Bearings are usually composed of an outer ring, an inner ring, a cage, rolling elements, etc. During use, bearings need to be lubricated regularly to reduce bearing wear.

[0003] For example, CN215567303U discloses a spherical bearing with an auxiliary lubrication structure, including a bearing ring body. The bearing ring body is installed in a bearing and rotating structure, with a middle portion protruding outward and an outer wall having an arc-shaped cross-section. A group of lubricating bumps are embedded in the bearing ring body, and the lubricating bumps are arranged in sequence along the circumference of the bearing ring body. The bearing and rotating structure are lubricated by the lubricating bumps. A group of lubrication grooves are also provided in the bearing ring body, and the lubrication grooves are arranged in sequence along the circumference of the bearing ring body. The lubrication grooves are recessed into the interior of the bearing ring body, and grease can be accommodated in the lubrication grooves. The spherical bearing has lubricating bumps embedded in the bearing ring body, and the bearing and rotating structure is lubricated by the lubricating bumps. At the same time, a lubrication groove is provided on the bearing ring body, and the depth of the middle portion of the lubrication groove is greater than the depth at both ends thereof. The grease is stored in the middle portion of the lubrication groove, and can seep out from both ends of the lubrication groove to enter between the outer wall of the bearing ring body and the bearing and rotating structure, playing an auxiliary lubrication role, thereby improving the lubrication performance of the bearing.

The installation is difficult and time-consuming, which affects the installation efficiency of the bearing. Utility Model Content
