Deep groove ball bearing capable of achieving expected damping effect

A deep groove ball bearing capable of realizing an expected damping effect belongs to the technical field of bearings and comprises an outer ring, an inner ring, a steel ball, two half retainers, rivets and sealing rings arranged at two ends of an inner hole of the bearing, the inner ring is sleeved in the outer ring, the outer wall of the inner ring is provided with an inner ring raceway, the inner wall of the outer ring is provided with an outer ring channel, and a steel ball is arranged between the outer ring channel and the inner ring raceway; the steel ball is in interference fit with the outer ring channel, the steel ball and the outer ring channel are mutually extruded and occluded to form an occluded layer A, meanwhile, the steel ball is in interference fit with the inner ring raceway, and the steel ball and the inner ring raceway are mutually extruded and occluded to form an occluded layer B; the meshing interference magnitudes (delta) of the meshing layer A and the meshing layer B are the same, and
