cone back face rib

Takes the tooth profile of straight bevel gear according to unfold surface of the back of bevel gear on equivalent cylindrical gears tooth profile processing as the basis,first infers the spatial equation of unfold surface of the back of bevel gear after mapping,after but infers the conical surface equation of the back of bevel gear,and further infers the mathematics equation of mating surf.

以直齿圆锥齿轮的齿形按背锥展开面上的当量圆柱齿轮的齿形加工为依据,首先推导出背锥展开面映射后的空间方程,而后推导出背锥锥面方程,并根据空间方程和锥面方程进一步推导出啮合面的数学方程。
