摘要

可倾瓦轴承因其稳定可靠的特点被广泛应用于现代工业，相关研究也蓬勃发展起来，但目前关于可倾瓦轴承预负荷系数的研究主要集中在低转速领域。以DyRoBeS软件为研究工具，取普遍使用的5块瓦可倾瓦轴承作为研究对象，分析在20 000 r/min、40 000 r/min、60 000 r/min的高转速工况下，预负荷系数对可倾瓦轴承工作性能的影响，为高速齿轮传动中可倾瓦的设计应用提供理论依据。预负荷系数从0.1增加至0.7的过程中，对功率损失影响不大，使最大油膜压力与刚度系数增加，最小油膜厚度与阻尼系数减小。预负荷系数的混合设置会影响各瓦块压力分布，同时使最小油膜厚度以外的轴承性能参数明显增加。所得结论对高转速可倾瓦轴承的优化设计起到积极的作用。

Abstract

Tilting pad bearings are widely used in modern industry because of their inherent stability，and related research has flourished. However，the study on the tilting pad bearing preload coefficient mainly focuses on the field of low rotational speed. The DyRoBeS software is used as the research tool，and the commonly used five tilting pad bearing is taken as the research object. The influence of the preload coefficient on the working performance of the tilting pad bearing under the high rotational speed conditions of 20 000 r/min，40 000 r/min and 60 000 r/min. The analysis results will provide theoretical basis for the design and application of the tilting pad in high-speed gear transmission. In the process of preload coefficient increased from 0.1 to 0.7，there is no effect on the power loss，but the maximum oil film pressure and stiffness coefficients are increased，the minimum oil film thickness and damping coefficients are decreased. The mixed setting of the preload coefficients affected the pressure distribution of each tilting pad，the bearing performance parameters except the minimum oil film thickness is obviously increased. The conclusion will play a positive role in the optimization design of tilting pad bearing with high rotation rate.
