显然，为了完成电风扇的摆动运动，需要达到以下运动功能要求: （1）风扇需要根据运动规律左右摆动，因此需要相应的摆动机构被设计. （2）风扇需要改变传动轴并改变速度电风扇摇摆结构，因此有必要设计相应的齿轮系机构. 对这两种机构的运动功能的进一步分析表明，它们应该实现以下基本运动: （3）左右摆动有三种基本运动: 运动轴变换，传动比减小和周期性摆动. （4）有一个基本动作可以改变运动轴并改变传动比: 运动轴改变. 另外，还需要满足传动性能要求: 改变电风扇的送风面积时，在速回系数K = 1.015，摆角φ= 85°的要求下，尽量保持平滑的运动过渡并减少各机构之间的摩擦. 运动功能图1.3原始数据和设计要求1.3.1原始数据风扇直径为φ300mm，风扇电机转速n = 1450r / min，风扇摇头扬程T = 10s. 风扇摆动角Ψ= 85°，快速返回系数k = 1.015. 2020年4月19日，本文档仅供参考1.3.2设计要求台式电风扇的摇头装置的设计要求其必须符合给定的快速返回系数和摆动角度，以实现左右摆动动力下风扇叶片旋转和摇头的组合运动. 1.4设计任务1.根据给定的主要参数，制定机械传动系统的总体计划. 2.绘制绘制机制的动作.
