20.500.12556/DKUM-87525 Computational model for analysing the tooth deflection of polymer gears A computational model for analysing the tooth deflection of polymer gears is presented in this paper. Because polymer gears have less stiffness compared to metal gears, the proposed approach considers a comprehensive analysis to determine the most suitable numerical model, i.e., the number of teeth that should be modelled for a given gear’s geometry and material. The developed computational model has been evaluated using a spur gear pair, where the pinion made of POM was meshed with a support gear made of steel. Material properties were assigned with linear elastic characteristics for the gear, while the pinion was characterised by hyperelastic properties using POM material. Furthermore, a nonlubricated frictional contact between the gear and pinion was considered in the numerical computations. The computational results that were obtained were compared to the empirical results according to VDI 2736 guidelines. Here, the computational approach showed more accurate results due to the hyperelastic material characteristics of POM and the simulation of multiple teeth meshing. However, VDI 2736 calculation showed comparability with the computational results, with a slightly larger deviation at higher loads. In this respect, the proposed computational approach is more suitable for analysing the tooth deflection of polymer gears under higher loads. polymer gears tooth deflection computational modelling polimerni zobniki odklon zoba poves zoba računalniško modeliranje true false true MDPI Angleški jezik Slovenski jezik https://www.mdpi.com/journal/polymers © 2024 by the authors Članek v reviji 2024-03-19 15:50:43 2024-03-19 15:50:44 2025-07-22 11:27:18 0000-00-00 00:00:00 2024 0 0 12 str. iss. 5, [article no.] 677 Vol. 16 March 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2024-01-26 2024-02-29 2024-03-02 621.833:678.7 187843075 10.3390/polym16050677 2073-4360 polymers-16-00677.pdf polymers-16-00677.pdf 1 8F1A37EA0559216320A36385B02B26F0 7011d33486be041ea5b335bced49d0507ad900b89602322a3ef07f7cd736fe36 5cbbd222-e600-11ee-8d81-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=177095 https://www.mdpi.com/2073-4360/16/5/677 0 62fad6cf-e600-11ee-8d81-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=177096 Fakulteta za strojništvo 0 0 0
