20.500.12556/RUL-138439 An investigation on the potential of bio-based polymers for use in polymer gear transmissions The potential for replacing the fossil-based Polyoxymethylene (POM) and Polyamide 66 (PA 66) in polymer gear applications with a bio-based Polyamide 6.10 (PA 6.10) was studied and is presented in the article. The use of bio-based plastics is increasing but mostly in undemanding applications like packaging. High-performance plastics are needed in polymer gear transmissions since their operational conditions are far more severe. The potential of bio-based PA 6.10 was studied by means of gear lifespan testing. Additional insights into the process of polymer gear meshing were garnered by simulating all the tested cases with a FEM model of meshing gears. Test gears were manufactured from commercially available materials, making the results useful for gear designers. Encouraging results were observed since the PA 6.10 gears exhibited a 3.5-times longer lifespan than POM gears and a 10-times longer lifespan than PA 66 gears when tested under identical test conditions. The results indicate great potential for replacing fossil-based plastics in polymer gear applications with bio-based polymer materials. The fatigue strength, coefficient of friction, and wear coefficient were determined and compared for the tested materials, facilitating the reliable design of polymer gears. biopolymers gears testing simulations wear fatigue biopolimeri zobniki testiranje simulacije obraba utrujanje true false true Angleški jezik Slovenski jezik Članek v reviji 2022-07-20 15:04:30 2022-07-20 15:04:35 2022-09-15 04:16:45 0000-00-00 00:00:00 2021 0 0 13 str.
