摘　　要：针对转炉减速器齿轮承载越来越高的现状,利用齿轮啮合理论、摩擦学、传热学、赫兹接触等理论,研究了齿轮的相对滑动速度及轮齿摩擦系数的变化规律,计算出了齿轮沿啮合线摩擦热流量。通过建立转炉减速器齿轮瞬态温度场有限元分析模型,获得了齿轮瞬态本体温度场,齿轮工作时间与温度梯度的关系表明越是能迅速达到热平衡状态,对转炉减速器齿轮传动越有利。该研究结果为转炉减速器齿轮的安全使用提供了理论依据,为以后转炉减速器齿轮瞬态本体温度场的快速建模和分析提供了方法。With the improvement of gear capacity for converter reducer, the theories of gear engagement, tribology, heat transfer and Hertz contact were applied to research the change law of relative sliding velocity and friction coefficient of gear teeth. The heat flux along the line of action was calculated. By means of setting up the finite element analysis model of transient temperature field for the gear of converter reducer, the gear bulk transient temperature field was achieved. The relationship between working time and temperature gradient was analyzed and the results showed that the faster the converter reducer gear reached the heat balance, the better the gear transmission system worked. The research results provided the theory basis for the safe use of converter reducer gear and presented the method of rapid modeling and analysis for transient bulk temperature field.
