固定斜面瓦推力轴承变形分析

摘要

依据润滑理论,采用有限元数值分析方法,运用ANSYS计算软件,对固定斜面瓦推力轴承的变形进行了数值模拟,并建立了轴瓦变形的油膜形状控制方程的数学模型.分析结果表明:力导致瓦面产生中凹变形,且随载荷和轴瓦厚的增大而增大;温度导致瓦面产生中凸变形,且随温度和轴瓦厚度尺寸的增大而增大;瓦面实际变形是力、热变形的叠加.该结论可为此类推力轴承的设计、应用提供参考依据,以减少产生不利于承载能力的瓦面凹变形.%According to the theory of lubrication,Numerical simulation of the deformation of the thrust bearing of the fixed inclined plane was carried out,by finite element numerical analysis method and using the ANSYS software.The mathematical model of the oil film shape control equations about of the deformation and bearing is established.Analytical result showed that the force caused the tile surface generating concave deformation,and convex deformation increased with the height and the size of the load and bearing;Tile surface temperature generated convex deformation and increased with the height and the size of the temperature of bearing bush;The actual deformation of the tile surface is the superposition of the force and the thermal deformation.This conclusion can provide reference for the design and the application of thrust bearing,to reduce the tile surface,which is not conducive to the carrying capacity of the concave deformation.
