Abstract
The invention discloses a front end cover of a generator. The front end cover includes an end cover body. Hanging horns, end cover installation holes, a protective cover and a shaft hole are arranged on the end cover body. A boss is arranged at the middle part of the protective cover. The shaft whole penetrates the boss. A plurality of connection holes are arranged in the boss and distributed evenly in the boss. The two hanging horns are also arranged on the end cover body and each hanging horn is provided with a hanging-horn hole. Reticular ventilation holes are distributed evenly in the protective cover. The front end cover of the generator effectively improves the assembly strength of the generator and increases the use reliability of the generator.
Description
Technical field
The present invention relates to a kind of automobile current generator accessory, particularly front end of shield.
Background technology
Generator is the plant equipment that the energy conversion of other form is become to electric energy, and electric generators for automobile is the main power source of automobile, and its function is in the time of normal working of engine, to all power consumption equipment power supplies except starter motor, charges a battery simultaneously; Conventionally generator front and back end is that front end housing and rear end cap are assembled together, and front end housing and rear end cap play a part support rotor, stator, rectifier and brush assembly of electric.Current front end housing protective cover has many ventilation holes, and protective cover central authorities have axis hole, and this directly causes the axis hole insufficient strength that coordinates with bearing cap, rotor on front end housing large, has affected the use of generator.
Summary of the invention
The object of the invention is to overcome existing front end of shield upper shaft hole in prior art coordinates insufficient strength large with bearing cap, rotor, easily cause the stress of front end housing protective cover to concentrate, affect the deficiency of the use of engine, a kind of front end of shield is provided, this front end of shield simplicity of design, coordinates the reliability that intensity is higher, improved generator with bearing cap, rotor.
In order to realize foregoing invention object, the invention provides following technical scheme:
A kind of front end of shield, comprises end cap body, and described end cap body is provided with hangs angle, end cap installing hole, protective cover and axis hole, in the middle of described protective cover, is provided with boss, and described axis hole runs through described boss, and described boss is provided with some connecting holes.
Connecting hole on boss is set in the middle of the protective cover by end cap body, front end housing and bearing cap, rotor is assembled together with bolt, intensity is significantly improved, and generator uses more reliable.
Preferably, described connecting hole is evenly distributed on described boss.
Preferably, described end cap body is provided with two and hangs angle, and wherein each extension angle is provided with Gua Jiao hole.
Preferably, on described protective cover, be evenly distributed with netted ventilation hole.
Compared with prior art, beneficial effect of the present invention:
Front end of shield of the present invention, by boss is set in the middle of end cap body protective cover, then together with the axis hole of front end housing is passed through to bolts assemblies with bearing cap, rotor, has improved assembling intensity; Being uniformly distributed of connecting hole on boss, the erection stress having reduced between front end housing and rotor is concentrated, the useful life of having improved generator.

Embodiment
Below in conjunction with test example and embodiment, the present invention is described in further detail.But this should be interpreted as to the scope of the above-mentioned theme of the present invention only limits to following embodiment, all technology realizing based on content of the present invention all belong to scope of the present invention.
As shown in Figure 1-2, a kind of front end of shield, comprises end cap body 1, described end cap body 1 is provided with hangs angle 2, end cap installing hole 4, protective cover 5 and axis hole 6, in the middle of described protective cover 5, be provided with boss 7, described axis hole 6 runs through described boss 7, and described boss 7 is provided with some connecting holes 8.
Connecting hole 8 in the present embodiment on boss is evenly distributed on boss 7, and the erection stress having effectively reduced between front end housing and rotor is concentrated.End cap body 1 is provided with two and hangs angle 2, and wherein each extension angle 2 is provided with Gua Jiao hole 3, and on protective cover 5, is evenly distributed with netted ventilation hole 9.
Front end of shield of the present invention, by the middle of the protective cover 5 at end cap body 1, boss 7 being set, then together with the axis hole of front end housing 6 is passed through to bolts assemblies with bearing cap, rotor, has improved the assembling intensity of generator.
