At first, it is introduction about the belt conveyor. Next, it is the principles about choose ponent parts of belt conveyor. After that the belt conveyor abase on the principle is designed. Then, it is checking putations about main ponent parts. The ordinary belt conveyor consists of six main parts: Drive Unit, Jib or Delivery End, Tail Ender Return End, Intermediate Structure, Loop TakeUp and Belt. At last, it is explanation about fix and safeguard of the belt conveyor. Today, long distance, high speed, low friction is the direction of belt conveyor’s development. Air cushion belt conveyor is one of them. At present, we still fall far short of abroad advanced technology in design, manufacture and using. There are a lot of wastes in the design of belt conveyor. Keyword: belt conveyor。 張緊裝置在使用中應滿足的要求 ....................... 錯誤 !未定義書簽。 拉緊裝置布置時應遵循的原則 .......................... 錯誤 !未定義書簽。main parts 河南理工大學畢業(yè)設計論文 Abstract 、 2 目錄 摘要 ..................................................................................................................... 1 Abstract ................................................................................................................ 2 1緒論 .................................................................................................................. 4 2帶式輸送機概述 ................................................................................................. 2 帶式輸送機的應用 .................................................................................. 2 帶式輸送機的分類 .................................................................................. 2 各種帶式輸送機的特點 ........................................................................... 3 帶式輸送機的發(fā)展狀況 ........................................................................... 4 帶式輸送機的工作原理 ........................................................................... 4 帶式輸送機的結構和布置形式 ................................................................. 5 帶式輸送機的結構 ........................................................................ 6 布置方式 ...................................................................................... 6 3 帶式輸送機的設計計算 ...................................................................................... 7 已知原始數據及工作條件 ...................................................................... 10 計算步驟 .............................................................................................. 10 帶寬的確定 : .............................................................................. 10 ...................................................................... 13 圓周驅動力 ........................................................................................... 13 計算公式 .................................................................................... 13 主要阻力計算 ............................................................................. 15 主要特種阻力計算 ...................................................................... 17 畢業(yè)設計論文 目錄 2 附加特種阻力計算 ...................................................................... 17 傾斜阻力計算 ............................................................................. 18 ........................................................................................ 19 傳動軸功率（ AP ）計算 ............................................................. 19 電動機功率計算 ......................................................................... 19 輸送帶張力計算 .................................................................................... 20 輸送帶不打滑條件校核 ............................................................... 20 輸送帶下垂度校核 ...................................................................... 21 各特性點張力計算 ...................................................................... 22 傳動滾筒、改向滾筒合張力計算 ........................................................... 25 改向滾 筒合張力計算 .................................................................. 25 傳動滾筒合張力計算 .................................................................. 25 傳動滾筒最大扭矩計算 ......................................................................... 25 拉緊力計算 ........................................................................................... 26 ...................................................................... 26 4 驅動裝置的選用與設計 .................................................................................... 27 電機的選用 ........................................................................................... 27 傳動裝置的總傳動比 ........................................ 錯誤 !未定義書簽。ksv*3t nGK8!z89AmYWpazadNuKNamp。ksv*3tnGK8! z89Am YWpazadNuKNamp。ksv*3tnGK8! z89Am YWpazadNuKNamp。ksv*3tnGK8! z89Am YWpazadNuGK8!z89AmYWpazadNuKNamp。 MuWFA5ux^Gj qv^$UE9wEwZQcUE% amp。 MuWFA5uxY7JnD6YWRr Wwc^vR9CpbK! zn%Mz849Gx^Gjqv^$UE9wEwZQcUE% amp。 MuWFA5uxY7JnD6YWRrWwc^vR9CpbK! zn%Mz849Gx^Gj qv^$UE9wEwZQcUE% amp。 gTXRm6X4NGpP$vSTTamp。gTXRm 6X4NGpP$vSTTamp。 gTXRm 6X4NGpP$vSTTamp。 ksv*3t nGK8! z89Am YWv*3t nGK8! z89Am YWpazadNuKNamp。 ksv*3t nGK8! z89Am YWv*3t nGK8! z89Am YWpazadNuKNamp。 ksv*3t nGK8!z89Am YWpazadNuKNamp。MuWFA5uxY7JnD6YWRr Wwc^vR9CpbK! zn%Mz849Gx^Gj qv^$UE9wEwZQcUE%amp。 ksv*3t nGK8! z89Am v^$UE9wEwZQcUE%amp。MuWFA5uxY7JnD6YWRr Wwc^vR9CpbK!zn%Mz849Gx^Gj qv^$UE9wEwZQcUE% amp。MuWFA5uxY7JnD6YWRr Wwc^vR
