powder metallurgy oil bearing is mainly made of what raw materials powder

 

Generally speaking, powder metallurgy oil-bearing is mainly made of raw material powder through pressing, sintering, shaping, oil immersion and other processes. Today's machines are mostly of a higher degree of automation. Daily output is relatively large, most of the products can be formed at a time, so the larger the batch better production. And now use a little less mold may do hundreds of thousands of words, more words may do more than a million. But the cost of the mold is relatively high, so it is not easy to do if the batch is small, and the time to replace the mold is also long.

Powder metallurgical oil bearing can generally be formed once, basically without cutting. Cost is lighter than machining, material waste is less, so the price is cheaper. It is also in line with the current national policy of promoting energy conservation, so it is considered a technology that will not fall out of fashion.

The matrix of powder metallurgy oil-bearing has been filled with lubricating oil by vacuum immersion method, and the lubricating oil will ooze out to the running surface due to temperature rise and pumping during operation, so it can be used in occasions without adding lubricating oil.

Powder metallurgy oil bearing (oil bearing) is a kind of porous alloy products with lubricating oil in the pores. When the shaft rotates, the friction between the shaft and the oil-bearing causes the temperature of the oil-bearing to rise and the pumping action.

Lubricating oil leaks out of the friction surfaces of the inner or outer diameters of the oil-bearing when the shaft stops rotating. The lubricating oil flows back into the bearing. Therefore, the consumption of lubricating oil is very small, and can be used for a long time without external supply of lubricating oil. Very suitable for oil supply difficulties and avoid lubricating oil pollution occasions.
