摘　　要：采煤机上的行星架主要作用是传递动力,在35Cr Mo钢行星架上应用了亚温淬火工艺。结果表明,亚温淬火的显微组织是回火索氏体和铁素体,亚温淬火能提高冲击韧性,得到更深的淬硬层。同时,该工艺节省了能源,减少了对环境的污染,提高了生产效率,具有明显的经济效益。The main role of the planetary gear is transmission power. Subcritical quenching process was applied to the 35 Cr Mo planetary gear. The results show that the microstructure of subcritical quenching process is tempered sorbite and ferrite, and it can improve impact toughness and get deeper quench hard layer. And then, it can reduce the energy consumption and the pollution of the environment,give rise to the production efficiency,with obvious economic efficiency.
