【摘要】：MK84250高速轧辊磨床主轴所用液体动静压轴承是决定加工质量和效率的关键部件,其温升是影响轴承的正常工作的关键因素。但由于其油膜包角及油膜压力的求解域未知,无现成资料可查,通过数值计算方法拟合了未知包角的承载量系数-偏心率函数曲线,分析了轴承结构并求解了线速度为45 m/s和60 m/s时的流量,并对温升进行了计算。计算结果与实际情况一致。
[Abstract]:The liquid hydrostatic bearing used in the spindle of MK84250 high speed roller grinder is the key component to determine the machining quality and efficiency, and the temperature rise is the key factor affecting the normal operation of the bearing. However, because the solution domain of oil film angle and oil film pressure is unknown, there is no ready-made data to check, and the load carrying coefficient-eccentricity function curve of unknown envelope angle is fitted by numerical calculation method. The structure of the bearing is analyzed and the flow rate of 45 m / s and 60 m / s is calculated and the temperature rise is calculated. The calculated results are in agreement with the actual situation.
