CPU fan oil bearing and ball bearing difference

2018-04-26 16:00:13

1, ball bearing: is a kind of rolling bearing, the spherical alloy steel ball installed in the middle of the inner steel ring and the outer steel ring, in a rolling way to reduce the friction in the process of power transmission and improve the transmission efficiency of mechanical power. 2, oil-bearing: that is, porous bearings, with metal powder as the main raw material, oil-bearing is a sintered body made by powder metallurgy. 1, ball bearings: used in low-load mechanical transmission equipment. Because the bearing area of ball bearings is small, it is easy to have serious mechanical damage in the case of high-speed operation, so in the mechanical transmission of heavy loads, needle roller bearings are often used to increase the bearing surface, improve the mechanical transmission efficiency, and reduce mechanical damage. 2, oil-bearing: using the porosity of the sintered body, so that it contains 10% to 40%(volume fraction) of lubricating oil, used in the state of self-oil supply. 1, ball bearings: ball bearings can not withstand large heavy loads, in the light industrial machinery is more common. 2, oil bearing: has the characteristics of low cost, vibration absorption, low noise, no lubricating oil in a long working time, especially suitable for work environment that is not easy to lubricated or does not allow oil dirt.
