低速重载齿轮故障的振动分析与安全校核

VIBRATION ANALYSIS AND SAFETY CHECK OF THE FAULT OF LOW SPEED HEAVY LOADED GEAR

运用振动监测进行故障诊断与分析,在多轴式齿轮传动、啮合频率较多且相差较大的情况下,判断出低速重载齿轮的故障,并通过对啮合频率的分析,得出了如何判断齿轮严重断齿数目的方法;同时,通过对齿轮箱工作安全系数的计算进行了承载能力的校核,提出了低速重载齿轮故障诊断和齿轮箱选型的建议。

This paper uses vibration monitoring in the fault diagnosis and analysis to judge the fault of low speed heavy loaded gear in the conditions of multi-spindle gear transmission, more meshing frequency and a large difference in meshing frequency,and draws a conclusion on how to determine the number of serious broken tooth of the gear based on the analysis of meshing frequency.At the same time,the bearing capacity is checked by calculating the safety factors of the gear box,and some suggestions are put forward on the fault diagnosis of low speed heavy loaded gear and the selection of gear box.
