电动石磨仿真设计毕业论文.doc

摘 要 二十世纪七十年代以前，传统石磨为人们做出了巨大的贡献。随着科技的发展，电动石磨开始出现，提高了生产率。与此同时，更多的自动化设备也相继出现，例如豆浆机，在生产生活中给人们带来了方便。但是，从实验对比发现各种高速加工出来的农产品的营养成分远低于石磨低速研磨的营养成分，且石磨加工出来的产品口感更好。因此，随着人们生活水平的提高，石磨加工的产品将会日益受到消费者青睐。 传统石磨外形和原理都很简单，两块相对的圆形石磨在人力或畜力的驱动下作定向转动，将夹在其中的豆类等物碾碎得到需要的产品。此加工方法的优点是，石磨转速很低，能使豆类中蛋白质免受破坏；缺点是劳动强度大，不便于长时间加工。本文将参照传统石磨的原理作出设计，设计一款不同于市场上现有的半自动电动石磨。石磨主体可分为传动部分和工作部分，上半部分为工作部分，工作部分颠覆传统的单面接触加工，设计为两面接触加工，一个磨齿面粗加工，另一个磨齿面精加工，这样能实现石磨重量轻量化，加工效率提高和加工效果改善等效果；下半部分为传动部分，主要由电机和减速器实现减速并提供高扭矩。 应用solidworks对模型建模，分析、优化并仿真。对关键部分的零件进行有限元分析，验证设计的合理性，在最大程度上保证设计的可行性和合理性。 关键词：石磨 营养 半自动 仿真 有限元分析 Abstract Before the twentieth Century seventys, the traditional stone made enormous contributions to the people.With the development of science and technology,Power stone began to appear,Improved productivity At the same time, More automation equipment appeared,For example Soybean Milk machine, in the production of life brings people a convenient. However, from the comparison nutrition high processed agricultural products is far lower than the nutritional components of low-speed grinding stone, and stone processing out products taste better. Therefore, with the improvement of peoples living standard, stone processing products will be increasingly favored by consumers. The traditional stone appearance and the principle is very simple, two oppositely circular stone in the human or animal driven directional rotation, will be caught in the crush the beans, get the product. Advantages of this processing method is, stone speed is very low, can make soy protein from damage; disadvantage is the high labor intensity, not easy to long time processing. This paper will be according to the principle of traditional stone make a design, design a different from the existing market semi automatic electric stone. Stone body can be divided into the transmission part and the part work, part work, part, part to subvert the traditional processing of the single contact, design for the two contact machining, a grinding surface rough
