摘　　要：利用分析软件ABAQUS建立了有限元模型,分析了铜合金齿轮冷滚打成形过程的温度场效应,研究了冷滚打轮转速对齿轮表面温度分布的影响。结果显示:最高温度出现在成形初期的咬入阶段,随着冷滚打过程的进行,齿轮表面温度不断下降;在滚打轮转速增加过程中,齿轮表面温度逐渐降低。FE model was established with the analysis software of Abaqus. The temperature field efIi：ct during the copper alloy gear cold rolling was analyzed. The effect of roller rotation rate on the temperature distribution of cold rolling was researched. The results shows that, the maximum temperature appear on the bite stage of the initial; the surface temperatures on the gear decrease unceasingly with the continuation of cold rolling process; in the rotation rate of roller increasing, the surface temperatures on the gear decrease gradually.
