齿轮参数对滚齿齿根沉切量的影响

Effect of Gear Parameter on Amount of Root Undercut after Hobbing

采用多因素试验法,选取齿轮参数中的模数、压力角、螺旋角、齿顶高系数、齿根高系数、变位系数和配对齿轮齿顶高系数来设计正交试验,研究齿轮参数对渐开线起始圆沉切量的影响。结果表明,对滚齿齿根沉切量影响较为明显的齿轮参数是齿根系数、配对齿轮齿顶高系数、模数和压力角。通过优化后的齿轮参数实际验证了该结论,产品设计初期为提高齿轮可制造性提供理论依据。

The effect of different gear parameters on the amount of root undercut is investigated by means of orthogonal experiment.The module,pressure angle,helix angle,addendum coefficient,dedendum coefficient,modification coefficient,and the addendum coefficient of the mating gears are selected to design the orthogonal experiment.Experimental results show that the parameters obviously affecting the amount of root undercut are dedendum coefficient,addendum coefficient of mating gears,module and pressure angle.The validity of the result is verified by experiments.
