Powder Metallurgy Sintered Bronze Bushing Oil Immersed Bronze Sleeve Bearings

 

Product description

PM oil bearing is a porous alloy product with lubricating oil in the pores. When the shaft rotates, due to the increase of friction temperature between the shaft and the bearing or the pumping effect, the lubricating oil will seep out of the inner diameter friction surface of the bearing. When the shaft stops rotating, the oil will return to the inside of the bearing, which is the so-called self-lubricating oil bearing. Therefore, the consumption of lubricating oil is small, and it can be used for a long time without external supply of lubricating oil. It is very suitable for the occasion of difficult oil supply and avoiding lubricating oil pollution. Compared with the general cast metal alloy bearing, the oil bearing does not need oil supply mechanism, and the design can be very simple. In addition, the tiny pores of the inner sliding surface of the oil bearing will cause "oil pressure leakage", thus affecting its load and increasing the friction coefficient. As the users gradually understand the characteristics of oil-bearing, develop its advantages and avoid its disadvantages, PM oil-bearing is gradually widely used.

The advantages of P / M oil bearing:

1. Less noise than rolling bearing;

2. Small vibration Library

3. Simple products
4. Can omit processing operation, save material and energy
5. No need for special oil supply mechanism, no need to add lubricating oil from the outside. 6. Large freedom of shape design
7. It can be made into several kinds of metal or metal and non-metal composite materials which can not be made by general casting method. It is suitable for mass production with low price
8. Can be made into porous metal materials

The lubrication of P / M metal products includes solid lubrication and oil lubrication. Oil lubrication is to immerse the lubricating oil in the porosity of P / M products through the vacuum oil immersion process. In the non operation state, the lubricating oil fills its pores. During operation, the shaft rotation heats up due to friction, the bearing expands to reduce the pores, and the lubricating oil overflows to the friction surface to isolate the friction sub surface The surface plays a lubricating role; when the shaft stops rotating, the bearing cools and the pores recover, and the lubricating oil is sucked back to the pores, so as to realize self lubrication. During the working period of the bearing, it can not add lubricating oil for a long time or even for life. Although it is possible to form a complete oil film in oil bearing, in most cases, this kind of bearing is in the mixed friction state of incomplete oil film.
