Imported bearing installation method

Imported bearing installation: the installation of the bearing is correct, affects the precision, life and performance. Therefore, the design and installation of assembly department for imported bearing to fully research. Hope to work in accordance with the standards for installation. Operation standard project usually is as follows: ( 1) Cleaning imported bearing and the bearing connection parts; ( 2) Check the size of the interrelated parts and finishing; ( 3) Installation; ( 4) After installed imported bearing inspection; ( 5) Supply of lubricant. Hope before the installation, just open the packaging imported bearing. General grease lubrication, cleaning, not directly fill grease. Lubricating oil, ordinary also don't have to be clean, but, instrument or high-speed with imported bearing, etc. , to be washed with clean oil, remove rust inhibitor on the imported bearing. Remove the rust inhibitor import bearing, easy to rust, so can't place. Furthermore, have the imported bearing grease sealed, not directly use cleaning. Imported bearing installation method, because the import bearing structure, cooperate, conditions, and, generally, due to many as the axis of rotation, so the inner ring need interference fit. Import bearings cylindrical hole, multi-purpose press pressure into, or multi-purpose hot charging method. Taper hole, installed directly on the taper shaft, or use the socket installation. When installed on the shell, clearance fit more commonly, outer ring have surplus quantity, usually use the pressure into the press and or have shrink fit method of cooling after installation. Use dry ice as coolant, shrink fit installation, the moisture in the air condenses on the surface of imported bearings. So, need a good rust prevention measures.
