摘要

基于滚动轴承动力学理论，采用流-固-热三相耦合的数值分析方法，研究超低温环境下保持架的温度场和强度，得出保持架温度分布、应力分布以及入口流速对流体流速和流体压力的影响。结果表明：保持架温度随着入口流速的增加而降低，最高温度处于兜孔周向位置；保持架应力随着入口流速的增加而增大，最大应力处于兜孔轴向位置。研究可为解决超低温环境下轴承的延寿及可靠性问题提供参考。

Abstract

Based on the dynamics theory of rolling bearings, the fluid-solid-thermal three-phase coupled numerical analysis method is used to study the temperature field and strength of the cage in the ultra-low temperature environment. The influence of the temperature distribution, stress distribution and inlet flow rate of the cage on the fluid flow rate and fluid pressure is obtained. The results show that the temperature of the cage decreases with the increase of the inlet flow rate and the maximum temperature is at the circumferential position of the pocket; the cage stress increases with the increase of the inlet flow rate and the maximum stress is at the axial position of the pocket.Research can provide reference for solving bearing life extension and reliability problems in ultra-low temperature environment
