摘要/Abstract

摘要： 采用ABAQUS二次开发技术建立了20CrMnTi钢齿轮的渗碳淬火预测模型,并结合试验测试对20CrMnTi钢齿轮渗碳淬火后的渗碳层、组织、硬度与淬火畸变情况进行了分析。结果表明,齿轮渗碳淬火后,齿根处渗碳层深度约为0.7 mm,外齿圆与内齿圆部位渗碳层深度约为1.0 mm。马氏体转变量最高达97%,表面残留奥氏体含量最高为6%。齿轮近表面硬度在700 HV以上,外齿圆与内齿圆较齿根具有更高的表面硬度,心部硬度为400~420 HV。由于热应力与组织应力,齿轮渗碳淬火后发生径向膨胀畸变,外齿圆处畸变量为0.123 mm,内齿圆处畸变量为0.061 mm。硬度试验测试结果与仿真结果吻合较好,模型预测精度约为93%。

Abstract: Using ABAQUS secondary development technology, a predictive model for the carburizing and quenching process of 20CrMnTi steel gear was established. Combined with experimental tests, the carburized layer, microstructure, hardness, and quenching distortion of the gear after carburizing and quenching were analyzed. The results show that after carburizing and quenching, the carburized layer depth at the tooth root is about 0.7 mm, while that at the outer and inner tooth circle is approximately 1.0 mm. The maximum martensite transformation reaches 97%, and the highest surface retained austenite content is 6%. The near-surface hardness exceeds 700 HV, with the outer and inner tooth exhibiting higher surface hardness than the tooth root, and the core hardness ranges between 400-420 HV. Due to thermal and phase transformation stresses, the gear exhibits radial expansion distortion after carburizing and quenching, with a distortion of 0.123 mm at the outer tooth circle and 0.061 mm at the inner tooth circle. The hardness test results agree well with the simulation and the model prediction accuracy is approximately 93%.
