摘　　要：以混凝土蜗壳海水循环泵齿轮箱为研究对象,用热网络法建立该循环泵齿轮箱的热平衡方程,通过建立功率损耗、热阻、对流换热系数计算模型,求解热平衡方程组,并预测该循环泵齿轮箱关键节点的温度,进而证明该循环泵齿轮箱关键位置的安全性、稳定性;同时为下一步的齿轮箱优化提供数据。Taking the concrete spiral case seawater circulating pump gearbox as study object, the thermal hal- ance equation is established by means of thermal network. Then the equation is solved by establishing a calculation model of the power consumption, thermoresistance, convection coefficient of heat transfer. Thus it could predict the key nodes temperature of circulating pump gearbox, and then the security, stability of the key position of circulating pump gearbox are proved. Meanwhile this result provides the data for the optimization of gearbox
