Abstract The purpose of this paper is to investigate the static and dynamic characteristics of the high-speed water-lubricated spiral-groove thrust bearing (SGTB) considering cavitating and centrifugal effects. A turbulent flow lubrication model was established based on gas-liquid two phase flow, and the influence of cavitation and centrifugal force on the static and dynamic characteristics was analyzed for the SGTB. An experiment setup was developed to measure the static and dynamic characteristics of the SGTB. The result shows that the proposed model with cavitating and centrifugal effects is more accurate than that without those two effects, the effect of the cavitation and centrifugal force should be considered when the modified Reynolds number exceeds 0.3.

考虑空化和离心效应的高速水润滑螺旋槽推力轴承的静动态特性

摘要 本文的目的是研究考虑空化和离心效应的高速水润滑螺旋槽推力轴承（SGTB）的静态和动态特性。建立了基于气液两相流的湍流润滑模型，分析了气蚀和离心力对SGTB静动态特性的影响。开发了一个实验装置来测量 SGTB 的静态和动态特性。结果表明，所提出的具有空化和离心效应的模型比没有这两种效应的模型更准确，当修正雷诺数超过0.3时，应考虑空化和离心力的影响。
