滚动轴承打滑研究综述与展望

REVIEW AND PROSPECT OF ROLLING BEARING SLIPPAGE RESEARCH

伴随旋转机械系统向高转速、高精度和高可靠性发展,滚动轴承作为基础零部件之一是旋转机械系统非常重要的组成部分。而轴承打滑行为严重影响了旋转机械系统的稳定性、运行精度和服役寿命,因此针对滚动轴承打滑特性及运动机制的研究已成为国内外学者讨论的热点话题。研究工作介绍了滚动轴承的打滑运动机制以及损伤形式,详细总结了滚动轴承打滑的研究方法以及滚动轴承的打滑因素。最后,针对滚动轴承打滑特性的研究方法(试验法、动力学仿真)和打滑因素(工况、结构、装配参数以及故障轴承)的研究现状、不足及未来发展方向进行了探讨。

With the development of high speed,high precision and high reliability of rotating machinery systems,rolling bearings as basic components are a very important part of rotating machinery systems.Since the bearing slippage behavior seriously affects the stability,running accuracy and service life of the rotating machinery system,the research on the sliding characteristics and motion mechanism of rolling bearings has become a hot topic discussed by scholars at home and abroad.The mechanism of slipping motion of rolling bearings in the form of slip damage is introduced,and the research methods of rolling bearing slip and the slip factors of rolling bearings are summarize in detail.Finally,the research status,deficiencies and future development directions of the research methods(experimentation,dynamic simulation)and the slippage factors(working conditions,structures,assembly parameters and faulty bearings)of rolling bearings are discussed.
