Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of self-aligning roller bearings, specifically a wear-resistant self-aligning roller bearing. Background Technology
[0002] Self-aligning roller bearings have double rows of rollers, with one common spherical raceway on the outer ring and two raceways on the inner ring that are inclined at an angle relative to the bearing axis. In addition to radial loads, this bearing can also withstand bidirectional axial loads.
[0003] Existing self-aligning roller bearings have relatively complete structure and function, and can meet basic usage requirements, but the following problems still exist:
[0004] In actual use, significant friction is generated when the outer ring rotates with the self-aligning rollers and the inner ring rotates with the self-aligning rollers. As the frequency of use increases, this friction leads to increased wear, which in turn increases the wear rate of the self-aligning rollers and reduces the overall service life of the bearing. Utility Model Content
[0005] (a) Technical problems to be solved
[0006] To overcome the aforementioned deficiencies of the prior art, this utility model provides a wear-resistant self-aligning roller bearing, which solves the problem that in actual use, significant friction is generated between the outer ring and the self-aligning roller, and between the inner ring and the self-aligning roller during rotation. This friction intensifies wear with increasing usage frequency, leading to a higher wear rate of the self-aligning roller and consequently reducing the overall bearing life.
[0007] (II) Technical Solution
[0008] To achieve the above objectives, this utility model provides the following technical solution: a wear-resistant self-aligning roller bearing, comprising an outer ring and an inner ring, a cage installed between the outer ring and the inner ring, self-aligning rollers installed inside the cage, an auxiliary lubrication structure provided inside the outer ring, and an auxiliary protection structure provided on one side of the outer ring. The auxiliary lubrication structure includes an annular groove, an annular oil frame engaged with the inner wall of the annular groove, an oil inlet hole provided on one side of the annular oil frame, and a sealing block engaged with one side of the oil inlet hole. The auxiliary protection structure includes an internally threaded ring plate, one side of which is fixedly connected to one side of the outer ring.
[0009] As a further embodiment of this utility model: a threaded rod is fixedly connected to one side of the annular oil frame, and a fixing nut is threaded to one end of the threaded rod.
[0010] As a further embodiment of this utility model: a circular insertion hole is provided on the inner wall of the outer ring body, and the threaded insertion rod is inserted into the inner wall of the circular insertion hole.

[0012] As a further embodiment of this utility model: a rotating rod is rotatably connected to the inner wall of the oil outlet circular frame, and a rotating ball is fixedly connected to the outer surface of the rotating rod, with an oil collection groove opened at the bottom of the rotating ball.
[0013] As a further embodiment of this utility model: the inner wall of the internal threaded ring plate is threadedly connected to an external threaded ring plate, and an annular baffle is fixedly connected to one side of the external threaded ring plate.
[0014] As a further embodiment of this utility model: an annular guard plate is fixedly connected to the bottom of the annular baffle, and a rectangular protrusion is fixedly connected to the inner ring of the annular guard plate.
[0015] (III) Beneficial Effects
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0017] 1. This wear-resistant self-aligning roller bearing, through the setting of an auxiliary lubrication structure, can assist in the storage of lubricating oil under the action of the annular oil frame. Then, when the self-aligning roller rotates to the oil outlet ring (the length of the oil outlet ring is the same as the thickness of the auxiliary groove, so the oil outlet ring will not affect the rotation of the self-aligning roller), it can drive the rotating ball to rotate, so that the oil groove can take out the internal lubricating oil and apply it to the outer surface of the self-aligning roller, thereby lubricating the self-aligning roller with the outer ring and the inner ring, reducing friction.
[0018] 2. This wear-resistant self-aligning roller bearing features a threaded insert and a round insertion hole, allowing the threaded insert to be inserted into the round insertion hole. This, combined with the annular groove and fixing nut, facilitates the disassembly and assembly of the annular oil frame for easy replacement and maintenance.
[0019] 3. This wear-resistant self-aligning roller bearing, through the setting of an auxiliary protection structure, can connect the annular baffle and the outer ring body under the action of the internal threaded ring plate and the external threaded ring plate, and can then work with the annular guard plate to protect the threaded rod and the fixing nut and other parts.

A sealing block 58 is attached to one side of the oil inlet hole 57. The oil inlet hole 57 can inject oil into the inner wall of the annular oil frame 54. The sealing block 58 can lock the oil inlet hole 57. The auxiliary protection structure 6 includes an internal threaded ring plate 61. One side of the internal threaded ring plate 61 is fixedly connected to one side of the outer ring body 1. The internal threaded ring plate 61 can be fixed in conjunction with the external threaded ring plate 62.
[0029] Specifically, such as Figures 2-5As shown, a threaded rod 55 is fixedly connected to one side of the annular oil frame 54. A fixing nut 56 is threaded to one end of the threaded rod 55. A circular insertion hole 53 is provided on the inner wall of the outer ring body 1. The threaded rod 55 can be inserted into the inner wall of the circular insertion hole 53, thereby fixing it with the fixing nut 56 and allowing the annular oil frame 54 to be assembled and disassembled. Several oil outlet circular frames 59 are fixedly connected to the inner wall of the annular oil frame 54. The oil outlet circular frames 59 can assist in the discharge of lubricating oil inside the annular oil frame 54. 9 is connected to the interior of the annular oil frame 54. An auxiliary groove 52 is provided on the inner wall of the outer ring body 1. The oil outlet round frame 59 can be installed through the auxiliary groove 52. A rotating rod 510 is rotatably connected to the inner wall of the oil outlet round frame 59. The self-aligning roller body 3 can drive the rotating rod 510 to rotate, which in turn can drive the rotating ball 511 to rotate. The rotating ball 511 is fixedly connected to the outer surface of the rotating rod 510. An oil taking groove 512 is provided at the bottom of the rotating ball 511. The oil taking groove 512 can take out the lubricating oil inside the oil outlet round frame 59 during the rotation of the rotating ball 511.
[0030] Specifically, such as Figure 5 and Figure 6 As shown, the inner wall of the internal threaded ring plate 61 is threadedly connected to an external threaded ring plate 62.

The annular guard plate 64 can cooperate with the annular baffle 63 and other components to protect the threaded rod 55 and the fixing nut 56.
[0031] The working principle of this utility model is as follows:
[0032] S1. In use, the self-aligning roller body 3 is installed with the cage 2, and the cage 2 is installed with the outer ring body 1 and the inner ring body 4, so that the self-aligning roller body 3 can be installed with the outer ring body 1 and the inner ring body 4.
[0033] S2. At this time, the annular oil frame 54 is inserted into the inner wall of the annular groove 51, and the threaded rod 55 is inserted into the round insertion hole 53. Then, the fixing nut 56 is fixed to the threaded rod 55, and the lubricating oil is injected into the oil inlet hole 57. When the self-aligning roller body 3 rotates to the rotating ball 511, the oil extraction groove 512 can be driven to take out the lubricating oil inside.
[0034] S3. Fix the internal threaded ring plate 61 and the external threaded ring plate 62, which can then work with the annular guard plate 64 to protect the fixing nut 56 and the threaded rod 55, etc. The rectangular protrusion 65 can play an anti-slip role when rotating the annular baffle 63.
