摘要
针对外径渐变而内径不变的螺杆建立了力学方程,并同外径不变而内径渐变的螺杆进行了对比,为挤压螺杆的合理设计提供了一种分析方法和设计依据.
A mechanic equation of screw extruder whose major diameter decreases gradually while its minor diameter keeps unchanged was set up.This equationwas compared with that for screw extruder whose minor diameter increases gradually while its major diameter keeps unchanged.From that, we got a new analytical method and design information for proper design of screw extruder.
