畢 業(yè) 設(shè) 計(jì) 說 明 書（論文）中 文 摘 要 SGZ 刮板運(yùn)輸機(jī)頭部的設(shè)計(jì) 摘要 刮板輸送機(jī)是綜采工作面配套設(shè)備的重要組成部分,是煤炭裝運(yùn)的第一個(gè)環(huán) 節(jié)。因此，刮板輸送機(jī)的輸送能力在很大程度上決定了采煤工作面的生產(chǎn)能力和效 率。然而，我國生產(chǎn)技術(shù)落后，目前設(shè)計(jì)生產(chǎn)的刮板輸送機(jī)裝機(jī)功率小,輸送能力 低,運(yùn)輸距離短，耐久性差,可靠性低，壽命短。 本文基于機(jī)械設(shè)計(jì)，設(shè)計(jì)了中雙鏈型刮板運(yùn)輸機(jī)的機(jī)頭部。對其機(jī)頭傳動(dòng)裝 置，減速器，鏈輪組合等主要部件進(jìn)行了結(jié)構(gòu)設(shè)計(jì)。此次設(shè)計(jì)的中雙鏈型刮板輸送 機(jī)左右兩側(cè)對稱，可以在兩側(cè)壁上安裝減速器，以適應(yīng)左、右采煤工作面的需要。 另外，可以很容易將機(jī)尾改裝成機(jī)頭，而適應(yīng)各種特殊情況。此次設(shè)計(jì)的中雙鏈型 刮板輸送機(jī)的特點(diǎn)是結(jié)構(gòu)簡單,受力均勻,運(yùn)行平穩(wěn),摩擦阻力小,溜槽利用率高，彎 曲性能好,不易出現(xiàn)堵塞，具有很強(qiáng)的適應(yīng)性。 關(guān)鍵詞 刮板輸送機(jī) 減速器 鏈輪組件 畢 業(yè) 設(shè) 計(jì) 說 明 書（論文）外 文 摘 要 The design of SGZ scraper conveyer Abstract The scraper conveyer is the synthesis picking work surfaceimportant constituent of the supplementary equipment. It is thefirst link of the coal shipping. Therefore, the scraper conveyerdelivery capacity has decided the mining coal working surfaceproductivity and the efficiency in a great degree; however, ourcountry was lagged behind at present; the scraper conveyerinstalling equipment power is small. Based on the mechanical design,the design of double-chain scraper transports the helicopter.On the top machines drive device，reducer,sprocket combinations.This design center simple chain about the scraper conveyer twosides are symmetrical, may install the reduction gear on twosidewalls, by left meets, the right mining coal working surfaceneed. Moreover, it may very easily reequip the airplane tail thenose, but adapts each kind of peculiar circumstance. This design ofcenter simple chain of the scraper conveyer characteristicincludes: the structure is simple, the stress is even, movessteadily, the friction drag is small, the chute use factor high,the curving performance is good, It is not easy to appear stops up,has the very strong compatibility.
