动静压轴承是在静压轴承基础上发展的新型轴承。该轴承在启动和低速时以静压效应为主,在高速时则以动压效应为主。与静压轴承相比,它具有结构简单、调试方便、挤压膜效应高的优点;与动压轴承相比,又具有使用速度范围广(包括零速度),耐磨性能佳、使用寿命长、起动力矩低、可靠性好、工作精度高等优点。动静压技术应用的广阔前景正越来越为人们所认识。
Dynamic and static pressure bearings are static bearings in the development of new bearings. The bearing in the start-up and low-speed static pressure-based, dynamic pressure in the high-speed-based. Compared with hydrostatic bearing, it has the advantages of simple structure, convenient debugging and high squeeze film effect. Compared with hydrodynamic bearing, it has wide range of use speed (including zero speed), good wear resistance and long service life , Low starting torque, good reliability, high working precision and so on. The broad prospects for the application of hydrostatic pressure technology are becoming more and more recognized.
