1、摘要齒輪作為最重要的基礎(chǔ)傳動(dòng)部件被廣泛地應(yīng)用于機(jī)械、冶金、石化、煤炭、水電等行業(yè)。在齒輪設(shè)計(jì)和生產(chǎn)過程中,需要大量的分析、計(jì)算和繪圖工作。隨著計(jì)算機(jī)技術(shù)的飛速發(fā)展，使齒輪設(shè)計(jì)人員借助計(jì)算機(jī)及相應(yīng)軟件可迅速、高效、準(zhǔn)確地進(jìn)行設(shè)計(jì)方案的確定、比較、分析和繪圖，為生產(chǎn)企業(yè)以高技術(shù)、高質(zhì)量、低成本占領(lǐng)市場提供技術(shù)保障。本文論述了利用VB6.0作為開發(fā)工具，調(diào)用SolidworksAPI函數(shù)對Solidworks進(jìn)行二次開發(fā)，實(shí)現(xiàn)精確漸開線直齒圓柱齒輪參數(shù)化設(shè)計(jì)，同時(shí)以插件的形式實(shí)現(xiàn)了與Solidworks軟件的無縫集成，從而提高了齒輪三維造型的速度和效率。利用參數(shù)化設(shè)計(jì)生成的齒輪實(shí)體，另存為
2、IGS格式文件導(dǎo)入ANSYS軟件，根據(jù)齒輪的工作情況及失效形式,建立有限元分析模型,對齒根最大彎曲應(yīng)力有限元分析。最后利用IGS格式文件生成的MCX格式文件，在MastercamX4軟件中利用數(shù)控加工自動(dòng)編程技術(shù)對齒輪齒廓進(jìn)行數(shù)控線切割加工指令程序的編制，并進(jìn)行數(shù)控加工仿真。本論文在solidworks平臺上實(shí)現(xiàn)精確漸開線直齒圓柱齒輪的參數(shù)化三維設(shè)計(jì)的方法和過程，對同類零件的快速設(shè)計(jì)具有一定的借鑒意義。關(guān)鍵詞:精確漸開線直齒圓柱齒輪VBSolidwork二次開發(fā)有限元分析數(shù)控加工仿真AbstractAsthemostimportantfoundationoftransmissionc
