Description

Technical Field

[0001] The utility model belongs to the technical field of bearings, in particular to a tapered roller bearing with a sealing function. Background Art

[0002] Tapered roller bearings are a commonly used mechanical component, mainly used to bear combined radial and axial loads. The rollers of this type of bearing are tapered, so they can distribute the load more effectively and allow a certain tilt angle between the shaft and the bearing. The current tapered roller bearings are composed of a ring, a cage and its rolling elements, and then a layer of seals is covered on the surface. However, most tapered roller bearings and seals are integrated. When the seals are worn during long-term use, it is difficult to replace them in time, resulting in a decrease in the sealing effect of the tapered roller bearing, and even foreign matter may enter the bearing. Utility Model Content

[0003] In order to overcome the above-mentioned defects, the utility model provides a tapered roller bearing with a sealing function, which solves the problem that most tapered roller bearings and seals are integrated, and it is difficult to replace the seals in time when they are worn during long-term use, resulting in a decrease in the sealing effect of the tapered roller bearing and even foreign impurities may enter the interior of the bearing.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a tapered roller bearing with a sealing function, comprising a bearing body, a lower sealing ring clamped under the bearing body, an upper sealing ring clamped on the bearing body, an L-shaped plate clamped outside the bearing body, a column connected to the lower sealing ring, a clamping groove provided in the bearing body, a positioning groove provided on the upper sealing ring, a through hole provided in the positioning groove, a threaded rod rotatably connected in the L-shaped plate, a turntable connected under the threaded rod, a positioning block externally threaded on the threaded rod, and the column clamped in the positioning block.

[0005] As a further solution of the utility model: the L-shaped plate is clamped in the lower sealing ring, and a groove is provided in the L-shaped plate.

[0006] As a further solution of the utility model: the column is clamped in the clamping groove, and the positioning block is clamped in the upper sealing ring.

[0007] As a further solution of the utility model: a slide groove is provided in the positioning block, and a movable plate is slidably connected in the slide groove.

[0008] As a further solution of the utility model: the movable plate is clamped in the column, the column is provided with bolts, and the movable plate is connected to the column through the bolts.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] 1. The tapered roller bearing with sealing function is provided with an L-shaped plate, a positioning block, a column, a slot, a positioning groove, a through hole and a threaded rod. When the lower sealing ring is overlapped at the bottom of the bearing body, the column will be interlaced with the slot, and when the upper sealing ring is overlapped at the top of the bearing body, the column will be interlaced with the through hole. When the L-shaped plate is clamped in the slot, the threaded rod is driven to rotate by a turntable, and the positioning block is clamped in the positioning groove after moving on the surface of the threaded rod. The tapered roller bearing can realize the function of rapid assembly of the lower sealing ring and the upper sealing ring with the bearing body through the cooperation between the positioning block, the column and the threaded rod. When the lower sealing ring and the upper sealing ring are worn out due to long-term use, they can be replaced in time, thereby ensuring the sealing effect of the tapered roller bearing and preventing foreign matter from entering the bearing.

[0011] 2. The tapered roller bearing with sealing function is provided with a slide groove, a movable plate and bolts. When the column and the positioning block are interlaced, a thrust is applied to the movable plate. When the movable plate slides in the slide groove, it will be stuck in the column, and the column will be connected to the movable plate with standard bolts, thereby improving the stability of the lower sealing ring and the upper sealing ring after they are fixed, and avoiding the lower sealing ring and the upper sealing ring from loosening during use.

[0019] The L-shaped plate 4 is clamped in the lower sealing ring 2, and a groove 5 is provided in the L-shaped plate 4. By providing the groove 5, when the L-shaped plate 4 is clamped in the clamping groove 8, the column 7 will be clamped in the groove 5, so that the groove 5 plays a certain positioning role for the column 7, avoiding collision between the column 7 and the L-shaped plate 4;

[0020] A positioning groove 9 is provided on the upper sealing ring 3, a through hole 10 is provided in the positioning groove 9, a threaded rod 11 is rotatably connected in the L-shaped plate 4, a turntable 12 is connected under the threaded rod 11, the threaded rod 11 is externally threadedly connected to a positioning block 6, and the column 7 is clamped in the positioning block 6. By setting the positioning groove 9, when the positioning block 6 moves in the L-shaped plate 4, the positioning block 6 will be clamped in the positioning groove 9, so that the positioning groove 9 plays a certain auxiliary role for the positioning block 6, so that the positioning block 6 can be completely fitted with the upper sealing ring 3;

[0021] The column 7 is clamped in the clamping groove 8, the positioning block 6 is clamped in the upper sealing ring 3, a sliding groove 13 is provided in the positioning block 6, and a movable plate 14 is slidably connected in the sliding groove 13. By setting the column 7, when the lower sealing ring 2 and the upper sealing ring 3 are connected with the bearing body 1, the column 7 above the lower sealing ring 2 is inserted with the bearing body 1 and then clamped with the upper sealing ring 3, so that the column 7 plays a certain limiting role in the fixation of the lower sealing ring 2 and the upper sealing ring 3, and avoids the position of the lower sealing ring 2 and the upper sealing ring 3 from being offset when being fixed;

[0022] The movable plate 14 is clamped in the column 7, and a bolt 15 is provided in the column 7. The movable plate 14 is connected to the column 7 through the bolt 15. By setting a slide groove 13, when a thrust or a pull is applied to the movable plate 14, the movable plate 14 will slide in the slide groove 13, so that the slide groove 13 plays a certain guiding role for the movable plate 14, thereby avoiding the movable plate 14 from being dislocated when moving.

[0023] The working principle of the utility model is:

[0024] When the tapered roller bearing is in use, the lower sealing ring 2 can be overlapped under the bearing body 1, and the column 7 above the lower sealing ring 2 will be interlaced with the slot 8. When the upper sealing ring 3 is overlapped on the top of the bearing body 1, the column 7 will be interlaced with the through hole 10. When the L-shaped plate 4 is clamped in the slot 8, the column 7 will be clamped in the groove 5, and then the threaded rod 11 is driven to rotate by the turntable 12, and the positioning block 6 will move on the surface of the threaded rod 11. When the positioning block 6 is clamped in the positioning groove 9, it will be interlaced with the column 7, and then after applying thrust to the moving plate 14, it will slide in the slide groove 13. After the moving plate 14 is interlaced with the column 7, it is connected by bolts 15.
