1、山東科技大學(xué)學(xué)士學(xué)位論文摘要本畢業(yè)設(shè)計(jì)的課題來源于“山東奧諾能源科技有限公司”的產(chǎn)品,是在其轉(zhuǎn)筒干燥機(jī)基礎(chǔ)上進(jìn)行的改進(jìn),主要設(shè)計(jì)任務(wù)是在轉(zhuǎn)筒內(nèi)部加入一根用來破碎大塊物料的破碎軸。本文在詳述國內(nèi)外轉(zhuǎn)筒干燥機(jī)研究現(xiàn)狀的基礎(chǔ)上,對(duì)轉(zhuǎn)筒干燥機(jī)內(nèi)部加入一根破碎軸的本體結(jié)構(gòu)進(jìn)行了設(shè)計(jì),對(duì)一些關(guān)鍵部分進(jìn)行了設(shè)計(jì)計(jì)算。重點(diǎn)是破碎式轉(zhuǎn)筒干燥機(jī)的破碎軸、破碎齒,破碎軸上的軸承選型,皮帶的選型,和帶輪的設(shè)計(jì)及校核。本文設(shè)計(jì)的破碎式轉(zhuǎn)筒干燥機(jī)采用的是直接加熱的干燥方式,同時(shí)在傳統(tǒng)轉(zhuǎn)筒干燥機(jī)的內(nèi)部加入一根破碎軸的基本框架;采用在破碎軸上固定多個(gè)破碎齒的方式,將破碎齒上
