Abstract

High-speed motorized spindle is the core component of high-speed machining machine tools, and thermal error is the main factor affecting the machining accuracy of the motorized spindle. Reducing thermal error has become the most important research topic in the case of motorized spindles. The development status of the cooling strategy of the motorized spindle is explored, and the methods to improve the cooling efficiency of the motorized spindle are discussed. Some representative research results of the cooling strategy of motorized spindles at home and abroad are reviewed. Based on summarizing the related research results on cooling strategies for the core components, such as the stator, rotor and bearing of the motorized spindle, this paper analyzes the advantages and disadvantages of various cooling strategies and their applicable working conditions, and the future development direction of motorized spindle cooling strategies is discussed. The combination of various channel structures and the cooling strategy of the stator outer ring of the motorized spindle will improve the cooling efficiency of the motorized spindle, and research on the motorized spindle core cooling will become more and more important. In addition, the cooling system of the motorized spindle bearing, stator, and rotor can be improved at the same time, and the heating problem of the motorized spindle can be solved.
