Double-row one-way bearing

A double-row one-way bearing comprising:

• a bearing outer ring and a bearing inner ring coaxially arranged around the central axis of the double-row one-way bearing, wherein the bearing outer ring and the bearing inner ring have raceways and the bearing inner ring is located inside the bearing outer ring;
• a plurality of spherical rollers arranged between the bearing outer ring and the bearing inner ring along the raceway;
• a plurality of wedges radially arranged between the bearing outer ring and the bearing inner ring relative to the central axis and spaced apart from the plurality of spherical rollers in the axial direction, and each wedge is provided with a groove at the side away from the bearing inner ring, a number of the plurality of wedges is greater than a number of the plurality of spherical rollers;
• a cage arranged coaxially with the bearing outer ring and the bearing inner ring and provided with a plurality of roller holding portions and a plurality of wedge holding portions, wherein the plurality of spherical rollers is respectively held in the plurality of roller holding portions and the plurality of wedges are respectively held in the plurality of wedge holding portions;
• an elastic limit ring coaxially arranged with the bearing outer ring and the bearing inner ring and passes through the groove of each wedge to apply a radially inward force to each wedge.
