The advantages and disadvantages of bearings, ceramic bearings

In life we can not do without some mechanical equipment, because it is also a part of our lives. Bearing is a kind of important components, the basis of mechanical machine and so on, however, the bearing is also has a lot of material, different material is suitable for the machinery and equipment, there will be differences of ceramic bearing perhaps everyone don't understand, so let bearing the author introduce you to what is the advantages and disadvantages of ceramic bearing? A, using ceramic bearing for 1, auto bearing used in the car, the speed is the most demanding turbo charger bearing, the acceleration of demand bearing has good reactivity, and under the high speed low torque, low vibration and low temperature rise. Due to its low temperature in the work, can reduce the amount of lubricating oil, so oil mixing resistance decreases, the lower bearing torque, speed up. In addition, railway vehicles also use it, its durability and reliability in harsh conditions has been confirmed. 2, using it can realize the permanent motor motor insulation, motor used for reduction and energy saving device, internal leakage can cause arc discharge phenomenon. 3, aircraft engine in aircraft engine fuel pump, it can be for a long time work in the liquid oxygen and liquid hydrogen medium, it has been proved that through 50 times launch without damage. 4 parts aircraft, aircraft manufacturing industry has been equipped with ceramic ball of the ball screw for aircraft flap regulator, also try to hybrid ceramic bearing used in gas engine. Second, the advantages of ceramic bearing 1, it has the advantages of zero corrosion. Even in resent corrosion environment, it still can be used without obstacles. 2, or sudden high temperature suddenly drops, it can also be free from any influence. 3, ceramic bearing, the biggest characteristic is not because of the stress and deformation, because elastic modulus is more high than steel bearing. 4, the density of ceramic rolling balls than steel is much lower, so the weight also is natural light a lot, so can reduce the rotational external circle of centrifugal friction, the nature of the ceramic bearing service life is longer. Summary down: ceramic bearing advantages: can be used for high temperature, insulation, corrosion resistance, no lubrication. Ceramic bearing faults: processing difficulty and high cost.
