CHAPTER 5 PLANAR LINKAGE MECHANISMS
5.1 INTRODUCTION
Have you ever wondered what kind of mechanism causes the windshield wiper on the front window of car to oscillate (FIG.5-1a)?The mechanism,shown in Fig.5-1b,transforms the rotary motion of the motor into an oscillating motion of the windshield wiper.
Let’s make a simple mechanism with similar behavior.Take some cardboard and make four strips as shown in FIG.5-2a.
Take 4 pins and assemble them as shown in FIG.5-2b.
Now,hold the 6in.strip so it can’t move and turn the 3in.strip.You will see that the 4in.strip oscillates.
第五章 平面连杆装置
5.1 介绍
你有没有想过什么样的装置使得挡风玻璃上的雨刷左右摇摆(图5-1a)?图5-1b所示装置把马达的旋转动作转换成雨刷的摇摆动作.
让我们制作一个简单的类似装置.取一些纸板,如图5-2a所示制作成4条纸片.
取四根图钉,如图5-2b所示把这4条纸片组装起来.
现在,以手捏住6英吋长的纸片,固定不动,然后转动3英吋长的纸片.你将会看到4英吋长的纸片开始摇摆.
