    摘要:

    齿轮箱作为机械设备中的关键部件,其安全服役性能评估及寿命预测环节是非常重要的。因此,设计了一套基于冲击脉冲法的齿轮箱轴承故障检测系统。探究了检测系统的设计原理,并进行硬件选型(如NI四通道数据采集卡、加速度传感器等)、软件模块设计(如数据采集模块、分析和处理模块等)。根据车间现场条件制定齿轮箱轴承跑合检测试验方案,分别测试了不同返修级别(4级修、5级修)的齿轮箱轴承。对检测结果进行分析,表明:所设计的齿轮箱轴承检测系统能够实现对不同返修级别的齿轮箱轴承系统进行故障状态甄别,具有较高的稳定性,可为初步判定不同返修级别的齿轮箱轴承中磨损程度或故障状态提供数据支撑。

    Abstract:

    Gearbox considered as the key components of machinery equipment, the link of security service performance evaluation and life prediction are very important. Therefore, a set of gear box bearing fault detection system based on shock pulse method is designed. First of all, the design principle of testing system was explored, and hardware selection (such as National Instrument(NI) fourchannel data acquisition card, acceleration sensor, etc.) and software module design (such as data acquisition module, analysis and processing module, etc.) were also completed. Secondly, according to the workshop site conditions, the testing plan for gearbox bearing runningin was finished, and the different level of repair (level 4 and level 5) gearbox bearing were tested. The analysis of the test results shows that the gear box bearing detection system designed can identify the fault status of the gear box bearing system with different repair levels, and has a high stability. It can provide data support for the initial judgment of the wear degree or failure state of the gear box bearing with different repair levels.
