Abstract

The utility model provides a bearing seal cover of a heavy duty roller, relating to a technical field of a roller structure of a roller conveyor, which has good sealing performance and strong reliability, and guarantees flexibility and service life of the bearing. The technical scheme is that the bearing seal cover of the heavy duty roller includes a steel pipe, a bearing, a shaft, and a plastic cover; the plastic cover is pressed on the outer end surface of the bearing; the outer rim of the plastic cover is pressed on a convergent inner wall of the steel pipe; the inner rim of the plastic cover is attached to the outer circular surface of the shaft; and the plastic cover is characterized by including an inner cover and an outer cover, wherein the inner end surface of the outer cover is nested on the outer end surface of the inner cover.

Description

A kind of bearing felt lid of heavy roller

Technical field

The utility model relates to the roller frame technical field of roller conveyor, is specially a kind of bearing felt lid of heavy roller.

Background technology

Heavy roller mainly is used on the conveyer of mine, and working environment is more abominable, to the seal request height of dustproof and waterproof.The dustproof and waterproof structure of existing heavy roller is seen Fig. 1, its outer face at bearing 2 installs a vinyl cover 6 additional, the outer rim of vinyl cover 6 press-fits in the closing in face of steel pipe 1, the periphery of the inner edge applying axle 3 of vinyl cover 6, its shortcoming is: shortcoming: along with the long-time rotation of heavy roller, the plastics cover of dust is outer easily to be moved, and exposes the slit, foreign material such as dust, water enter bearing the inside, alerting ability and life-span that influence is rotated easily.

Summary of the invention

At the problems referred to above, the utility model provides a kind of bearing felt lid of heavy roller, its good airproof performance, good reliability, the alerting ability and the life-span of having guaranteed bearing.

A kind of bearing felt lid of heavy roller, its technical scheme is such: it comprises steel pipe, bearing, axle, vinyl cover, the outer face of described bearing is pressed with described vinyl cover, the outer rim of described vinyl cover press-fits the closing in inwall in steel pipe, the periphery of the inner edge applying axle of vinyl cover, it is characterized in that: described vinyl cover comprises inner cap, enclosing cover, the nested outer face that is loaded on described inner cap of described enclosing cover inner end surface.

It is further characterized in that: the outer rim of described enclosing cover press-fits in the closing in face of described steel pipe, the periphery of the Inner edge applying axle of described enclosing cover, the fit internal face of described steel pipe of the outer rim of described inner cap, the fit axial periphery of Inner edge of described enclosing cover of the Inner edge of described inner cap, the inner end surface of described inner cap press-fits the outer face in described bearing.

After adopting structure of the present utility model, owing to used enclosing cover, inner cap, it has formed two layers of airtight protection, and the nested outer face that is loaded on inner cap of enclosing cover inner end surface, make connection closely, reliably, firmly, and then make good airproof performance, the good reliability of bearing felt lid, the alerting ability and the life-span of having guaranteed bearing.
