摘要
智能轴承是具有自感知、自决策及自调控功能的轴承单元,是高端轴承发展的主要方向。首先,分析了智能轴承的特点,总结了智能轴承的国内外研究进展和发展动态,认为目前智能轴承技术尚处在初级阶段,自决策和自调控功能尚不成熟;其次,探讨了智能轴承关键技术,包括传感器技术、自供电/无线供电技术、信号无线传输技术、轴承状态智能评估及智能诊断技术以及轴承状态智能调控技术;最后,讨论了智能轴承系统化、监测信息多样化及智能化的发展趋势。
Intelligent bearing is a bearing unit with self-perception,self-decision and self-regulation functions,and is the main development direction of the high-end bearings.The characteristics of smart bearings are analyzed,and the research progress and development trends of smart bearings are reviewed.It is concluded that the smart bearing technology is still in the primary stage,since the self-diagnosis and selfregulation functions are not mature.It is summarized that the key technologies of smart bearing include sensor technology,self-powered technology and wireless power supply technology,wireless signal transmission technology,intelligent assessment and diagnosis technology and intelligent control technology.Finally,the development trends of systematization,diversification of monitoring information and intellectualization of intelligent bearing are discussed.
