Abstract
The utility model discloses a bearing support of a rear end cover for an automobile motor, belonging to a machine element, and aims to provide a bearing support which contributes to reducing the motor volume and the cost and has a simple structure. The bearing support comprises a bearing support body; a ring-shaped groove (2) is arranged on the surface of a bearing hole where the bearing support body (1) is matched with a bearing outer ring; and the groove is provided with an O-shaped rubber sealing ring (3). The bearing support can replace the prior bearing support of the rear end cover of the automobile motor.
Description
Technical field:
The utility model relates to a kind of machine components, relates in particular to a kind of bearing pedestal.
Background technology:
As everyone knows, automobile current generator is a kind of generator that works long hours, and operational environment is more abominable, and along with the development of automobile to the lightness direction, the component structural design is compact more, and generator is no exception.
The quality of bearing is the comparison key for generator, and the reliability of bearing structure direct and bearing pedestal is closely related.At present, wave washer normally is installed in the bearing pedestal of rear end cap and is adopted the specific bearing of thickening to guarantee the reliability of automobile current generator rear end cap bearing, therefore processing and the assembly precision to bearing pedestal requires all than higher, and this mode has not only strengthened the length overall of generator but also increased the cost of generator; Simultaneously, because generator will be subjected to the extruding of wave washer in the middle (center) bearing outer ring that runs up, so can descend the useful life of bearing.
Summary of the invention:
At the above-mentioned defective that exists in the prior art, the utility model aims to provide and a kind ofly helps reducing the generator volume, reduces cost, and automobile current generator rear cap bearing support simple in structure.
To achieve these goals, the utility model by the following technical solutions: it comprises the bearing pedestal body; The dead eye surface that cooperates with bearing outer ring at the bearing pedestal body is provided with annular groove, is provided with O type rubber seal in this groove.
Compared with the prior art, therefore the utility model has the following advantages owing to adopted technique scheme:
1) adopt common standard rolling bearing just can satisfy instructions for use, and need not adopt the specific bearing of thickening, the axle that helps reducing generator is thought size and is reduced cost;
2) adopt O type rubber seal alternative wave packing ring to come the axial endplay of restrictive axes bearing outer-ring, not only can reduce the axial machining accuracy of dead eye and the requirement of assembly precision, and O type rubber seal can also stop bearing outer ring to slide, reduce the friction between bearing outer ring and the dead eye, thus the effect of playing vibration and noise reducing, prolonging bearing and bearing pedestal useful life.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of traditional bearing seat.
Among the figure: bearing pedestal body 1 annular groove 2 O type rubber seal 3 bearings 4 rotor axis of electric 5 wave washers 6
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment:
As shown in Figure 1: the dead eye surface at bearing pedestal body 1 is provided with annular groove 2, is provided with O type rubber seal 3 in this groove.
Fig. 2 and Fig. 1 contrast can be found the bearing pedestal of traditional structure is by being installed in the outer ring play that wave washer 6 in the dead eye limits bearing 4, therefore the required precision of the axial dimension of described dead eye is than higher; In addition, because the outer ring of rotor axis of electric 5 bearing 4 when high speed rotating will be subjected to the frequent extruding of wave washer 6, so the life-span of bearing 4 can be subjected to certain influence.And the utility model is owing to adopt O type rubber seal 3 alternative wave packing rings 6, utilize frictional resistance between O type rubber seal 3 and bearing 4 outer rings to come the axial endplay of restrictive axes bearing outer-ring, therefore the axial dimension of dead eye can shorten, and axially required precision also can be looser.
Claims (1)
1. an automobile current generator rear cap bearing support comprises the bearing pedestal body; It is characterized in that: be provided with annular groove (2) on the dead eye surface that bearing pedestal body (1) cooperates with bearing outer ring, be provided with O type rubber seal (3) in this groove.
