针对动力卡盘存在的液压回转油缸的配流和冷却问题,介绍了液压滑环在液压回转油缸中的应用,在液压滑环简化模型的基础上,用ANSYS软件分析得到密封缝隙的温度场分布,通过Vogel方程分析密封缝隙的粘度场分布,在MATLAB中用粘度函数推导和处理摩擦转矩公式,并应用实验研究验证了该关系式的正确性.为解决回转油缸的配流和冷却问题提供了一定的参考.

To solve the problems of oil-allocation and cooling for the rotating hydraulic cylinder of a power chuck, hydraulic sliprings are used in the rotating hydraulic cylinder. Based on a simplified model of the oil film face seal in the hydrostatie slipring, the temperature distribution in the gap was obtained through ANSYS analysis. The vigcosity distribution was determined using the Vogel viscosity-temperature equation based on temperature distribution. Then the frictional torque was deduced and dealt with in the MATLAB environment. Further experiments were performed to verify the correctness of these relationships. The research provides a reference for solving the oil allocation and cooling problems of rotating hydraulic cylinders.
