Root stresses of thin − rimmed helical gears with symmetric and asymmetric web arrangement of helix angle ≠ も = 10 °and 20 °, which were meshed with solid helical gear, were measured from the beginning ofengagement to the end ofthe engagement by using the strain gauge method . The changes ofroot stresses from the beginning ofengagement to the end ofengagement were examined . The effects ofhelix angle , rim thickness , web thickness and web structure on the root stresses, the maximum root stress

... and the mes 血ing position , where the maximum root stress ( worst loading position )occurs , were clari ∬ed . Furthermore , the obtained results were compared with the results of the solid helical
