【正文】 I 普通 v 帶參數(shù)化設(shè)計(jì)系統(tǒng) 摘 要 在 隨著科學(xué)技術(shù)的發(fā)展，機(jī)械制造業(yè)的應(yīng)用十分廣泛。特別是在農(nóng)業(yè)機(jī)械、工程機(jī)械、 軍事應(yīng)用當(dāng)中占據(jù)著重要位置。 在進(jìn)入工業(yè)時(shí)代以來，機(jī)械制造 始終是創(chuàng)造社會財(cái)富的主要來源 ， 是衡量國家綜合國力的重要指標(biāo) 。而對于制造業(yè)，例如一些大型的機(jī)械設(shè)備，一般都是要依靠機(jī)械傳動提供所需要的動力，而在機(jī)械傳動中 V 帶傳動式最傳統(tǒng)也是現(xiàn)在最為廣泛的機(jī)械傳動 。因此，掌握 V 帶傳動的設(shè)計(jì)是十分重要和必要的。本篇文章應(yīng)用機(jī)械設(shè)計(jì)方法，通過 vb 軟件強(qiáng)大的功能，使得普通 v帶的參數(shù)化系統(tǒng)得到實(shí)現(xiàn)，與傳統(tǒng)的設(shè)計(jì)方法相比 ，極大地提高工作效率，減少了大量的工作時(shí)間。總的來看，本次設(shè)計(jì)包含了數(shù)學(xué)模型的建立和程序的編制。當(dāng)設(shè)計(jì)的系統(tǒng)完成時(shí)，我們可以得到一個(gè)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(jìn)行 設(shè)計(jì)校核 計(jì)算，并得到相應(yīng)的結(jié)果。 此外， vb 上手比較容易，且能建立友好的界面，其功能比較實(shí)用，便于理解面向?qū)ο缶幊?，這也是此次設(shè)計(jì)選取 vb 的原因。 關(guān)鍵詞： V帶傳動； 機(jī)械設(shè)計(jì)； 數(shù)學(xué)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。 Mechanical design。 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(shù) ................................................................................................................................ 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(shè)計(jì)計(jì)算方法 ....................................................................................................................... 5 建立設(shè)計(jì)模型 ............................................................................................................................................. 5 設(shè)計(jì)思路 ..................................................................................................................................................... 5 設(shè)計(jì)流程及流程圖 ..................................................................................................................................... 5 設(shè)計(jì)流程 .............................................................................................................................................. 5 設(shè)計(jì)的框圖 ......................................................................................................................................... 6 具體的設(shè)計(jì)及計(jì)算過程 ............................................................................................................................ 8 確定計(jì)算功率 ..................................................................................................................................... 8 帶型號的選取 ..................................................................................................................................... 8 帶速的計(jì)算 ......................................................................................................................................... 9 初定中心距的范圍 ...........................................................................................................................10 帶長的計(jì)算及基準(zhǔn)長度的選取 ......................................................................................................10 中心距和包角的計(jì)算 ........................................................................................................................10 包角的驗(yàn)算 ....................................................................................................................................... 11 帶根數(shù)的確定 .................................................................................................................................... 11 軸上載荷的確定 ...............................................................................................................................12 確定帶輪的結(jié)構(gòu) ........................................................................................................................
