Oil film bearing and bushing

An oil film bearing for a rotating roll neck in a rolling mill, said bearing comprising:

• sleeve segments received on and fixed relative to the roll neck for rotation therewith, said sleeve segments being aligned axially to define a cylindrical journal surface of the roll neck and having adjacent ends located intermediate the ends of said journal surface;
• a bushing having a cylindrical internal bearing surface surrounding said journal surface, said bushing being contained by and fixed within a bearing chock;
• inlet means for introducing a continuous flow of oil between said journal surface and said bearing surface at locations which allow the thus introduced oil to be formed hydrodynamically by the rotary motion of said journal surface relative to said bearing surface into an oil film on which the journal surface is carried at a load zone on one side of the bearing;
• and outlet means for continuously removing oil from said load zone at a location intermediate to the ends of said bushing and aligned radially with the adjacent ends of said sleeve segments, thereby providing an interruption in the load carrying continuity of the hydrodynamically formed oil film and separating said load zone into compound pressure zones.
