[0002] Spherical bearings are a type of spherical sliding bearings whose sliding contact surfaces are an inner spherical surface and an outer spherical surface. They can rotate and swing at any angle during movement, and can withstand large loads.

[0003] There are existing bearings with internal lubrication components, such as a new type of spherical concentric spherical bearing disclosed in Chinese patent application CN217761716U, which records: it includes a bearing outer ring, a bearing inner ring and a lubrication component, the bearing inner ring is arranged on the inner side of the bearing outer ring, the lubrication component includes a discharge component and an injection component, the discharge component is arranged inside the bearing outer ring, and the injection component is detachably connected to the outer side of the bearing outer ring.

[0004] During the use of the above-mentioned bearings with internal lubrication components, workers are required to regularly use a filling funnel to add lubricant. A large amount of lubricant is added to the bearing, which causes the lubricant to leak from the side of the bearing, affecting the lubrication and performance of the bearing, and easily causing bearing damage. The bearing is not easy to disassemble, and the inspection and cleaning of the internal ball of the bearing is more difficult. Utility Model Content

[0012] As a preferred solution of the bearing with internal lubrication assembly described in the utility model, a sliding block is fixedly connected to the lower surface of the buckle block, and the sliding block is slidably connected to the sliding track.

[0013] As a preferred solution of the bearing with internal lubrication assembly described in the utility model, one end of the buckle block is slidably connected to the clamping cavity, and the clamping cavity is opened on the upper surface of the outer ring of the lower bearing.

[0014] Compared with the known prior art, the technical solution provided by the utility model has the following beneficial effects:

The disassembly and installation process is simpler, which can reduce the cost and time of mechanical maintenance, thereby reducing the overall operating cost and improving maintenance efficiency.
