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, the bearing methods used in the radiator products are classified according to their basic operating principles: Sleeve bearing with sliding friction and Ball Bearing with tumbling friction and two kinds of bearing methods are mixed. These new technologies introduced by major radiator manufacturers in recent years, such as magnetic float Bearings, fluid protection system bearings, hydraulic bearings, Laifu bearings, nano-ceramic bearings, etc. are also improved on these fundamental bearing methods; the basic operating principle is still unchanged. /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
Sleeve Bearing is a sleeve bearing that uses sliding friction; smooth oil is used as a smoothing agent and drag reducing agent; the initial operation noise is low; the production cost is also low; but the bearing wear is severe; the life is better than the ball bearing There is a large distance. And this kind of bearing takes a long time; because of the reason of the oil seal (the computer radiator product can not use the advanced oil seal; usually it is the general paper oil seal); the smooth oil will gradually evaporate; and the dust will enter Bearings; then lead to slower fan speed; increased noise and other problems; severely due to bearing wear and tear caused by the electric fan caused by the violent sensation. Present these appearances; either open the oil seal to refuel; or only filter the purchase of new electric fans.
Single Ball Bearing (1 Ball+1 Sleeve Bearing) is an improvement on traditional oil-impregnated bearings; the method of sliding friction and tumbling friction mixing is used; in fact, a ball bearing is used to match an oil bearing to reduce the cost of double ball bearings; The rotor and the stator are smoothed by balls; and matched with smooth oil. It overcomes the short life of the oil-bearing bearing; the unstable running hair. Killing the old Xian Xing. The single ball bearing absorbs the advantages of the oil bearing and the double ball bearing. The life of the bearing was promoted to 40,000 hours; the defect was after participating in the ball; the running noise increased; but still less than the double ball bearing.
The double ball bearing (2 Ball Bearing) is attributed to the superior bearing; the method of tumbling friction is adopted; two ball bearings are selected; the rare steel balls in the bearing surround the axis; when the fan page or the axis changes, the steel ball follows the transformation. Because they are all spheres; so the friction is better than the Huai 嬖诼┯ 嬖诼┯ .. The advantages of the double ball bearing is the long life; about 50000-100000 hours, good anti-aging performance; suitable for higher speed fans. The drawback of the double ball bearing is that the production cost is high; and the noise is the highest at the same speed level. The double ball bearing and the hydraulic bearing have better sealing; especially the double ball bearing. The double ball bearing is completely embedded in the fan; Some are not directly touched by the outside world. In a sealed environment; the working environment of the bearing is relatively stable. Therefore, the other large-diameter electric fan of 5000 rpm almost uses double ball bearings. The hydraulic bearings have a common returning oil path; so smooth The ability of oil to leak is small.
