The utility model relates to the field of bearings, and discloses a double-row series angular contact ball bearing, which comprises an outer ring (10) and an inner ring (11), two rows of rolling bodies (12) are arranged between the outer ring (10) and the inner ring (11), the outer ring (10) surrounds the outer side of the inner ring (11), at least two flanges (101) used for being connected with a supporting unit are arranged at the end part of the outer ring (10), all the flanges (101) are uniformly distributed on the outer ring (10), and the inner ring (11) is arranged on the outer ring (10). And the flange (101) is provided with a mounting hole (102) for a bolt to pass through. A flange is additionally arranged on the outer ring and connected with the end face of the supporting unit through a bolt, higher connecting strength can be provided, axial pre-tightening force can be generated, and therefore the rotating precision of the bearing is improved, the rigidity of the bearing device is improved, the number of rolling bodies borne in the bearing is increased, the rationality of load distribution in the bearing is improved, and the service life of the bearing is prolonged.

The present disclosure relates to the technical field of electromagnetic bearing, and particularly relates to an electromagnetic bearing rotor system, which comprises a rotating shaft and a mounting base, the mounting base is coaxially provided with an electromagnetic bearing assembly and an auxiliary bearing assembly, the rotating shaft is arranged through the electromagnetic bearing assembly and the auxiliary bearing assembly; the auxiliary bearing assembly comprises an outer ring valve seat, an inner ring valve seat and an auxiliary bearing, the outer ring valve seat is connected with an outer ring of the auxiliary bearing, and the inner ring valve seat is connected with an inner ring; a gap is formed between the outer ring valve seat and the mounting base along the axial direction of the rotating shaft, an elastic member is arranged in the gap, a connecting hole for the rotating shaft is arranged on the inner ring valve seat, an abutting surface is formed on the wall of the connecting hole, the abutting surface is inclinedly extended along the axial direction of the rotating shaft and away from the rotating shaft, the rotating shaft is abutted with the abutting surface, so that the axial and radial loads are balanced through the elastic member, the auxiliary bearing is protected, the supporting effect of the auxiliary bearing assembly on the rotating shaft is further improved, and the electromagnetic bearing assembly is better protected.
