某炼钢厂仿西班牙产品制造的板坯横移车运行机构采用分别驱动、变频调速、无人操纵自动控制技术。其减速器齿轮多次发生点蚀、塑性变形、断齿等事故或故障 ,严重时曾出现轮齿全部被剃光的现象。经分析 ,其根本原因是承载能力不足。通过重新选型设计 ,加大减速器中心距 ,彻底根除了断齿等事故隐患 A steel mill imitation of Spanish products slab horizontal shift truck operating mechanism were driven, frequency control, automatic control technology unmanned. The gear reducer occurs several times pitting, plastic deformation, broken teeth and other accidents or failures, serious gear tooth appeared all the time being shaved phenomenon. After analysis, the fundamental reason is the lack of carrying capacity. Through re-selection of design, increase reducer center distance, the complete eradication of accidents such as broken teeth
