Problems solved by technology

[0006] The rotation speed of the two rows of steel balls is inconsistent, which produces a shear force on the one-piece cage, causing damage to the cage. In addition, due to the inconsistency of the speed, the cage is one-piece, which will inevitably lead to the steel balls with a slower speed. A certain amount of sliding will cause the friction, heat and peeling of the working surface; for this, some manufacturers design the cage as a split type, but this also has many defects. The structural space of the hub bearing is limited, and the distance between the two grooves is limited, which cannot accommodate the split type. Even if it is barely accommodated, its strength is very low, and it will break under a slight force; secondly, the split cage cannot effectively adjust the distance between the two rows of steel balls, and it is easy to cause the bearing to produce unbalanced load, resulting in Spalling of the working surface and eventual bearing failure

Embodiment

[0027] Such as figure 1 As shown, an angular contact ball bearing includes a flanged outer ring 1, two inner rings 2, two cages 3, several steel balls 4, a sealing ring 5, and a locking buckle 6. The inner ring 1 and the outer ring 2 form a double-row channel matching the steel ball 4, the cage 3 evenly distributes the steel ball 4 in the channel, and the sealing ring 5 is arranged between the outer ring and the inner ring Grooves are provided on the outside of the small end faces of the two inner rings 2, and the lock buckle 6 is arranged on the grooves of the two inner rings to fix the two inner rings. Grease is applied to the grooves of the inner and outer rings.

[0028] Such as Figure 2-3 As shown, the non-steel ball side of the cage is designed with several "V" grooves, which are consistent with the number of cage pockets and staggered with each other. After the bearing is assembled, the two cages are installed back to back, " The V"-shaped grooves cross each other, ...

Abstract

The invention relates to an angular contact ball bearing which comprises an inner ring, an outer ring, a sealing ring, a plurality of steel balls and a retainer; a double-row channel matching the steel balls is formed between the inner ring and the outer ring; the steel balls are uniformly distributed in the double-row channel by the retainer; the sealing ring is disposed at a edge side between the outer ring and the inner ring. Compared with the prior art, the ball bearing of the invention has the advantages of greatly improved bearing reliability and service life.

Description

technical field [0001] The invention relates to a bearing, in particular to an angular contact ball bearing. Background technique [0002] As a bearing for automotive hubs, its reliability directly affects personal safety, so the quality requirements for automotive hub bearings are very stringent. [0003] The main function of the automobile hub bearing is to bear weight and provide precise guidance for the rotation of the hub. It bears both axial load and radial load, as well as impact load. It is a very important component. Traditional automobile wheel bearings are used with two sets of tapered roller bearings or angular contact ball bearings. The installation, oiling, sealing and clearance adjustment of the bearings are all carried out on the automobile production line. This structure makes it difficult to assemble in the automobile production plant, high in cost, and poor in reliability. Moreover, when the automobile is maintained at the maintenance point, the bearing n...
