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 研究加工不等齒厚的非標(biāo)準(zhǔn)參數(shù)漸開線齒形,與非漸開線齒形復(fù)合的鎖閉齒輪插齒刀刀齒的排列、刀具齒數(shù)的選擇以及刀具設(shè)計(jì)的基本方法,介紹用限制區(qū)域選擇插齒刀變位系數(shù)的新方法,并給出刀具齒頂后角與側(cè)螺旋角的關(guān)系曲線,為插齒刀參數(shù)的選擇提供依據(jù).結(jié)果表明,采用上述方法設(shè)計(jì)非標(biāo)準(zhǔn)復(fù)合齒輪插齒刀,可簡化計(jì)算和提高設(shè)計(jì)效率
