In the routine work of rolling bearing, all to consume every day and the additional a certain amount of dry oil lubrication grease of needs, so can in time replenish the core that corresponding lubricant grease become the rolling bearing lubricating maintenance according to the actual consumption situation.Thereby the quality of mending fat cycle, benefit fat amount and institute's repairing fat just becomes the big main points of three in the rolling bearing lubricating maintenance.The benefit fat mode of rolling bearing commonly used mainly contains to concentrate and mends fat and artificial two kinds in the fat of mending at present.Concentrate to mend fat and be actually a concentrated benefit fat system that forms by oil conservator center, oil feed pump, pipeline, distributor and control system etc., under the control of control system, periodically the lubricant grease in the oil conservator is added to the bearing the inside by pipeline, distributor and each filling-up area.
Its defective is:
1. because does not wait from the distance of each lubricating point at the oil conservator center, easy formation is excessive apart near bearing stuffing, the situation of the bearing stuffing deficiency of distance, thereby the stuffing amount inequality of each lubricating point;
2. because the grease pipeline is longer usually, the pressure of required greasing is also relatively large, make the oil sealing on the close together bearing tend to be damaged, cause grease oil leakage phenomenon to take place, cause the undesirable condition of grease waste and befouling environment because of being trapped in to store in the bearing chamber because of pressure is excessive;
3. because most of lubricating point is far away from oil conservator centre distance, make the travel time of grease in pipeline longer, have in addition can surpass 1 year, cause the oil quality that arrives each lubricating point seriously to descend, influence lubrication effect;
Oily soap segregation phenomenon takes place, causes the pipeline blockage situation in 4. remote oil transportation under the big situation of pressure easily, regular pickling pipeline, unimpeded to guarantee oil circuit, thereby the workload of daily maintenance is bigger.
Artificial benefit fat is with oil gun or hydrant cart, and according to the predetermined benefit fat cycle (as several weeks or several months), manual each lubricating point of giving refuels.Its shortcoming is: refuel by rule of thumb, volume read-out is wayward; Can't implement the hand oiling operation to the lubricating point that poisonous and harmful and staff can't touch; Time-consuming, the effort not only dirty but also tired, do not meet environmental protection and Economy requirement.And, adopt the artificial major part work bearing of mending the repairing of fat mode, in the cycle, 60% time was in lubricated (in earlier stage) or owed in the bad lubricating status in lubricated (later stage), thereby general effect is relatively poor at the lubricated fat of mending.
