本设计着重研究卧式铣床主传动系统的设计步骤和设计方法，根据已确定的运动参数以变速箱展开图的总中心距最小为目标，拟定变速系统的变速方案，以获得最优方案以及较高的设计效率。在机床主传动系统中，为减少齿轮数目，简化结构，缩短轴向尺寸，用齿轮齿数的设计方法是试算，凑算法，计算麻烦且不易找出合理的设计方案。本文通过对主传动系统中三联滑移齿轮传动特点的分析与研究，绘制零件工作图与主轴箱展开图及剖视图。

The design focuses on the design steps and design method for horizontal milling machine main drive system, according to the movement determined parameters to the gearbox developed view of the total center distance as the objective, to develop the program shift transmission system to obtain the optimal solution as well as more high design efficiency. In the machine tool main drive in order to reduce the number of gear structure is simplified, shorter axial dimension, with the gear design approach is a spreadsheet, hash algorithm to calculate cumbersome and difficult to find a reasonable design. Based on the main drive system features triple sliding gear analysis and research, working drawings and drawing parts headstock developed view and a sectional view.
