摘　　要：针对直齿锥齿轮设计和制造过程中大端齿厚计算存在误差的问题,提出一种精确计算直齿锥齿轮大端齿厚的计算方法。从直齿锥齿轮齿面和大端齿廓的形成原理出发,推导大端球面渐开线的表达式。在此基础上,给出大端齿厚精确计算方法。计算实例表明,该计算方法比传统当量齿轮计算方法更为精确,为提高直齿锥齿轮加工精度奠定了理论基础。For the problems of the calculation error about big end tooth thickness on the process of design and manufacture of straight bevel gear,the precision calculation method of tooth thickness of stragiht bevel gear big end is put forward. From the generation principle of straight bevel gear tooth surface and big end tooth profile,the expression of big end spherical involute is given. On the basis,the precision calculation method of big end tooth profile is given. The calculation example shows that the proposed calculation method is more accurate than the traditional calculation method,and lay the theoretical support for improving the machining precision of straight bevel gear.
