【摘要】：以往打滑分析大多侧重对超高转速极轻载荷工况中的滚动轴承进行分析,此处重点针对相对转速较低而载荷较高的大型滚动轴承打滑机理进行研究。以风电轴承为例,构建了轴承承载特性与滑差分析理论模型,研究了径向游隙、滚子有效长度、滚子数对滚动轴承内部接触载荷分布的影响规律,结果表明径向游隙和滚子数对滚动轴承最大承载滚子接触载荷的影响相比滚子有效长度而言更为显著。在载荷分布特性研究的基础上,基于正交试验法系统研究了径向载荷、内圈转速、滚子直径、径向游隙、润滑油黏度等不同因素对轴承滑差演变的影响权重及其影响机理,研究发现各种滑差组合参数对轴承滑差生成与演变影响权重不同,其中径向载荷对滑差影响最为显著。
[Abstract]:The skidding of rolling bearing analysis mostly focused on the ultra high speed light load conditions are analyzed, focusing on the relatively low speed to high load and large rolling bearing sliding mechanism is studied. The wind power bearing as an example, constructs a theoretical model analysis of bearing characteristics and slip, the radial clearance, effective length the number of roller, roller rolling contact bearing load distribution influence of internal, the result shows that the influence of radial clearance and the maximum number of rolling bearing roller bearing roller contact load than the effective length of roller is more significant. Based on the load distribution on the orthogonal test method was studied based on the radial load, inner ring speed, roller the diameter, radial clearance, viscosity of lubricating oil of different factors on the influence mechanism of the evolution of the weight bearing slip and its influence, it is found that the combination of slip The parameters are different to the weight of the bearing slip generation and evolution, in which the radial load has the most significant effect on the slip difference.
