| Popis: | Purpose of this study is the consideration of loadi ng and contact problems encountered at rotating mac hine elements and especially at toothed gears. The later are some of the most commonly used mechanical components for rotary motion and power transmission. This fact proves the necessity for improved reliability and enhanced service life, which requir e precise and clear knowledge of the stress field a t gear tooth. This study investigates the maximum allowabl e stresses occurring during spur gear tooth meshing computed using Niemann’s formulas at Highest Point of Single Tooth Contact (HPSTC). Gear material, module, power rating and number of teeth are consid ered as variable parameters. Furthermore, the maximum allowable stresses for maximum power transmission conditions are considered keeping the other parameters constant. After the application of Niema nn’s formulas to both loading cases, the derived re sults are compared to the respective estimations of Finit e Element Method (FEM) using ANSYS software. Comparison of the results derived from Niemann’s formulas and FEM show that deviations between the two methods are kept at low level for both loading cases independently of the applied power (either ra ndom or maximum) and the respective tangential load. |
