The job standard items are usually as follows: cleaning bearings and bearing related components;check the size and finishing of the connecting parts;installation;inspection after installation of bearings; providing lubricant;
I hope to open the bearing packing before it is ready to be installed. General grease lubrication, no cleaning, direct filling grease. Lubricating oil lubrication, general cleaning is not necessary, but the instrument or high-speed bearings, such as cleaning with clean oil, remove the coating on the rust inhibitor. Remove the rust inhibitor bearings, easy to rust, so can not be placed aside. Furthermore, have grease sealed bearings, not directly use cleaning.
Bearing installation method, because of the bearing structure, coordination and conditions vary, in general, due to the rotation of the shaft, so the inner ring need interference fit. generator bearing Cylindrical bore bearings, press by multiple presses, or by hot charging. Tapered bore, directly installed in the taper shaft, or sleeve installation. clearance is more coordinated, and the outer ring has an interference amount, which is usually pressed by a press, or a cold contraction matching method is installed after the cooling. With dry ice as coolant and cold contraction fit the installation, moisture in the air condenses on the surface of the bearing. Therefore, appropriate rust prevention measures are needed.
