摘　　要：分析了迁钢公司炼钢作业部3号转炉倾动减速机的设计原理和实际使用状况，结果表明，齿面硬度偏低是二次箱大齿轮齿根处产生胶合现象的主要原因。采取改变淬火和回火的温度和时间等措施，使齿面硬度达到HB310—350后，大齿轮的综合力学性能明显改善，使用寿命延长。This paper analyse the No. 3 converter tilting decelaration machine design principle and using conditions of Qian＇an company steelmaking department. The result shows that the main reasons of tooth root gluing at secondary box large gear is low tooth surface hardness. By means of modifing the quenching and tempering temperatureand time, the gear surface harness reaches HB 310- 350, which leads to the significant improvements of large gear mechanical properties and prolonged service life.
