鞍钢半连轧厂连轧机组第一台轧机上的减速机,1986年中修后投产不久,便发生了强烈振动,危及机电设备、厂房基础的安全,使增产措施无法实施。我们受厂方委托,对减速机进行了振动测试和振动信号分析,找出了振源,排除了故障,使机器重新恢复了正常运转。一、测试方案的确定据初步分析,减速机振动的振源可能有三;其一,在齿轮传动过程中,由于轮齿刚度周期变化及加工误差、磨损点蚀的积累所引起的啮合激振;其二,滚动轴承的滚动体周期地通过下接触点引起的跳动激振;其三,回转部
The reducer on the first rolling mill of Anshan Iron & Steel Co., Ltd., a rolling mill unit of Anshan Iron & Steel Co., Ltd., soon after it was put into production in mid-1986 and underwent vigorous vibration, endangering the safety of mechanical and electrical equipment and plant foundation and preventing the stimulation measures from being implemented. We commissioned by the factory, the reducer vibration test and vibration signal analysis to identify the vibration source, ruled out the fault, the machine back to normal operation. First, the test program to determine According to a preliminary analysis, reducer vibration may have three vibration sources; First, the gear transmission process, due to gear cycle variation and processing errors, wear and tear caused by the accumulation of pitting vibration; Second, the rolling elements of the rolling bearing cycle through the next contact point caused by the beating vibration; Third, the Ministry of rotation
