解放牌汽车曲轴后轴承,是用以支承变速器第一轴的。它的过渡配合装入曲轴的后端,拆卸很困难。过去,我们在换取这个轴承时,都是采用撬杠撬,这样不仅工作效率低,而且劳动强度大,有时会造成事故。我们在实际工作中自制了一个简易拉具,经试验使用效果很好。这种简易拉具的结构如图1所示。拉具由凸形支架2、弹性薄壁涨圈4(零件尺寸见 Jiefang card crankshaft rear bearings, is used to support the transmission of the first axis. Its transition fit into the rear end of the crankshaft, disassembly is difficult. In the past, we used the crowbar pry for this bearing, which was not only inefficient but also labor-intensive, sometimes causing accidents. We made a simple pull in the actual work, the test results are good. The structure of this simple pull as shown in Figure 1. Pull by the convex stent 2, thin elastic ring 4 (see the parts size
