1. Deep groove ball bearing installation
Deep groove ball bearing installation methods, there are two, for the press fit with the installation and installation of heating.Press fit with the installation: the inner ring and the shaft is closely fit, and the outer ring and the bearing hole with the relatively loose, but it can also be closely with. Using a pressure gauge, press the bearing on the shaft, and then attach the shaft together with the bearing into the bearing housing hole. To press fit, pay attention to the bearing inner ring on the end, to pad the soft metal material, as the assembly casing.
Heating with the installation: This installation method is more commonly used, the operation is also more effort. Is the bearing or bearing seat heating, and then use the principle of heat expansion, so that tight fit with loose fit. Is the bearing or ring into the tank for heating, the temperature is 80 ℃ -100 ℃, the heating should be uniform, after heating to be installed as soon as possible, can not be delayed. In addition, the heating temperature can not exceed 100 ℃, in order to reduce the hardness of the ring.
2. Deep groove ball bearing operation and maintenance
(1) deep groove ball bearing operating temperature should be below 60 degrees, can not exceed this value, otherwise there will be problems.
(2) to pay attention to the axial movement of components, especially the bearing clearance.
(3) bearing the inside and outside the runway, there should be no flaws.
(4) to be timely in accordance with the provisions of lubrication, lubricants or grease to be replaced in time to maintain a good oil quality.
