本文对高速齿轮箱中具有节能效益的推力盘弹流润滑理论作了研究,获得了可用于生产实际的推力盘等温及热弹流润滑数值解计算程序。此外,计算和分析了表面速度、锥角、粘度和温度等对承载能力及最小膜厚的影响,并将本文数值解结果与用Dowson—Higginson 线接触理论拟合公式所得的最小膜厚值进行了比较,表明用拟合公式计算高速齿轮箱中推力盘弹流膜厚具有较大的误差。 In this paper, the energy-efficient thrust-disk elastohydrodynamic lubrication theory in high-speed gearbox has been studied, and the numerical calculation program of isothermal and thermoelastic lubrication of thrust disk can be obtained. In addition, the effects of surface velocity, cone angle, viscosity and temperature on the bearing capacity and the minimum film thickness were calculated and analyzed. The results of the numerical solution were compared with the minimum film thickness obtained by the fitting formula of Dowson-Higginson line contact theory The comparison shows that using the fitting formula to calculate the thickness of the thrust disk in the high-speed gearbox has large errors.
