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: Sliding friction sleeve bearings (Sleeve Bearing) and rolling bearings (Ball Bearing) and two bearing methods are mixed. These new lubricants manufacturers have introduced new skills in bearing 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; uses lubricating oil as a lubricant and drag reducer; low noise during initial operation; low cost of production; but the bearing wear is severe; life is better than ball bearing There is a large distance. And this kind of bearing is used for a long time; because of the reason of the oil seal (the computer radiator product can not use the advanced oil seal; generally it is the general paper oil seal); the lubricating oil will gradually evaporate; and the dust will enter Bearings; then cause the fan speed to slow down; noise increase and other problems; severely due to bearing wear constitutes a sharp violent sensation caused by the electric fan. Present these appearances; either open the oil seal to refuel; or only filter the purchase of new 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 lubricated with balls; and equipped with lubricating oil. It overcomes the short life of the oil-bearing bearing; the unstable operation of the wool. 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 noise of the operation 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 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 is almost double-ball bearing. The hydraulic bearing has a common returning oil circuit; The ability of oil to leak is small.
The representative manufacturer of Rifle Bearing is CoolerMaster; currently CoolerMaster has upgraded some of its traditional oil-bearing bearing fans to Fu Bearing. As a traditional oil-impregnated bearing improvement; Laifu Bearing uses wear-resistant materials to make high oil. Hollow bearing; reduces the friction between the bearing and the shaft core; the Laifu bearing also has a reverse spiral groove and the core of the oil sump; when the fan is in operation, the oil will constitute a reverse migration; then the oil loss is prevented; Promoted the bearing life. The foil bearing fan through the selection of the above layout and parts; so that the oil and oil can be promoted significantly; and reduce the noise.
Hypro Bearing is derived from HY (Hydrodynamic Wave) PRO (Oil protect ion system); it is a patented product of the famous radiator and electric fan depicting manufacturer ADDA; also in the tradition The oil-bearing bearing has many improvements on the base. The fluid-protection system bearing and the hydraulic bearing can be said to be similar; the two depictions each use some common improvement methods; but the essence is the same as the circulating oil circuit system; The average product life can reach more than 50,000 hours.
Hydraulic Bearing is a skill initiated by AVC; it is improved on the bottom of oil-impregnated bearings. Hydraulic bearings have a larger oil storage space than oil-bearing bearings; and have a common loopback oil supply circuit. Hydraulic The operating noise of the bearing fan is significantly reduced; the service life is also very long; it can reach 40,000 hours. The hydraulic bearing is still essentially an oil bearing. However, this pass is improved; the life is much longer than that of the general oil seal bearing. Moreover, the long-distance operation of oil-impregnated bearings is low. The current hydraulic bearings are now used in AVC radiators; but not all AVC radiators use hydraulic bearing fans.
The VAPO Bearing is improved by Sunon's magnetic levitation skills; it is to strengthen the hardness of the bushing of the oil-impregnated bearing; and the special materials are selected; the inner surface is also specially processed; thus overcoming the oil-bearing bearing Defects of high temperature resistance; cooperation with magnetic levitation skills; greatly extended the life of the application.
The motor of Magnetic Bearing has magnetic suspension (MS); its magnetic induction line is straight with the magnetic floating line; therefore, the axial core and the magnetic floating line are parallel; therefore, the component of the rotor is fixed on the orbit of the operation; It is simply the unloaded shaft core supporting the diamagnetic floating line; it constitutes the entire rotor suspended; on the fixed working track. Therefore, the magnetic levitation is only a kind of auxiliary function; it is not an independent bearing method; Bearing methods; such as magnetic suspension + ball bearings, magnetic suspension + oil bearing, magnetic suspension + vaporized bearings, etc. This skill has not been recognized by European and American countries.
NANO Ceramic Bearing (NCB) is still an oil-bearing bearing in nature; it was first introduced by Foxconn in its products. The traditional oil-impregnated bearing fan wears more severely during operation; reliability during long-term operation The lower nanometer bearing is useful to overcome this problem: the ceramic bearing skill uses a special blend of special polymer materials and special additives; the bearing center uses all the special cerium oxide data; it is made by die and sintering process; The 60um of the past has been reduced to 0.3m; it has the characteristics of consolidation, lubrication and wear resistance. The nano-ceramic bearing has strong high temperature resistance; it is not easy to evaporate; this greatly prolongs the service life of the fan; the nature of nano-bearings and ceramics Similar; the more polished the more lubricated. According to the test; the average life of the fan using nano-ceramic bearings is more than 150,000 hours. This skill is not true nano-skills; the data used is not true nano-scale data; However, the word "nano" was chosen to attract eyeballs.
