1, the installation of bearings must be dry, clean environment under the conditions. Before installation, carefully check the mating surface of the shaft and shell, the face of the convex shoulder trench and connection quality of surface processing. All match the connected surface must be carefully cleaned and remove the burrs, casting raw surface must be in addition to net sand.
2. Before bearing installation clean and dry before use gasoline or kerosene, and to ensure good lubrication, bearings generally use grease lubrication, oil lubrication can be used. With grease lubrication should be used free of impurities, anti-oxidation, rust and extreme pressure performance superior grease. The grease filling is 30% -60% of the bearings and the bearing capacity of the container, not too much. With sealing structure of the double row tapered roller bearings and pump shaft bearing filled a good grease, users can directly use, not for cleaning.
3, bearing installation must be imposed on the circumference of the ferrule end face of the equal pressure, pressed into the ring not want first-class tools to tap the bearing face, so as not to damage the bearing. At room temperature in the case of a smaller amount of interference with the sleeve to suppress use a hammer to beat the sleeve through the sleeve rings evenly pressed into. If large quantities of installation can be a hydraulic press. Indentation, should ensure that the outer end and shell shoulder end, the inner face and the shaft shoulder ends pressed, does not allow gaps.
4.When the amount of interference, we can use the oil bath heating or induction heating bearing the installation, the heating temperature range is 80 ℃ -100 ℃, the maximum can not exceed 120 ℃. At the same time, the application of nuts or other appropriate method for fastening the bearing, the width direction in order to prevent the bearing cooling contraction have a gap between leaving the ring and shaft shoulder.
5, single row tapered roller bearing end of the installation should be carried out clearance adjustment. Clearance values should be specifically identified under different use conditions and with the size of the amount of interference. When necessary, should be tested to determine. Double row tapered roller bearings and pump shaft bearing at the factory adjust the clearance, the installation without further adjustment.
6, bearing installation should be carried out rotation test, first used in the rotating shaft or bearing housing, without exception, then the power of the no-load, low speed, then gradually increase as the operation of the rotation speed and load, and to detect noise, vibration and temperature rise, abnormal, should stop running and check. Before running the test is normal delivery.
