VDI 2736 Blatt 1-4.: Thermoplastic Gear Wheels, Verein Deutscher Ingenieure, Düsseldorf, Germany (2016)ĪGMA 920-B15.: Materials for plastic Gears, American Gear Manufacturers Association (2020) Analysis of the failure mechanisms shows that crack progression the tooth root is slower in gears produced of HDPE with beech fibers because of the higher tensile strength of the material compared HDPE with spruce fibers. From a perspective of flank wear analysis, beech fibers were found to be more wear-resistant than spruce fibers in the same polymer matrix. Results shows longer durability performance of HDPE reinforced with beech compared to HDPE with spruce fibers in average for 15%. ![]() The aim of the study was to determine lifetime cycles until the failure of wood polymer composite gears, generated temperatures in the gear pair contact and fundamental flank wear characteristics of various composites with two natural sort of wood fibers in the case of gears. Wood polymer composite gear was mated with steel pinion. In this research, lifetime tests of wood polymer composite gears were carried out using High Density Polyethylene (HDPE) reinforced with 20% of spruce fibers and the same polymer matrix reinforced with 20% of beech fibers. To integrate these materials into a real mechanical part such as gears, it is necessary to evaluate their mechanical, thermal and tribological operating performances. With the increasing need to recycle already used materials, there have been tendencies to use bio-based materials that would enable recycling and reuse in secondary fewer demanding parts or assemblies. It is necessary to highlight the various polymer materials and fibres options used for gears for a specific purpose to meet the requirements of a specific drive train application. A variety of research work on the field of polymer gears have become very significative during the last decade.
