本文介绍了一种凸轮钢带传动机构,由头尾衔接的无端钢带形成又旋转、又轴向前进的运动表面为成形制品的成型面和连续输送制品的载体,能连续制造复合材料/玻璃钢管道。文中分析了凸轮钢带机构中的受力状况,指出只有采用合理的芯轴结构,才能使钢带轴向移动顺利、环向不出现滑移。文中还指出,在制造小口径复合材料/玻璃钢管时,钢带在芯轴上处于弹塑性状态,必须采用弹性好、延伸率高的不锈钢带才能满足使用要求。文中给出了一系列计算式,为机构设计提供了基础。 In this paper, a kind of cam steel belt transmission mechanism is introduced. The endless steel belt with head-to-tail articulation is formed and rotated. The axially moving surface is the carrier of the shaped surface and the continuous conveying product. The continuous manufacturing of the composite / fiberglass pipe . In this paper, the stress state of the cam steel belt mechanism is analyzed, and it is pointed out that only by adopting a reasonable mandrel structure, the steel strip can move smoothly in the axial direction without any slip in the ring direction. The article also pointed out that in the manufacture of small diameter composite / glass fiber reinforced plastic, the steel strip in the elastic state of the mandrel must be good elasticity, high elongation stainless steel to meet the requirements. The paper gives a series of formulas, which provide the foundation for the design of the mechanism.
