Cylindrical roller bearing size: to inspect the bearing is bearing

Overload reason mainly is the main engine failure or improper installation, only use the right analysis methods, procedures, steps, to find the real reason for the failure. Light weight, high strength: imported bearing shell has a variety of different types, from high overall quality of the cast iron casting, or high precision stamping steel manufacturing, at the same time of light weight with large intensity, the two different methods of stamping steel products has the characteristics of the lighter. Also used for metal surface, fill gaps and antirust effect, colloidal stability is keep in storage and use of grease colloid stability, liquid mineral oil is not the performance of the precipitation from the fat. The causes of high temperature bearing include: insufficient lubrication or excessive lubrication, lubricants contains impurities, heavy load, bearing damage, inadequate clearance and high friction produced by the oil seal and so on. Com believes that many friend at the time of repair their own cars have come into contact with the bearing in the car, you should be familiar to it, after all, bearing is modern mechanical facilities inside very important a part, its main function is to support the inside of the machine body of revolution, thus reducing it in the movement of the friction produces in the process, at the same time protect mechanical moving backwards when the accuracy of the often used in metallurgy, wind power generation, mining equipment and aerospace. If NSK bearings in the check and the surrounding parts of the oil seal has presented the adverse symptoms, please be replaced, in order to avoid bad NSK bearing oil seal can cause damage. （ Figure hot installation, normally for larger bearing installation, not by heating the bearing or bearing is impossible, because with the increase of the size, The public number: pump pipe home) , the greater the force needed for the installation. Will let bearing box end cover to offshoring, use TAB to get between bearing housing and the space between the outer ring, possible axial spring force on the outer ring, in order to reduce the axial shaft floating. Coarse grinding bearing ring morphology and physical and chemical inspection method after pickling raceway and the guard should be uniform dark gray, defect ring after pickling plaques are mainly distributed in the race and gear side, as shown. Wash the groove in the coarse, should avoid to turn the bearing, etc. With the brush after roughly clear the dirt on the adhesion in the bearing surface, in on the fine cleaning tank, in fine cleaning tank, bearing rotation to gently to clean. So maintenance regularly to bearing when reversing, through the above treatment, most of the motor shaft current, has no harm in essence of electric mechanism. Specific steps are as follows: initial adjustment: equipment hoisting in place after the first square, steel ruler of hoisting in place ready to adjust the equipment such as the coupling on the preliminary survey and adjustment; Note: anchor bolt supporting surface must meet the relevant equipment installation requirements, the need to keep the benchmark side slightly higher than the prime mover, otherwise, the equipment to find is meaningless.
