摘要

针对弧齿锥齿轮渗碳淬火过程中因齿面变形引起的鼓形长度过大及齿面硬度达不到要求从而产生噪声、振动、加速齿轮副损耗的问题,运用DEFORM-HT有限元软件对弧齿锥齿轮轮齿动态热边界渗碳淬火过程进行了模拟分析,研究了冷却介质温度、淬火槽入口速度、齿轮保温温度、扩散阶段碳势等4个主要参数对齿轮鼓形长度和齿面硬度的影响;采用正交试验设计分析方法,以齿轮鼓形长度和齿面硬度为优化指标,通过离差和方差数值计算分析得到了最佳工艺参数。结果表明,当介质温度为100℃、入口速度为1.5 m/s、保温温度为835℃、碳势为1.0%时,鼓形长度最小、齿面硬度满足实际生产对齿面58,6,4HRC的硬度要求。

Abstract

In order to solve the problem that the drum length is too large and the hardness of the tooth surface is less than the requirement of noise,vibration and acceleration of the gear pair,the DEFORM-HT finite element software is used to simulate the spiral bevel gear. The effects of the four main parameters such as the temperature of the cooling medium,the inlet speed of the quenching tank,the temperature of the gear insulation and the carbon potential of the cooling and diffusion stage on the drum length and tooth surface hardness are studied. Secondly,the orthogonal experimental design and analysis method is used to optimize the index of gear drum length and tooth surface hardness. The optimum process parameters are obtained by numerical analysis of variance and variance. Finally,the results show that when the medium temperature is 100 ℃,the inlet speed is1. 5 m/s,the holding temperature is 835 ℃,the carbon potential is 1. 0%,the drum length is the smallest,the hardness of tooth surface satisfies the hardness requirement of the actual production.
