摘　　要：为说明油腔结构对液体静压推力轴承承载力的影响,选取环形、圆形和扇形3种常见的油腔结构,在油腔面积相同的前提下,通过求解这3种推力轴承的油膜雷诺方程发现环形油腔推力轴承承载力大于其他2种。通过试验对环形油腔推力轴承承载力计算结果进行了验证,当轴承静止时,试验结果与理论结果的一致性良好;当轴承以150 r/min转动时,试验结果与理论结果的误差保持在8%以内,说明了理论分析的正确性。In order to illustrate the effect of recess structures on load capacity of hydrostatic thrust bearings,three common recess structures,namely annular,circular and sector,are selected.Under the premise of same recess area,the load capacity of thrust bearings with annular recess is found to be larger than the other two kinds by solving the oil film Reynolds equation of these three kinds of thrust bearings.The load capacity calculation results of thrust bearings with annular recess are verified by tests.When the bearings are stationary,the test results are in good agreement with theoretical results.When the bearings rotate at 150 r/min,the error between test results and theoretical results is kept within 8%,confirming the correctness of theoretical analysis.
