摘 要
首先，设计机床的主传动变速系统，应该利用传动系统的设计方式得出假设结果和最终结果。根据数控机床主传动系统，转矩特性和主轴功率，分析了机电关联分级调速主传动系统的设计方法。从主传动系统结构网入手，确定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。本说明书着重研究主传动系统的设计步骤和方法，根
据已确定的运动参数，以变速箱展开图的中心距最小为目标，拟定变速系统的变速方案，来获得最优方案。设计主传动系统时，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齿轮传动特点的分析，从而绘制零件图与装配图。 关键词：传动系统，传动副，齿轮模数，传动比
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 of CNC 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 structure network, 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 is not 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.
Key Words: the transmission system design, network structure, the module of gear,
transmission ratio
