Abstract

The present invention relates to a non-locating bearing arrangement (6) for supporting one side of a trunnion ring of a converter. The arrangement comprises a toroidal roller bearing (20) mounted in a split housing (30), which has a top half and a bottom half. An inner ring (21) of the bearing is fixedly mounted to a trunnion (4) of the trunnion ring. An outer ring (22) of the bearing is mounted to a bore of the housing (30). To prevent rotation of the outer ring relative to the housing, the arrangement further comprises a locating element (70), which has a main body part (71) and a protrusion (72) that extends in a radially inward direction. The main body part of the locating element is accommodated within a recess within the housing and has a plane of symmetry that coincides with a centre plane (30a) through the housing. The protrusion is adapted to fit in a lubrication hole provided in the outer ring at an axially central location thereof. To fix the axial position of the bearing outer ring relative to the housing centre plane, the bearing arrangement further comprises first and second spacer rings (61, 62) mounted in axial abutment between respective first and second side parts (31, 32) of the housing and opposing end faces of the outer ring. According to the invention, the first and second spacer rings (61, 62) have different axial widths (s1, s2) and the protrusion (72) has a plane of symmetry that is parallel to and axially offset from the housing centre plane (30a) by an amount (y) equal to half of the difference in axial width between the first and second spacer rings.
