Abstract
The utility model relates to a shield bearing which comprises an inner ring, an outer ring, holders and rollers. The rollers are connected between the inner ring and the outer ring through the holders. The shield bearing further comprises dust covers. A plurality of clamp grooves are arranged on two sides of the inner surface of the outer ring along the radial direction. Elastic buckles are connected with the clamp grooves in matched mode and arranged on the outer edges of the dust covers. The dust covers are connected with the clamp grooves through the elastic buckles in clamping mode. A working gap is arranged between the inner edges of the dust cove and the inner ring. Annular grooves are arranged on two sides of the outer surface of the inner ring close to the inner edges of the dust covers in the radial direction. Seal rings are arranged in the annular grooves. The shield bearing has the advantages of being simple in structure, convenient to manufacture and low in manufacturing cost, having a dustproof function so as to protect normal operation of the bearing and being suitable for working in a high-dust environment.
