Embodiment Construction

[0037] It can be seen from the background technology that the current hub bearing unit has the problem of interference between the stop ring and the axle tube.

[0038] Please refer to Figure 1-Figure 3 , figure 1 is a structural schematic diagram of a stop ring; figure 2 is a sectional view of a hub bearing unit; image 3 yes figure 2 Partial enlarged schematic diagram of region A in middle.

[0039] As shown in the figure, a hub bearing unit includes: a first bearing 5 , a second bearing 6 , a stop ring 4 and a hub 7 .

[0040] When assembling, the outer rings of the first bearing 5 and the second bearing 6 are pressed into the hub successively, and then the inner ring support tool of the first bearing 5 is installed on the workbench, and the inner components of the first bearing (inner ring, roller and cage) on the tooling, and then insert the hub 7 that has been press-fitted with the outer ring, then put the second bearing inner assembly, and finally place the stop...

Abstract

The invention discloses a hub bearing unit and a stop ring. The stop ring comprises a connecting portion, a first supporting portion and a second supporting portion, the connecting portion is integrally of a closed annular structure, the first supporting portion is integrally of an annular structure and is fixedly connected with the axial first end of the connecting portion, the diameter of the outer ring surface of the first supporting portion is larger than that of the outer ring surface of the connecting portion, the second supporting portion is integrally of an annular structure and is fixedly connected with the axial second end of the connecting portion, and the diameter of the outer ring surface of the second supporting portion is larger than that of the outer ring surface of the connecting portion. According to the stop ring provided by the embodiment, the deformation resistance is relatively high, change, cause by assembly, of the inner diameter size of the stop ring can be avoided, so that it is ensured that under the situation that the stop ring is matched with a hub bearing, the change, caused by assembly, of the inner diameter of the stop ring can be avoided, then the assembled stop ring protrudes out of the inner diameter portion of the hub bearing, and interference on shaft pipe installation is avoided.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of machinery, and in particular to a hub bearing unit and a stop ring. Background technique [0002] The main function of the hub bearing is to bear weight and provide precise guidance for the rotation of the hub. It bears both axial load and radial load, and is a very important component. The hub bearing unit is developed on the basis of standard angular contact ball bearings and tapered roller bearings. It combines two sets of bearings into one, with good assembly performance, clearance adjustment can be omitted, light weight, compact structure, and high load capacity. Large and other advantages, has been widely used in trucks. [0003] The hub bearing unit includes a hub, a first bearing, a second bearing and a stop ring, the first bearing and the second bearing are assembled into one body through the stop ring, and the stop ring is used to limit the shaft of the first bearing a...
