湖北民族学院理学院 2014 届本科毕业论文( 设计) 高楼逃生装置设计学生姓名: 学号: 专业: 答辩时间: 指导老师: 评阅老师: I 摘要本文设计的高楼逃生装置是利用负反馈闭环系统原理实现自减速功能, 是一种不需要使用任何能源的纯机械装置。为了使该装置的体积小、重量轻、结构紧凑,以便于放置和使用。本文对该装置主要的零件、机构进行优化设计和校核。然后通过计算验证可知该装置的自减速功能可以实现,能够使逃生人员以一个安全速度抵达地面。关键词:高楼逃生装置,负反馈闭环系统原理,纯机械装置 II Abstract The high-rise escape device designed herein is the use of the principle ofa negative feedback loop to achieve self-deceleration function .It isa purely mechanical device without using any energy. To make the device small, light, compact, and facilitate placement and use. Herein, the main part and mechanism of the device to optimal design and check. Then verified by calculation shows that the self-deceleration function of the device can be achieved, enabling the escape personnel ata safe speed reach the ground. Keywords: The high-rise escape device , The principle ofa negative feedback loop , The purely mechanical device 目录摘要··································································································· I Abstract ·································································································· II 1绪言 课题的背景及研究意义·········································································· 1 国内外研究现状··················································································· 1 高楼逃生装置的类型············································································· 2 内凸轮式高楼逃生装置······································································· 2 涡轮蜗杆式高楼逃生装置···································································· 3 心摩擦式高楼逃生装置······································································· 4 2设计方案的确定 方案设计原理······················································································ 6 设计方案的优缺点················································································ 8 3逃生装置各部件设计 轴的设计···························································································· 9 主动轴的设计···············
