The numerical calculating based on reynolds equation are carried out with the help of computer program built by bearing research institute of xi ' an jiaotong university . the calculating results indicated that three lubricating oil wedge bearing with an end - to - end through gap between the horizontal combine surfaces will not be unsteady factor when the bearing load no change . but the horizontal oil film rigidity will reduce and the working position of axle journal in the bearing will change
论文利用雷诺方程对# 5轴承的三油楔水平中分轴承进行了数值计算，计算结果表明，当三油楔轴承水平中分面有贯通的缝隙而轴承的载荷不变时，三油楔轴承不会失稳，但会减小水平方向的油膜刚度，改变轴颈在轴瓦中的工作位置。
