微机变幅机构设计系统

Microcomputer aided design system for luffing mechanism

本文介绍适合微机使用的单臂架绳索补偿变幅机构设计系统的系统目标,系统模块结构图,模块功能,数据组织和处理。本系统已用于三个不同吨位小型门座起重机的设计。文章最后以制动轮联轴器装配图为例,对绘图系统的建立和二次开发进行了说明。

This paper introduces the system objective, modular structure diagram, modular function, data organization and processing of a microcomputer aided design system applicable to single boom luffing mechanism with rope compensation. The system has been used in the design of three light duty portal cranes with different lifting capacity. At the end of the paper the formation and development of the drafting system are described on the example of the assembly drawing of a brake coupling.
