摘要升降机主要应用于高空照明装置安装与维修，主要用于体育馆等高大场所，解决高空作业引发的各种不便，节省了人力物力，在智能化的未来有很好的发展前景。

设计的凸轮式升降机包括电机、齿轮减速机构，和凸轮机构，绕线机构和线控电路几部分。它的工作原理是通过电机驱动，经过减速机构，由斜齿轮改变转动方向，利用盘式凸轮实现导线轮往复的匀速直线运动，解决绕线问题。在设计原理基础上，计算传动比、电机功率及钢丝绳速度和总长，进行总体结构设计，并对传动机构进行动力学分析，校核关键零部件的强度，利用soildworks软件进行三维设计与装配，然后进行动画仿真，最后利用AutoCAD软件绘制升降机装配图与主要零件的零件图，用于加工制造。61556

Title   The design of disc cam type two elevator     

Abstract The lift is mainly applied to the installation and repair of high-altitude lighting device, mainly used for solve the high altitude operation stadium and other large venues, it save manpower and material resources, also it have good development prospects in the future of intelligent. Cam lift design including motor, gear, and a cam mechanism, a winding mechanism and a control circuit part. Its working principle is driven by the motor, the reducer, the gear change the direction of rotation, using cam to achieve the wire wheel reciprocating uniform motion in a straight line solve the problem as coiling line.

The design principle, calculation of transmission ratio, power of motor and the wire rope speed and length, overall structure design, and the transmission mechanism for dynamic analysis, checking the strength of key parts, using three-dimensional design and assembly, and then animated simulation, finally draw assembly drawing and the main parts of elevator by using AutoCAD software parts diagram, used in the manufacturing process.
