Detailed Description
As shown in fig. 3 and 4, the seal ring type tapered bearing for a motorcycle comprises an inner gasket 1, an outer gasket 3, a retainer 2 and a plurality of cylindrical rollers 4; the retainer 2 is conical, a plurality of roller slot holes 20 are formed in the conical surface of the retainer 2 along the circumferential direction, and the cylindrical rollers 4 are arranged in the roller slot holes 20 of the retainer in a matching manner; the outer surface 11 of the inner gasket 1 is conical, the upper end of the inner gasket 1 is provided with an upper limit edge 12, the lower end of the inner gasket 1 is provided with a lower limit edge 13, and the cylindrical roller 4 is arranged between the upper limit edge 12 and the lower limit edge 13 in a matching manner, so that the cylindrical roller 4 cannot move in the axial direction; the retainer 2 is arranged at the periphery of the inner gasket 1, the inner surface 30 of the outer gasket 3 is conical, the outer gasket 3 is arranged at the periphery of the retainer 2, so that the retainer 2 is clamped between the inner gasket 1 and the outer gasket 3, one side of the cylindrical roller 4 is in line contact with the inner surface 30 of the outer gasket 3, and the other side of the cylindrical roller is in line contact with the outer surface 11 of the inner gasket 1; when the device works, the inner gasket 1 and the retainer 2 rotate along with the rotating shaft. Because the inner gasket 1 and the retainer 2 are matched to form a conical space for placing the cylindrical rollers, all the cylindrical rollers 4 form a conical shape, and the conical bearing with the structure has firm structure and good stability.
In order to improve the sealing performance of the tapered bearing, the present invention is provided with a seal ring cover 5 on one side of the retainer, as shown in fig. 1 and fig. 2, the seal ring cover is composed of an inner seal ring cover 52 and an outer seal ring cover 51, wherein the outer seal ring cover 51 is formed by compounding a metal ring sheet 510 and a rubber ring sleeve 511, as shown in fig. 2, the rubber ring sleeve 511 is formed by pouring rubber on the outer ring of the metal ring sheet 510 to form the side wall of the outer seal ring cover 51; the inner gasket cover 52 is made of metal, and the inner gasket cover 52 is compounded on the bottom of the metal ring plate 510 through rubber, so that a complete gasket cover 5 is formed, wherein the inner gasket cover 52 of the gasket cover 5 covers the inner gasket 1, and the outer gasket cover 51 of the gasket cover 5 covers the outer gasket 3. Because the inner sealing ring 52 and the inner gasket 1 are both made of metal materials, the inner sealing ring 52 can be firmly fixed on the inner gasket 1, and the rubber ring sleeve 511 of the outer sealing ring cover 51 is made of rubber, so that the outer gasket 3 can be sealed, dust particles can not enter the retainer 2, and the bearing can run for a long time.
In order to prevent the metal ring piece 510 from being corroded, the rubber ring cover 511 extends to and covers the upper surface of the metal ring piece 510. The rubber portion covering the upper surface of the metal ring piece 510 can effectively isolate the contact between the outside atmosphere and the metal ring piece 510, thereby prolonging the service life of the seal ring cover.
In order to reduce the contact area between the cylindrical roller 4 and the inner pad 1, the middle of the outer surface 11 of the inner pad 1 has a protrusion 10, and the outer surface of the protrusion 10 is tapered. Because the outer surface of the inner gasket 1 is only partially in contact with the cylindrical rollers 4, the friction force is smaller and the performance is better. Also in order to reduce the friction between the cylindrical roller 4 and the upper limiting edge 12 of the inner pad 1, the present invention is provided with a shallow groove 40 (as shown in fig. 5) in the upper surface of the cylindrical roller 4. Due to the shallow groove 40, on the premise of not affecting the quality of the cylindrical roller 4, the contact area between the upper surface of the cylindrical roller 4 and the upper limiting edge 12 of the inner gasket 1 can be effectively reduced, so that the friction force between the upper surface of the cylindrical roller 4 and the upper limiting edge 12 is smaller, and the bearing performance is further ensured.
Finally, it is worth mentioning that in order to support the cylindrical roller 4 more firmly, the lower end of the cage 2 of the present invention extends towards the inside with a support edge 21. The supporting edge 21 and the lower limiting edge 13 of the inner gasket 1 always support the cylindrical roller 4, so that the installation firmness of the cylindrical roller 4 is effectively enhanced, and the stability and reliability of the bearing are ensured.
