“…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.…”

Dynamic loads are inevitably generated during the operation of rotating machinery. In situ monitoring the dynamic loads is of great significance for assessing shafting health. Triboelectric nanogenerator (TENG) is sensitive to motion but not suitable for load monitoring, while piezoelectric nanogenerator (PENG) is just the opposite. Therefore, the combination of the two can complement each other. From this, a dynamic load monitoring smart bearing (DLMSB) integrated with TENG and PENG is proposed. The specially designed TENG can produce an “M‐waveform”, which can be used to extract rotation frequency and distinguish the quadrant of the rotor. Meanwhile, applying PENG to capture the load condition of the bearing, and referring to the main frequency of M‐waveform, it is convenient to obtain the dynamic loads of shafting. Furthermore, a real‐time monitoring system is developed, which can realize not only real‐time monitoring of the rotation speed and dynamic loads magnitude but also the quadrant discriminating of dynamic loads. The results have shown that the monitoring error for dynamic loads is 3 N or 5.5%, and the accuracy rate for determining the quadrant of the dynamic loads can reach 93%. This study provides a novel approach for the in situ monitoring of mechanical operating status via nanogenerators.
