JN-A型米粉擠絲機零部件的設(shè)計

包括論文，整套cad圖紙和答辯ppt

摘要
米粉生產(chǎn)都是沿用傳統(tǒng)工藝和手工操作，產(chǎn)量低,勞動強度大，衛(wèi)生條件差，成品包裝簡陋甚至無包裝。為了適應(yīng)現(xiàn)代社會對食品的需要，傳統(tǒng)的米粉條正逐步走向生產(chǎn)工業(yè)化，食用方便化，品種多樣化，從小作坊進入工廠。研究米粉條加工的發(fā)展進程，工藝技術(shù)的關(guān)鍵，存在的問題，發(fā)展方向，對推進這一傳統(tǒng)食品的發(fā)展，有著深遠的意義。減速器是許多機械設(shè)備傳動機構(gòu)的重要部件之一，其性能的好壞與用戶的經(jīng)濟效益及社會效益有著密切的關(guān)系，此文的減速器的設(shè)計包括，V型皮帶輪的設(shè)計，斜齒圓柱齒輪的設(shè)計，主軸的設(shè)計，減速器箱體的設(shè)計，箱體的密封與潤滑，以及減速器內(nèi)各種標準零件的選擇，其中包括軸承的選擇,由于減速器的穩(wěn)定性對安全生產(chǎn)的影響，所以應(yīng)提高減速器的穩(wěn)定性。
關(guān)鍵字：減速器，皮帶輪，斜齒圓柱齒輪，主軸，密封，潤滑，穩(wěn)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.
Key words :Reduction gear , pulley ,helical gear ,shaft ,sealing ,slip ,stability .
