摘要
介绍一种底部内嵌圆弧的改进型椭圆轴承。采用动压润滑理论,计入紊流及温粘效应,对其静、动特性进行了计算分析,对计算结果进行了验证。通过与传统椭圆轴承的对比分析计算,显示该轴承具有更优的性能。
An elliptical bearing with bedded are is introduced. Using dynamic pressure lubrication theory and taking turbulence and thermal effect into consideration, the characteristics of the modified elliptical bearing are studied and the calculation results have been verified. By comparison with conventional elliptical bearings, the bearing indicates more advanced performances.
