“…A method for analyzing wear particles of gear pump components was presented by Dhote and Khond [12]. In turn, Clarke et al [8] compared ultrasonic load measurements on the bearing of a high-speed shaft of a wind turbine gearbox with the results of a static multi-object simulation and found that the measurements made under established operating conditions agreed well with the adopted model. Feng et al [19,20] developed a cyclostationary pitting monitoring indicator that can accurately assess the degradation status of the system.…”

The article provides a discussion on the results of the original studies of a power transmission system of a mining scraper conveyor coupled with an innovative highly flexible clutch, conducted in operating conditions. The research consisted in establishing the static characteristics of the highly flexible clutch in question, determining the torsional vibrations of the said highly flexible clutch and the vibrations of the transmission housings at a test rig, verifying if the coupling between the innovative flexible clutch and a typical scraper conveyor drive unit was correct, and testing durability of individual components of the highly flexible clutch. Following the aforementioned tests, one can distinguish three phases of its operation: initial, main, and final – all differing in terms of flexibility. Furthermore, upon increasing the flexibility of the metal clutch, a significant decline in the root mean square (RMS) values of linear vibration accelerations was observed compared to the blocked condition of the clutch.

“…Additionally, the gearbox bearing absorbs and dampens shock and vibration within the gearbox [60]. Due to the long-term operation of bearings in harsh environmental conditions, gearbox bearings are exposed to various forms of wear, and the most common significant forms of wear include fatigue wear, adhesive wear, and surface wear [19,61,62]. Figure 4 shows common forms of bearing wear.…”

With the significant penetration of wind generation, wind turbines require higher and higher lubrication performance for bearings. To improve the lubrication performance of wind power bearings, this study takes wind power bearings as the research object and comprehensively analyzes the wear forms of wind power bearings as well as intelligent lubrication methods. Firstly, the main roles and wear forms of wind turbine bearings are sorted out and analyzed. Secondly, the common lubrication problems of wind power bearings are analyzed from the bearing grease selection, lubrication mode, and lubrication status, highlighting the important influence of lubrication on bearings. Thirdly, the wind turbine bearing wisdom lubrication method research and organization, mainly including the wind power generation bearing lubrication materials, lubrication devices and monitoring methods, and other issues of research and analysis. Finally, current challenges and future development directions are summarized, which are designed to provide theoretical reference and technical support for the related research and engineering practice in the field of wind power engineering.
