摘要本次设计主要是对普通卧式升降台铣床的主轴箱的设计，设计的内容包括运动设计，动力设计，结构的设计。 在运动设计中，根据给定的机床参数，用途，分析典型工艺的切削用量，拟定传动方案，确定结构形式，画转速图，并演算转速误差，画传动系统图，计算带轮直径和齿轮齿数。在动力设计中，根据电动机功率，确定各传动件的计算转速，估算各轴经，齿轮模数，确定齿轮结构尺寸；完成装配草图后，验算主要传动件的刚度和寿命。其中对主轴箱中的主轴做了详细的设计。在结构设计中主要对传动轴系，变速机构，主轴组件，操纵机构，换向和制动装置，箱体，润滑和密封等的布置和结构进行设计，然后将各主要零件的图绘制出来。关键词：主轴箱，机构，齿轮，模数。Abstract The design is a horizontal platform for ordinary milling machine spindle box design, the design includes campaign design, power design, structural design. Design in motion, according to a given machine parameters, uses, analysis of a typical cutting process, the development of transmission to determine the structural form, map drawing speed, and speed calculation error, painting transmission map, calculate the diameter of pulley and gear teeth . Design power, according to motor power, transmission case to determine the calculation of the speed estimated by the shaft, the gear module to determine the size of gear; the completion of the assembly after the draft, check the stiffness of the main transmission case and the life. One of the main axis of the spindle box design in detail. In the structural design of the main line of the shaft, speed change mechanism, the spindle components, manipulation of institutions, and for the brake, tank, such as lubrication and sealing of the layout and structure design, and then all the major mapping out parts . Key words: spindle box, institutions, gears, modulus目录摘要........................................................................IAbstrac...
