Root stresses of thin-rimmed helical gears with web arrangement were measured, and then effects of rim and web thicknesses and web structure on root stress in meshing process, the maximum root stress and the worst meshing position were determined. Bending fatigue tests were carried out for the thin-rimmed helical gear meshed at the worst meshing position, and then S-N curves and bending fatigue limit loads were obtained. The main results obtained are summarized as follows. (1)Th worst meshing posiition of thin-rimmed helical gear is near the outer point of single tooth pair contact in the case of of small helix angle and is the backward position a little from the pitch point of the end of face width of leading side in the case of large helix angle. (2) The bending fatigue strength of thin-rimmed helical gear has not a influence of web position in the case of thin rim and web, and the effect of helix angle is also considerably small compared with the case of root stress.

对辐板布置的薄轮缘斜齿轮齿根应力进行了测量，确定了啮合过程中轮缘厚度、辐板厚度和辐板结构对齿根应力的影响，以及最大齿根应力和最差啮合位置。对最不利啮合位置的薄壁斜齿轮进行了弯曲疲劳试验，得到了S-N曲线和弯曲疲劳极限载荷。所得主要结果概括如下。(1)Th在小螺旋角情况下，薄边斜齿轮的最坏啮合位置在单齿对接触的外点附近;在大螺旋角情况下，薄边斜齿轮的最坏啮合位置在距齿宽前端的节点稍靠后的位置。(2)薄轮缘斜齿轮的弯曲疲劳强度在轮缘薄、辐板薄的情况下，辐板位置对弯曲疲劳强度没有影响，螺旋角的影响也比齿根应力的影响小得多。
