Description

Technical Field

[0001] This utility model relates to the technical field of bearing retainers with self-lubricating structures, specifically a bearing retainer with a self-lubricating structure. Background Technology

[0002] Spherical plain bearings are a type of spherical sliding bearing. They can withstand large loads and, depending on their type and structure, can withstand radial loads, axial loads, or combined radial and axial loads. However, the bearing cage of a spherical plain bearing is not easy to self-lubricate, and insufficient lubrication can lead to wear of the bearing cage, thus affecting its service life, stable operation, and significantly reducing its wear resistance. Furthermore, it is not easy to prevent the lubricating oil from leaking onto the surface of the bearing cage, making it difficult to add lubricating media.

[0003] In existing technology, such as the patent announcement number CN218598639U, this utility model discloses a self-lubricating spherical plain bearing roller cage body, belonging to the field of bearing technology. It includes a spherical plain bearing roller cage body, with barrier sealing rings provided on both the upper and lower sides. The upper barrier sealing ring is threaded into several threaded grooves by several mounting bolts. This self-lubricating spherical plain bearing roller cage body, through the provision of barrier sealing rings, oil reservoirs, oil storage cotton, a flow outlet, mounting bolts, and threaded grooves, enables the device to automatically lubricate the bearing roller cage body, ensuring the stable operation of the spherical plain bearing. It also prevents wear of the spherical plain bearing roller cage body due to insufficient lubrication, thus affecting its service life, significantly improving the wear resistance of the spherical plain bearing. Furthermore, the two barrier sealing rings can block lubricating oil from the surface of the spherical plain bearing roller cage body, preventing oil leakage and facilitating the addition of lubricating media.

[0004] The aforementioned patent uses oil-absorbing cotton, but the lubricating oil is not easily discharged after absorption, and the oil-absorbing cotton is prone to corrosion and damage. The lubrication mechanism is complex, and the lubricating oil is easy to leak out after being added, resulting in poor sealing. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a bearing retainer with a self-lubricating structure to solve the problems of complex lubrication mechanisms and poor sealing caused by easy leakage of lubricating oil after it has been added.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a bearing retainer with a self-lubricating structure, comprising a bearing roller retainer body, a roller positioning groove formed on the inner surface of the bearing roller retainer body, a lubricating oil outlet channel formed on the inner surface of the roller positioning groove of the bearing roller retainer body, a lubricating oil storage cavity formed on the inner surface of the bearing roller retainer body, a support ring cover body fixedly connected to the upper surface of the bearing roller retainer body, the support ring cover body being fixedly connected to the upper surface of the bearing roller retainer body by screws, and an oil filling hole formed on the surface of the support ring cover body, the oil filling hole communicating with the lubricating oil storage cavity.

[0007] Preferably, the lubricating oil outlet channels are evenly distributed from top to bottom at the roller positioning groove of the bearing roller cage body, and the lubricating oil outlet channels adopt a small round hole structure.

[0008] Preferably, the lubricating oil outlet channel is interconnected with the lubricating oil storage cavity.

[0009] Preferably, the screw is a large-head flathead screw, and the upper end of the screw is pressed and fixed to the upper surface of the oil filling hole of the support ring cover body.

[0010] Preferably, the upper surface of the bearing roller cage body is provided with a threaded groove, and the screw is installed on the inner surface of the threaded groove by means of threads.

[0011] Preferably, the upper surface of the support ring cover body is provided with an insertion hole, and the outer surface of the screw slides through the inner surface of the insertion hole.

[0012] Preferably, the roller positioning grooves are evenly distributed on the surface of the bearing roller cage body, and the roller positioning grooves adopt an arc-shaped concave groove structure.

[0013] Compared with the prior art, this utility model provides a bearing retainer with a self-lubricating structure, which has the following beneficial effects:

[0014] By employing a circular cavity structure for storing lubricating oil between the roller positioning grooves of the bearing roller cage body, the oil filling hole is sealed by screws, so the oil will not be discharged from the oil filling port after filling. The sealing is strong and the lubrication mechanism is not easily damaged. The lubricating oil is discharged through multiple small lubricating oil discharge channels, making lubrication discharge convenient. Attached Figure Description
