[0002] Bearings are a kind of sliding parts commonly used in the machinery industry. With the continuous development of bearings, graphite bearings have been developed on the basis of metal bearings. Among them, graphite is resistant to high temperature, high strength, corrosion resistance, and light weight. Therefore, graphite bearings have become an important development direction of bearings.

[0003] After checking the publication (announcement) number: CN214404386U, a graphite bearing that is easy to disassemble is disclosed. This technology discloses "including a bearing seat, a rotating shaft arranged in the middle of the bearing seat, a mounting groove opened in the middle of the bearing seat and located on the circumference of the rotating shaft, a bearing arranged in the mounting groove and located on the circumference of the rotating shaft, and a sleeve arranged on the circumference of the bearing and in contact with the bearing. The bearing is composed of two detachable semi-cylinders, and the outer ends of the bearing and the sleeve are covered with a sealing gland. The end of the sleeve is provided with a spring groove, and the spring groove is located on the bottom surface of the mounting groove. A return spring is arranged in the spring groove. The sealing gland presses the bearing and the sleeve and makes the return spring abut against the bottom surface of the mounting groove. The graphite bearing has the advantages of simple structure and good strength."

[0004] However, the graphite bearing in the above-mentioned reference document is in a separated state after being disassembled from the rotating shaft. At this time, when the machine is disassembled for maintenance or the two half cylinders are carried and transported, the graphite bearing itself is not large in volume, and when it is separated into two half cylinders, the volume is even smaller, which makes it easier to cause the graphite bearing to be lost.

[0005] In order to solve the above problems, the present application proposes an easily disassembled graphite bearing. Utility Model Content
