螺旋叶片成形胎具的一种设计方法

The Mold Design Method of Helical Vane

运用解析几何方法,从等螺距旋面和螺旋线的参数方程入手,采用坐标系旋转等方法得出螺旋面的有关特性,并根据这些特性提出一种螺旋叶片水平形成胎具的设计方法,使一胎具即可压制多种导程的螺旋叶片.

The paper put forward the mold design method of hilical vane being taken shape horizontally on space analytic geometry theory.proceeding from the parameter equation of equal pitch helical plane and helical line,and using coordinate transformation and coordinate rotation way.that making a mold pressing various helical pitch helical vane
