提升机齿轮箱是在低速、重载下运行的,其工作条件恶劣。为了确保提升机安全、正常地运行,必须对齿轮箱运行状态进行有效和及时的诊断分析。对齿轮箱的部件失效情况的统计表明,齿轮比重约占60％。因此加强对齿轮的振动诊断的研究有重要意义。 某矿提升机减速器的振动噪声较大,且运行不平稳,经矿方要求对其做振动测试,其减速器传动系统参数与所计算的特征频率 Hoist gear box is operating at low speed, heavy load, poor working conditions. In order to ensure the safe and normal operation of the hoist, the diagnosis and analysis of the running state of the gearbox must be carried out effectively and timely. Statistics on the failure of gearbox components show that the gear weight accounts for about 60%. Therefore, to strengthen the diagnosis of gear vibration research is of great significance. A mine hoist reducer vibration and noise larger, and the operation is not smooth, the ore required by the vibration test, the reducer drive system parameters and the calculated characteristic frequency
