Abstract
A bearing includes an inner ring having an inner raceway, an outer ring having an outer raceway, rolling elements located between the inner raceway and the outer raceway and a cage for holding the rolling elements. A diameter Dr of the rolling elements satisfies Dr≤0.35*(H1−H2), where H1 is an outer diameter of the outer ring, and H2 is an inner diameter of the inner ring, and a relative groove curvature Ri of the inner raceway satisfies 0.52≤Ri≤0.58, and/or a relative groove curvature Re of the outer raceway satisfies 0.53≤Re≤0.58.
Claims18
A bearing comprising:
- an inner ring having an inner raceway;
- an outer ring having an outer raceway;
- rolling elements located between the inner raceway and the outer raceway;
- and
- a cage for holding the rolling elements;
- wherein a diameter Dr of the rolling elements satisfies Dr≤0.35*(H1−H2), where H1 is an outer diameter of the outer ring, and H2 is an inner diameter of the inner ring;
- and
- a relative groove curvature Ri of the inner raceway satisfies 0.52≤Ri≤0.58, and/or a relative groove curvature Re of the outer raceway satisfies 0.53≤Re≤0.58.
A method for applying a lubricating oil to a bearing, comprising:
- immersing the bearing in the lubricating oil, the bearing including an inner ring with an inner raceway, an outer ring with an outer raceway, rolling elements located between the inner raceway and the outer raceway, a cage for holding the rolling elements, and a seal;
- and
- performing centrifugal drying operation on the bearing;
- wherein a diameter Dr of the rolling elements satisfies Dr≤0.35*(H1−H2), where H1 is an outer diameter of the outer ring, and H2 is an inner diameter of the inner ring;
