The classification of the bearing

High speed bearing; Belong to non-contact magnetic levitating bearing axis, temperature, wear equivalent problem, with, in non-contact bearing, magnetic levitation bearing compared with gas bearing, magnetic levitation bearing gas, gap between the rotor stator is generated by the magnetic force, not dependent on the speed of gas dynamic pressure effect, in all range of rotation speed can achieve reliable non-contact support. Peripheral velocity of magnetic suspension bearing limit can be more than 400 m/s without lubrication bearing, magnetic suspension bearing is not dependent on the lubrication conditions. Or without lubrication conditions do not allow the lubricating medium dye living environment, the use of magnetic suspension bearing can be used. Magnetic suspension bearing not only no lubrication medium pollution, and does abrasive equipment environment due to wear and tear, so, in the high vacuum and high temperature conditions, as well as its application in the medical field adjustable bearing stiffness: magnetic levitation bearing supporting stiffness can be adjusted online, can help in the rotating machinery smoothly through speed, reduce the equipment vibration damping bearing: dynamic imbalance of the rotating machinery is the main source of vibration. When the rotating machinery revolve around its center of mass, unbalanced vibration will be suppressed. Through the control strategy of the adjustment of the magnetic suspension bearing, can achieve the effect of the vibration reduction and maintenance-free bearing: traditional bearing lubrication system needs regular maintenance. Wear and fatigue damage of the bearing is also an important reason stop machine maintenance. Magnetic suspension bearing at work without friction and wear, and don't need lubricating oil system do to help, so, can work long time maintenance free. This trait for distribution is scattered, the maintenance is difficult situations not always apply. For example, in the application domains such as aerospace, gas, drilling platform, and maintenance-free characteristics of magnetic suspension bearing can play an important role.
