小型整体箱体三维造型及数控加工工艺

江西科技学院本科生毕业论文（设计）AbstractGear drive is the most widely used modern machinery.It is a speed reducercomposed of gear,shaft,bearing and box body,motivation and work for the originalmachine or actuator,matching speed and torque transfer function.The gear reducer ischaracterized by high efficiency,long service life,convenient maintenance,so it iswidely used.The design process and its CAD/CAM design the design on thetransmission --two cylindrical gear reducer machinery.Firstly,the development oftransmission scheme selection for V band and the coaxial two cylindrical gear reducerfor transmission device,then the device and V reducer design calculation the choiceof motor,V design,gear design,shaft design,selection and checking the couplingstructure,selection of the key and check and bearing lubrication etc.)planar design ofgear reducer using AutoCAD software,and the assembly drawing finished drawing ofgear reducer 2D part drawing.The 3D Proe drawing assembly reducer and CAMdesignKeywords:drive shaft;transmission ratio;transmission efficiency of CADV/CAM
