摘　　要：ANSI/AGMA 2003-B97是现行弧齿锥齿轮领域中应用广泛的一个弯曲应力校核标准。对其弯曲强度校核计算公式进行分析,对关键参数进行修正,以解决弯曲强度校核安全裕度不足的问题,并通过有限元接触分析对其进行验证。基于修正后的弯曲强度校核标准,开发出弧齿锥齿轮强度校核软件,同时给出齿面优化设计方案。提出的方法可提高目前齿面弯曲强度校核计算的精度和效率。The ANSI/AGMA 2003-B97 is a widely used bending stress checking standard for spiral bevel gears.The calculation formula of bending strength checking is carried out,the key parameters are modified,the problem of insufficient safety margin of bending strength checking solved,and this method is verified by finite element contact analysis.Based on the modified bending strength checking standard,the strength checking software of spiral bevel gear is developed,and the optimal design scheme of tooth surface is given.The proposed method can improve the accuracy and efficiency of tooth surface bending strength checking calculation.
