Description

Deep groove ball bearing with large bearing capacity Technical Field The utility model relates to the technical field of deep groove ball bearings, in particular to a deep groove ball bearing with high bearing capacity. Background The deep groove ball bearing is a rolling bearing with the most widely used characteristics of small friction resistance and high rotating speed, and can be used for a machine part bearing radial load or combined load of radial and axial actions, and also can be used for a machine part bearing axial load, such as a small-power motor, a gearbox of an automobile and a tractor, a gearbox of a machine tool, a general machine, a tool and the like. A conventional deep groove ball bearing generally includes an outer ring, an inner ring, a plurality of balls, and a cage for spacing and guiding the plurality of rollers, wherein a raceway is formed by recesses of the outer ring and the inner ring, and the balls slide in the raceway to form a bearing structure capable of providing radial and axial rotational support. For example, a deep groove ball bearing of prior art publication No. CN220581496U, the utility model includes a body module including an inner ring, an outer ring disposed outside the inner ring, and steel balls disposed in an annular array between the inner ring and the outer ring. However, the prior art has the problem that the bearing capacity of the whole deep groove ball bearing is low due to the fact that the inner ring and the outer ring are supported by the plurality of balls, and stability in use is affected.
