Tell you what is a ball bearing

Ball bearing is a kind of rolling bearings, the spherical alloy steel ball, steel ring and the outer steel ring in the middle of the installation, to scroll way to reduce the friction in the process of power transfer to and improve the efficiency of mechanical power transmission. Ball bearing can't bear the heavy load of larger, more common in the light industry machinery. Ball bearing is also called the ball bearings. How about ball bearing work ball bearing consists of four basic components: ball ( 球) And the inner ring ( 内圈) , the outer ring ( 外环) With the retainer ( 笼子或护圈) 。 And retainer hardness compared with ball bearing and ring is low, its material with metal ( Such as: medium carbon steel, aluminum alloy) Or non-metallic ( Such as: iron, dragon, PTEF, polymer materials) 。 Rolling bearing ( 滚动轴承) Journal bearing ( 轴颈轴承) The rotation of the frictional resistance is small, so the same speed, the temperature will be lower because of friction. About the role of the cage, watching a video. Ball bearings are generally used in low load mechanical driving devices. Because of ball bearing load bearing area is small, appear easily in the case of high-speed serious mechanical damage, so often adopted in the heavy load of mechanical drive roller bearing to increase the bearing surface, and improve the efficiency of mechanical transmission, at the same time reduce the mechanical damage. Ball bearing has changed the way of bearing friction, adopts rolling friction, this way is more effective in reducing the friction between the bearing surface phenomenon, improve the service life of the fan bearing, thus to extend the service life of the radiator. Defect is process is more complex, higher cost, but also bring higher noise.
