<p>This INNOVATION PATENT discloses a modified bearing device, including the inner ring, outer ring, rolling body and holder. The inner ring is set up in the outer ring. The inner ring and the outer ring are set up coaxially. The rolling body is connected between the inner ring and the outer ring. At least 5 rolling bodies are set up annularly. The holder is used to connect the rolling bodies in turn. The holder is annular. Several locating rings to locate the rolling bodies are set up annularly on the holder. Location holes are set up in the locating rings. At least 3 contact points are annularly set up at the hole wall of location holes. The contact point is hemispheric and contacts the rolling body. Small frictional drag exists between the holder and the rolling body. During rotation in the inner ring, friction coefficient between the inner ring and the outer ring reduces. This indirectly improves rotation efficiency of inner ring.</p> |
