For as long as possible in good condition to maintain the performance of the bearing was required to maintenance, repair, in order to prevent accident arrangement to ensure the reliability of operation, improve the productivity and economy. To maintain the best conditions of mechanical operation of the corresponding operation standard, on a regular basis. Content includes monitor running status, supplement or replacement of lubricants, remove the check on a regular basis. As maintenance issues in the operation, have bearing the rotation of the sound, vibration, temperature, the state of the lubricants and so on.
Bearing clean: remove bearing repair, first record the appearance of the bearing, confirm the residual stock of lubricant, sampling inspection with lubricant, Low Price INA SCE248 Bearing http://www.fagbearings-hk.com/newproduct/INA-SCE248-bearings-5505.html . Common use gasoline, kerosene as a cleaning agent.
Tear open come down to the bearing cleaning, rough washing and fine washing, respectively in the container, put a metal mesh bottom first, make the bearing is not direct contact with dirt from the container. Coarse when cleaning, if to spin bearing with dirt, can damage the bearing rolling surface, should be pay attention to. In coarse clean oil, use a brush to remove grease, adhesive, after clean, roughly into fine cleaning).
On the basis of the effect on the bearing load, status of ring spinning things, and to ring load can be divided into fixed load, turn the load and rocking back and forth three loads.
A. fixed load
Synthesis of radial load assumed by the scope of parts of the ring groove, and the corresponding to shaft or shell looks right scope of the corresponding parts of the wind. The load bearing in Sweden called fixed bearing load.
Unique area of the fixed load is synthesis of radial load and relative static ring. Assume a fixed load ring of ordinary can choose the suitable of loose.
B. turn load
Effect on the bearing ring of synthetic radial load vector along the circumferential direction, the progressive assumed by any part of the race, and accordingly the delivery to any part of the shaft casing hole appearance. This load is called turning load, and is called cyclic load.
Turn the load of the unique place is synthesized radial load vector and the relative rotating ring. Take turn load ring and the shaft or housing holes should be chosen GuoLin or interference fit. If see fit and proper installation, use gap between you and me will send themselves slip phenomenon, thus will cause the contact surface friction losses, friction heat, make temperature rise sharply, bearing destroyed soon. To the volume of the over surplus quantity according to the operation condition and decide, in the bearing under the load utility office, not actuating ring on the shaft or shell hole right appearance revealed "creeping" phenomenon for the principle.
Effect on the bearing ring of synthetic radial load vector in the ring of a certain region within the scope of relatively rocking back and forth, for the race to a certain area range, and phase to pass to axis or a certain region of the shell hole appearance, or utility on the bearing load is impact load and vibration load, the load direction or digital change often, this kind of load is called waggle load, and is not the direction of load.
Bear the waggle load bearing, especially when the bear the burden of the Netherlands, in the outer ring shall think fit and the use of interference fits. Inner ring waggle rotates, general inner ring sees fit and appropriate when using reversed loading. However, sometimes the outer ring must be within the enclosure to bearing to swim
