This paper proposes the concrete design, in view of the cooling system of Mandrill. According to the requirements and the fundamental principle of cooling system, the paper chose the first as a selection of the design, by a detailed analysis and parison of working principle ,as well as advantages and disadvantages of the three proposals. Through consultancy to relevant materials, analysis and calculation the paper de termines the model of motors, reducers, shaft, coupling, keys, and other important parts,and checks up the important parts. On this basis, then design the structure of other nonstandard ponents, such as, rotating on the feeder, move steel and other imp ortant ponents etc. According to the above method, the task of cooling mandrel rotation can be plete well【 17】 . Key words: mandrill 。由此，本文針對(duì)芯棒的冷卻系統(tǒng)提出了具體的設(shè)計(jì)方案，結(jié)合任務(wù)要求和冷卻的基本理論，對(duì)三個(gè)方案的工作原理和優(yōu)缺點(diǎn)進(jìn)行了細(xì)致的分析 和比較，選擇了第一種作為設(shè)計(jì)的選定案。芯棒工作后的溫度升高，損耗不斷的擴(kuò)大，增加了生產(chǎn)的成本，因此芯棒的維護(hù)也得到了很大的重視。按上述方法完成的設(shè)計(jì)能很好的完成芯棒旋轉(zhuǎn)冷卻的任務(wù)。 proposal. 內(nèi)蒙古科技大學(xué)畢業(yè)設(shè)計(jì)說(shuō)明書(shū) IV 目 錄 摘 要 ........................................................................................................................................II Abstract ....................................................................................................................................
