1、JIUJIANGUNIVERSITY毕业设计题目电风扇摇头机构设计英文题目designheadofelectricfan院系机械与材料工程学院专业机械设计制造及自动化姓名练锋军年级2010(机A1011)指导教师刘良文潘旭红二零一四年六月摘要电风扇摇头装置设计是从电风扇设计开始的,也是电风扇设计中最重要的部分,对于电风扇的研究,国内外已有不少的研究成果,但在创新这一块做的还不够,还有待进一步完善。本文首先对摇头电风扇的历史和发展现状以及其类型和特点进行了介绍,然后介绍了设计准则,提出方案拟定,并选择最优方案,主要是现有的电风扇摇头装置中平面摇杆机构,包括平
2、面摇杆机构的结构、工作原理、设计原理、设计原则;其次根据已知原动机的转速,分配传动比,选择合适的机构,如蜗轮蜗杆机构以及齿轮机构,根据传动比确定它们的基本参数,设计计算几何尺寸,再次采用图解法,根据已知条件(极位夹角,摇杆速度等)设计平面四杆机构,然后在实验室组建仿真机构模型,观察所设计的尺寸是否满足所需的运动轨迹,再就制作台式电风扇摇头平面机构的计算机动态演示,通过图解法研究各杆件的运动,进行运动分析,最后总结并讲述了电风扇的未来展望。关键词:平面摇杆机构,传动比,蜗轮蜗杆,齿轮传动,运动分析,动态演示viAbstractThedesignofthesh
