摘要

许多制造业使用金属板材来优化产品的重量。在过去的几十年里，成形工艺不断发展。分度机构已用于制粉、织造、包装等连续生产。钣金剪切已被广泛用于优化零件和产品的重量。曲柄开槽机构是间歇式作业中应用最广泛的机构。该机制已被日内瓦机制所取代。本文旨在利用曲线理论推导开槽槽轮的数学关系。利用DH符号推导了其运动特性，并对所设计的带销日内瓦轮进行了有限元分析。分析了驱动曲柄销沿轮槽滑动操作机构时产生的接触应力。

Analysis on slot curvature and contact stresses on Geneva wheel

Many of the manufacturing industries use sheet metal for optimizing the weight of the products. Forming process has been successively increasing during the past few decades. Indexing mechanisms have been used in milling, weaving, packing, etc. for continuous production purpose. Shearing of sheet metals has been widely used for optimizing the weight of the components and products. Crank slotter mechanism was widely used in the mechanisms for intermittent operations. This has been replaced by Geneva mechanism. The paper aims at deriving the mathematical relations for slotted Geneva wheel using curve theory. The kinematic characteristics are derived using the DH notations Finite element analysis has been done on the designed Geneva wheel with pin. It is analysed for the contact stresses when the drive crank pin slides along the slots of the wheel to operate the mechanism.
