20.500.12556/RUL-125686 Thermo-mechanical modeling of polymer spur gears with experimental validation using high-speed infrared thermography The presented work is focused on the development of a comprehensive thermo-mechanical model for predicting the temperature rise in thermoplastic polymer spur gears with any desired profile geometry while running. The specific constitutional behavior of thermoplastics influences the gear-meshing pattern, which can deviate substantially from ideal gear meshing, as typically exhibited by metal gears in moderate-loading conditions. Taking this aspect into account is of paramount importance if realistic temperature-rise predictions are to be made. The thermal response of the considered gear pair is studied thoroughly from both the analytical and experimental standpoints. Good agreement was found between the results of the model and the experimental measurements performed using a high-speed thermal imaging infrared camera, although it was also observed that the real-life temperature rise can increase noticeably if large geometric tolerance deviations from the ideal profile geometry are present. The presented experimental approach also offers the possibility to observe the temperature rise inside and outside the meshing cycle. polymer gears thermal analysis sliding friction contact mechanics IR thermography polimerni zobniki termične analize drsno trenje kontaktna mehanika IR termografija true false true Angleški jezik Slovenski jezik Članek v reviji 2021-04-01 21:20:07 2021-04-01 21:20:10 2022-09-05 03:52:04 0000-00-00 00:00:00 2020 0 0 22 str. art. 103734 Vol. 146 Apr. 2020 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 621.833:678(045) 0094-114X 10.1016/j.mechmachtheory.2019.103734 17011483 5762311 RAZ_Cerne_Borut_2020.pdf RAZ_Cerne_Borut_2020.pdf 1 DA6E138A68069B36A465D88A1B1CFF84 c2682f99eebba612bad02f26a5c01d9cfe89e3cb1cac8ef5ad5d5060a4816377 c4ad84f9-a1bb-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=141529 https://www.sciencedirect.com/science/article/pii/S0094114X19323407 1 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=141528 Fakulteta za strojništvo 0 0 0
