河南科技学院 2009届本科毕业论文（设计） 论文题目：小型自发电照明系统-手压式发电机构系统设计 学生姓名： 所在院系： 机电学院 所学专业： 机械设计制造及其自动化 导师姓名： 完成时间： 摘 要 随着各种器件对供电电源的长时间供电和结构小型化的要求日益迫切，而物理电源具有无损检测、可重复使用、可长期储存和良好的高低温特性，又由于高性能永磁体的出现，使得微型自发电电源受到了广泛的关注。 本文讨论了机械能供电系统及如何用手摇发电机来对可储电池进行充电，从而带动LED灯泡进行日常照明的工作原理，成为照明系统的电力源。首先阐述了充电电路设计，LED发光原理，发电机构材料选择，发电机构的设计，及齿轮的参数计算，以二级增速传动为机械转换机构。动力将从手柄传至原动系，带动发电机运转。 发电机是一种微型的直流发电机，通过对转子的转动速度来计算此发电系统最终能产生多大功率和提供多大供电电压，将计算结果和实际上所能产生的功率和电压作比较，分析各种影响关系，得出制作此微型自发电系统的最佳设计尺寸。 关键词：机械转换机构，发电机，LED，充电电路 Abstract With the power supply device for a long period of power supply and the demands of small-scale structure of the increasingly urgent, and the physical power of nondestructive testing, re-use, it can be a good long-term storage and high and low temperature properties, and because high-performance Wing The emergence of magnet, making micro-generating power since it has been widely concern. This paper discusst machine ability power supply system and how by hand shake generator to come to rightness can keep battery to carry on refresh, arouse a LED lamp bulb to carry on thus daily illuminate of work principle, become lighting system of electric power source.Elaborated to refresh an electric circuit design first, the LED gave out light principle, generate electricity organization material a choice and generate electricity organization of design, and the parameter of the wheel gear calculation, with second class increase to soon spread to move for machine conversion organization.The motive will spread from the hand handle to original move to fasten, arouse generator an operation. Generator is a miniature DC generator, through the rotational speed of the rotor to calculate the ultimate power generation system can produce much more power and supply voltage, and the calculated results can actually have the power and voltage for comparison and analysis all kinds of influences, that produced this micro-power generation system since the best design dimensions.
