Linear ball bearings, bearing contact Angle can be adjust heart

Using rolling bearing machine starting torque is small, be helpful for starting under load, about the size of the journal, the width of the rolling bearing is smaller than sliding bearing, can make the axial compact structure of the machine. For symmetric roller, it is to point to in the pass through the middle of the length of the roller diameter of radial plane theory, theory of asymmetric roller is big diameter ( In the radial including imaginary Angle of taper roller large end plane) 。 Some users, the heating temperature is too high with acetylene spray to heating of bearing inner hole, when the temperature exceeds ℃ ( The phase transition temperature of bearing steel) When the inside of the bearing steel microstructure changes will occur. Heat will install bearing in oil heating so that it has expanded again after installed on the shaft of the hot set method can avoid unnecessary force, the bearing in a short time to complete installation work. Otherwise there will be a bearing is not durable, frequent replacement of bearing phenomenon, said a tip here, ball bearing by load reduced half, can prolong the service life of The Times, roller bearing prolongs service life. Tempering, macro inspection to macro failure bearing inspection ( Including the size tolerance measurement and surface state examination analysis) Contact fatigue failure of contact fatigue failure refers to the bearing working surface under the role of alternating stress and failure. Labyrinth seal gap is too small and the shaft friction, and if it is found that car has had a similar phenomenon, don't drive a car, after all, life is the first place. These failures will cause the rotor shaft, the person that weigh lead to the rotor or scrapping, but the vibration value is not big, with the vibration standard ( Such as ISO specification) Vibration is qualified. The structure of thrust bearing thrust bearing is composed of bearing and thrust journal, due to uneven load distribution among each ring, the bearing capacity of per unit area is lower than single collar %. Single row angular contact ball bearing, Technical level for: prompt angular contact bearings are suitable for high speed and high precision rotation, such as high temperature, magnetic field, the water does not affect its precision, and can withstand synthetic load. Ball mill in overloading, overlap of high speed high torque at low speed under the start, and under the action of vibration equipment, radial impact, bearing chamber or bearing a metal fatigue, produce variant; Bearing or bearing outer ring and inner ring on the shaft bearing chamber clearance fit, resulting in relative motion develop blemishes. Cage materials: rolling bearing at work, heat and wear caused by sliding friction bearing, especially under the condition of high temperature operation, the effect of inertial centrifugal force increase the friction, wear, and fever, caused serious cage or fracture, the bearing can work normally.
