Auto cooling fan fan bearing system

auto cooling fan fan bearing system generally suggest zui good use ball bearings, because the life of heat fan fan often depends on the reliability of the bearing, ball bearing system has been proved to have the characteristics of rate and low calorific. Ball bearing rolling friction, the metal bead rolling, contact surface is small, small friction coefficient; And oil bearing for sliding friction, contact area is large, use for a long time, after oil volatilization, bearing is easy to wear and friction coefficient is big, the noise caused by the late life is short. The fan with good quality in addition to the large air quantity, high wind pressure, the reliability is also very important, the bearing in the form of fan using this is very important. High-speed fan shall use ball bearing ( 球轴承) While low speed fan using cheap oil bearing ( 滑动轴承) 。 Use only one bearing oil bearing fan; And ball bearing fan will need two bearing, ball bearing, is & other; 1球+ 1套” Still has the oil-retaining bearing, the ingredients. Is higher than single ball ji is auto bearing, namely Two Balls. Oil bearing life in general is 10000 hours, the single ball bearing for 30000 hours, auto bearing for 50000 hours or more ( The environment temperature setting below 25 ℃) 。 Used in fan oil bearing the copper base powder sintering and become, use oily add lubricating oil to reduce the number of sliding friction bearing and lubricating oil by lithium grease and oil special modulation. With long time of operation, the bearing inner oil can evaporate and dry, the friction coefficient increases, fan operation affected, may appear different sound, speed slow don't even turn phenomenon. And ball bearing replaced by rolling friction for sliding friction, low friction coefficient and overcomes the drawback of the coefficient of friction can become, and running stability is strong, relatively is much longer service life.
