ZH1100柴油机齿轮室盖多孔钻组合机床总体及左主轴箱设计
摘 要：本课题设计一台柴油机齿轮室盖的钻削组合机床，主要完成机床总体和左主轴箱的设计工作。根据被加工零件确定加工孔的数量、位置、切削用量及主轴类型，拟订了主轴箱的传动路线，应用最优化方法布置齿轮，确定传动参数，设计轴的结构，进行齿轮、轴等相关零件的强度校核计算。针对该传动系统中部分零部件进行具体的结构设计和力学分析。为确保加工精度，采用“一面两销”的定位方案；为实现无级调速，安全可靠，选择液压滑台；根据零件的大小及被加工孔的位置确定主轴箱的轮廓尺寸；由加工工艺选择滚珠轴承主轴，通过计算扭矩确定主轴和传动轴的直径；齿轮的模数是通过类比法确定； 齿轮齿数和中间传动轴的位置是由“计算、作图和多次试凑”相结合的办法确定；计算主轴、传动轴的坐标并进行中心距验算，确定部分轴上需采用变位齿轮；轴上的齿轮套、键等零件按轴号选取相应的标准件。在设计之中，尽量选用通用件，可以减少了制造成本，增加了经济效益。

the Overall and Left Headstock Spindle Design of Drilling
Modular machine for gear chamber cover of ZH1100 diesel engine
Abstract: This project is to design a modular machine tool for manufacturing the gear chamber cap of diesel engine. Main work is the design of overall and the left headstock. Based on the processed spares , the number、the position and the machining data of the holes and the form of the principal axis are determined , the driving route of the headstocks are drawn, the cogwheels are disposed by the methods of optimization, the driving parameter are determined, the structure of the principal axis is designed and the strength of the parts, like the gears and the axises, are checked . In order to guarantee the processing precision, the localization plan use "two sells and a surface". In order to implement the stepless speed regulation, safe is reliable, choice hydraulic pressure sliding table. According the size of components and the position of the hole ,that is processed to set the overall size of the headstock. Choicing ball bearing spindle by processing craft. The spindle and drive shaft diameter is decided through computation torque. The gear modulus is decided through the correlation method. The gear mentions and the position of intermediate propeller shaft is decided by the means " computation, mapping and tries to collect many times". Calculates the coordinates of the spindle and drive shaft and checking the center distance, determined department
