Description

Technical Field

[0001] This utility model relates to the field of bearing technology, specifically to a self-lubricating bearing structure. Background Technology

[0002] Bearings are typically fitted onto the outside of a rotating shaft and embedded within a bearing housing, allowing the bearing housing to support the rotating shaft while reducing the friction generated during its rotation.

[0003] Patent CN218625103U discloses an embedded bearing self-lubricating structure, including: a bearing housing, a bearing body installed in the inner cavity of the bearing housing, the bearing body including an outer ring and an inner ring, an oil injection groove is provided on the outer side wall of the outer ring, and a through hole is provided at the bottom of the oil injection groove; a protrusion is provided on the inner side wall of the annular sponge, the protrusion penetrates the inner cavity of the through hole and extends to the space between the outer ring and the inner ring.

[0004] To address the problem of poor lubrication caused by the outer ring of a bearing being fixedly embedded in the bearing housing, making it difficult to evenly distribute lubricating oil onto the rolling element surface, existing technology involves guiding lubricating oil through a protrusion between the outer and inner rings. The centrifugal force generated by the rotation of the cage then evenly distributes the lubricating oil to the surface of each ball, thus improving lubrication. However, this method requires stopping the bearing and removing external lubricating oil, applying it to the area requiring lubrication while the bearing is rotating. This is cumbersome and time-consuming. Utility Model Content

[0005] The purpose of this invention is to provide a self-lubricating bearing structure to solve the problems mentioned in the background art.

[0008] By adopting the above technical solution, the connection between the slide groove, the second through groove and the discharge groove facilitates the flow of lubricating oil in the first through groove to the discharge groove through the second through groove, so as to discharge the lubricating fluid in the second through groove and prevent the accumulation of lubricating fluid from affecting the bearing body.

[0009] A further improvement of the present invention is that the bearing assembly includes a bearing body rotatably connected inside the outer ring, and a collar is fixedly connected to the outer surface of the bearing body.

[0010] A further improvement of this utility model is that the collar is rotatably connected to the ring groove, and the outer wall of the collar is in contact with the inner wall of the ring groove.

[0011] By adopting the above technical solution, the bearing body is limited by the collar to prevent the bearing body from detaching from the inner part of the outer ring. The contact between the collar and the ring groove allows the collar to directly contact the lubricant inside the ring groove, so that the lubricant can act on the bearing body.

[0022] The present invention will be further described in detail below with reference to embodiments: Example 1 like Figure 1-5 As shown, this utility model provides a self-lubricating bearing structure, including a base 1, a limiting component 2 is provided at the upper end of the base 1, a bearing component 3 is provided inside the limiting component 2, and an adjusting component 4 is provided on the outer side of the limiting component 2. The limiting component 2 includes a support plate 21 fixedly connected to the outer side of the upper end of the base 1. A conveying pipe 22 is fixedly connected to the inner side of the support plate 21. An outer ring 23 is fixedly connected to the center of the upper end of the base 1. An annular groove 24 is formed on the inner wall of the outer ring 23. A first through groove 25 is formed through the inner side wall of the annular groove 24. A second through groove 26 is formed through the bottom of the annular groove 24. A sliding groove 27 is formed on the outer side of the bottom of the annular groove 24. A baffle 28 is fixedly connected to the inner side of the outer side of the sliding groove 27. A circular groove 281 is formed through the outer side of the baffle 28. A discharge groove 29 is formed through the center of the upper end of the base 1. The chute 27 is connected to the second through groove 26, the discharge chute 29 is in close contact with the second through groove 26, the first through groove 25 is connected to the conveying pipe 22, and the conveying pipe 22 is externally connected to lubricating oil.

[0023] In this embodiment, the connection between the slide groove 27, the second through groove 26 and the discharge groove 29 facilitates the flow of lubricating oil in the first through groove 25 down to the discharge groove 29 through the second through groove 26, so as to discharge the lubricating fluid in the second through groove 26 and prevent the accumulation of lubricating fluid from affecting the bearing body 31.

[0024] Example 2 like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, the bearing assembly 3 includes a bearing body 31 rotatably connected inside the outer ring 23, and a collar 32 is fixedly connected to the outer surface of the bearing body 31. The collar 32 is rotatably connected to the annular groove 24, and the outer wall of the collar 32 is in contact with the inner wall of the annular groove 24.

[0025] In this embodiment, the bearing body 31 is limited by the collar 32 to prevent the bearing body 31 from detaching from the inner part of the outer ring 23. The contact between the collar 32 and the ring groove 24 allows the collar 32 to directly contact the lubricant inside the ring groove 24 so that the lubricant can act on the bearing body 31.

[0026] Example 3 like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the adjustment component 4 includes a base plate 41 slidably connected to the inner wall of the slide groove 27, a long rod 42 and a spring 43 are fixedly connected to one side of the base plate 41, an auxiliary plate 44 is fixedly connected to the outer end of the long rod 42, and a pull rod 45 is fixedly connected to the outer side of the long rod 42. The long rod 42 passes through the interior of the circular groove 281, the auxiliary plate 44 is located on the outside of the baffle 28, the spring 43 is located around the long rod 42, and the outer end of the spring 43 is fixedly connected to the inner wall of the baffle 28.

[0027] In this embodiment, the base plate 41 covers the second through groove 26 to prevent the lubricant inside the annular groove 24 from leaking out through the second through groove 26. The presence of the long rod 42 facilitates the horizontal sliding of the base plate 41 along the slide groove 27. The auxiliary plate 44 connects the two sets of long rods 42 into a whole so that the two sides of the base plate 41 can be shifted synchronously. The spring 43 pushes the base plate 41 to move inward along the slide groove 27 so that the base plate 41 always forms a blocking cover on the second through groove 26 without being subjected to external force.

[0028] The working principle of this self-lubricating bearing will be explained in detail below.

[0029] like Figure 1-5 As shown, when the bearing body 31 needs to be lubricated, lubricant is injected into the first through groove 25 through the delivery pipe 22, so that the lubricant can pass through the first through groove 25 and enter the ring groove 24. Under the action of the continuous rotation of the bearing body 31, the collar 32 will drive the lubricant in the ring groove 24 to rotate continuously, so that the lubricant can form a complete coverage of the collar 32 and the bearing body 31, that is, the bearing body 31 is effectively lubricated. After the bearing body 31 is lubricated, when the lubricant accumulated inside the annular groove 24 needs to be drained, the operator can pull the pull rod 45 outward, which will drive the base plate 41 to move outward inside the slide groove 27 via the auxiliary plate 44 and the long rod 42, and compress the spring 43. As the base plate 41 moves outward, the cover formed by the base plate 41 on the second through groove 26 disappears. At this time, the discharge chute 29 in the closed state can be placed in the open state. Since the second through groove 26 is located at the bottom of the outer ring 23, the lubricant will flow to the second through groove 26. Then the lubricant flows to the outside through the discharge chute 29, thereby draining the lubricant accumulated inside the annular groove 24.

[0030] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
