三面翻广告牌传动系统设计
摘要：户外广告是一种典型的城市广告形式，随着社会经济的发展，户外广告已不仅仅是广告业发展的一种传播媒介手段，而是现代化城市环境建设布局中的一个重要组成部分。本设计为三面翻广告牌的传动系统，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，实现非单一的翻动效果，并完成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：Outdoor advertising is a typical urban forms of advertising, with the social and economic development, outdoor advertising is not only the development of the advertising industry as a means of mass media, but the layout of modern urban environment is an important component. The design for the three billboards in the transmission system, three billboards side by side by a group composed of three prism, triangular prism can be made of aluminum, and can rotate around its central axis, the three ad screens were set up in the restructuring of The three prism surface to take advantage of the three prism can be formed three pictures side, turn the prism to change advertising display.
 This article describes three billboards drive solution that can achieve a variety of flip effects, to achieve non-single flip effects, and complete the three billboards drive the structural parameters in the design of key components, including the design of transmission components, the axis design and verification, motor selection. The use of CAD software to complete the structure of the three billboards assembly drawing and related parts diagram, and the use of Pro / e software, three billboards on the three-dimensional drive system design.
