[0026] As Figures 1-4 shown, the present utility model provides a technical solution: an angular contact ball bearing that is convenient for disassembly and assembly, including an outer ring 1 of the bearing and an inner ring 2 of the bearing. A cage 3 is arranged between the outer ring 1 of the bearing and the inner ring 2 of the bearing. Rolling balls 4 are installed on the inner wall of the cage 3. By setting the rolling balls 4, the cage 3, the outer ring 1 of the bearing and the inner ring 2 of the bearing, a complete bearing can be assembled. On one side of the outer surface of the outer ring 1 of the bearing, there is a disassembly, installation and cleaning structure 5. On one side of the outer surface of the inner ring 2 of the bearing, there is a disassembly, installation and fixing structure 6. The disassembly, installation and cleaning structure 5 includes an annular plate 51. One side of the outer surface of the annular plate 51 is fixedly connected to one side of the outer surface of the outer ring 1 of the bearing. An annular clamping frame 52 is fixedly connected to one side of the outer surface of the annular plate 51. By setting the annular plate 51 and the annular clamping frame 52, the annular clamping block 53 can be assisted in disassembly and assembly.
[0027] Specifically, as Figure 2 and Figure 3As shown in the figure, an annular clamping block 53 is clamped on the inner wall of the annular clamping frame 52. A circular insertion hole 54 is opened on one inner wall of the annular clamping frame 52. By setting the annular clamping frame 52, it can cooperate with the annular clamping block 53 for auxiliary fixation. A threaded clamping rod 56 is inserted into the inner wall of the circular insertion hole 54. A threaded clamping hole 55 is opened on the inner wall of the annular clamping block 53. The threaded clamping rod 56 and the threaded clamping hole 55 are detachably threadedly connected. By setting the threaded clamping rod 56 and the threaded clamping hole 55, it can assist in the disassembly and assembly of the annular clamping frame 52 and the annular clamping block 53. One side of the outer surface of the annular clamping block 53 is fixedly connected with a protective frame 57. The protective frame 57 is in a funnel shape. By setting the protective frame 57, it can cooperate with the annular clamping frame 52 and the annular clamping block 53 for disassembly and assembly. One side of the outer surface of the protective frame 57 is fixedly connected with an annular frame 58. An annular brush frame 59 is fixedly connected to the inner wall of the annular frame 58. By setting the annular brush frame 59, it can cooperate with components such as the annular frame 58 for auxiliary cleaning.
[0028] Specifically, as Figure 4 shown, the disassembly and assembly fixing structure 6 includes a limiting frame 61.
