摘要
圆弧齿线(CATT)圆柱齿轮齿根应力的计算与普通渐开线不同.根据第四强度理论,作者建立了一个力学模型,并用此模型计算了CATT齿轮的齿形系数,对齿根应力沿齿线的变化作了分析.
Circular-arc-tooth-trace (CATT) cylinder gear differs from straight-cut cylinder gear in calculation of the gear tooth bending stress. Based on the fourth strength theory, we established a dynamical model for calculating the tooth stress of CATT cylinder gear. We applied the model to calculation of the coefficient of the gear shape and analysis of the stress distribution along the length of the tooth in the root fillet.
