“…It was shown that POM gears may experience this phenomenon when subjected to loads exceeding 10 Nm at an ambient temperature of approximately 25 • C [18,19]. Apart from abrasive wear, thermal wear is the main wear component for a POM/steel pairing [20]. The wear rate is similar to that of a POM/POM combination [18].…”

As an integral part of a machine, gears are subject to wear, which is influenced by a number of factors. For polymer gears in particular, the uncertainties due to wear are high. These uncertainties outweigh the advantages of polymer gears, such as lower inertia. Improved condition monitoring, for example, with better data acquisition, could reduce these uncertainties and is therefore of great interest. This study addresses the challenges of condition monitoring in polymer gears by investigating the integration of sensors directly onto the gears for improved sensitivity. A compact sensor module mounted on a polymer gear is presented to demonstrate the benefits of integrated sensors. The research compares the effectiveness of integrated acceleration and temperature sensors with state of the art external methods. The results show that the in situ sensor module (ISM) provides reliable measurements for condition monitoring with integrated sensors. A comparative analysis with methods based on the current state of research highlights the increased sensitivity of condition monitoring based on the ISM acceleration sensors compared to traditional bearing block sensors. This increased sensitivity shows a clear advantage of integrated sensors over established methods. The temperature curve of the integrated sensors is sensitive to abrasive wear and gear failure, indicating the wider potential of integrated temperature sensors. In conclusion, this research lays the foundation for advanced condition monitoring using integrated sensors in polymer gears. The knowledge gained contributes to optimising gear applications, promoting cost-effectiveness and aligning with the principles of the Internet of Things and Industry 4.0.

“…Furthermore, it was observed that a plain medium carbon steel (DIN C56E2) showed better surface fatigue resistance than a low alloy high carbon steel (DIN 100Cr6) at similar surface hardness levels if surface induction hardening is applied on the former. Correlation between the tribological behavior of polymer-steel contacts and the performance of real-scale gears was reported [452]. The results showed that tests at 50 °C in slide-roll ratio (SRR)-variable model tribotests can predict the SRR-dependent wear mechanisms along the meshing path in real gears, while the 80 °C tests are too severe, leading to thermal overload.…”

“…In contrast to conventional pin-on-disk tests with pure sliding for tribological test, the variation of slip-roll-ratio (SRR) in the model tribological test mimic different wear mechanisms of real scale gear tests. 168 However, for gear design calculations, the value of wear coefficient of polymers should be obtained from real-scale gear tests. 169 Ghelloudj et al 67 developed a new engineering model to define the evolution of tooth flank wear (wear profile) as a function of number of cycles of driving wheel, the pinion.…”

In this research work an extensive review on use of advance materials and performance of polymer gears. Further, literature on polymer gears has been divided into four divisions based on the type of gear material, performance characteristic, modifications, and manufacturing techniques. Materials like polyamide and acetal and their composites are focused due to their huge application quotient. Use of in total six grades that is, PA6, PA66, PA12, PA46, PA618, and PA645 as gear material have been identified. Use of glass and carbon fiber reinforcements in PA gears with varying percentage in a range of 20%–35% and 15%–30%, respectively have been observed. Failure and performance characteristics such as wear, thermal, fatigue, load, transmission, and operational have been illustrated and described in detail. Research studies to improve thermal performance of plastic gears by modifying gear tooth and its profile has also been discussed along with their effects. Application of advance manufacturing technique such as 3D printed additive manufacturing in producing plastic gears is also talked over in this article. This compiled review work aims to assist researchers in selection of plastic gear material and to explore various factors and parameters affecting the failure behavior and performance of plastic gears.
