Comparison between 3D FEM and Standard ISO Tooth Root Stresses

The paper deals with the discussion how nominal spur tooth root stress of thin-rimmed gear determ ined in accordance with the standard [SO 6336-3:2006, method B, agrees with the results of the 3D FEM stress analysis. The procedure proposed by standard ISO for the tooth root stress calculation doesn't identify the stress behaviour related to mutual affects of characteristic thin-rimmed gear geometrical parameters. Therefore, the 3D FEM analysis of tooth root stress has been performed for gear structures with middle and offset web with various rim and web thickness. The rim thickness has covered and slightly overcome the backup ratio defined by [SO procedure, while the web thickness has covered the ran ge of practical interest.
