For cutting the composite lock gear with unequal tooth thickness , a study is made on the design method of gear sharper cutter with nonstandard parameter involute tooth profile and noninvolute tooth profile . the cutter tooth arrangement , the choice of teeth number of the cutter and the basic method of cutter design are discussed ; and a new method of choosing deflection factor by using limited area is presented . and the curve of relationship between rear angle on tooth crest and helical angle on tooth side of the cutter is given so as to give a basis for the gear sharper cutter to choose its parameters . to design nonstandard gear sharper cutter by adopting the method mentioned above will simplify the calculation and will increase the efficiency of design 研究加工不等齿厚的非标准参数渐开线齿形，与非渐开线齿形复合的锁闭齿轮插齿刀刀齿的排列、刀具齿数的选择以及刀具设计的基本方法，介绍用限制区域选择插齿刀变位系数的新方法，并给出刀具齿顶后角与侧螺旋角的关系曲线，为插齿刀参数的选择提供依据.结果表明，采用上述方法设计非标准复合齿轮插齿刀，可简化计算和提高设计效率
This paper develops a mathematical model for the solution to the longitudinal tooth curve of an internal gear shaver based on the simplified principle for space transmission of a helical gear pair without flank clearance , and proposes a calculating approach of the profile modification of the grinding wheel to be used for grinding the longitudinal tooth curve of the shaver 摘要用简化的空间螺旋齿轮作无侧隙啮合传动的原理，建立了求解内剃齿刀齿向曲线的数学模型，并给出了修磨这种齿向曲线的盘形砂轮的廓形计算方法。
