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.

The significance of polymer gears to transmit power and motion is increasing continuously due to their inherent characteristics. Polymer gears have established themselves as attractive alternatives to traditional metal gears in plethora applications. They are light in weight, have lower inertia, and run noiseless than their metal counterparts. This article presents a comprehensive review of the research on polymer spur gears operating under low (0–8 Nm) and moderate (>8 and ≤17 Nm) loading conditions. Different polymers and polymer composites used till date for the fabrication of such gears are included along with different operating conditions. Various design features of polymer gears and tooth modification techniques for the improvement of the performance and durability of these gears have also been included in this review. The aspects of the modeling and simulation studies of the polymer gears are also emphasized in this paper for completeness of the review. The concept of hybrid gears is discussed along with their tribological properties. Various methods of manufacturing of polymer gears and their failure modes are discussed so as to make the article useful for researchers.

“…16 Accordingly, the previously introduced methods without considering viscoelastic properties are unsuitable for nylon gears. Hiltcher et al, 17 Letzelter et al, 18,19 and Cathelin et al [20][21][22] applied the thermoviscoelastic (TVE) material models that describe the rate dependence and the temperature dependence for the contact analysis of polyamide 66 (PA66) gears and validated them experimentally. C ̌erne et al 23 simulated the meshing temperature of POM gears by considering the strain rate sensitivity of POM while Doll 24 considered the hysteretic dissipation within PEEK gears.…”

This study concerns a numerical analysis of the meshing temperature for a multicomponent nylon gear by incorporating typical viscoelastic responses of polymers. Firstly, the generalized Maxwell model parameters were calibrated by the dynamic mechanical analysis to capture the viscoelasticity of polyamide 66. Next, the finite element model predicting the meshing temperature was established, including the heat generation analysis model, which calculates the generation of the frictional and hysteretic heat, and the heat propagation analysis model, which simulates the heat transmission. Different material models were used for polyamide 66 to investigate the influences of temperature dependence, strain rate dependence, and hysteretic effect. The effect of the iteration sequence on the meshing temperature calculation was also analyzed, i.e., how the heat generation should be updated as the loading cycles increase. A reasonable iteration scheme was determined by balancing the computational precision and consumption. It is noteworthy that the evolution of the ambient temperature around the gear and the worm within the housing was also considered. Finally, the accuracy of such meshing temperature analysis was validated on a self-developed gear test rig, in terms of the peak temperature evolution on the gear side surface. The experimental results and the simulation with the ambient temperature correction match well and the maximum error is 5 °C.
