Cylindrical roller bearings, in the grease after the operation for a short period of time, the grease was thrown out (thrown to the end cap), resulting in roller and raceway between the lack of grease, lubrication poor. Decomposition found that the roller has round circumferential friction marks, but also on the roll, but compared to the roller is very slight. And there are relatively sound bearings, abnormal sound.Is this phenomenon normal? What if it doesn't work? What was the reason? What's the solution? StopThanks for your help!Assuming the grease is no problem, viscosity, consistency, selection is no problem If exclusion is the problem of grease, what other reasons can this be the case? ?
If the grease is dry, adhesion is not good, some of the high temperature grease stored for a long time will be dry, it will apply to the bearing is easy to get rid of, especially now the winter oil solidification, the lubrication effect is less. It is recommended to use low temperature grease in winter or add some oil to dilute it. The best way is to change the grade of grease. If the inner ring of the bearing can be removed, grease can be filled from it.
Normal phenomenon: your choice of grease is too thin, choose a high degree of consistency. 2: mechanical revolution is too fast. 3: Grease adhesion is not high. Three possibilitiesHangzhou Xingang Petrochemical Co., Ltd. specializes in producing and selling grease and lubricating oil. Tip answer
Grease over dry, thin will affect the effect, but also with the brand of grease is also related, you can try several kinds of grease, to see what kind of effect is bestChangshou City Kazakhstan axis electrical and mechanical materials trade, we are agents of a variety of well-known bearings
I carefully read your question, I think the following talk about my views, this system from the point of view of the design, are questionable, at least the following several aspects of the design problem, put forward for reference only:1, the system does not have [oil seal], can only say that the design of the beginning of the consideration is somewhat lacking.2, [] general should choose roller bearing oil bath lubrication [], [] instead of grease, because the roller in the roller bearing [] [] in the grease, the grease has a strong crowding out of [], which leads to bad lubrication.3, [] grease generally rely on the mechanism of working temperature Shenglai improve grease liquidity, but need to have [] to seal and prevent the overflow of grease, no seal mechanism design [] summary, this place is only [] However, boundary lubrication, boundary lubrication [] [generally used for oil lubrication], [grease] rather than
The higher the speed, the greater the centrifugal force, this point should be mastered. If the grease of good quality, from the bearing chamber to consider the change of the bearing chamber space, the sides of the bearing sealed by using injection nozzle gun grease can improve the lubrication condition.
