皮带助卷机构的三维设计及仿真 摘要 皮带助卷器是精整线、冷轧上必不可缺的设备之一，通常用于冶金行业，如铝材、钢铁、铜材等。在对薄带钢进行精整、冷轧的生产过程中，需要通过皮带助卷器，将最初的2~3圈带钢缠绕到卷取机的卷筒上，产生初始的张力，然后才能进行张力轧制和卷取，由此可见皮带助卷器在冷轧带钢中有极其重要的作用。直型冷轧带钢，在助卷皮带的张力作用下会产生弹塑性弯曲变形，同时在皮带施加的径向压力下，带钢会受到卷筒与皮带之间的摩擦力作用。卷筒转动时，助卷皮带在摩擦力的作用下随之一起转动，带钢头部经导板进入卷筒与皮带之间，贴合卷筒表面卷龋 本文主要是针对厚为0.3~2.3mm，宽为700~1630mm的热镀锌软钢和高强钢钢板进行的皮带助卷器设计，首先，计算带钢的弯曲力矩和皮带张力；其次，对张紧油缸和摆动油缸进行型号选取和推力校核；然后，运用Solid Works软件对助卷器进行三维建模，模拟其工作过程；最后，为了使其满足所需强度和刚度要求，采用Solid Works Simulatio
n工具对悬臂支撑轴进行有限元分析。 关键词：皮带助卷机；皮带；有限元分析；油缸 ABSTRACT Belt rewi
