JN-A型米粉挤丝机零部件的设计(任务书,论文说明书7000字,答辩幻灯片ppt,cad图纸)
摘要
米粉生产都是沿用传统工艺和手工操作，产量低,劳动强度大，卫生条件差，成品包装简陋甚至无包装。为了适应现代社会对食品的需要，传统的米粉条正逐步走向生产工业化，食用方便化，品种多样化，从小作坊进入工厂。研究米粉条加工的发展进程，工艺技术的关键，存在的问题，发展方向，对推进这一传统食品的发展，有着深远的意义。减速器是许多机械设备传动机构的重要部件之一，其性能的好坏与用户的经济效益及社会效益有着密切的关系，此文的减速器的设计包括，V型皮带轮的设计，斜齿圆柱齿轮的设计，主轴的设计，减速器箱体的设计，箱体的密封与润滑，以及减速器内各种标准零件的选择，其中包括轴承的选择,由于减速器的稳定性对安全生产的影响，所以应提高减速器的稳定性。
关键字：减速器，皮带轮，斜齿圆柱齿轮，主轴，密封，润滑，稳定性。

The JN-A rice noodle pushes the silk machine spare part design
Abstract:The rice noodle production all is continues to use the traditional process and the manual operation, the output is low, the labor intensity is big, the hygienic condition is bad, the end product packing crude does not even have the packing.In order to adapt the modern society to food need, the traditional rice starch noodles are moving to wards the production industrialization gradually, the edible convenience, the variety diversification, the workshop enters the factory since childhood.The research rice starch noodles processing development advancement, the processing technology key, the existence question, the development direction, to advances this traditional food the development, has the profound significance.Reduction gear is one of important machine equipment in transmission organ. Whose function goodness and badness have close relation to consumer`s economic effect and social benefits.The design of reduction gear in article include those,Those are design of v-pulley,design of helical gear, design of shaft,design of reduction case,sealing and slip of case,and chooseing kinds of criteria sections in reduction gear,therein include shaft bearing,because the stability of reduction gear must enhance as much as influence stability of reduction gear on security of work.
