| 摘 要： | 重载齿轮是指传递功率大、承载大、低速、受冲击载荷大的齿轮,技术要求其具有优良的耐磨性能、较高的接触疲劳强度和弯曲疲劳强度等,同时具有较高的抗冲击和承载能力,所以需要对其进行强化热处理,以提高综合力学性能及使用寿命。重载齿轮常用的强化热处理工艺有渗碳淬火、渗氮以及感应淬火等。本文综述了重载齿轮上述3种热处理技术的应用情况及进展,并提出重载齿轮真空低压渗碳的应用前景。

| Abstract: | Heavy duty gear refers to the gear with large transmission power,large load,low speed and large impact load.Therefore,it is required to have excellent wear resistance,high contact fatigue strength and bending fatigue strength,so it is necessary to modify its surface in order to improve its surface hardness and service life.The common surface modification methods of the heavy duty gears are carburizing heat treatment,nitriding heat treatment and induction quenching and tempering treatment.In this paper,the research status and progress of the above three kinds of heat treatment of the heavy duty gears are reviewed,and the application prospect of vacuum low pressure carburizing for heavy duty gears is also proposed. |

| Keywords: | heavy duty gear carburizing quenching nitriding induction quenching vacuum low pressure carburizing |
