I 毕业设计( 论文) 题目: 自动攻丝机设计摘要本文主要进行的是自动攻丝机设计,该自动攻丝机在普通的小台式钻床机床上进行设计,设计机床得主传动变速系统时首先利用传动系统设计方法求出理想解和多个合理解。根据数控机床主传动系统及主轴功率与转矩特性要求,分析了机电关联分级调速主传动系统的设计原理和方法。从主传动系统结构网入手,确定最佳机床主轴功率与转矩特性匹配方案,计算和校核相关运动参数和动力参数。本说明书着重研究机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。关键词: 分级变速;传动系统设计;传动副;结构网;结构式;齿轮模数;传动比 III Abstract First, in order to obtain the ideal and more understanding of the design method of transmission system design of machine tool transmission system when the winner. According to the requirements of the main drive system C machine tool and spindle power and torque characteristics, analysis of the design principle and method of mechanical and electrical connection and speed of main transmission system. Starting from the main drive system work, determine the optimum matching scheme of machine tool spindle power and torque characteristics, the calculation and verification of relevant motion parameters and dynamic parameters. Design steps and design method of this specification focuses on the main drive system of machine tool, according to the motion parameters have been determined by transmission center distance of expansion graph of the minimum as the goal, formulate transmission scheme transmission system, in order to obtain the optimal scheme and high design efficiency. In the main drive system of machine tool, in order to reduce the number of gears, simplify the structure, reduce the axial size, design method of the number of gear teeth is trial, join algorithm, design calculation of trouble and isnot easy to find a reasonable. Through the research and analysis of the main drive system of triple slide gear characteristics, draw the part drawing and the spindle box expansion plan and section view.
