20.500.12556/RUL-143344 Comparison of load-carrying capacity, wear, and resource of metal-polymer corrected spur gears with a gear made of polyamides РА6 or PA6+30CF Primerjava nosilnosti, obrabe in obstojnosti korigiranih kovinsko-polimernih čelnih zobniških dvojic z večjim zobnikom iz poliamida PA6 oz. PA6+30CF Based on the developed calculation research method of metal-polymer gears the analysis of the influence of height and angular correction of engagement of spur gears on load-carrying capacity, linear teeth wear, and resources is carried out. Gears with a pinion made of carbon steel 0.45%C and a gear made of basic polyamide PA6 or carbon fibre composite PA6 + 30CF were investigated. Quantitative and qualitative patterns of influence of both types of correction, changes in the initial teeth profile due to wear, mating conditions on the load carrying capacity, teeth linear wear, and service life of investigated metal-polymer gears have been established. Profile correction causes a decrease in the contact pressure in the engagement by different amounts during the meshing cycle. They are most significantly reduced in the input area of two-pair engagement. It was found that when using PA6 + 30CF, the maximum contact pressures are about 1.29 times higher than with PA6 at all values of the shift coefficients, regardless of its type. The tooth linear wear has different values during the meshing cycle depending on the shift coefficients and parity of engagement. The resource first increases with increasing the shift coefficients, reaching their optimum, and then decreases again. Regularities of this influence for each type of correction of engagement are established. Metal-polymer gears with a gear made of PA6 + 30CF will have a significantly higher service life than with a gear made of PA6. metal-polymer spur gears height and angular correction of engagement polyamides PA6 and PA6 30CF maximum contact pressures linear teeth wear resource kovinsko-polimerna čelna zobniška dvojica korektura ubirne višine in kota poliamida PA6 in PA6 + 30CF maksimalni kontaktni tlak linearna obraba zob obstojnost zobnikov true false true Angleški jezik Slovenski jezik Članek v reviji 2022-12-15 10:01:15 2022-12-15 10:01:19 2022-12-16 03:29:40 0000-00-00 00:00:00 2022 0 0 Str. 713-721 no. 11 Vol. 68 Nov. 2022 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2022-11-01 539.4:621.8 0039-2480 10.5545/sv-jme.2022.242 133966083 Chernets...-Comparison_of_Load-Carrying_Capacity,_Wear,_and_Resource_of_Metal-Polymer_Corrected_Spur_Gears_with_a_Gear_Made_of_Polyamides_РА6_or_PA6+30CF.pdf Chernets...-Comparison_of_Load-Carrying_Capacity,_Wear,_and_Resource_of_Metal-Polymer_Corrected_Spur_Gears_with_a_Gear_Made_of_Polyamides_РА6_or_PA6+30CF.pdf 1 5C87E7BF898183185F4B0DEC359F1AA4 d02bac7c4bb48807a8854f85ff557e7556a684f39b57c8f7c9c8ed73d9711f54 32ec3bf1-7c57-11ed-9c94-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=164983 https://www.sv-jme.eu/sl/article/comparison-of-load-carrying-capacity-wear-and-resource-of-metal-polymer-corrected-spur-gears-with-a-gear-made-of-polyamides-%d1%80%d0%b06-or-pa630cf/ 1 df6d2d58-7c56-11ed-9c94-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=164982 Fakulteta za strojništvo Strojniški vestnik 0 0 0
