应用圆弧深槽端面油膜密封的液压回转油缸泄漏特性研究
Research on the leakage properties of a rotating hydraulic cylinder with a deep circular groove oil film face seal
摘要
Abstract
The power chuck is an important component for a machine tool. In order to solve the existing problem of oil allocation for the rotating hydraulic cylinders of power chucks, a new kind of rotating hydraulic cylinder based on hydraulic slip-ring oil allocation was suggested. The deep circular groove oil film face seal technology was applied in the hydraulic slip-ting. Taking into account various viscosities, the leakage property of the seal face was simulated in detail. The experiment data proves the precision of the theoretical analysis. The rotating speed of the rotating hydraulic cylinder can be improved to 10 000 r/min. These theories provide reference for the practical application of the rotating hydraulic cylinder.关键词
