连杆机构

1、- 1 - 连杆机构 连杆存在于车库门装置，汽车擦装置，齿轮移动装置中。它是一给予很少关注的机械工程学的组成部分。 联杆是具有两个或更多运动副元件的刚性机构，用它的连接是为了传递力或运动 。在每个机器中， 在运动期间，联杆或者占据一相对于地面的固定位置或者作为一个整体来承载机床 。这些连杆是机器主体被称为固定连杆。 基于由循环的或滑动的分界面的元件连接的布局被称作连接 。 这类旋转的和菱形的连接机构被称作低副 。 高副基于接触点或弯曲分界面的 。低 副的例子包括铰链循环的轴承和滑道以及万向接头 。高 副的例子包括通。

8、附录连杆机构连杆的作用是将活塞承受的力传给曲轴，并使活塞的往复运动转变为曲轴的旋转运动。连杆由连杆体、连杆盖、连杆螺栓和连杆轴瓦等零件组成，连杆体与连杆盖分为连杆小头、杆身和连杆大头。连杆小头用来安装活塞销，以连接活塞。连杆大头与曲轴的连杆轴颈相连。一般做成分开式，与杆身切开的一半称为连杆盖，二者靠连杆螺栓连接为一体。连杆轴瓦安装在连杆大头孔座中，与曲轴上的连杆轴颈装和在一起，是发动机中最重要的配合副之一。常用的减磨合金主要有白合金、铜铅合金和铝基合金。连杆机构中两端分别与主动和从动构件铰接以传。

9、曲柄连杆机构曲柄连杆机构是往复式内燃机的主要工作机构。曲柄连杆机构是发动机实现工作循环，完成能量转换的主要运动零件。在作功冲程，它将燃料燃烧产生的热能活塞往复运动、曲轴旋转运动而转变为机械能，对外输出动力；在其他冲程，则依靠曲柄和飞轮的转动惯性、通过连杆带动活塞上下运动，为下一次作功创造条件。曲 柄 连 杆 机 构 的 功 用曲 柄 连 杆 机 构 的 作 用 是 提 供 燃 烧 场 所 ， 把 燃 料 燃 烧 后 气 体 作 用 在 活 塞 顶上 的 膨 胀 压 力 转 变 为 曲 轴 旋 转 的 转 矩 ， 不 断 输 出 动 力 。 （ 1） 将 气 体 。
