| Abstract: | The turbopump bearing is required to be reused for many times, under such a requirement, how to improve the working life of the bearing has become a research focus. In this paper, the technical characteristics of solid lubricated bearing and the research progress of wear life and fatigue life under low temperature, high speed and heavy load were summarized. The research orientation and key point of the high life and high reliability turbopump bearing were prospected. |
