One side of the bearing seat is provided with a sealing groove, and one side of the dust cover is provided with a sealing convex ring matched with the sealing groove. An inner sealing ring and an outer sealing ring are arranged between the dust cover and the bearing, and the inner sealing ring and the outer sealing ring are both provided with ladder-shaped structures. The roller shaft is also provided with a step check ring which is matched with the step structure.
Further, the right side of the bearing is also provided with an inner dustproof check ring.
Further, a sealing rubber is installed in the sealing groove. The sealing convex ring is clamped into the sealing groove, sealing rubber can increase sealing performance, and dust is prevented from entering the carrier roller from the edge of the dust cover.
Further, a fine sealing ring is arranged between the dust cover and the stepped retainer ring. The function of the fine sealing ring is to improve the sealing performance of the round hole in the center of the dust cover.
The utility model also comprises other components which can enable the carrier roller sealing structure of the belt conveyor to be used normally, and all the equipment or components adopt the conventional technical means in the field. In addition, the devices and components not defined in the present utility model are all conventional in the art, such as bearings in the present utility model. In the implementation process, a proper equipment or component model can be selected according to a specific working scene.
The working principle of the utility model is as follows: when the dustproof cover is installed, the sealing convex ring on the dustproof cover is clamped into the sealing groove of the bearing seat, sealing rubber can increase sealing performance, and dust is prevented from entering the carrier roller from the edge of the dustproof cover. The center round hole of the dust cover is provided with a fine sealing ring, so that the dust cover has a sealing effect. Meanwhile, an inner sealing ring and an outer sealing ring are arranged inside the bearing seat. In addition, the step check ring is matched with the step structures of the inner sealing ring and the outer sealing ring, so that the tightness is further improved.
Compared with the prior art, the utility model has the following beneficial effects: the carrier roller has good sealing performance: the sealing convex ring, the sealing groove, the step retainer ring and other structures are arranged, so that the sealing performance of the carrier roller is improved, and the use cost is greatly reduced.
