Tooth bending strength of gears with a progressive curved path of contactZorko, Damijan ; Duhovnik, Jože, 1948- ; Tavčar, Jože, 1966-The article presents a comprehensive study on the tooth bending strength of spur gears with a progressive curved path of contact, or so-called S-gears. Systematic gear meshing simulations were ... conducted to study the effects of S-gear geometry parameters on tooth bending strength. Different S-gear geometries were analysed in a systematically organized manner, and a comparison was made against a standard 20° pressure angle involute shape. Furthermore, different material combinations, e.g. polymer/polymer, steel/polymer, and steel/steel, of both drive and driven gear were analysed within a meaningful range of loads. The gear profile shape, material combination of the drive and the driven gear, and the transmitted load were found as the main parameters affecting gear tooth bending stress. Complex, non-linear relations between the recognized effects and the corresponding root stress were observed. Based on the numerical results, a shape factor, which considers the above-mentioned effects, was introduced, and a model for root strength control of S-gears was proposed and verified employing the finite element method (FEM).Vir: Journal of computational design and engineering. - ISSN 2288-4300 (Vol. 8, iss. 4, Aug. 2021, str. 1037-1058)Vrsta gradiva - članek, sestavni del ; neleposlovje za odrasleLeto - 2021Jezik - angleškiCOBISS.SI-ID - 73988099
