Ball bearing performance
The hardness of the retainer is lower than that of the ball and ring. The material is metal (such as medium carbon steel, aluminum alloy) or nonmetal (such as iron, steel, PTEF, high polymer material). Rolling bearings (rolling, bearing) than journal bearings (Journal, bearing) rotating friction resistance is small, so at the same speed, because of friction, the temperature will be relatively low.
Ball bearings are generally used in low load mechanical transmission equipment. Because of the ball bearing bearing area is small, prone to mechanical injury serious case in the high-speed operation, so the mechanical drive heavy load often take a needle bearing in order to increase the bearing surface, improve the mechanical transmission efficiency, and reduce the mechanical injury.
Change the way of bearing friction ball bearing, the rolling friction, this method is more effective to reduce the friction between bearing surfaces, enhance the fan bearing life, it will prolong the service life of the radiator. The disadvantage is that the process is more complex, cost increases, but also bring higher work noise. |
