【正文】 ich is put forwar by diploma project ,so as to find a appropriate design plan and to have a preliminary test. 畢業(yè)設(shè)計(jì)論文 III Using it ,we can improve technique level ,quality of production and manufacture efficiency, in this way labor will bigly be lightened. Machine tool which have been rebuilt will be more fit to produce accessory in large quantities .Regard to development of corporation , key of success is to meet movement demand of market with best quality,cheapest price and in a shortest time. Seeing from macroangle, using mechanical transmission to run mass production ,expect realizing producing automation, dropping labour intensity, it will reduce faults of manmade, improve processing accuracy and efficiency with mechanical transmission and even more with precision transmission we should use mechanical transmission to run mass production that our product will be intensed petition in international . Seeing from microangle, transmission line has strong points as bellows: high processing accuracy,good product quality, high producing efficiency, good flexible, low labour intensity and so on. Cost to buy a transmission line is smaller than expenses of human sources which have been saved, so in this way it will reduce cost of production The diploma project mainly put up technology design on norelation car of transmission line ,tensioning structure of smooth chain wheel , tight structure of aerodynamic bit and mark and outside framework of transmission line .in addition, it takes PLC puter programming control on electric control part. The carmode transmission which is put forward by the project takes updown track ,we set a curved track on transmission chain wheel.,so car will smoothly reverse on the curved track. Key words: nonsynchronization hit and mark and transmit line 畢業(yè)設(shè)計(jì)論文 IV tensioning structure tight structure of aerodynamic bit and mark. 中文摘要 ....................................................................................................................
