摘　　要：简要介绍了高速空冷木工电主轴的结构组成及其相对于金属切削用电主轴的一些特点,详细分析了高速空冷木工电主轴的主要热源及散热机制,建立了高速空冷木工电主轴的有限元模型,运用ANSYS有限元软件,分析了热稳定状态下空冷电主轴的温度场分布及转速对电主轴温升的影响。结果表明,在木工电主轴的冷却方式上:通过合理的设计散热结构空冷能够满足高速木工电主轴散热要求,同时空冷相对于水冷或油冷有很多优点。The structure and composition of the air-cooled high speed motorized spindle for wood-working machine and some features relative to the metal cutting motorized spindle are introduced briefly. Then the main heat sources and heat dissipation mechanism of the air-cooled motorized spindle are thoroughly analyzed, finite element model of the air-cooled motorized spindle is built, the motorized spindle＇ s temperature distribution under thermal steady state and the influence of speed are analyzed. The results show that air cooling relative to the water or oil cooling has some advantages and the reasonable heat dissipation structure design of air-cooled motorized spindle could meet the requirements of the high-speed motorized spindle for wood-working machine.
