[0020] When the conventional ball bearing of the utility model which is easy to disassemble and assemble is used, the assembly ring 8 is installed on the inner side of the inner ring 2 and the assembly ring 8 is fixed. The fixed assembly ring 8 forms a whole with the inner ring 2, and then the shaft rod to be installed and the assembly ring 8 can be installed; when disassembling the shaft rod, the first arc plates 17 of the two first spliced ring bodies 201 are rotated to the position of the disassembly groove 14, and then the connection between the first arc plate 17 and the second arc plate 18 is separated from the position of the disassembly groove 14. At this time, the first arc plate 17 can be disassembled, and synchronously, since the assembly ring 8 is connected to the first arc plate 17, the assembly ring 8 is disassembled synchronously. Then, the first arc plate 17 is separated from the assembly ring 8 first, and then the assembly ring 8 is separated from the shaft rod. After the first arc plate 17 is disassembled, a gap can be formed on the second raceway 7, and the ball can be conveniently disassembled by utilizing the gap. The overlapping edge 10 is connected to the first connection hole in the overlapping groove 9 by a first connection bolt 15, and the limiting block 11 is connected to the second connection hole in the limiting groove 12 by a second connection bolt 16. By arranging the overlapping edge 10 to cooperate with the overlapping groove 9, and arranging the limiting block 11 to cooperate with the limiting groove 12, the fixing stability of the assembly ring 8 can be improved.

[0021] The first arc plate 17 is provided with fixing grooves 19 at both ends, and the second arc plate 18 is provided with fixing blocks 20 at both ends.
