Effect of Mating Metal Gear Surface Texture on the Polymer Gear Surface Temperature
Materials Today: Proceedings, 2015Abstract Gear performance is significantly influenced by the interacting surface conditions; however, very few attempts have been made to understand the effect of mating surface condition. In this work, injection molded polypropylene gears were meshed with machined metal gears having different surface conditions.

Proceedings of the Institution of Mechanical Engineers, Part L: Journal of Materials: Design and Applications, 2021
The material of the mating gear influences the fatigue life of polymer gears. The bending fatigue characteristics of polyamide 66 asymmetric gears (34°/20° and 20°/34°) corresponding to steel–polymer and polymer–polymer material combinations were investigated.

ABSTRACTThis paper developed a new and simple approach to model polymer draft gears. Two types of polymer draft gears were modelled and compared with experimental data. Impact characteristics, in-train characteristics and frequency responses of these polymer draft gears were studied and compared with those of a friction draft gear.

The wear behaviour of polymer composite gears
Journal of Synthetic Lubrication, 1996AbstractIn order to examine the wear of polymer composite gears, a test facility has been developed which has enabled the wear of gear trains to be measured continuously during gear operation. Brief details of the method are given. The purpose of this paper is to report some of the results obtained from this facility and, in particular, to discuss the ...
