摘　　要：固定弦齿厚、公法线长度与跨棒距是描述齿轮齿厚的三种参数,本文就这三种齿厚参数的特点及适用范围进行了讨论,通过分析三种参数的微量关系,推导出它们之间相互转换的计算列式,得出了三个常见压力角条件下三种齿厚参数的微量关系图,并给出了微量关系图的具体应用示例。基于三种齿厚参数微量转换关系列式及微量关系图,可在已知一种齿厚参数微量的条件下,高效地得到另外两种齿厚参数的微量值,为工程应用提供了便利。Constant chord height,base tangent length and the span of rod are the parameters that describe the tooth thickness of the gear.This article discusses the characteristics and application scope of three tooth thickness parameters and analyzes the increment relationship of these parameters.The calculation formula for the conversion among the three parameters’increment was derived,the relationship of three tooth thickness parameters under three common pressure angles were obtained,and application examples were given.Based on the conversion relationship of the three tooth thickness parameters,the increments of the other two tooth thickness parameters can be easily obtained when one of the tooth thickness parameters is given,which will effectively faclitate engineering applications.
