【正文】 帶、繩芯平帶和片基平帶等；另一方 面其性能也越來越高， 在許多場合帶傳動已代替鏈傳動和齒輪傳動。 傳動帶是機械傳動的重要傳動方式，帶傳動的主要部件，其性能將直接影響機械設備的質量。 Mechanical design。 此外， vb 上手比較容易，且能建立友好的界面，其功能比較實用，便于理解面向對象編程，這也是此次設計選取 vb 的原因?？偟膩砜矗敬卧O計包含了數(shù)學模型的建立和程序的編制。因此，掌握 V 帶傳動的設計是十分重要和必要的。 在進入工業(yè)時代以來，機械制造 始終是創(chuàng)造社會財富的主要來源 ， 是衡量國家綜合國力的重要指標 。 I 普通 v 帶參數(shù)化設計系統(tǒng) 摘 要 在 隨著科學技術的發(fā)展，機械制造業(yè)的應用十分廣泛。特別是在農(nóng)業(yè)機械、工程機械、 軍事應用當中占據(jù)著重要位置。而對于制造業(yè)，例如一些大型的機械設備，一般都是要依靠機械傳動提供所需要的動力，而在機械傳動中 V 帶傳動式最傳統(tǒng)也是現(xiàn)在最為廣泛的機械傳動 。本篇文章應用機械設計方法，通過 vb 軟件強大的功能，使得普通 v帶的參數(shù)化系統(tǒng)得到實現(xiàn)，與傳統(tǒng)的設計方法相比 ，極大地提高工作效率，減少了大量的工作時間。當設計的系統(tǒng)完成時，我們可以得到一個可視化的操作界面，此界面可以輸入一些 用戶給定的原始條件 ，然后程序自動進行 設計校核 計算，并得到相應的結果。 關鍵詞： V帶傳動； 機械設計； 數(shù)學模型 II Abstract In with the development of science and technology, mechanical manufacturing used widely. Especially in agricultural machinery, construction machinery, application of military occupy an important position. In the industrial age since, machinery manufacturing is always create the main source of social wealth, it is to measure countries an important index of the prehensive national strength. And for manufacturing, such as some largescale mechanical equipment, are generally will depend on the mechanical transmission provide needed power, and in the mechanical transmission in the V belt type the most traditional and it is also the most widely the mechanical transmission. Therefore, master V belt transmission design is very important and necessary. This article used the mechanical design method, through the vb software powerful functions, making mon v belt parameterization system implemented, and the traditional design method than, greatly improve work efficiency, reduce a lot of time. In general, the design includes establishing mathematics model and programming. When the design of the system is pleted, we can get a visual interface, the interface can input some known conditions and the program automatically calculation, and obtained the corresponding results. In addition, vb to more easily, and can establish friendly interface, its function is more practical, easy to understand objectoriented programming, this also is the design of the reason for selecting vb. Keywords: v belt transmission。 Mathematical model 目錄 III 第 1 章 緒 論 ...................................................................................................................................................... 1 生產(chǎn)需求狀況 ............................................................................................................................................. 1 選題意義和背景技術 ................................................................................................................................ 1 本論文的主要內(nèi)容 .................................................................................................................................... 3 帶傳動簡介 ................................................................................................................................................. 3 第 2 章 V帶傳動設計計算方法 ....................................................................................................................... 5 建立設計模型 ............................................................................................................................................. 5 設計思路 ..................................................................................................................................................... 5 設計流程及流程圖 ..................................................................................................................................... 5 設計流程 .............................................................................................................................................. 5 設計的框圖 ......................................................................................................................................... 6 具體的設計及計算過程 ............................................................................................................................ 8 確定計算功率 ..................................................................................................................................... 8 帶型號的選取 ..................................................................................................................................... 8 帶速的計算 ......................................................................................................................................... 9 初定中心距的范圍 ...........................................................................................................................10 帶長的計算及基準長度的選取 ......................................................................................................10 中心距和包角的計算 ........................................................................................................................10 包角的驗算 ....................................................................................................................................... 11 帶根數(shù)的確定 .................................................................................................................................... 11 軸上載荷的確定 ...............................................................................................................................12 確定帶輪的結構 ......................
