In mechanical engineering; there are many types of bearings; however, there are several types of bearings used on radiator products:
1. Common types: 1) Sleeve bearing with sliding conflict, 2) Ball bearing with rolling friction, 3) Mixing of two kinds of bearing methods. Valve imported pump industrial washing machine 2. Improving new technology type: In recent years New technology introduced by major radiator manufacturers in terms of bearings; for example: 1) magnetic bearing, 2) water wave bearing, 3) magnetic core bearing, 4) Laifu bearing, etc.; also improved on the basic method of bearing Cheng; the operating principle is still unchanged.
3. Generally, oil-bearing bearings and ball bearings are used on air-cooled radiators.
1) Oil-impregnated 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 higher than ball bearings Large distance. And this kind of 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 lubricating oil will gradually evaporate; and the dust will enter the bearing; Then call 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 appearances are presented; either the oil seal is turned over or the new fan is screened.
2) Ball bearings change the conflict method of the bearing; use roll friction; this method is more useful to reduce the conflict between the bearing surfaces; useful to promote the life of the fan bearing; The extension of the number is that the process is more messy; the promotion of the cost, together with higher operating noise.
