[0002] The self-aligning rotor bearing has a double-row rotor, a common spherical raceway on the outer ring, and two raceways on the inner ring, which are tilted at an angle relative to the bearing axis. This ingenious structure enables it to have automatic self-aligning performance, so it is not easily affected by the angle error between the shaft and the bearing box seat or the shaft bending, and is suitable for occasions where the angle error is caused by installation error or shaft deflection. In addition to being able to withstand radial loads, the bearing can also withstand bidirectional axial loads.

[0003] A Chinese patent with publication number CN219176778U discloses a spherical roller bearing, which includes an inner ring, a double-row roller fitting movably sleeved on the side wall of the inner ring, an outer ring movably sleeved on the side wall of the double-row roller fitting, a sealing ring assembly is provided on the front and back of the double-row roller fitting, an outer fixed ring assembly is provided on the front and back of the outer ring, an inner fixed ring assembly is provided on the front and back of the inner ring, the outer fixed ring assembly has the same structure as the inner fixed ring assembly, the outer fixed ring assembly includes a large ring member, a small ring member is fixedly connected to the back of the large ring member, and a plurality of plugs are fixedly connected to the back of the small ring member. The utility model is a spherical roller bearing, which changes the installation method of the sealing ring assembly from the traditional installation method of inserting the sealing ring assembly into the gap between the inner ring and the outer ring to the method of fixing the sealing ring assembly by cooperating with the outer fixed ring assembly and the inner fixed ring assembly, so that the installation of the sealing ring assembly is more convenient and labor-saving.
