摘要

摘要: 以中心点支承圆形弹性金属塑料瓦为研究对象，依据润滑理论，建立推力轴承数学模型，采用有限元软件仿真分析，并对其润滑性能进行数值模拟。结论表明，油膜压力使瓦面产生凹变形，油膜温度使瓦面产生凸变形，轴瓦整体变形为凹变形。根据轴瓦变形情况将轴瓦瓦面修型为进出油坡形厚度为0.05mm、长度为8mm的中凸形型面。相同工况下，最小油膜厚度随着弹性复合层厚度的增加而减小，随着钢基层厚度的增加而增加。当弹性复合层加厚到10mm时最高油膜温度出现峰值，不利于轴承散热。钢基层厚度改变对于最高油膜温度及轴瓦整体温度的影响甚微，可忽略不计。

Abstract

The circular elastic metalplastic padsupported by the center point is taken as the research object Based on thelubrication theory

the mathematical model of thrust bearing is established Thesimulation analysis is carried out by using finite element software

and thelubrication performance is simulated The conclusion shows that the oil filmpressure causes concave deformation of pad surface

the oil film temperaturecauses convex deformation of pad surface

and overall deformation of bearingbushing is concave According to the deformation of bearing pad

the bearing padsurface is modified into a mediumconvex surface with a slope thickness of 005mmand a slope length of 8mm Under the same working conditions

the minimum oilfilm thickness decreases with the increase of elastic composite layer thicknessand the minimum oil film thickness increases with the increase of steel basethickness When the elastic composite layer is thicker to 10mm

the maximum oilfilm temperature appears peak value

which is not conducive to bearing heatdissipation The change of steel base thickness has little effect on the maximumoil film temperature and the overall bearing temperature

which can beneglected
