中文摘要:
      目的 研究纸张在重叠分离送纸机构中所受变形力的特点,为纸张运动摩擦分析提供依据。方法 首先推导公式得出纸张正常分离条件,把纸张作为弹性梁模型,利用Clapeyron三弯矩定理分析纸张表面的变形力。结果 纸张在重叠区域变形力正比于交叠量;剥离轮的宽度越大,变形力越大;变形力随着剥离轮与送钞轮的左边距的增加先减小后增大;送钞轮宽度对变形力的影响不大。结论 通过对弹性梁模型的分析,获得了纸张在重叠区域变形力随结构参数变化的影响规律,并得到了能使纸张受力均衡的剥离轮和送钞轮的左边距值,为重叠机构的设计提供参考。
英文摘要:
      The work aims to study the deformation force features of the paper sheet which is passing through the overlap separation mechanism to provide basis for its kinetic friction analysis. Firstly, the formula was derived to obtain the normal separation condition of paper sheet. Then, with the paper sheet as the elastic beam model, the deformation force acting on the paper sheet surfaces was analyzed with the Clapeyron’s theorem of three moments. The results showed that the deformation force of paper sheet in the overlap area was proportional to the overlap. The wider the gate-roller was, the greater the deformation force was. The deformation force decreased and then increased with the increase of the edge distance of the gate-roller and feed-roller at the left side. The width of the feed-roller had hardly any effect on the deformation force. Based on the analysis of elastic beam model, the law of influence of paper sheet's deformation force in the overlap area changing with the structural parameters is obtained and the values of the edge distance of the gate-roller and feed-roller at the left side are acquired to provide reference for the design of overlap mechanism.
