Abstract
The utility model discloses an automobile wheel hub bearing unit which belongs to an automobile component device. The traditional automobile wheel hub bearing unit has the defects that an inner ring is easy to generate dislocation deformation and gaps, and the installation is relatively complicated. The utility model has the technical scheme that a roll way is formed on the outer surface of a bearing installing shaft to be used as the roll way of one row of rollers of double rows of angle contact ball bearings; an inner ring provided with a roll way of the other row of rollers is sheathed on the outer surface of the bearing installing shaft; and one inner ring is omitted. During the installation, the position of only one inner ring is limited in an axial direction, so the installation is relatively simple, deformation caused by dislocation is avoided, and the axial movement is difficult to occur after the installation and position limitation.
Description
Technical field
The utility model belongs to the auto parts and components field, and is especially relevant with a kind of automobile-used hub-bearing unit.
Background technique
A kind of automobile hub bearing as shown in Figure 1, comprise bearing support and double-row angular contact bal bearing, bearing support is made up of flange plate 1 that is connected as a single entity and tubular Bearing Installation axle 2, Bearing Installation axle 2 outer surfaces are provided with end face by shoulder near flange plate 1 one sides, double-row angular contact bal bearing comprises integral type outer race 3 and inner ring 4 and 5, inner ring 4 and 5 is set in Bearing Installation axle 2 outer surfaces, inner ring 4 is resisted against described end face by shoulder, the axial flanging of Bearing Installation is pressed against inner ring 5, and inner ring 4 and 5 is carried out axial limiting.Because inner ring is a separated type, two inner rings have concentricity requirement, install relatively numerous and diverse, also be easy to generate dislocation deformation effect precision during installation, after using after a while, be easy to generate the gap between two inner rings, inner ring will produce and move axially, cause bearing noise to become big, also can influence precision and life-span simultaneously.
The model utility content
The purpose of this utility model overcomes the inner ring that above-mentioned automobile hub bearing exists and is easy to generate dislocation distortion and gap and relatively numerous and diverse defective is installed, and provides the simple relatively and inner ring of a kind of installation can not produce axially movable automobile-used hub-bearing unit.For this reason, the utility model is by the following technical solutions:
Automobile-used hub-bearing unit, comprise bearing support and double-row angular contact bal bearing, bearing support is made up of flange plate that is connected as a single entity and tubular Bearing Installation axle, it is characterized in that: described Bearing Installation axle outer surface diameter is provided with raceway from forming end face by shoulder near flange plate one side direction away from stepped the diminishing of flange plate one side near flange plate one side bearing installation shaft outer surface; Described double-row angular contact bal bearing comprises integral type outer race, inner ring and two row rollers and dust-proof seal ring, described inner ring is set in described Bearing Installation axle outer surface and one end-face is resisted against described end face by shoulder, the outer volume of Bearing Installation shaft end is pressed against the other end end face of this inner ring, and inner ring is carried out axial limiting; Wherein a row roller is installed on the raceway on the described Bearing Installation axle outer surface, is inner ring with the Bearing Installation axle, and another row roller is installed on described inner ring.
As to technique scheme replenish and perfect, the utility model also comprises following technical characteristics:
Described double-row angular contact bal bearing both sides are respectively arranged with dust-proof seal ring, play dustproof and seal action.
Use the utility model can reach following beneficial effect: to use the raceway that is arranged on Bearing Installation axle outer surface as the double-row angular contact bal bearing raceway of a row roller wherein, reduced by an inner ring, make installation relatively simple; As long as an inner ring is carried out axial limiting, avoid the dislocation distortion during installation, and installed to be not easy to produce after spacing and move axially, improved the precision and the working life of bearing unit, reduced bearing noise.
