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.
