Advantages and disadvantages of ceramic bearings
We cannot live without some mechanical equipment, because it is also a part of our lives. 陶瓷轴承厂家 给大家介绍一下陶瓷轴承的优缺点都有哪些？ Bearings are an important basic component of mechanical machines, etc. However, bearings are also made of many materials. There are certain differences in the mechanical equipment suitable for different materials. Ceramic bearings may not be well understood by everyone, so let the ceramic bearing manufacturers What are the advantages and disadvantages of ceramic bearings? What are the uses of ceramic bearings 1.Aircraft parts The aircraft manufacturing industry has used ball screws with ceramic balls for aircraft flap adjusters, and has also tried to use hybrid ceramic bearings in gas turbine engines. 2.Aero engines In the fuel pump of aero engine, it can work in liquid oxygen and liquid hydrogen medium for a long time. It has been proved that it has undergone 50 launch processes without damage. 3.Car The bearings used in automobiles have the highest speed requirements for turbocharger bearings, which require bearings to have good acceleration reactivity, as well as low torque, low vibration and low temperature rise under high-speed rotation. Because it has a low temperature rise during work, it can reduce the amount of lubricating oil, so the stirring resistance of the oil is reduced, the bearing torque is reduced, and the speed is increased. In addition, rail vehicles also use it, and its durability and reliability under harsh conditions have been proven. 4.Motor Motors can be used to achieve permanent insulation. When the motor is used for deceleration and energy saving devices, internal leakage can cause arc discharge. Advantages of ceramic bearings 1. It has the advantage of zero corrosion. It can be used without obstacles even in a work environment that is dissatisfied with corrosion. 2. Regardless of the sudden rise or fall of temperature, it can be unaffected. 3. The biggest feature of ceramic bearings is that they will not deform due to stress, because the elastic modulus of the bearing is higher than that of steel. 4. The density of ceramic rolling balls is much lower than that of steel, so the weight is naturally much lighter. Therefore, the centrifugal friction of the outer ring can be reduced, and the service life of natural ceramic bearings becomes longer. To sum it up: Ceramic bearing advantages: can be used in high temperature, insulation, corrosion resistance, non-lubrication occasions. Disadvantages of ceramic bearings: difficult to process and high cost.
