摘　　要：使用ABAQUS软件建立了直齿圆柱齿轮冷滚打成形有限元模型,主要分析了冷滚打成形过程中冷滚打成形变形力的分布情况。研究结果表明:成形过程中,滚打成形力呈现动态周期性变化,最大滚打力出现在开始阶段;随着冷滚打过程进行,滚打力梯度减小;滚打力随着滚打轮转速的增加而增加。The finite element model of cold roll-beating for straight teeth cylindrical gear was established and the distribution of the forming force during cold roll-beating was mainly analyzed with the software ABAQUS.The results show that the forming force is a periodic change during the forming process,the maximum roll-beating force appears in the initial stage;the gradient of the rolling force decreases with continuation of the cold roll-beating;roll-beating force increases with the rotational speed roller increasing.
