BUSHING FOR BEARING ON OIL LAYER FOR ROLLING MILL Russian patent published in 2004 - IPC

FIELD: mechanical engineering. SUBSTANCE: bushing has inner conical section, end section mounted coaxially with inner conical section, and outer cylindrical surface, enclosing said inner conical section. Said outer cylindrical surface is made with capability of mounting with rotation in bearing cylinder and has a diameter D of at least 500 mm. Inner conical section is made with capability of mounting of roll neck on outer conical section and has obliquity angle of more than three degrees and minimal thickness of approximately 10 mm to 0.024D+14.5 mm. Cotter pin grooves are made outside inner conical section exclusively on end section for preventing rotation of bushing on rolling neck. Certain level of resilient deformation of bushing causes increase of bushing and oil layer contact area in support load area. EFFECT: increases possible support load. 3 cl, 6 dwg
