在机械制造业中,我们经常遇到将两个衬套或轴承压入一个支座内孔里。由于装配室间及其方向都有限。这样,不仅给装配工作带来很大麻烦,而且难以保证衬套对准座孔和顺利地压入。针对这种情况,我们采用以如图所示的衬套安装工具。它由一个带台肩的心轴和一个卡圈组成。心轴滑合在衬套内孔中,借以定心起导向作用;其上特制台肩与卡圈相吻合,以便传递压力作用。其长度能满足将两个衬套压入座孔内。
In the machinery manufacturing industry, we often encounter the two bushings or bearings pressed into a bearing bore. As the assembly room and its direction are limited. This not only causes great inconvenience to the assembly work, but also makes it difficult to ensure that the bushing is aligned with the seat hole and smoothly pressed in. In this case, we use a bushing installation tool as shown. It consists of a mandrel with a shoulder and a collar. Spindle sliding in the bushing in the hole, so as to guide the role of centering; on its special shoulder and collar coincide, in order to transmit pressure. Its length can meet the two bushing pressed into the seat hole.
