对静压支承中的静压止推轴承、静压滑环等液压元件的简化模型——旋转对称环形密封缝隙进行了深入研究 ,探讨了这种缝隙中油液粘度在变粘度条件下的分布规律 ,在此基础上推导出了环形静压支承进口和出口油液的温升计算公式 ,得出了有意义的结论 ,为设计出结构合理、性能优良的液体静压支承提供了理论依据 The simplified model of the hydrostatic thrust bearing, hydrostatic slip ring and other hydrostatic components in the hydrostatic support, rotary symmetrical annular seal gap were studied in depth, and the distribution of oil viscosity under variable viscosity condition was discussed. Based on this, the temperature rise calculation formula of annular hydrostatic bearing inlet and outlet fluids is deduced, and the conclusion is drawn that it provides a theoretical basis for designing a hydrostatic bearing with reasonable structure and excellent performance
