1、越野车车架强度的有限元分析汽车差速器壳体设计[文档在线提供]摘要差速器壳是汽车差速器的一个主要零件，它使差速器及其部件中的轴、轴承、套和齿轮等零件按一定的相互位置关系装配成一个整体，并按预定传动关系协调其运动。首先，根据图纸分析零件的技术要求和难加工方面,零件类型的可以确定毛坯的材料和铸件余量及形状,然后分析加工工艺选择粗细基准以及拟订工艺过程。通过上述分析选择工艺装备。对两种工艺方案进行优化选择，使工艺方案更加完善。此零件有些尺寸需要专用量具，所以需要设计专用的孔轴量具，对零件进行机械加工时，为保证工件加工精度，先要保证工件在机床上占有正确的位置

2、，然后通过夹紧机构使工件在正确位置上固定不动，这一任务就是由机床夹具完成，此钻孔夹具也需要专用夹具，通过对专用夹具知识的理解，对定位误差与加工误差的分析，采用标准件和设计其他专用零部件。关键词：差速器壳，工艺，夹具ABSTRACTDifferentialcarrierisamajorautomobileparts,itmakesdifferentialandtheircomponentsintheshaft,bearings,gearsandothersparepartskitsandthelocationofcertainmutualrelati
