齿轮磨损是许多应用中的一个关键退化过程，其监测对于确保机器的安全运行非常重要。该案例研究提出了一种获取全面、高分辨率磨损信息以监测齿轮磨损演变的新颖方法。这是通过结合成型方法和基于非接触式成像的二维和三维测量来实现的，无需拆卸齿轮箱和拔齿。在润滑耐久性测试期间，采用光学和激光扫描共焦显微镜和图像处理工具来量化齿轮齿上的表面粗糙度、磨损严重程度和磨损深度。此外，还对两种主要磨损机制（磨粒磨损和疲劳点蚀）的进展进行了详细的定性分析，同时对所提出的方法提供的诊断能力进行了评估。本案例研究中提供的关于齿轮磨损的见解也为齿轮状态监测领域的研究人员和工程师提供了宝贵的指导。此外，所提出的磨损分析技术可用于表征和理解其他条件和齿轮传动装置中的磨损现象。
Gear wear is a critical degradation process in many applications and its monitoring is important to ensure safe operation of machines. The case study presents a novel approach to obtain comprehensive and high-resolution wear information for monitoring the evolution of gear wear. This is achieved through the combination of a moulding method and non-contact imaging-based measurements in two- and three-dimensions and without gearbox disassembly and tooth removal. Optical and laser scanning confocal microscopy and image processing tools were employed to provide quantification of surface roughness, wear severity and wear depth on gear teeth during a lubricated endurance test. Also, a detailed qualitative analysis on the progression of the two main wear mechanisms (abrasive wear and fatigue pitting) was provided, alongside an evaluation of the diagnostic capabilities offered by the proposed methodology. The insights on gear wear offered in this case study also represent a valuable guideline for researchers and engineers in the field of gear condition monitoring. Moreover, the proposed wear analysis technique can be used to characterise and understand wear phenomena in other conditions and geared transmissions.
