摘要

为研究不同载荷、转速条件下,低速重载轴承的润滑性能,即油膜厚度、油膜压力及油膜流速的变化情况,利用Abaqus软件建立轴承流固耦合模型,得到油膜厚度在剖面中呈矩形分布,滚动体与内圈之间的油膜厚度小于与外圈之间的油膜厚度。接触区入口处的油膜压力逐渐增大,内滚道接触处的油膜压力大于相应的外滚道油膜压力。流固交面的油膜速度大于自由表面的油膜速度且接触区域的油膜速度最大。随着转速的增加,油膜厚度和油膜压力增加;随着载荷的增加,油膜厚度降低,油膜压力增加。

Abstract

In order to study the lubricating property of low-speed heavy-duty bearing under the condition of different loads and speed, such as the oil film thickness, oil film pressure and changes of oil film velocity. Building model of fluid-structure interaction by using ABAQUS software, and it can get a conclusion: the oil film thickness distributes in rectangular section, the thickness of oil film between the rolling element and inner ring is thinner than that between rolling element and outer ring, the oil film pressure increases gradually at the entrance of the contact zone, and the oil film pressure at the inner raceway contact point is greater than that of the outer raceway. The oil film velocity of the liquid-solid intersection is greater than that of the free surface, and the oil film velocity is the fastest in the contact zone. With the increase of rotating speed, the oil film thickness and oil film pressure increase; with the increase of load, the oil film thickness decreases, and the oil film pressure increases.
