数控车床主转动系统机构设计

摘要

本文作者研究的主要是数控车床的主传动系统，这类主传动系统的设计可用

于对普通车床的改造，以适应当前我国机床工业发展的现状，具有一定的经济效
益和社会效益。

本文作者完成的设计主要包括根据一些原始数据（其中包括机床的类型、规格

等）结合实际条件和情况对车床一些参数进行拟定，再根据拟定的参数，进行传
动方案的比较，确定传动方案。然后计算各传动副的传动比及齿轮齿数，再估算齿
轮的模数和各轴的轴径，并对齿轮和轴的强度、刚度进行校核。除此之外，还要对
箱体内的主要结构进行设计，一些零件的选型，如电磁离合器的选择等，从而完
成对整个主传动系统的设计。

Abstract

What author of this text study numerical control main transmission of lathe mainly,

the main design of transmission can use for to ordinary transformation of lathe, In order to
adapt to the current situation of the present industrial development of lathe of our country,
have certain economic benefits and social benefit.

The design that the author of this text finished includes according to some initial

data mainly( type, specification of including the lathe ,etc.) Combine actual condition and
situation draft to some parameters of lathe, and then according to the parameter drafted,
Carry on the comparison of the transmission scheme, confirm the transmission scheme. It
then can't calculate every transmission transmission of the packs than and gear wheel tooth
count, estimate modulus and the every axle foot-paths of axle of gear wheel more, And
