摘要
齒輪是機(jī)械裝備制造業(yè)中典型系列化零件，擺線齒輪在機(jī)械裝備中常應(yīng)用于各種減速器中。長期以來，盡管擺線齒輪已經(jīng)系列化，但是由于實(shí)際應(yīng)用中所需要的齒輪型號、規(guī)格存在差異，齒輪的設(shè)計(jì)、生產(chǎn)仍以訂制為主，其設(shè)計(jì)效率較低。三維CAD技術(shù)的發(fā)展推動著齒輪設(shè)計(jì)也在向集成化、自動化、智能化方向發(fā)展。
本文以擺線齒輪為研究對象，使用SolidWorks三維設(shè)計(jì)軟件，通過參數(shù)化建模方法，生成擺線齒輪的完整擺線齒廓，采用特征操作方法生成了擺線齒輪的三維實(shí)體模型。然后建立SolidWorks與VB的接口，將模型導(dǎo)入。在VB編譯器中實(shí)現(xiàn)了擺線齒輪的參數(shù)化設(shè)計(jì)，實(shí)現(xiàn)了CAD技術(shù)與CAE技術(shù)的一體化。
參數(shù)化設(shè)計(jì)方法是一種通過改變圖形某一部分或某幾部分的尺寸，通過尺寸驅(qū)動自動完成對圖形相關(guān)部分的改動。當(dāng)前齒輪的設(shè)計(jì)計(jì)算過程仍然沿用傳統(tǒng)的手工計(jì)算方法，嚴(yán)重影響齒輪設(shè)計(jì)的總體效率。另外，當(dāng)前齒輪三維建模過程還存在齒廓精度低等問題。
本文所設(shè)計(jì)開發(fā)的擺線齒輪參數(shù)化設(shè)計(jì)系統(tǒng)對于推動擺線齒輪和減速器設(shè)計(jì)效率的提升具有重要意義。減速機(jī)及擺線齒輪的設(shè)計(jì)與制造技術(shù)關(guān)系著國家基礎(chǔ)機(jī)械工業(yè)水平，開拓和發(fā)展減速機(jī)及擺線齒輪技術(shù)具有廣闊的前景。
參數(shù)化設(shè)計(jì)方法對于形狀大致相似的一系列零部件是行之有效的設(shè)計(jì)方法，只需要給定齒輪的相關(guān)參數(shù)就可以生成新的零部件，從而大大提高設(shè)計(jì)效率，縮短生產(chǎn)周期。利用SolidWorks三維設(shè)計(jì)軟件可以有效提高設(shè)計(jì)質(zhì)量，縮短設(shè)計(jì)周期。開發(fā)一套實(shí)用的擺線齒輪參數(shù)化設(shè)計(jì)系統(tǒng)具有十分現(xiàn)實(shí)的意義。

ABSTRACT

The function of this design is to finish a gear parametrical three-dimensional modeling design system which is based on SolidWorks. Its design objects are involute straight tooth and helical tooth cylinder gear wheel. The functions of this system designed is to automatically finish parametrical three-dimensional modeling of involute straight tooth and helical tooth cylinder gear wheel in the environment of SolidWorks software. In this design, it introduces that it takes SolidWorks with three-dimensional mechanical modeling design software as basis, and uses Visual Basic as the exploitation implement, the fundamental method of calling API function to actuate the further development of SolidWorks and uses this method to realize gear parametrical three-dimensional modeling design according to parameters input by users.The development of gear parametrical design and modeling software brings about the join of gear parametrical design and three-dimensional substance modeling ,shortens the time of design produce ,and benefits the improvement of produce quality. The methods of determinations of geometrical dimensions is referred to "China Mechanical Design Handbook", and the softwares used in this design include Microsoft Visual Basic 6.0, AutoCAD2006, and SolidWorks 2006. This system is developed and debugged in windows XP, and it is indicated that this system can be run normally.

Keywords: SolidWorks; Further development of solidworks; Visual basic; Parameterical design of gear wheel
