Sažetak
The affect of a spur thin-rimmed gear structure upon tooth root stress has been analysed for a gear without web and with middle and offset web. To bring into line with the proposal of standard ISO, method B for tooth root stress calculation where the rim thickness factor is used for nominal stress correction of thin-rimmed gear, the ratio of tooth root stress for thin-rimmed and a solid gear, has been established based upon the 3D FEM calculations. Unlike for the case of standard ISO tooth root stress calculation, the obtained stresses have allowed the insight into the influence of actual gear structure on the tooth root stress, they have pointed to the differences between analytical 2D ISO and 3D FEM approach, and have aimed the possibilities for tooth root stress minimisation.
