设计简介
摘 要
本设计为三面翻广告牌的设计，三面翻广告牌是由一组并排的三棱柱组成，三棱柱可由铝型材制成，且可围绕自身中心轴转动，将三种广告画面分别设置在改组三棱柱的三个面上，从而利用三棱柱的三个侧面可形成三副画面，转动三棱柱即可变换广告画面。
本文介绍了三面翻广告牌传动系统方案，能够实现多种翻动效果，达到成本低，维护简易，设计中主要运用了间隙机构的特点，将主动件的均匀转动转换为时动时停的周期性运动，省去不需要的能量的浪费，充分利用了机械的功用。同时完成了三面翻广告牌传动系统中关键零部件的结构参数设计，包括传动部件的设计，轴的设计与校核，电机的选择等。运用CAD软件完成了三面翻广告牌结构装配图与相关零件图，并尽可能地运用Pro/e软件对三面翻广告牌传动系统进行三维造型设计。

Abstract
This design for the design of the three billboards, three billboard is composed of a set of side by side of triangular prism, triangular prism can be made out of aluminum, and turning around its central axis, the three kinds of advertising images respectively set on the reorganization of tri-prism three, thus using tri-prism three sides can form three pairs of pictures, turn the triangular prism can transform advertising images.
Three billboards transmission system are introduced in this scheme, can achieve a variety of flipping effect and achieve low cost, easy maintenance, mainly used in the design of the characteristics of the clearance agency, will take the initiative to stop when a uniform rotation transformation is still cyclical movement, save unnecessary waste of energy, make full use of the function of the machine.and completed the three drive system of the billboard structure parameter design of key parts, including the design of the driving part, the design of the shaft and check, the choice of motor, etc. Using CAD software to complete the three billboard structure assembly and related parts graph, and as far as possible using Pro/e software to three billboards transmission system for three-dimensional modelling design.
Key words: Three sides、intermittent mechanism、transmission parts 、 CAD
