一、问题的提出 精轧机是高速线材厂关键设备之一,它的运行状况直接关系到生产的正常运行和企业的经济效益。包钢线材公司的精轧机由美国摩根公司进口,主要包括辊箱和锥箱两大部分,辊箱中有4对齿轮,锥箱中有一对螺旋伞齿轮。由于辊箱和锥箱的齿轮轴起着不同的作用,当齿轮发生故障时,判断是哪一根轴的齿轮至关重要,它影响到设备管理人员设备检修的决策。包钢线材公司的每架精轧机与地面成45°,相邻两架成90°,测振时在精轧机处测得的振动信号,既有齿轮的振动,又有轴承、联轴器、齿轮箱的振动,相邻机组的振动以及周围环境的噪声。而利用包络幅值解
First, the question put forward Rolling mill is one of the key equipment of high-speed wire rod mill, its operating status is directly related to the normal operation of production and the economic benefits of enterprises. The finishing mill of Baotou Steel Wire Company is imported by the United States Morgan Company. It mainly includes two parts of roller box and cone box, four pairs of gear box in the roller box, and a pair of spiral bevel gear in the box. Due to the different roles of roller shafts and cone shafts, it is of crucial importance to determine which one of the shafts the gear is in when the gear is faulty, which affects the decision of the equipment manager to overhaul the equipment. Each finishing mill of Baotou Steel Wire Rod Co., Ltd. makes 45 ° with the ground and the adjacent two frames form 90 °. The vibration signals measured at the finishing mill during vibration measurement include the vibration of gears and the bearings, couplings, Gear box vibration, adjacent units of vibration and the surrounding environment noise. While using the envelope magnitude solution
