搅拌车圆柱罐体部分通常采用圆柱螺旋线方程,即等螺旋角等螺距设计;其前后锥叶片型线的大端螺旋角通常取相同的值,以便得到光顺的的叶片。文献[1]提出了采用均变圆柱螺旋线的方法,以达到在锥段叶片型线大端螺旋角不同时也能光顺对接的目的;文献[2]对其中的均变角圆柱螺旋线的方程进行了推导;笔者则推导出了搅拌车罐体非均变螺旋角圆柱螺旋线公式,并讨论其变化规律。
Cylindrical tank body part of the mixer usually cylindrical helix equation, the helix angle equal pitch design; its front and rear cone-shaped line of the large-end helix angle usually take the same value, in order to get a smooth blade. Literature [1] proposed the use of uniform cylindrical helix method in order to achieve the cone-shaped blade line at the same time the large helix angle but also smooth docking purposes; literature [2] of which the uniform angle of the cylindrical helix The equation was deduced. The author deduces the formula of cylindrical helix of non-uniform helix angle in tank of mixer, and discusses its changing rule.
