在修理Д—54和Д—35柴油发动机时,常常要更换下大量的轴瓦。这些更换下来的轴瓦,可以利用铅青铜合金层塑性变形的方法来修复。修复的方法:即在清洗乾净的轴瓦磨损面上,压出深的麻面(压出很多深的小坑——译者)根据瓦片的磨损情况况,压出很深的麻面,或将合金完全穿透,或者只作局部的麻面加工。在进行麻面加工时,压陷处周围的合金便稍为突起,这样就减少了瓦片的内径。然后,将瓦片镀锡,浇上白合金,再依照通常的方法进行铣瓦。用上述方法缩小了内径的瓦片,其表
When repairing the Д-54 and Д-35 diesel engines, it is common to replace a large number of bearings. These replace the bearing, can use the method of plastic deformation of lead-bronze alloy layer to repair. Repair method: that is, clean the bush wear surface, the pressure of the deep pockmarked (out of a lot of deep pits - translator) According to the wear and tear of the tile situation, out of the deep pockmarked surface, Or completely penetrate the alloy, or only for the local Ma face processing. In the process of pitting, the alloy around the depression will be slightly raised, thus reducing the inner diameter of the tile. Then, the tiles tinned, poured white metal, and then according to the usual method of milling tile. With the above method to reduce the inner diameter of the tile, the table
