Root stresses in meshing process from the beginning of engagement to the end of engagement of thin-rimmed helical gears with symmetric and asymmetric web arrangement of helix angle helix angle β_0=10 and 30°, which were meshed with solid helical gears, were measured by means of the strain gage method. The changes of root stresses in the meshing process, the maximum root stress, the position of the maximum root stress and the worst meshing position (the meshing position where the maximum root stress occurs) were examined, and then the effects of rim and web thickness, web structure, and helix angle on root stresses were determined by comparing with the results of β_0=20°. Furthermore, the results obtained were compared with those of solid helical gears.
