徐 州 工 程 學 院 畢 業(yè) 設(shè) 計 (論 文 ) I 摘要 皮帶機是一種運送物料的運輸機械，它廣泛地被用于礦山，碼頭，工廠等各種場合， 但是不同的場合對皮帶機的結(jié)構(gòu)的要求是不同的，本設(shè)計是以礦山運輸為背景，對皮帶 機的結(jié)構(gòu)進行了設(shè)計和計算，本設(shè)計先對皮帶機傳動系統(tǒng)的運動進行了力學分析。對皮 帶機的保養(yǎng)與維護進行了詳細的說明，在拉緊裝置的設(shè)計中，為了對設(shè)備進行優(yōu)化，彌 補其他拉緊裝置帶來的不足，本設(shè)計采用液壓拉緊裝置對系統(tǒng)進行了拉緊，同時對其他 輔助原件也做了必要的計算和選擇。 關(guān)鍵詞 皮帶機；輸送帶；液壓拉緊 徐 州 工 程 學 院 畢 業(yè) 設(shè) 計 (論 文 ) II Abstract Belt- machine is a kind of machine which is used to transport the goods ,it is widely used in the place of mine,dock,factory and so on ,but they request different structures in different places. This article is on the ground of mine .and it briefly devises and computes the structure of Belt- machine .first，this article analyses the driving system of Belt- machine .and then gives the brief maintenance and maintain of how to employ the belt-machine .in the design of tense equipment , in order to better the equipment and make up the deficiency of other equipments .here we chose the hydraulic system , and the same time ,this article also gives the compute and chose of others assistant elements.
