The stress and radial displacement will increase with the increment of half cone angle and lead.

螺旋输送器的最大应力强度和最大径向位移均与转速近似地成二次方关系；减小叶片壁厚，沉渣对螺旋叶片作用的正压力所引起的叶片的最大轴向位移增长较快；正常工况下，螺旋输送器的最大应力强度和最大径向位移都随着半锥角和导程的增加而增大。

By changing the value of the blade thickness, cone angle, lead and height of fillet weld, influences of these parameters on the strength and displacement of the screw conveyor are investigated which form the base for optimization of the conveyor structure.

论文还通过调整螺旋输送器的叶片壁厚、半锥角、导程和焊角高等几何结构参数，研究了各参数的变化对螺旋输送器强度和变形的影响，为结构优化设计奠定了基础。

The max stress and the max radial displacement of conveyor is also proportional to the square of rotational speed. With the decrease of the blade thickness, both the stress and axial displacement of conveyor increase rapidly. The stress and radial displacement will increase with the increment of half cone angle and lead.
