摘要

针对在常温下,齿轮轴向滚轧不能加工大模数齿轮,本文研究了齿坯加热后的齿轮轴向温轧工艺。利用DEFORM-3D软件,对齿轮的轴向温轧工艺进行有限元模拟,研究了温轧过程中的滚轧力、温度场、应力场的特点。通过滚轧试验,成功滚轧出了齿数44,模数2.5mm的齿轮,齿轮轮齿成形良好,与数值模拟结果吻合,验证了理论分析的正确性。
        Aiming at the normal temperature, the axial rolling of the gear can not process large modulus gear. In this paper, the axial warm rolling process of the gear after heating is studied. Using the DEFORM-3 D software, the finite element simulation of the axial warm rolling process of the gear was carried out, and the characteristics of rolling force, temperature field and stress field during the warm rolling process were studied. Through the rolling test, the gears with the number of teeth 44 and the modulus of 2.5 mm were successfully rolled out, and the gears were well formed, which was consistent with the numerical simulation results, it verified the correctness of the theoretical analysis.
