Can Adding Oil Solve the Bearing Noise Problem

Bearing noises and high temperatures are problems that arise from time to time in the manufacturing and application of electric motors; in order to solve this type of problem, improving the structure of the bearing system and selecting the appropriate lubricant are relatively common methods and measures.

In comparison, grease that is too thick has better adhesion, but creates greater resistance to bearing operation, leading to bearing heating problems. In contrast, thinner grease is favourable to the operation of bearings, but the adhesion is poorer, which is not conducive to the long-term operation of bearings. For different motors, different operating conditions, should be configured with the operating temperature appropriate grease, such as high temperature and low temperature environment operation of the grease.

In the bearing system murmur and high temperature disposal case, some people will be in the grease filling conditions by adding oil, a short period of time, as if there is a certain disposition effect on the fault, but the motor runs for a very short period of time, the lubrication effect of the oil disappeared, and at the same time, it will lead to oil into the inner cavity of the motor of the undesirable consequences.

From the theoretical analysis, the oil is not a diluent of grease, the two have no compatibility. Motor bearings more applications of lithium-based grease, its chemical composition with the oil, the nature and use of different, they can not be mixed, but also can not dilute each other. If the lithium grease and oil mixed together, the two will affect each other and cause a series of adverse consequences. On the one hand, the mixing of lithium grease and oil will lead to a decrease in lubrication effect, or even lubrication failure, affecting the normal work of the machine; on the other hand, the mixing of the lubricant will produce a chemical reaction, so that the original nature of the change, accelerating the wear and aging of the machine.
