在近些年中涡轮机组的轴向振动引起了越来越多的关注。可倾瓦推力滑动轴承被广泛应用于涡轮汽轮机组来承受轴向力。润滑油膜的动特性因素对于转子及其轴承的轴向振动有很大影响。因此建立一种方法来测试推力轴承的动特性是十分有必要的。设计了一种测试一个测试推力轴承性能的实验装置,其采用了倒置式结构,可同时测量采集轴瓦的温度,油压及油膜厚度。实验结果显示出了试验工况的选择对推力滑动轴承的静动特性影响巨大。%A new rig,of which test bearing is invert structure,has been deveIoped.The faciIity aI ows a compIete set of bearing op-erating parameters to be measured.
