Cooling fan ball bearing and the comparison of oil bearing
The general reliability will directly affect the cooling fan of the cooling fan bearing using full length. And the cooling fan bearing common have two kinds of ball bearing and oil bearing, is the most widely used in the market now. Though often use the cooling fan, but I still have a lot of people still don't understand the cooling fan of ball bearing and oil bearing what is the difference? Ball bearing is through metal ball rolling, due to rolling conflict, the contact surface is small, conflict coefficient is small. Oil bearing for sliding conflict, the contact area is large, a long time, the oil will quickly evaporate, simple make excessive bearing wear, increase the conflict coefficient, the noise will be getting larger, the shorter the stature, the use. General ball bearing fans need two bearings, ball bearings, or with oil bearing components, the double ball bearing is more advanced than single ball. Generally in the same environment conditions a good oil bearing generally for 25000 hours, the single ball bearing for 30000 hours, the double ball bearings for more than 50000 hours. Oil bearing of the cooling fan is made of copper base powder sintering, need to add lubricating oil to reduce the number of sliding friction, if the fan work long time did not increase the lubricating oil, the oil will make bearing inner evaporation drying, increase the conflict, the fan is not running smoothly, there will be a slow speed may not transfer phenomenon. The ball bearing is replaced by rolling conflicts sliding conflict, conflict coefficient improved conflict coefficient of simple faults, so running stability is strong, full of relatively is much longer. On cooling fan bearing and what is the difference of oil bearing, share here today. The cooling fan using the way of bearing is very important, high-speed electric fans are commonly use ball bearing, and low-speed electric fan is use the cheap oil bearing.
