本文叙述了新型腔内轴反馈静压轴承的特点,优点和作用原理,并与老式腔外轴反馈静压轴承作了比较。文章还以 M7120平磨为例、对该轴承的结构形式、设计、计算进行了详细的介绍与说明、附有设计图纸与最终测试、试磨结果。本文对轴反馈静压轴承的合理设计,进一步提高和完善起了积极作用,并在机械工程的应用上,具有较大的实践价值。 This paper describes the characteristics, advantages and operating principles of the new hydrostatic axial-cavity-feedback hydrostatic bearings and compares them with the old hydrostatic axial-shaft-fed hydrostatic bearings. The article also with M7120 flat grinding, for example, the bearing structure, design, calculation carried out a detailed introduction and description, with the design drawings and the final test, test results. This paper plays a positive role in the rational design, further improvement and perfection of the hydrostatic bearing with axial feedback and has great practical value in the application of mechanical engineering.
