Title:
BEARING SUPPORTING STRUCTURE
Document Type and Number:
Japanese Patent JP2019163842
Kind Code:
A
Abstract:
To prevent rotation of an inner ring to a shaft member in a bearing supporting structure for rotating and supporting the shaft member by a rolling bearing in which the inner ring is split in a circumferential direction.SOLUTION: A shaft member 30 has a fitting portion 32 to which a rolling bearing 10 is externally fitted, and the fitting portion 32 has non-complete round shape on a cross section of a direction orthogonal to a center axis m. The rolling bearing 10 includes an inner ring 13 split into two in a circumferential direction, an outer ring 11 split into two in a circumferential direction and fixed to a radial outer part of the inner ring 13, and a plurality of rolling elements 15. An inner periphery of the inner ring 13 has the shape corresponding to an outer periphery of the fitting portion 32, and has a non-complete round shape on a cross section of a direction orthogonal to a center axis m. Rotation of the inner ring 13 to the shaft member 30 is prevented by restricting radial displacement of the inner ring 13.SELECTED DRAWING: Figure 3
