As a further description of the above technical solution:

the retainer ring and the mandrel are manufactured integrally.

As a further description of the above technical solution:

one end, far away from the second bearing outer ring, of the first bearing outer ring is attached to the inner side of the retainer ring, and one end, far away from the first bearing outer ring, of the second bearing outer ring is attached to the inner side of the spacer ring.

As a further description of the above technical solution:

the heights of the first roller pin and the second roller pin are the same as those of the first bearing outer ring and the second bearing outer ring.

Current double row cylindrical roller gyro wheel outer lane is integral double raceway, and is unanimous at the straight occasion rotation rate, nevertheless needs the circumference rotation's occasion like dividing table, and is different because of the radius of rotation is different to lead to rotation rate, the utility model discloses a low outer height in two outer lanes can make 2 rows of rollers and 2 outer lane rotation rates has improved the rotatory flexibility of gyro wheel, and it is spacing to adopt step axle and retaining ring to carry out the axial simultaneously.

The utility model discloses following beneficial effect has:

1. the utility model discloses in be provided with the duplex bearing outer lane, and two bearing inner circles the inner all is provided with the kingpin, and seamless laminating between two bearing inner circles, the design of this structure makes the bulk strength of this bearing higher, has fabulous impact resistance, and life is longer, has improved the rotatory flexibility of gyro wheel.

2. The utility model discloses well bearing inner race direct and dabber outer wall contact do not need design bearing inner race, and the sealing washer is not designed to both sides simultaneously, utilizes the space ring to realize that the bearing is sealed, makes whole bearing structure simpler.

3. The utility model discloses well roller bearing of design simple structure, the installation of being convenient for.
