[Car cooling fan] bearing introduction. u003cbru003eBall Bearing u003cbru003eBall Bearing has changed the friction method of the bearing. It adopts rolling friction. There are some steel balls or steel posts between the two iron rings, supplemented by some grease lubrication. This method more effectively reduces the friction phenomenon between the bearing surfaces, effectively improves the service life of the fan bearing, and therefore reduces the heat generation of the radiator and prolongs the service life. The disadvantage is that the process is more complicated, which leads to higher costs and higher operating noise. u003cbru003eOil Bearing u003cbru003eSleeve Bearing is a sleeve bearing that uses sliding friction and uses lubricating oil as a lubricant and drag reducer. It can be said that it is the most common bearing technology on the market. Due to its low cost and simple manufacturing, many products including well-known brands are still in use. Its advantages are quietness, low noise and low price during initial use. u003cbru003eMagnetic Bearing u003cbru003eThe magnetic bearing (Magnetic Bearing) motor adopts the Magnetic System (MS) design, which uses magnetic force to suspend the rotor in the air so that there is no mechanical contact between the rotor and the stator. The principle is that the magnetic induction line is perpendicular to the maglev line, and the shaft core and the maglev line are parallel, so the weight of the rotor is fixed on the running track, and the almost unloaded shaft core is used to support the anti-maglev line to form the whole The rotor is suspended in the air on a fixed orbit. Compared with traditional ball bearings and oil-impregnated bearings, magnetic bearings have no mechanical contact, and the rotor can run to a very high speed. It has the advantages of low mechanical wear, low energy consumption, low noise, long life, no need for lubrication, and no oil pollution. , Especially suitable for special environments such as high speed, vacuum, ultra-clean. Magnetic levitation is actually just an auxiliary function, not an independent bearing form. Specific applications have to be matched with other bearing forms, such as magnetic levitation + ball bearing, magnetic levitation + oil bearing, magnetic levitation + vaporized bearing and so on. u003cbru003e u003cbru003eRelated recommendation: AC fan 220v-230v http:///products-detail.asp?cpidu003d74
