In order to prolong the service life of the bearing, to focus on industrial SKF bearing maintenance, repair, in order to prevent accidents, ensure the reliability of operation, increase production, economy.
1, bearing cleaning: remove bearing overhaul, the first recorded appearance of the bearings, confirmation of lubricant remaining quantity, sampling inspection by the lubricant after washing, bearing. As a cleaning agent, general use gasoline, kerosene.
2, bearing maintenance and judgment: in order to determine whether removing FAG bearing can be used to inspect, clean in bearings. Check the raceway surface, rolling surface, with the surface state, increasing shelf wear, bearing clearance and the size of a precision injury, abnormal.
3, the bearing lubrication purpose: rolling bearing lubrication to reduce friction and wear of the bearing internal, to prevent sticking.
4, the installation of the bearing: bearing is installed correctly, affect the accuracy, performance, service life. Therefore, the design and assembly departments for bearing installation to fully study.
5, in the hope that the forthcoming before installation, just open the shaft lubrication, no cleaning, directly filling grease. Lubricating oil, general need not cleaning, however, instruments or high speed bearings, to wash with clean oil, antirust coating in the NSK bearing removal.
Installation method 6, bearings, bearing structure, coordination, because conditions vary, in general, due to rotate, so the inner ring interference fit is required.
7, mounted to the housing, general clearance, there is interference in the outer ring, usually with presses enter, or have shrink fit method of installing cooling.
