The bearing method refers to the bearing type used by the air-cooled radiator fan. In mechanical engineering, there are many types of bearings; however, there are several types of applications on the radiator: sleeve bearings with sliding conflicts and These three types are mixed with rolling friction ball bearings and two bearing methods. In recent years, new radiator manufacturers have introduced new technologies in bearings; such as magnetic bearings, water bearings, magnetic core bearings, and Laifu bearings. The basic method of the bearing is improved; the operating principle is still unchanged. Usually the air-cooled radiator is mainly used oil bearing and ball bearing.
Oil-bearing bearings are sleeve bearings that use sliding conflicts; lubricants are used as lubricants and drag reducers; low noise during initial operation; low cost of production; but the bearing wear is severe; life is much larger than ball bearings And the bearing is used for a long time; due to the reason of the oil seal (the computer radiator product can not use the advanced oil seal; usually the usual paper oil seal); the lubricant will gradually evaporate; and the dust will enter the bearing; The fan speed is slow; the noise is increased; the severe ones will cause the violent sensation caused by the wear of the fan due to the wear of the bearing. These images are presented; either the oil seal is turned over or the new fan is screened.
Ball bearings change the conflict method of the bearing; the roll friction is used; this method is more useful to reduce the conflict between the bearing surfaces; useful to promote the life of the fan bearing; thus extending the service life of the radiator The shortcoming is that the process is more messy; the promotion of the cost, together with higher operating noise.
