Description

Technical Field

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

[0002] Bearings play a crucial role in various mechanical transmission systems, and their performance directly affects the operational stability, service life, and efficiency of the entire mechanical device. Traditional bearings mostly involve direct contact friction during rotation, which easily leads to component wear, causing a rapid decline in bearing precision and a significantly reduced lifespan. As equipment operates for longer periods, the heat generated by friction accumulates, potentially further deteriorating the working environment, affecting the performance of surrounding components, and even causing the entire transmission system to malfunction and shut down due to localized overheating. Current bearing lubrication is achieved through lubricants, with lubricating oil being the most commonly used. However, its chemical properties are unstable, and it is prone to deterioration at high temperatures, thus requiring frequent replacement, which is time-consuming and labor-intensive.

[0003] Based on the above, this utility model proposes a self-lubricating bearing, which can effectively solve the above problems. Utility Model Content

[0004] This utility model addresses the shortcomings of the existing technology by providing a self-lubricating bearing. This utility model is achieved through the following technical solution:

[0005] A self-lubricating bearing includes a ball socket and a ball head. The ball socket has a spherical hole, and arc-shaped grooves are formed on both the upper and lower sides of the spherical hole. The ball head is embedded in the spherical hole, and the ball head has a shaft hole. An annular groove is formed on the surface of the shaft hole, and two lubricating films with a semi-circular cross-section are detachably connected inside the annular groove.

[0006] According to the above technical solution, as a further preferred technical solution, two connecting holes are formed inside the annular groove.

[0007] According to the above technical solution, as a further preferred technical solution, the outer surface of the lubricating film is provided with a plurality of spaced positioning blocks that are connected to and cooperate with the annular groove, and a connecting post that cooperates with and is connected to the connecting hole is fixedly connected to the outside of one of the positioning blocks.

[0008] According to the above technical solution, as a further preferred technical solution, the inner surface of the lubricating film is provided with a plurality of spaced sliding protrusions.

[0009] According to the above technical solution, as a further preferred technical solution, a limiting groove is opened on both sides of the ball head, a limiting baffle is installed in the limiting groove, and the limiting baffle is fixedly connected to the ball head by multiple bolts.

[0010] According to the above technical solution, as a further preferred technical solution, the material of the lubricating film is fluorinated graphite.

[0011] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0012] This utility model provides a self-lubricating bearing. By setting a spherical hole and an arc groove, the ball head can be pressed into the arc groove and rotated 90 degrees to install the ball head in the spherical hole of the ball socket, making installation and disassembly convenient. At the same time, by detachably connecting a lubricating film in the annular groove of the ball head, sliding friction is achieved when the ball head rotates with the connecting shaft, which increases the smoothness of rotation and extends the service life of the ball head.

[0017] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. However, it should be understood that the accompanying drawings are for illustrative purposes only and should not be construed as limiting this patent. For better illustration of this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions. It is understandable that some well-known structures and their descriptions may be omitted in the drawings for those skilled in the art. The positional relationships described in the drawings are for illustrative purposes only and should not be construed as limiting this patent.

[0018] A self-lubricating bearing includes a ball socket 1 and a ball head 2. The ball socket 1 has a spherical hole 11, and arc-shaped grooves 12 are formed on both the upper and lower sides of the spherical hole 11. The ball head 2 is embedded in the spherical hole 11, and the ball head 2 has a shaft hole 21. An annular groove 22 is formed on the surface of the shaft hole 21, and two lubricating films 3 with a semi-circular cross-section are detachably connected inside the annular groove 22.

[0019] This invention, by setting a spherical hole 11 and an arc-shaped groove 12, allows the ball head 2 to be pressed into the arc-shaped groove 12 and rotated 90 degrees, thus installing the ball head 2 in the spherical hole 11 of the ball socket 1, making installation and disassembly convenient. At the same time, by detachably connecting a lubricating film 3 in the annular groove 22 of the ball head 2, sliding friction is achieved when the ball head 2 rotates with the connecting shaft, increasing the smoothness of rotation and extending the service life of the ball head 2.

[0020] Furthermore, in another embodiment, two connecting holes 23 are formed inside the annular groove 22. The outer surface of the lubricating film 3 is provided with a plurality of spaced positioning blocks 31 that are connected to the annular groove 22, and a connecting post 32 that is connected to the connecting hole 23 is fixedly connected to the outside of one of the positioning blocks 31.

[0021] The cooperation between the annular groove 22 and the positioning block 31, as well as the connecting hole 23 and the connecting post 32, makes the lubricating film 3 easy to install and easy to disassemble and replace when the lubricating film 3 is worn.

[0022] Furthermore, in another embodiment, the inner surface of the lubricating film 3 is provided with a plurality of spaced sliding protrusions 33.

[0023] By setting the sliding protrusion 33, the contact area between the lubricating film 3 and the connecting shaft is reduced, thereby further reducing sliding friction.

[0024] Furthermore, in another embodiment, limit grooves 24 are respectively opened on both sides of the ball head 2, and limit baffles 4 are installed in the limit grooves 24. The limit baffles 4 are fixedly connected to the ball head 2 by multiple bolts 5.

[0025] By setting a limiting baffle 4, the lubricating film 3 is prevented from slipping out of the annular groove 22; at the same time, when it is necessary to replace the lubricating film 3, the limiting baffle 4 at either end of the ball head 2 can be removed to directly replace the film.

[0026] Furthermore, in another embodiment, the lubricating film 3 is made of fluorinated graphite.

[0027] By setting a lubricating film 3 made of fluorinated graphite, the bearing has good wear resistance and lubrication performance, long service life, and does not need to be replaced frequently; and the fluorinated graphite enables the bearing to operate at higher strength and temperature.
