Bearing convenient to disassemble and assemble

The bearing convenient to disassemble and assemble comprises an outer shaft sleeve and an inner shaft sleeve, the outer shaft sleeve and the inner shaft sleeve are rotationally connected through balls, five sets of evenly-distributed oil storage cavities are formed in the middles of the interiors of two sets of retainers, and push plates are installed in the oil storage cavities in a sliding mode. And reset springs are fixedly connected to the positions, close to the front side and the rear side, of the right end of the push plate, the other ends of the reset springs are fixedly connected with the inner right wall of the oil storage cavity, a through hole is formed in the middle of the inner left wall of the oil storage cavity, and an opening in the left end of the through hole communicates with the ball. Compared with a traditional bearing, the bearing is simpler and quicker to disassemble and assemble, the possibility that the outer shaft sleeve, the inner shaft sleeve and the balls are damaged is avoided,
