This INNOVATION PATENT discloses a rolling bearing with high heat dissipation property, 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. Thickness of the outer ring is larger than that of the inner ring. A ladder surface is set up at both sides of the outer ring, respectively. The first heat dissipation cover is set up on the front end surface of outer ring. The second heat dissipation cover is set up on the rear end surface of outer ring. The first heat dissipation cover owns the first heat dissipation groove. The first heat dissipation groove is set up annularly. The mounting hole corresponding to the inner ring is set up at the central position of the second heat dissipation cover. The second heat dissipation groove is set up on the surface of the second heat dissipation cover. The second heat dissipation groove is set up annularly. This device has high heat dissipation property and can avoid heat accumulation on the rolling body and improve service life. |
