Bearings form refers to air-cooled radiator fan -shaped bearing class used . In mechanical engineering , bearing classes shaped very much, but bearing in the form of the radiator used in accordance with the basic principles of classification will then work in three ways: using a sliding friction sleeve bearings (Sleeve Bearing) and the use of rolling friction ball (Ball Bearing) and two types of bearings mixed forms of these three . In recent years the major bearing manufacturers in terms of radiator launch of the new technologies, such as magnetic bearings , bearing protection system fluid , hydraulic bearings, to Fu bearings, nano-ceramic bearings are also made ??to improve these fundamental bearing on the above form The basic operating principle is still no change .
Oil-bearing (Sleeve Bearing) is sliding friction sleeve bearings, and the use of oil as a lubricant DRA , the initial use of low noise operation , low manufacturing cost , but this severely worn bearing , ball bearings have life than big gap. And this bearings over time, due to the oil seal ( computer radiator can not use high-grade oil seals, generally is ordinary paper seals ) , oil will gradually evaporated, and the dust will enter the bearing , causing the fan slow speed , noise increases and other issues, but also because of a serious bearing wear caused severe vibration caused by eccentric fan . These phenomena , or open seal oil , or eliminated only to purchase another new fan.
One Ball (1 Ball +1 Sleeve Bearing) is a traditional oil- bearing improvements, sliding friction and rolling friction hybrid form , in fact, is to use an oil- bearing ball bearing with a way to reduce the cost of double ball bearing , it between the rotor and the stator are lubricated with the ball , and with oil . It overcomes the short oil bearing life, running instability problems, while rising costs are extremely limited . One Ball absorbed the advantages of oil- bearing and double ball bearings , bearing life will be raised to 40,000 hours , the disadvantage is added after the ball , run the noise has increased , but still less than double ball bearings.
Dual ball bearing (2 Ball Bearing) bearing a relatively high-end , in the form of rolling friction , using two ball bearings , there are several pieces of tiny ball bearings around the axis , or when the axis of rotation of the fan page , follow the ball that rotates . Because all spheres, so friction is small, and there are no leakage problems. Advantages double ball bearing is long life, about 50000-100000 hours ; good anti-aging properties , suitable for high speed fan. The disadvantage is the high double ball bearing manufacturing costs , and maximum noise level at the same speed . Double ball bearings and wind closed hydraulic bearing better, especially double ball bearings. Double ball bearing fan to be embedded in the whole , there is no direct contact with the rotating part of the outside world . In a sealed environment, bearing the working environment is relatively stable. Therefore, the level of 5000 rpm , almost all large-diameter dual ball bearing fan . The hydraulic bearing due to its unique formula also back the oil , so the possibility of a small oil leak . Lai Fu bearings (Rifle Bearing) technology on behalf of vendors is CoolerMaster, currently CoolerMaster has most of its traditional oil- bearing fan upgrade soon blessing bearings. As a traditional oil- bearing improvements to Fu bearings with high wear-resistant material hollow bearing oil , reducing the friction between the bearing and the shaft, also with a blessing to reverse the spiral groove bearing and gear sump shaft, when the fan is running the oil will form a reverse migration , thus avoiding the loss of oil , thus enhancing the bearing life. Lai Fu bearing fan and parts through the use of the above structure , making oil and oil retention capacity has increased significantly , and reduces noise.
Fluid bearing protection system (Hypro Bearing) Its name comes from HY (Hydrodynamic wave, hydrodynamic waves ) PRO (Oil protect ion system, oil guard system ) , the Department of renowned design radiator and fan ADDA manufacturer of patented products, but also in the traditional oil bearing based on a number of improvements made ??. Hydraulic fluid bearing and bearing protection system can be described as the same thing , two designs each with a number of unique improvements , but the essence is the same loop hydraulic system , all aspects of performance is roughly equal. Typically the product life of up to 50,000 hours .
Hydraulic bearing (Hydraulic Bearing) technology pioneered by the AVC , is based on the improvement of oil-bearing comes . Hydraulic bearing has a larger space than the oil- bearing reservoir , and a unique style oil circuit loop . Hydraulic bearing fan noise significantly reduced , life is also very long , up to 40,000 hours . Hydraulic bearing essentially remains an oil bearing . But this has been improved bearing life than ordinary seal greatly extended , and inherits the advantages of oil-bearing - small operating noise . Currently hydraulic bearing AVC has been applied in the radiator , but not all have adopted AVC radiator hydraulic bearing fan.
Vaporization bearing (VAPO Bearing) by Sunon maglev technology improvements will come , is to strengthen the oil bearing bushing hardness , and the use of special materials , its inner surface is also specially processed , so that does not overcome the oil bearing the disadvantage of high temperature , and then with magnetic levitation technology , greatly extended service life.
Magnetic bearings (Magnetic Bearing) motor magnetic levitation (Magnetic System, MS) design, the magnetic flux lines and magnetic lines perpendicular to , the axis of the core and the magnetic lines are parallel , so the weight of the rotor is fixed on the running track, the use of shaft is almost no load in the opposite direction of the top support maglev line , form the entire rotor floating on fixed orbits . Therefore , only an auxiliary function maglev fact , not a separate bearing forms , specific applications have to meet the other bearing forms, such as magnetic levitation + ball bearings , magnetic levitation + oil bearing , magnetic bearings , etc. + vaporization . This technology has not been recognized by the European and American countries.
Nano-ceramic bearings (NANO Ceramic Bearing, NCB), in essence, is still a sleeve bearing is determined by Foxconn in their products first introduced. Traditional oil-bearing fan in the course of serious wear and tear, the lower the reliability of prolonged use. Nano-bearing effectively overcome this problem: ceramic bearing technology uses a special polymer materials with special additives fully integrated, comprehensive bearing core Opteron dioxide using a special material, the use made ??of die and sintering process, the crystal particles 60um from the past down to 0.3um, a firm, smooth, wear-resistant properties. Nano-ceramic bearings have a strong temperature capability, less volatile, which greatly extends the life of the fan, nano-ceramic bearings of a similar nature, the more wear more smooth. According to tests, the average life of the fan using nano-ceramic bearings are more than 150,000 hours. This technology is in fact not true nanotechnology, material used is not true nanoscale materials, but the wording is such a nanometer nothing to attract the eye.
