介绍了水润滑陶瓷主轴的概念和特点,概述了水润滑陶瓷主轴在国内外的发展趋势和工业应用,对水润滑陶瓷主轴的关键技术和急需解决的问题从4个方面进行了评述,主要包括:1)材料摩擦学方面,需加强对低成本、高性能水基润滑添加剂、高韧性硅基陶瓷材料、长寿命陶瓷涂层的研究;2)轴承润滑建模与分析方面,需综合考虑陶瓷零件加工精度、水基润滑剂非牛顿效应、高速湍流效应、温黏效应等因素,实现精确建模与分析;3)高速主轴轴承-转子系统非线性动力学方面,需借助降阶分析理论的最新成果,实现系统非线性行为的精准预测与调控;4)表面织构在水润滑陶瓷主轴上的应用方面,需加强对表面织构和宏观结构的协同效应、表面织构的设计与优化,以及陶瓷表面织构的低成本高效加工方法的研究。

The concept and characteristics of water-lubricated ceramic spindle are introduced.The development trend and industrial application of water-lubricated ceramic spindle at home and abroad are summarized.Finally,the key technologies of water-lubricated ceramic spindle and the problems to be solved urgently are reviewed from four aspects,mainly including.1)In material tribology,the research on low-cost and high-performance water-based lubrication additives,high-toughness silicon-based ceramics and long-life ceramic coatings should be strengthened.2)In the modeling and analysis of bearing lubrication,the machining accuracy of ceramic parts,non-Newtonian effect of water-based lubricants,high-speed turbulence effect,temperature-viscosity effect and other factors should be considered to achieve accurate modeling and analysis.3)In the nonlinear dynamics of high-speed spindle bearing-rotor system,the latest results of reduced-order analysis theory should be used.4)For the application of surface texture on water-lubricated ceramic spindles,the synergistic effect of surface texture and macrostructure,the design and optimization of surface texture and the low-cost and high-efficiency machining methods of surface texture should be strengthened.
