1北京理工大学珠海学院 2020 届本科生毕业设计（论文）齿轮常见故障以及诊断技术应用分析摘 要齿轮是生产设备中必不可少的传输动力元件，齿轮的正常工作不仅可以保证安全生产的进行，还可以提高生产效率。齿轮在工业、农业、航天业、军事等方面都有广泛的应用，某种程度上来说齿轮是世界上参与份量最多的机械元件。另一方面，齿轮的耐久性不足导致其经常发生故障，如果使用不当发现故障不及时，就会阻扰设备的正常运行。因此，了解齿轮常见故障以及研究齿轮故障诊断技术是设备状态保障的基础和关键，只有在故障发生早期就精准诊断，及时维修，才可以阻止故障的蔓延，避免财产的损失和人员伤亡。本文主要对齿轮常见故障，如齿的断裂、齿面磨损、齿面腐蚀等故障现象的原理进行分析，然后将目前生产中常用的故障诊断技术进行分析，研究其优势以及劣势，提出改进方案。关键字：齿轮故障类型 诊断 油液分析 振动信号分析2北京理工大学珠海学院 2020 届本科生毕业设计（论文）Analysis of common faults of gears and application of diagnostic techniquesAbstractGear is an indispensable transmission power component in production equipment, the normal operation of gear can not only ensure the safety of production, but also improve production efficiency. Gears are widely used in industry, agriculture, aerospace, military and other fields. To some extent, gears are the most heavily involved mechanical components in the world. On the other hand, the insufficient durability of the gear often leads to its failure, if the improper use of the fault is not found in time, will hinder the normal operation of the equipment. Therefore, it is the basis and key of equipment condition guarantee to understand the common faults of gears and study the fault diagnosis technology of gears. Only in the early stage of fault diagnosis and timely maintenance can the spread of faults be stopped and property losses and casualties be avoided. This paper mainly analyzes the principle of common faults of gear, ...
