陕西理工学院毕业设计论文两级展开式圆柱齿轮减速器的数字化设计与传动件制造[摘要]随着科学技术和国民经济的发展，渐开线圆柱齿轮传动减速器的需求量越来越大，质量要求也越来越高，传统的减速器设计方法己不能满足用户的需求，CAD/CAM技术的迅速发展使得它无论在机械、电子、航空、建筑等领域都获得了成功的应用。这对于提高产品性能和质量、缩短产品开发周期、降低成本和增强市场竞争力起了巨大的作用。参数化设计模型是以约束来表达产品模型的形状特征，以一组参数来控制设计结果，从而能通过变换一组参数值方便地创建一系列形状相似的零件。参数化设计的基本手段有程序驱动与尺寸驱动。程序驱动法是通过分析图形几何模型的特点，确定模型的主参数以及各尺寸间的数学关系，将这种关系输入程序中，进而在零件设计时只要输入几个参始值就可生成所要求的模型。尺寸驱动是对程序驱动的扩展，它的基本思想是由应用程序生成所涉及的基图，该图的尺寸有一系列的标识，这些尺寸由用户在编程时输入或交互式输入，从而生成用户模型。[关键词]齿轮减速器参数化设计运动仿真传动件制造SecondaryexpansionofthenumberofcylindricalgearreducerdesignandmanufactureoftransmissionpartsAbstract：Alongwiththescienceandtechnologyandthenationaleconomydevelopment,theinvolutecylindricalgearstransmissionreductiongeardemandismoreandmorebig,thequalityrequirementmoreandmoreisalsohigh,traditionalreductiongeardesignmethodoneselfcannotsatisfytheuserthedemand,theCAD/CAMtechnologyrapiddevelopmentcausesitregardlessofindomainsandsoonmachinery,electron,aviation,buildinghasallobtainedthesuccessfulapplication.Thisregardingenhancedproductperformanceandquality,thereductionproductdevelopmentcycle,reducesthecostandstrengthensthemarketcompetitivepowertoplaythehugerole。Theparameterizationdesignmodelisexpressestheproductmodelbytherestrainttheshapecharacteristic,byagroupofparametercontroldesignresult,thuscanthroughtransformgroupofparametervaluestofoundaseriesofshapesimilarcomponentsconveniently.Theparameterizationdesignessentialmethodhastheprocedureactuationandthesizeactuation，Theprocedureactuationlawisthroughtheanalysisgraphgeometrymodelcharacteristic,definitemodelmainparameteraswellasduringvarioussizesmathematicalrelation,thiskindofrelationsinputroutinein,thenwhencomponentsdesignsolongasinputsthemodelwhichseveralsenateinitialvaluesmayproducerequest.，Thesizeactuationistotheprocedureactuationexpansion,itsbasicthoughtisthebasechartwhichinvolvesbytheapplicationprocedureproduction,thischartsizehasaseriesofmarking,thesesizesbyuserwhenprogramminginputsortheinteractiveinput,thusproductionuser'smodel。Keywo
