Abstract
The utility model discloses a hub bearing which comprises an outer ring component, an inner ring component and a roller bearing. The outer ring component comprises a first straight top surface and a first inclined bottom surface; and a distance between the first top surface and the first bottom surface is decreased gradually in a direction from a first end to a second end of the outer ring component. The inner ring component comprises a second straight top surface and a second inclined top surface; and a distance between the second top surface and the second bottom surface is increased gradually in a direction from a first end to a second end of the inner ring component, wherein the first bottom surface is parallel to the second top surface, and the first bottom surface and the second top surface form a bearing pedestal raceway together. The roller bearing is arranged in the bearing pedestal raceway. The outer ring component and the inner ring component of the hub bearing define the inclined bearing pedestal raceway together by using the incline surfaces, bulges and limited blocks; the precise location can be realized under a heavy load by using the cylindrical roller bearing with good stability and combing the inclined bearing pedestal raceway; and therefore, the hub bearing is suitable for being applied to a truck.
Description
Technical field
The utility model relates to auto parts and components, relate in particular to be used for truck can precision positioning hub bearing.
Background technique
The main effect of hub bearing is load-bearing and for the rotation of wheel hub provides accurate guiding, and it not only bears thrust load but also bear radial load, is very important component.Especially for the hub bearing of truck, because its load of bearing is bigger, so the bearing capacity of hub bearing and measure of precision seem more important.
Traditional hub bearing is combined by two cover tapered roller bearings or ball bearing.For example with reference to shown in Figure 1, Fig. 1 has disclosed a kind of example of traditional hub bearing, has wherein used ball bearing.This hub bearing comprises: outer coil assembly 101, inner ring assembly 102 and ball 103.Form bearing support after wherein outer coil assembly 101 and inner ring assembly 102 merge mutually, in bearing support, hold the structure that ball 103 forms ball bearing.
The hub bearing of this kind structure requires very high to assembly precision, in assembly process, be easy to generate bigger play between outer coil assembly 101 and the inner ring assembly 103, departing from appears in the bearing support that forms after causing merging, and makes ball 103 can't be positioned at the exact position of bearing support.When hub bearing bore bigger load, ball that departs from and bearing support were easy to damage, and cause whole hub bearing the situation of fatigue damage to occur, have a strong impact on working life.
The model utility content
The utility model is intended to propose a kind of hub bearing, can realize precision positioning and can carry bigger load, very is adapted at using on the truck.
According to an embodiment of the present utility model, a kind of hub bearing is proposed, comprise outer coil assembly, inner ring assembly and roller bearing.Outer coil assembly comprises first straight end face and first bottom surface of inclination, and first end of coil assembly is to the direction of second end outside this, and the distance between first end face and first bottom surface reduces gradually.Inner ring assembly comprises second straight bottom surface and second end face of inclination, from first end of this inner ring assembly direction to second end, distance between second end face and second bottom surface increases gradually, wherein this first bottom surface is parallel with second end face, and first bottom surface and second end face constitute the bearing support raceway jointly.Roller bearing is installed in the bearing support raceway.
In one embodiment, outer coil assembly comprises a projection, and this projection is positioned at first end of outer coil assembly.The projection and first bottom surface constitute the upper surface of bearing support raceway.
In one embodiment, inner ring assembly also comprises first limiting stopper and second limiting stopper.First limiting stopper is positioned at first end of inner ring assembly, and second limiting stopper is positioned at second end of inner ring assembly.Second end face between first limiting stopper and second limiting stopper constitutes the lower surface of bearing support raceway.
In one embodiment, roller bearing is the cylindrical roller bearing.
Face, projection and the limiting stopper that the outer coil assembly of hub bearing of the present utility model and inner ring assembly utilization are tilted defines the bearing support raceway of inclination jointly, the better columniform roller bearing of stability in use, can under heavier load, realize precision positioning in conjunction with the bearing support raceway that tilts, be suitable on truck, being applied.
Description of drawings
Fig. 1 has disclosed the structure of using traditional hub bearing of ball bearing.
Fig. 2 has disclosed the structural drawing according to an embodiment's of the present utility model hub bearing.
Embodiment
With reference to shown in Figure 2, the utility model proposes a kind of hub bearing 200, this hub bearing 200 comprises outer coil assembly 202, inner ring assembly 204 and roller bearing 206.
Roller bearing 206 is installed in the above-mentioned bearing support raceway.In one embodiment, for stability and the bearing capacity that improves roller bearing, use columniform roller bearing.With reference to shown in Figure 2, the true dip direction of bearing support raceway is the direction of drawing in towards the central position of hub bearing.So the roller bearing that is placed on wherein also is to draw in towards the central position, helps carrying greater weight load like this.
Face, projection and the limiting stopper that the outer coil assembly of hub bearing of the present utility model and inner ring assembly utilization are tilted defines the bearing support raceway of inclination jointly, the better columniform roller bearing of stability in use, can under heavier load, realize precision positioning in conjunction with the bearing support raceway that tilts, be suitable on truck, being applied.
