so it can be for no extra lubricant occasions.
