Abstract
An inner ring has a plurality of grooves which are formed on its inner peripheral face and extended from an end thereof in an axial direction. The grooves are extended from both ends in the axial direction of the inner ring inwardly in the axial direction, and closed in a middle part in the axial direction of the inner peripheral face of the inner ring. The grooves are formed in plurality at an equal interval in a circumferential direction.
Claims7
A bearing device including:
- an inner ring;
- an outer ring;
- and
- rolling elements arranged between the inner ring and the outer ring, the inner ring being assembled to an inside member by fitting, or the outer ring being assembled to an outside member by fitting, wherein:
- one of a fitting face of the inner ring which is fitted to the inside member, a fitting face of the inside member which is fitted to the inner ring, a fitting face of the outer ring which is fitted to the outside member, and a fitting face of the outside member which is fitted to the outer ring is formed with a plurality of grooves which are extended inwardly in an axial direction from an end of the fitting face and which are arranged in a circumferential direction;
- and
- the grooves are extended from both ends in an axial direction of the fitting face and closed in a middle part in the axial direction of the fitting face.
