電動(dòng)機(jī)的選型設(shè)計(jì) 鋼絲繩設(shè)計(jì)計(jì)算 滾筒部件的設(shè)計(jì)計(jì)算 主軸的設(shè)計(jì)計(jì)算及校荷 其他零部件的選用與設(shè)計(jì)。為此本人利用本科四年來(lái)所學(xué)習(xí)的書本知識(shí)以及現(xiàn)場(chǎng)學(xué)習(xí)經(jīng)驗(yàn)，并結(jié)合有關(guān)資料進(jìn)行設(shè)計(jì)。而礦山工業(yè)的提升機(jī)是關(guān)鍵設(shè)備，產(chǎn)品不斷更新?lián)Q代，老產(chǎn)品運(yùn)行年深日久，原本落后的結(jié)構(gòu)問題暴露突出，故障增多，嚴(yán)重影響礦山的安全運(yùn)轉(zhuǎn)，抑制了礦山工業(yè)的高速發(fā)展，給國(guó)民經(jīng)濟(jì)帶來(lái)了不良的影響。從 20世紀(jì) 50年代造第一臺(tái)礦井提升機(jī)以來(lái)，至今已設(shè)計(jì)制造、使用了近 10000 多臺(tái) (含從前蘇聯(lián)購(gòu)置的 200 余臺(tái) )。 關(guān)鍵詞 ：提升 絞車 減速器 聯(lián)軸器 主軸 全套圖紙，加 Q174320523 各專業(yè)都有 2 Abstract JT Series hoist for coal, metal mining, nonmetallic mineral movements in the tilt of roadway materials and personnel for use in small shaft can also be used as the upgrading of equipment. According to the different manufacturing process which could take the drum hoist structure casting a hybrid welding (support wheel for the casting, roller for welding) and the weldingtype. Reducer and the mechanical transmission system including the coupling, the main axis of mine hoist to raise the speed of a few because of the restrictions, generally 60 to 1 l0 / | between points, and the motor used to
