With its superior performance, it has been widely used in various sectors of national economy. Especially for the mine of high yield and high efficiency, belt conveyor has bee the key equipment of mechatronics technology in highefficient coal exploitation. At present, long distance, high power, large capacity, large obliquity are the direction of belt conveyor’s development. These developments will make it more widely used in the coal industry.The key technology of large slope angle and downward belt conveyor design is to maintain the stability of the material during operation and the rational design of brake system. In order to maintain the stability of the material , this design uses the herringbone shallow patterned belt and double row Vshaped roller group. To prevent the occurrence of runaway，a new kind of braking method is adopted in the design, according to the principle of various existing braking methods. This is a method that a generator is used in bination with a brake. And while braking, mechanical energy can be converted to electrical energy. The design focuses on the design of transmission system. It is posed of six parts: motor, generator, clutch, brake, coupling and drive roller. Taking into account the limited underground space, the brake system and drive system is designed into a whole, shareing a speed change mechanism. And according to the related parameters, some selection of the other ponents are maked in the design. The design of belt conveyor is pleted finally.In this design a new idea is proposed to the brake of the belt conveyor. And it has the value of further research.Keywords：belt conveyor；large obliquity；downwards transportatio；power braking目 錄1 概述 ......................................................................1 帶式輸送機(jī) .............................................................1 帶式輸送機(jī)的分類 ...................................................1 帶式輸送機(jī)的結(jié)構(gòu)原理 ...............................................1 國(guó)內(nèi)外帶式輸送機(jī)的發(fā)展現(xiàn)狀 .............................................1 大傾角帶式輸送機(jī) .......................................................2 深槽形帶式輸送機(jī) ...................................................2 壓帶式輸送機(jī) .......................................................3 裙邊帶式輸送機(jī) .....................................................3 大傾角下運(yùn)帶式輸送機(jī)設(shè)計(jì) ...............................................3 大傾角下運(yùn)帶式輸送機(jī)技術(shù)關(guān)鍵 .......................................3 增加傾角的主要方法 .................................................4 下運(yùn)制動(dòng)技術(shù) .......................................................52 帶式輸送機(jī)設(shè)計(jì) ............................................................7 工作條件與原始參數(shù) .....................................................7 輸送帶速度與寬度的確定 .................................................7 輸送帶速度的選擇 ...................................................7 輸送帶寬度的確定 ...................................................7 輸送帶寬度的核算 ...................................................8 輸送帶型號(hào)初選 .....................................................9 圓周驅(qū)動(dòng)力計(jì)算 ........................................................10 主要阻力 ..........................................................10 附加阻力 ..........................................................12 特種主要阻力 ......................................................12 附加特種阻力 ......................................................13 傾斜阻力 ..........................................................13 圓周驅(qū)動(dòng)力 ........................................................14 輸送帶張力計(jì)算 ........................................................14 輸送帶不打滑條件限制 ..............................................14 輸送帶下垂度的限制 ................................................15 運(yùn)行阻力計(jì)算 ......................................................15 各特性點(diǎn)張力計(jì)算 ..................................................16 輸送帶驗(yàn)算 ........................................................17 傳動(dòng)功率計(jì)算 ..........................................................18 滾筒傳動(dòng)軸功率 ....................................................18 電機(jī)功率計(jì)算 ......................................................19 傳動(dòng)滾筒相關(guān)參數(shù)計(jì)算 ..................................................19 傳動(dòng)滾筒合張力計(jì)算 ................................................19 傳動(dòng)滾筒直徑初選 ..................................................19 傳動(dòng)滾筒最大扭矩計(jì)算 ..............................................19 拉緊行程與拉緊力計(jì)算 ..................................................20 拉緊行程計(jì)算 ......................................................20 拉緊力計(jì)算 ........................................................203 傳動(dòng)裝置的設(shè)計(jì)與計(jì)算 .....................................................22 傳動(dòng)方案的確定 ........................................................22 電機(jī)選型 ..............................................................22 電動(dòng)機(jī)選型 ........................................................22 發(fā)電機(jī)選型 ........................................................23 減速器的設(shè)計(jì)與計(jì)算 ....................................................23 總傳動(dòng)比的計(jì)算 ....................................................23 傳動(dòng)比分配 ........................................................23 運(yùn)動(dòng)和動(dòng)力參數(shù)計(jì)算 ................................................24 直齒圓錐齒輪傳動(dòng)的設(shè)計(jì)與計(jì)算 ......................................26 直齒圓柱齒輪傳動(dòng)的設(shè)計(jì)與計(jì)算（軸Ⅱ與軸Ⅲ間） ......................29 其它齒輪設(shè)計(jì)與計(jì)算 ..................
