Description
Technical field
It the utility model is related to automobile current generator technical field, more particularly to a kind of automobile current generator rear cover waterproof structure.
Background technology
In current generator, bearing chamber that bearing covers after passing through, now the fully wrapped around split bearing of bearing chamber is simultaneously
Form the structure of opposing seal.When generator operation is in the bad working environments such as muddy road or rainy day, hold inside bonnet bearing chamber
Easily enter sewage, if can not exclude these sewage in time can cause ponding, the sealing ring of bearing can cause in bearing because of water inlet
Failure is got rusty in portion or grease oozes out, and in turn results in the not smooth abnormal sound of generator operation and ultimate failure.Therefore quick discharge axle is needed
The ponding of interior is held, avoids bearing from being damaged.
Utility model content
The utility model provides a kind of automobile current generator rear cover waterproof structure, can quickly discharge the ponding in bearing chamber,
The purpose is realized by the through hole on cover plate and the guiding gutter being obliquely installed.
In order to achieve the above object, the utility model adopts the following technical scheme that：Including cover plate and positioned at the cover plate
Side is provided with perforate to the protective cover away from cover plate direction extension, the protective cover circumference, it is characterised in that：Also wrap
Include bearing chamber and axis hole, through hole is provided with the cover plate below the axis hole, the bearing chamber madial wall is provided with and led
Chute, the guiding gutter connect with the through hole and run through the bearing chamber, along guiding gutter described in the bearing chamber bearing of trend
One end is less than the other end.
Thus, the ponding on bearing is fallen in rotary course on bearing chamber madial wall, with the product on bearing chamber madial wall
Water is slipped in guiding gutter together, is finally discharged from guiding gutter one end.
As a preferred embodiment, the guiding gutter is less than close to described through hole one end close to described perforate one end.
Thus, ponding is discharged from guiding gutter close to protective cover one end.
As a preferred embodiment, the guiding gutter is less than close to described perforate one end close to described through hole one end.
Thus, through hole one end discharge of the ponding from guiding gutter on cover plate.
As a preferred embodiment, the angle of inclination of the guiding gutter is 2-4 °.
Thus, on the premise of the ponding velocity of discharge is ensured, the size of guiding gutter and through hole is reduced.
As a preferred embodiment, the guiding gutter is provided with choker bar close to described perforate one end.
Thus, fall on protective cover, be convenient to clean when preventing ponding from discharging.
As a preferred embodiment, the cross sectional shape of the guiding gutter is circular arc or ellipse arc or V-arrangement.
As a preferred embodiment, the through hole is round hole.
To sum up, the ponding on bearing is fallen in rotary course on bearing chamber madial wall, with the product on bearing chamber madial wall
Water is slipped in guiding gutter together, is finally discharged from guiding gutter one end, is avoided bearing chamber internal water accumulation and bearing arrangement is caused brokenly
It is bad, extend the physical life of generator.
Brief description of the drawings
Fig. 1 is structural front view of the present utility model；
Fig. 2 is structural side view of the present utility model；
Fig. 3 is enlarged drawing at the first embodiment A in Fig. 2；
Fig. 4 is enlarged drawing at second of embodiment A in Fig. 2.
Label is as follows in figure：
1. cover plate, 2. protective covers, 21. perforates, 3. bearing chambers, 4. axis holes, 5. through holes, 6. guiding gutters.
Embodiment
The utility model is described in further detail for middle embodiment below in conjunction with the accompanying drawings.
As shown in Figures 1 to 4, the generator rear cover includes cover plate 1 and positioned at the side of cover plate 1 to away from the side of cover plate 1
To the protective cover 2 of extension, the circumference of protective cover 2 is provided with perforate 21, and perforate 21 is uniformly distributed along in the circumference of protective cover 2.Additionally
Including bearing chamber 3 and axis hole 4, bearing passes through bearing chamber 3 and axis hole 4.Through hole 5 is provided with the cover plate 1 of the lower section of axis hole 4,
The madial wall of bearing chamber 3 is provided with guiding gutter 6, and guiding gutter 6 connects with through hole 5 and runs through bearing chamber 3, along the bearing of trend of bearing chamber 3
The one end of guiding gutter 6 is less than the other end.During use, when ponding be present in bearing chamber 3, the ponding on bearing is in rotary course
In fly on the madial wall of bearing chamber 3 and be slipped to water conservancy diversion under gravity with the ponding on the madial wall of bearing chamber 3
In groove 6, finally discharged from the one end of guiding gutter 6.
In the first embodiment as shown in Figure 3, guiding gutter 6 is less than close one end of through hole 5 close to the one end of perforate 21, now
Ponding is discharged from guiding gutter 6 close to the one end of protective cover 2, and without the through hole 5 on cover plate 1, drainage speed is faster.As shown in Figure 4
Second of embodiment in, guiding gutter 6 is less than close to the one end of perforate 21 close to the one end of through hole 5, and ponding is from guiding gutter 6 close to cover plate
The one end of through hole 5 discharge on 1.Guiding gutter 6 is provided with choker bar close to the one end of perforate 21, and choker bar is the bulk for stopping guiding gutter 6
Thing, for preventing ponding from being flowed out from the side, fall on protective cover 2 when thus preventing ponding from discharging and pollute protective cover 2, save
The scavenging period of protective cover 2.
The angle of inclination of guiding gutter 6 is 2-4 °, on the premise of the ponding velocity of discharge is ensured, reduces guiding gutter 6 and through hole 5
Size.When angle of inclination is excessive, to ensure the water conservancy diversion effect of open guiding gutter, the sectional dimension of guiding gutter 6 is larger, can be to knot
The intensity of structure adversely affects.
The cross sectional shape of guiding gutter 6 is circular arc or ellipse arc or V-arrangement, and through hole 5 is round hole.
Described above is only to explanation of the present utility model so that those of ordinary skill in the art's can completely implements this
Scheme, but be not to limitation of the present utility model, those skilled in the art can be as needed after this specification is read
The modification of no creative contribution is made to the present embodiment, these are all without creative modification, but as long as in this practicality
All protected in new right by Patent Law.
