【正文】 摘要 I 畢業(yè)設(shè)計 立式?jīng)_擊粉碎機的結(jié)構(gòu)設(shè)計 摘 要 本課題是立式?jīng)_擊粉碎機的結(jié)構(gòu)設(shè)計。首先介紹了一下國內(nèi)外粉碎機生產(chǎn)技術(shù)的發(fā)展?fàn)顩r以及各種不同的粉碎機設(shè)備，然后在這些粉碎機的基礎(chǔ)上對本設(shè)計進行整體方案的確定。 本設(shè)計主要包括粉碎、分級和傳動部分。粉碎部分包括粉碎盤和齒形襯套。粉碎盤為銷棒式結(jié)構(gòu)，錘體圓周排列，出料粒徑小，適用于熱敏性與韌性材料的粉碎；齒形襯套為圓弧形，空氣極易形成局部高速渦漩流場，使物料產(chǎn)生高速震顫，加劇了物料間的碰撞；分級機構(gòu)可以使物料避免過度粉碎，達到所需粒徑時在氣流粘滯力的作用下及時排出；其傳 動系統(tǒng)采用帶傳動，可以緩沖吸振，傳動平穩(wěn)無噪聲，且適用于較大距離間兩軸的傳遞。設(shè)計過程中的很多數(shù)據(jù)都是采用以往的經(jīng)驗值，選材部分也是通過以往的經(jīng)驗來選擇。通過查閱相關(guān)的技術(shù)手冊來確定一些標(biāo)準(zhǔn)件。 設(shè)計的過程中首先分析立式粉碎機的結(jié)構(gòu)以及粉碎機的工作原理，粉碎的方法。知道各部分的功能及組成。其次查閱相關(guān)緊固件的尺寸，理論聯(lián)系實際確定各部件選用的制作材料。最后運用 CAD畫出總的裝配圖及主要部件的零件圖。 關(guān)鍵詞 ： 立式?jīng)_擊粉碎機；結(jié)構(gòu)設(shè)計；二維圖。 Abstract 錯誤 !未找到引用源。 ABSTRACT The issue is the structural design of vertical impact crusher. First introduced the look at home and abroad crusher manufacturing technology development and a variety of mill equipment, and then on the basis of these mill the determination of the overall program design. The design includes crushing, classification and transmission part. Some, including crushing and grinding plate gear bushing. Crush plate structure for the pin bar, hammer circle arrangement, the material particle size, suitable for grinding heat sensitive materials with toughness。 toothed, rounded bush, the air can easily form a local highspeed vortex flow field, so that materials produce highspeed tremor, increased collisions between the material。 rating agencies can make the material to avoid excessive grinding, to achieve the required particle size in the air when the effect of viscous forces to discharge the waste。 its transmission system with belt drive, you can buffer absorber, transmission stable noisefree and suitable for large distance between the two axes of the transfer. Many of the design process the data are based on past experience the value, selection in part by past experience to choose. Through access to relevant technical manuals to determine the number of standard parts. The process of analyzing the design of vertical mill of the structure and working principle grinder, grinding method. Know the functions and position of the various parts. Second, the size of accessrelated fasteners, theory with practice to determine the production of materials of all parts used. Finally, we use CAD to draw general assembly drawing and part drawings for the main ponents.
