摘要/Abstract

摘要： 根据某型号航天器动力齿轮用钢的化学成分,用JMatPro仿真软件计算材料的热物性参数。根据齿轮模型及热处理工艺参数,用Deform有限元软件进行渗碳淬火仿真分析,确定了渗碳过程中的齿面碳含量变化、淬火过程中轮齿显微组织的变化。最后,根据人字齿轮特点及航天器齿轮的精度控制要求,通过改变淬火工艺参数优化淬火后轮齿畸变情况。结果表明,当淬火工艺为在空气中预冷30 s,80 ℃热油淬火1200 s,-100 ℃深冷7200 s时,畸变量控制效果较好,符合产品要求。

Abstract: According to the chemical composition of the steel for a spacecraft power gear, the thermal-physical property parameters of the material were calculated by means of JMatPro simulation software. Based on the gear model and heat treatment process parameters, carburizing and quenching simulation analysis was carried out in Deform finite element software to determine the change of carbon content on the tooth surface during carburizing process, and the change of microstructure of the gear teeth during quenching process. Finally, according to the characteristics of herringbone gears and the precision control requirements of spacecraft gears, the distortion of the gear teeth after quenching is optimized by changing the quenching process parameters. The results show that when the quenching process is pre-cooling in air for 30 s, quenching in hot oil at 80 ℃ for 1200 s and then deep cooling at -100 ℃ for 7200 s, the amount of distortion is controlled better and meets the product requirements.

Key words: CSS-42L steel, herringbone gear, heat treatment, carburization, quenching, distortion control
