In order to solve the technical problems, the technical scheme provided by the utility model is as follows: the utility model provides a dustproof sealed bearing, includes inner circle, outer lane, support frame, its characterized in that: a plurality of rolling grooves are formed in the support frame, and balls are arranged in the rolling grooves in a rotating mode; the inner side of the outer ring and the front side and the rear side of the outer ring are respectively provided with an annular limiting groove, sealing plates are respectively arranged in the limiting grooves, each sealing plate is provided with a flow guiding structure, each flow guiding structure comprises an annular groove respectively arranged on each sealing plate, a plurality of flow guiding grooves are circumferentially arranged on each sealing plate and are respectively communicated with the annular grooves, and the inner bottom surfaces of the flow guiding grooves are respectively inclined outwards from one end close to the annular groove to the other end.
As an improvement, a groove capable of accommodating the supporting frame is formed on the outer side of the inner ring; the inner middle end of the outer ring is provided with a second groove capable of accommodating the inner ring.
As an improvement, the grooves and the grooves are both annular.
As an improvement, the sealing plates are in opposite directions.
As an improvement, through grooves are formed in the inner ring and the sealing plate, and the inner diameters of the through grooves are the same.
Compared with the prior art, the utility model has the advantages that: sealing plates are arranged on two sides of the outer ring, so that gaps among the inner ring, the support frame and the outer ring can be shielded, and dust entering is reduced;
the sealing plate is embedded into the outer ring and is rotationally connected with the outer ring, so that normal operation of the bearing is not affected, and dust can be further reduced due to embedded;
the sealing plate is provided with the diversion trench, so that dust can be concentrated in the diversion trench when the dust floats, the dust is prevented from floating, and the dust is convenient to clean in a concentrated mode.
Drawings
Fig. 1 is a schematic structural view of the present utility model.
Fig. 2 is an exploded view of the present utility model.
As shown in the figure: 1. the ball bearing comprises an inner ring, 2, an outer ring, 3, a supporting frame, 4, rolling grooves, 5, balls, 6, grooves, 7, second grooves, 8, limit grooves, 9, sealing plates, 10, annular grooves, 11 and diversion grooves.
Detailed Description
The present utility model will be described in further detail with reference to the accompanying drawings.
In the first embodiment, referring to fig. 1 and 2, a dust seal bearing includes an inner ring 1, an outer ring 2, and a supporting frame 3, where a groove 6 capable of accommodating the supporting frame 3 is provided on the outer side of the inner ring 1; the middle end of the inner part of the outer ring 2 is provided with a groove II 7 which can accommodate the inner ring 1, and the groove 6 and the groove 7 are both annular, so that the support frame 3 can rotate in the inner ring 1 and the outer ring 2 and is not easy to fall off under the limitation of the groove 6 and the groove II 7; the bearing is characterized in that a plurality of rolling grooves 4 are formed in the support frame 3, balls 5 are arranged in the rolling grooves 4 in a rotating mode, and two ends of each ball 5 are respectively connected with the inner ring 1 and the outer ring 2 in a rotating mode, so that the bearing can work normally; annular limiting grooves 8 are formed in the inner side of the outer ring 2 and located on the front side and the rear side, sealing plates 9 are arranged in the limiting grooves 8, and the directions of the sealing plates 9 are opposite.
