摘要
采用冻结切片三维光弹试验方法,对双渐开线齿轮的弯曲应力进行研究,试验结果与有限元计算相吻合;在高频疲劳强度试验机上完成软、硬齿面轮齿的弯曲疲劳强度试验,结果表明轮齿的断裂位于齿根处30°与40°之间,当齿厚变位系数为0.08时,双渐开线齿轮的弯曲强度大约提高了16%。
Bending stress of tooth of DIGLST (Double involute gear with ladder-shaped teeth ) is investigated by three dimensional freezing slice photoelastic experiment, the result is mostly alike in comparison with one by FEM. The experiment of soft -tooth gear and hard-tooth gear is carried on high frequency fatigue strength te ster, the crack type indicated that location of crack initiation is between 30 °and 40°.While the coefficient of tooth thickness is 0.08, the magnitude of decreased stress is about 15% in comparison with traditional involute gear.
