[0002] Round-hole agricultural machinery bearings are a type of bearing used in agricultural machinery and equipment. They are characterized by a circular hole inside the bearing for mounting on the shaft of agricultural machinery and equipment. This type of bearing is usually composed of an inner ring, an outer ring, rolling elements, and a cage. The inner ring is the inner annular part of the bearing, which is usually circular and fits tightly with the shaft so that the shaft can rotate in it. The outer ring is the outer annular part of the bearing, which is also usually circular and fits with the bearing seat or housing so that the bearing can be firmly mounted on the agricultural machinery and equipment. The rolling elements are rolling elements inside the bearing, usually steel balls, rollers, or needle shafts, which can roll between the inner and outer rings, reduce friction, and allow the bearing to rotate smoothly. The cage is used to maintain the position of the rolling elements so that they are evenly distributed between the inner and outer rings to prevent the rolling elements from colliding with each other. The round-hole agricultural machinery bearing assembly fixture is a tool used to assist in the assembly of round-hole agricultural machinery bearings. When the round-hole agricultural machinery bearing assembly fixture is used, it is not convenient to keep the inner ring centered when assembling the outer and inner rings, and it is not convenient during assembly.
