Radiator bearing classification

The bearing form refers to the bearing type used by the air-cooled radiator fan. In mechanical engineering, there are many types of bearings, but there are several types of bearings used in radiator products: sleeve bearings using sliding friction and ball bearings using rolling friction, and mixing of the two types of bearings. In recent years, new radiator technology manufacturers introduced new technologies in bearings, such as magnetic bearings, water wave bearings, magnetic core bearings, and Laifu bearings. These are also improved on the basic form of the bearing, and the operating principle has not changed. . Oil-impregnated bearings and ball bearings are mainly used on ordinary air-cooled radiators.

It is understood that the oil-impregnated bearing is a sleeve bearing that uses sliding friction. Lubricating oil is used as a lubricant and a drag reducing agent. The initial operation is low in noise and low in manufacturing cost, but the bearing is severely worn and has a long life compared with the ball bearing. Big gap. Moreover, such a bearing has a long service life. Due to the oil seal (the computer radiator product is impossible to use a high-grade oil seal, generally a common paper oil seal), the lubricating oil will gradually evaporate, and dust will also enter the bearing, thereby causing the fan. The speed is slow, the noise is increased, and so on. Seriously, the fan eccentricity causes severe vibration due to bearing wear. In these cases, either open the oil seal and refuel, or just eliminate the purchase of a new fan.

The ball bearing changes the friction mode of the bearing and adopts rolling friction. This method is more effective in reducing the friction between the bearing surfaces, effectively improving the service life of the fan bearing, and thus prolonging the service life of the radiator. The disadvantage is that the process is more complicated, resulting in higher costs and higher operating noise.
