大型転がり軸受。1. An outer ring and an inner ring incorporated inside the outer ring,
In a large rolling bearing incorporating rolling elements between its two wheels, a plurality of outer ring segments and a plurality of inner ring segments are provided by dividing the outer ring and the inner ring along a plane perpendicular to the axis and a plane along the axis. , The abutting surfaces at the circumferential ends of a plurality of outer ring segments and the abutting surfaces at the circumferential ends of a plurality of inner ring segments located on the same plane,
Move the rolling elements of each segment by shifting their positions in the circumferential direction with respect to the abutting surfaces at the circumferential ends of the outer ring segments and the abutting surfaces at the circumferential ends of the inner ring segments on other planes aligned in the axial direction. A large-sized rolling bearing characterized in that recesses are provided at both ends of a guide raceway surface, and an outer ring segment and an inner ring segment arranged in an axial direction are connected by fastening bolts.
