摘 要

刮板輸送機(jī)在煤礦生產(chǎn)企業(yè)的生產(chǎn)設(shè)備中是使用量較大、消耗較多的重要運(yùn)輸設(shè)備，其中機(jī)頭的機(jī)頭部是整臺刮板輸送機(jī)的最重要的部件，因?yàn)樗P(guān)系到刮板輸送機(jī)的牽引速度、牽引力等重要參數(shù)。此次對刮板輸送機(jī)機(jī)頭部設(shè)計(jì)的目標(biāo)是：使用90kW電動(dòng)機(jī)，經(jīng)過液力耦合器及三級圓錐圓柱減速器帶動(dòng)鏈輪，并保證牽引力適應(yīng)刮板輸送機(jī)整體要求。對刮板輸送機(jī)輸送能力、輸送機(jī)阻力、電機(jī)功率進(jìn)行了計(jì)算、并對鏈輪進(jìn)行了設(shè)計(jì)等。在結(jié)構(gòu)方面，通過在過渡槽表面堆焊“八”字型耐磨材料，達(dá)到減少磨損的目的。提高了刮板輸送機(jī)的使用壽命，降低了刮板輸送機(jī)的維護(hù)成本, 繪制了刮板輸送機(jī)的總體結(jié)構(gòu)圖、機(jī)頭傳動(dòng)裝置圖、機(jī)尾過渡溜槽、鏈輪等。

Abstract

The scraper conveyer is to use to measure the big important equipment of much consumption in coal mine , is overall key in which nose power department, because it concern scraper transport plane pull the important parameters such as speed and haulage. The goal that designed this time for the scraper nose department of transport plane is: Using the motor process of 90 kW 3 level cone cylinder gear reducers drive sprocket , and guarantee that nose size and haulage meet the scraper overall requirement of transport plane. Calculation includes scraper chain speed partially to determine that sprocket is designed , gear reducer designs. In which, include scraper and scraper chain, the groove of central section select , transmission score match , tooth frequently distribution calculation, gear geometry parameter calculation and the design of strength school nucleus and axle and school nucleus. Structural aspect, lead-over groove surface add to weld the word strip of shaped steel of " 8 ", replace surface with line friction friction, arrival reduces the purpose of friction. Have reduced the maintenance cost of scraper transport plane, make the design of the scraper nose department of transport plane last satisfy Zong the working condition of picking face.
