一、刮研的目的通过刮研,使轴瓦与轴的接触面积和单位面积上的接触点数达到接触精度要求,以保证轴与轴瓦的顺利跑合,延长使用寿命。二、刮研前的准备工作除了刮研工具、吊具及其它用品要准备好外,为了不因铜瓦衬与钢套孔的间隙而造成铜瓦研坏和“起皮”,还必须保证铜瓦衬与钢套孔、机身孔等的装配完全贴合无缝,并有一定过盈量。
First, the purpose of scraping through scratching and grinding, the bearing pads and the shaft contact area and contact area per unit area to reach the contact accuracy requirements to ensure the smooth running shaft and bearing to extend the service life. Second, scraping before the preparatory work In addition to scraping tools, spreaders and other supplies to be prepared, in order not to bronze lining and steel sleeve hole caused by the gap between the copper tile grinding bad and “peeling”, but also must ensure Copper lining and steel sleeve hole, fuselage holes and other assembly completely fit seamless, and a certain amount of interference.
