Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0026] The present utility model provides a Figures 1 to 6 double-row single-column tapered roller combined bearing as shown, including a first outer ring section 1 and a second outer ring section 4. The first outer ring section 1 and the second outer ring section 4 form an outer ring body, and the outer ring body is in a circular ring shape. The outer ring body is set to be composed of the first outer ring section 1 and the second outer ring section 4, which is convenient for disassembly and repair in case of damage, thus avoiding overall replacement.

[0027] To realize the connection between the first outer ring section 1 and the second outer ring section 4, T-shaped blocks 6 are integrally formed at both ends of the second outer ring section 4. T-shaped grooves 5 are provided on the first outer ring section 1 for plugging and matching with the T-shaped blocks 6. An inner ring body 2 is arranged inside the outer ring body. Bolts 7 are provided at the T-shaped grooves 5, and the T-shaped blocks 6 and the first outer ring section 1 are fastened by the bolts 7. Specifically, the T-shaped blocks 6 are plugged into the corresponding T-shaped grooves 5, and then fastened by the bolts 7 to improve the connection stability between the first outer ring section 1 and the second outer ring section 4. At the same time, when disassembling, the bolts 7 are removed, and the outer ring body is disassembled into the first outer ring section 1 and the second outer ring section 4, which is convenient for maintenance.

[0028] End caps 3 are rotatably arranged between the outer ring body and the inner ring body 2. The end caps 3 are rotatably connected between the outer ring body and the inner ring body 2. Two end caps 3 are provided, and the two end caps 3 are respectively located on both sides of the inner ring body 2. A dynamic seal ring (shown in the figure) is provided at the edge of the end cap 3. The dynamic seal ring is slidably connected to the outer side of the inner ring body 2 and the inner side of the outer ring body 2 through the two end caps 3 respectively to prevent impurities from falling into the interior and causing damage.
