The bearing body 6 is installed inside the flange body 1, and then the retaining ring 5 is installed inside the flange body 1 to perform rotary sealing on the inner ring of the bearing body 6. At this time, the retaining ring 5 seals between the bearing body 6 and the flange body 1, and does not need to rely on the self-sealing of the bearing, which is convenient for the maintenance of the bearing flange;

[0025] On one side of the two retaining rings 5 in opposite directions, a first sealing groove 7 is opened, a second positioning ring 4 is inserted into the first sealing groove 7, a second sealing groove 8 is opened on both sides of the flange body 1, and a first positioning ring 3 is inserted into the second sealing groove 8. A rubber gasket 2 is bonded to one side of the flange body 1. When it is necessary to connect two flange bodies 1, first insert the first positioning ring 3 into the second sealing groove 8, insert the second positioning ring 4 into the first sealing groove 7 on the retaining ring 5, and then when aligning and installing the two flange bodies 1, make the first positioning ring 3 also insert into the second sealing groove 8 on the other flange, and make the second positioning ring 4 insert into the first sealing groove 7 on the other retaining ring 5, and then fix the two flanges, so as to seal the gap between the two flanges and improve the sealing performance of the connection of the bearing flange.

[0026] In the present utility model, symmetrically distributed fourth sealing grooves 11 are formed on both sides of the first sealing groove 7. Second sealing rings 12 for sealing between the second positioning ring 4 and the retaining ring 5 are adhesively bonded in the two fourth sealing grooves 11 to ensure the sealing performance between the second positioning ring 4 and the retaining ring 5. Two third sealing grooves 9 are formed on both sides of the second sealing groove 8, and the multiple third sealing grooves 9 are symmetrically distributed. First sealing rings 10 for sealing between the first positioning ring 3 and the flange body 1 are adhesively bonded in the multiple third sealing grooves 9 to ensure the sealing performance between the first positioning ring 3 and the flange body 1. The depth of the second sealing groove 8 is greater than that of the first sealing groove 7.

[0027] The working principle of this embodiment: During use, the bearing body 6 is installed inside the flange body 1, and then the retaining ring 5 is installed inside the flange body 1 to perform rotational sealing between the retaining ring 5 and the inner ring of the bearing body 6. At this time, the retaining ring 5 seals between the bearing body 6 and the flange body 1, eliminating the need to rely on the self-sealing of the bearing itself, which facilitates the maintenance of the bearing flange. When connecting two flange bodies 1, first insert the first positioning ring 3 into the second sealing groove 8, and insert the second positioning ring 4 into the first sealing groove 7 on the retaining ring 5. Subsequently, when aligning and installing the two flange bodies 1, insert the first positioning ring 3 into the second sealing groove 8 of the other flange, and insert the second positioning ring 4 into the first sealing groove 7 of the other retaining ring 5. Then fix the two flanges, thereby sealing the gap between the two flanges and improving the sealing performance of the bearing flange connection.

Sealing gaskets 13 are adhesively bonded to one side of the first sealing ring 14 and the second sealing ring 15, and the sealing gaskets 13 are flush with the end faces of the flange body 1 and the retaining ring 5. Bevels are provided on one side of the first sealing ring 14 and the second sealing ring 15 close to the sealing gaskets 13. Insert the second sealing ring 15 into the first sealing groove 7, and insert the first sealing ring 14 into the second sealing groove 8. Subsequently, when connecting the flange to other articles, the sealing gaskets 13 on the first sealing ring 14 and the second sealing ring 15 seal the gap between the flange and other articles. At the same time, due to the bevels on the first sealing ring 14 and the second sealing ring 15, the sealing gaskets 13 will be deformed by extrusion during connection, thereby better sealing the gap between the flange and other articles and improving the use effect of the flange bearing.

[0030] Working principle of this embodiment: When connecting the flange to other articles, insert the second sealing ring 15 into the first sealing groove 7, and insert the first sealing ring 14 into the second sealing groove 8. Subsequently, when connecting the flange to other articles, the gaskets 13 on the first sealing ring 14 and the second sealing ring 15 will seal the gap between the flange and other articles. At the same time, due to the inclined surfaces on the first sealing ring 14 and the second sealing ring 15, the gasket 13 will be squeezed and deformed during connection, so as to better seal the gap between the flange and other articles, improving the use effect of the flange bearing.
