It has product quality and production efficiency, which direct impacts on the construction quality and progress of construction. Compulsory mixer is the most common and the highest utilization rate of concrete mixers。Double horizontal shaft mixer is a new-style mixer, which is widely used in many conditions because of the high mixing quality and productivity This paper begins with the mechanism and purpose of mixing. The materials leaves along the spiral of mobile on the work. Because of the two axis of rotation opposite direction, the materials between the two axis produces extrusion rolling and scrubbing, in order to meet the stirring mixed effect. It has been proved in the long-term production, through the horizontal Coaxial mixer surface of the leaf structure and shape of a reasonable layout and design, concrete’s quality and production efficiency will be greatly improved Combining with the advantages of three leafs, Concrete is going to mix as much as possible in the limited time through their orderly, rational layout. I do some theoretical analysis and a number of tests for the leaf-surface’s shape. Though the new design test, it overcomes shortcomings of traditional mixer, and notes that the new design may cause new problems. Though the theoretical analysis of the mixing process and concretely explicating the parametric design .Finally, it gives conclusions and suggestions Key words: concrete mixer; double horizontal shaft; improved blade 目 錄 前言………………………………………………………………………………1 1 總述……………………………………………………………………………3 1.1 攪拌的作用 ……………………………………………………………3 1.1.1 混凝土的組成 ……………………………………………………3 1.1.2 攪拌的任務 ………………………………………………………3 1.1.3合理的攪拌機理 …………………………………………………3 1.2 混凝土攪拌機的類型 …………………………………………………4 1.3 國內(nèi)外混凝土攪拌機的發(fā)展狀況 ……………………………………6 1.4 本文的內(nèi)容和方法 ……………………………………………………7 2 總體設計方案確定及動力元件選擇…………………………………………8 2.1 總體設計方案 …………………………………………………………8 2.2 電動機的選型 …………………………………………………………8 2.3 減速器的選型 …………………………………………………………9 2.4 聯(lián)軸器的選擇與計算…………………………………………………10 3 葉片的設計與計算 …………………………………………………………11 3.1 原有葉片的布置………………………………………………………11 3.2 設計葉片的布置………………………………………………………13 3.2.1葉片的布置………………………………………………………14 3.2.2 裹軸現(xiàn)象…………………………………………………………16 3.3 葉片的主要參數(shù)………………………………………………………17 3.3.1輸送葉片主要參數(shù)的設計………………………………………17 3.3.2 主軸轉(zhuǎn)速的確定…………………………………………………18 3.4 螺旋葉片的加工………………………………………………………24 3.4.1 葉片螺旋面的成形………………………………………………24 3.4.2坯料形狀的選擇…………………………………………………24 3.4.3 整圓坯料尺寸的確定……………………………………………24 3.4.4 壓模主要尺寸的確定……………………………………………26 3.5 螺旋葉片的制造工藝…………………………………………………27 3.5 螺旋葉片的校核………………………………………………………27 4 軸的設計與計算 ……………………………………………………………35 4.1 左軸的校核……………………………………………………………35 4.1.1 初步估算軸的直徑………………………………………………35 4.1.2 軸的結構設計……………………………………………………36 4.1.3 左軸加工工藝過程卡……………………………………………36 4.1.4 軸承的校核………………………………………………………37 4.1.5軸的校核…………………………………………………………39 4.2 鍵的校核………………………………………………………………40 4.3 銷軸的校核……………………………………………………………41 4.4 右軸的校核……………………………………………………………42 4.4.1初步估算軸的直徑………………………………………………42 4.4.2 軸的結構設計……………………………………………………43 4.4.3 軸的強度校核……………………………………………………44 4.4.4 軸承的校核………………………………………………………45 4.5 攪拌軸筒的校核………………………………………………………46 結論 ……………………………………………………………………………48 致謝 ……………………………………………………………………………49 參考文獻 ………………………………………………………………………50 附錄：……………………………………………………………………………52 外文資料與中文翻譯 ……………………………………………………52
