Product Description
Magnetic bearing is supported by the magnetic field of load or suspension of a new type of rotor bearings, or magnetic bearings. Bearing this in recent years has developed rapidly, especially in the high-speed, low friction, high (low) temperature and vacuum environment of more. Such as the magnetic levitation machine tool spindle, magnetic levitation rail machine, with its precision and speed support, far more than the traditional forms of support.
According to the source of magnetic force of magnetic bearings and its controllable can be divided into Active Magnetic Bearing (AMB), Passive Magnetic Bearing (PMB), Active Passive Magnetic Bearing (APMA).
Active magnetic bearing stiffness, can be precise control, but is expensive; Passive magnetic bearing stiffness small, but small suspension power, and cheap prices.
Active magnetic bearing (AMB) is controlled by the magnetic field of non-contact providing support to the rotor stability suspended in space and the dynamic performance control system regulated by a new type of high-performance bearings, is a typical example of the Electrical and Mechanical integrated products, its research involves mechanical, electrical, electronics, rotor dynamics, control theory and computer science, will serve as rolling bearings, plain bearings and air bearings, and other traditional mechanical bearing the upgrading of products that can reach many of the traditional mechanical bearing technology can not achieve the technical indicators, as most of this century - the future of one of the bearings. Its characteristics are:
(1)Be allowed to achieve high rotor speed. By magnetic bearings in the rotor can be supercritical, hundreds of thousands per minute to the running conditions, the rotation speed only restricted by the intensity of rotor material.
(2)Small friction power. In the 10000 rpm, magnetic bearings power dissipation only about hydrodynamic lubrication of the journal bearings 6%, only 17% of rolling bearings, which are of important significance of energy conservation.
(3)Low maintaining cost, long life. The magnetic bearing is to rely on magnetic suspension Journal, the relative movement between the surface there will be no contact, and there is no friction, wear and contact fatigue life of the issue, and the reliability of electronic components in the rated working conditions, much higher than the mechanical components, magnetic bearing life and reliability are much higher than in conventional type of bearings.
(4)Magnetic bearings without lubrication, thus there is no lubricant on the pollution of the environment. In a vacuum, radiation and prohibit the lubricant applications, such as vacuum technology, ultra-clean and sterile room or very pure media and so on, magnetic bearings have incomparable advantages. In general applications, because of eliminating the lubricant storage, filtration, cooling, recycling facilities, in the price and space occupied, it is entirely possible to compete with and plain bearings.
(5)Magnetic Bearing system is flexible adjustment of stiffness and damping, and able to safely beyond the rotor critical speeds. In industrial applications, magnetic bearing not only for aerospace sector, the nuclear industry, but also been rapidly applied to the military sector and the industrial sector based on the hundreds of different types of rotary or reciprocating machinery. Such as Stirling refrigerator (IR night vision), thermal Turbine (submarine), Stirling heat pump, high-speed grinder, high-speed milling machinery, high-speed lathes, high-speed motor, centrifuges, turbine compressors, vacuum pumps, achieved by the scope of the technical indicators:
(1)Speed: 0 ~ 8 x100000rpm
(2)Diameter: 14 ~ 600 mm
(3)Single bearing capacity: 0.3 ~ 5 x 10000N
(4)The use of temperature range: -253 0C ~ 450 0C
(5)Stiffness: 100000 ~ 100 million N / m.
