Abstract

U型接头是一种新颖的、简单可靠的联接方式。由开口夹套、锥形套、螺栓、螺母及垫圈所组成;适用于U型物体与物体之间的联接。

Description

本发明主要用于U形物体与物体之间的联接。
在我们的日常工程设计中,U形物体与物体之间都是以螺栓与螺母、销(包括标准的或非标准的)、轴以及其它形式的联接。这几种型式都起到了联接物体之功能,得到了广泛的应用。现在,我们提供一种新颖的、简单可靠的联接方式-U形接头。这种接头不需要配合,装卸方便,具有较广的实用价值。
这种U形接头由开口夹套、锥形套、螺栓、螺母及垫圈所组成。
本发明将通过下列实施例并结合图作进一步的说明。
图1是本发明的装配示意图。如图1所示,U形物10有两个径向间隔U形的支臂11、12,联接物20装在U形支臂的中间,并用螺栓50穿过开口夹套30,锥形套40及垫圈70并用螺母60将其拧紧。
为了消除U形物10与联接物20之间的横向移动,我们在开口夹套30中采用了如图2所示的那样:开口夹套30由两个部份所组成,即柱形套筒31与凸肩32。
如图2所示,开口夹套30中的柱形套筒31,其内径略大于螺栓的外径,其外径略小于相应的孔21的内径,使其相对应的轴、孔之间形成了紧密的滑动配合。另外,开口夹套30中的凸肩32其内径如剖视图3所示为一个锥面,即由里向外逐渐扩展,其外径略小于孔15的内径。
如图2所示,开口夹套上的三条开口槽33,其长度对于凸肩32可贯通于全长,对于柱形套筒31其长度为联接物20的厚度 或略长些。
如图2所示,开口夹套30中的柱形套筒31的长度等于或略小于U形物支臂11与联接物20臂厚之和,开口夹套30中的凸肩32的长度等于或略小于U形物中支臂12的厚度。
为了联接,将联接物20插入U形支臂11、12之间的径向间隔中,使其联接物20上的孔21与U形支臂上的孔13、15在同一轴线上。因此,开口夹套30穿过对准孔13、15、21从U形支臂右边的外面插入,直到凸肩32的轴向内端面支撑在联接物20的相邻侧面上。把锥形套40(如图4所示其锥形套的外锥面与开口夹套内表面的锥面相对应)插入开口夹套30中的内锥面,与之相吻合,然后将螺栓从右侧插入,一直插过开口夹套30,最后垫上垫圈70,用螺母60拧紧。
如图1所示,在拧紧螺母60时,螺栓50对锥形套40施加径向内在压力,使开口夹套30产生径向左移动,从而把联接物20固定在U形支臂11的右侧面14上,同时使开口夹套30的三个开口槽33产生径向向外扩张,从而对U形支臂孔15及联接物20产生预加荷载。这样就导致了预加荷载将联接物20固定在U形物支臂11的右侧面14上,从而消除了U形物10与联接物20之间的横向移动。另外,开口夹套30中的三个开口槽33的径向向外扩张会在U形物支臂孔15及联接物20上产生预应力,从而防止了联接物20的移动,以使疲劳损坏减少到最小程度。
此外,开口夹套30上的槽孔一般为三条,可根据情况开成两条或六条等,开口夹套30的壁厚一般考虑为1-3毫米。
综上所述,本发明具有很高的实用价值,对防止和消除联接物 的横向移动,径向转动起到了一定的作用。另外,它可以搞成与螺栓相配套使用的标准件,使其标准化,系列化,以满足不同孔径,不同物体联接的需要。
