【摘要】 针对双折线卷筒的主要参数即绳槽节距系数K₁、卷筒与钢丝绳绳径比K₂、卷筒长度与直径比K₃、折线段对应圆心角θ、滑轮组倍率m、钢丝绳缠绕层数s、钢丝绳直径d,在比较历史数据的基础上,采用多因素多水平正交试验法,根据备参数的贡献率,确定其最佳组合。更多还原

【Abstract】 The advantage of traditional drum’s spiral rope groove winding method is the wire rope can wind along the spiral grooving smoothly when single layer winding, whose max. disadvantage is rope disorder, inner deflection becomes bigger, broken ropes happen when multi-layers winding. To change this phenomenon, aim to main technical data of double broken lines drum, that is rope groove pitch coefficient K1, drum and wire rope diameter ration K2, drum length and diameter ration K3.更多还原
