Installation and cleaning of deep groove ball bearings

The installation of deep groove ball bearings must be carried out in a dry and clean environment. Before installation, carefully check the machining quality of the mating surface of the shaft and the housing, the end face of the shoulder, the groove and the connection surface. All mating connection surfaces must be carefully cleaned and deburred, and the unprocessed surface of the casting must be cleaned of molding sand.

Deep groove ball bearings should be cleaned with gasoline or kerosene before installation and used after drying to ensure good lubrication. Deep groove ball bearings are generally lubricated with grease or oil. When using grease lubrication, a grease with excellent properties such as no impurities, oxidation resistance, rust prevention, and extreme pressure should be selected. The grease filling amount is 30% -60% of the volume of deep groove ball bearings and deep groove ball bearing boxes, and it should not be too much. Double-row tapered roller deep groove ball bearings with sealed structures and deep groove ball bearings with water pump shafts are filled with grease, which can be used directly by the user and can no longer be cleaned.

When installing deep groove ball bearings, you must apply an even pressure on the circumference of the end face of the ferrule, press the ferrule into it, and do not directly hit the end face of the deep groove ball bearing with a tool such as a hoe to avoid damage to the deep groove ball bearing. In the case of small interference, the end face of the deep groove ball bearing ferrule can be pressed with a sleeve at normal temperature, the sleeve can be beaten with a hoe, and the ferrule can be pressed in evenly through the sleeve. For large-scale installations, hydraulic presses can be used. When pressing in, make sure that the end face of the outer ring and the end face of the housing shoulder, and the end face of the inner ring and the end face of the shaft shoulder are tight. No gap is allowed.

When the interference amount is large, it can be installed by oil bath heating or inductor heating deep groove ball bearings. The heating temperature range is 80 -100 , and the height cannot exceed 120 . At the same time, a nut or other appropriate method should be used to tighten the deep groove ball bearing to prevent the deep groove ball bearing from shrinking in the width direction to cause a gap between the ring and the shoulder. The clearance of the deep groove ball bearing should be adjusted. . The clearance value should be specifically determined according to the different operating conditions and the amount of interference. If necessary, it shall be determined by test. Deep groove ball bearings and deep groove ball bearings with water pump shafts have been adjusted for clearance at the factory and do not need to be adjusted during installation.

After the deep groove ball bearing is installed, a rotation test should be performed. Firstly, it is used for a rotating shaft or a deep groove ball bearing box. If there is no abnormality, it will run under load at low speed with power. Noise, vibration and temperature rise. If abnormality is found, stop running and check. Can not be delivered until the running test is normal.
