Abstract

The operating quality of bearings has also led to higher criteria with the growing status of the manufacturing industry in social production. The eccentricity ratio of the bearing system is particularly susceptible to change during operation as a result of the external load, which has a direct impact on the lubricating properties. On the one hand, a reasonable eccentricity ratio will improve the bearing's lubrication performance, increase stability, and better meet processing requirements; on the other hand, it will result in uncontrollable bearing behavior and may even cause the real world to deviate from the theoretical design model. The study aimed to analyze and discuss the current findings on the change in bearing eccentricity ratio. More than 100 related articles have been summarized, and bearing behavior research results, such as lubrication and load-bearing characteristics, are discussed. This paper discusses the progress of research on the eccentricity ratio problem of fluid-lubricated bearings, as well as the effect of eccentricity ratio change on bearing lubrication characteristics for bearings using different lubricating media. Active control measures to mitigate the negative impact of changing bearing eccentricity ratios are also presented. After analyzing and summarizing the relevant literature, it has been found that the eccentricity is one of the important factors affecting the lubrication characteristics of bearings.

Keywords: Fluid lubricated bearings, eccentricity ratio, lubrication medium, lubrication characteristics, bearing characteristic, active control.
