Study on the Meshing Characteristic of Quadruple-arc Spiral Bevel Gear

四圆弧弧齿锥齿轮是将四圆弧齿廓应用在锥齿轮上而得到的一种新的锥齿轮。与圆柱齿轮类似,四圆弧齿廓弧齿锥齿轮同时啮合点数较双圆弧弧齿锥齿轮获得增加,能极大地提高齿轮的承载能力。通过对加工四圆弧弧齿锥齿轮的盘状铣刀与齿轮毛坯的切削过程的分析,绘制出了四圆弧弧齿锥齿轮的啮合线图,计算了多点啮合系数以及多对齿啮合系数,为四圆弧弧齿锥齿轮的强度计算以及尺寸设计提供了计算依据。

The quadruple-arc spiral bevel gear is a new type of spiral bevel gear which is obtained by apply the quadruple-arc tooth on the bevel gear. The meshing points of quadruple-arc spiral bevel gear are increased compare with double-arc spiral bevel gear,and the carry capacity is also increased. The mesh line figure is obtained by analyzing the cutting process of quadruple-arc spiral bevel gear,the multi-meshing points coefficient and multi-meshing teeth coefficient are calculated. The basis of calculation for the strength calculation and dimensions design of quadruple-arc spiral bevel gear is provided.
