■ Scraping and grinding of copper tile
Centrifugal sliding bearings of low-speed and heavy-duty equipment are difficult to form complete liquid lubrication, but are in mixed lubrication state and belong to non-liquid friction bearings. The bearing bush is usually 180 or 120 degrees. The bearing bush with scraped spherical bush back is buckled on the journal for research. The surface roughness Ra1 of Journal of Journal of journal bearing is generally 0.8 micron. After careful scraping, the surface roughness of bearing bush can be considered as Ra2=3.2 micron, and the smoothness is higher after proper operation. Although the surface roughness and surface shape errors of the scraped bearing bush are relatively large, the bearing bush material is white alloy or bronze, which has good adaptability to the journal, so the influence of them can be ignored.
