机床主传动系统设计的运动设计和动力设计

摘要

主传动系统设计是机床设计中非常重要的组成部分，本次设计主要由机床的级数入手，于结构式、结构网拟定，再到齿轮和轴的设计，再选择各种主传动配合件，对轴和齿轮及配合件进行校核，将主传动方案“结构化”，设计主轴变速箱装配图及零件图，侧重进行传动轴组件、主轴组件、变速机构、箱体、润滑与密封、传动轴及滑移齿轮零件的设计，完成设计任务。

关键词：机床、主传动系统、结构式。

Abstract

Main drive system design is Very important part of the Machine Design,The design of the series to start primarily by machine,In the structure, the structure network developed, to the design of gears and shafts,Choose a variety of main drive with the pieces of the shaft and gear, and checked with the parts ，design and motive of completion sport spread the lord to move the project\spare parts diagram and lay particular emphasis on to carry on spread to move stalk module, principal axis module and become soon organization, box a body, lubricate and seal completely, spread to move stalk and slippery move wheel gear spare parts of design to complete design tasks.

【Keywords】lather, Main drive system,Structure.

引言

机床的主传动系统的布局可分成集中传动和分离传动两种类型。

主传动系统的全部变速结构和主轴组件集中装在同一个箱体内，称为集中传动布局；传动件和主轴组件分别装在两个箱体内，中间采用带或链传动，称为分离传动布局。
