运输机减速器的润滑磨损监测与故障诊断

 长壁工作面运输机是综合机械化采煤工作面的关键设备，如何保证其连续安全运转一直成为备受关注的课题。本文介绍了基于油液分析与铁谱技术，在线监测运输机减速器的润滑磨损状态、不停机预知诊断故障的实验分析研究过程。考察了油液分析取样的技术理论基础；采用原子发射光谱仪测试在用润滑油中的添加剂元素、污染元素、磨损元素的浓度，振荡球式粘度计测试在用润滑油的运动粘度，分析式铁谱仪制成铁谱载片、在铁谱显微镜下观察分析在用润滑油中载有的磨损磨粒，并测得圆锥滚子轴承、螺旋锥齿轮、圆柱正齿轮等的典型磨粒图谱。研究分析测试实验结果、阐述润滑磨损机理，给减速器的润滑磨损状态及故障作出诊断，同时提出使用、维修、管理等方面的建议。最后对技术经济效益，以及普及应用作出评价。

Lubrication and Abrasion Monitoring and Fault Diagnosis of Gearbox Applied in Scraper Conveyor

In order to improve the production safety reliability of the scraper conveyor in the fully mechanized coal mining face,the paper introduced the lubrication and abrasion fault monitoring and diagnosis technology method of the gearbox applied in the face scraper conveyor.Base on the oil liquid analysis and iron spectrum technology,a prediction of the fault diagnosis with no stop operation could be conducted on the on-line monitoring and measuring of the lubrication and abrasion status.The paper summarized the...
