Description
Technical field
The utility model belongs to engine oil inlet pipe installation bolt technical field, and in particular to a kind of booster with filter screen
Oil inlet pipe hollow bolt.
Background technology
The turbocharger being widely used at present is the exhaust energy using engine emission, promotes the turbine of turbine high
Speed rotation, the impeller of the compressor coaxial with turbine is driven to rotate at a high speed by middle mandrel, and then by after compresses fresh air
The compressor mechanical of supply engine work.Turbocharger can make the increase of engine aeration quantity, be available for more fuel oils abundant
Burning, so as to improve the power of engine and efficiency, reduce harmful components discharge.Especially in highlands in use, can
The air pressure of effective compensation altitude environment declines and causes the influence of power drop.
Turbocharger is more accurate parts, and in its work, central mandrel, turbine, wheel speed may be up to 2
Ten thousand revs/min, rotation can produce substantial amounts of heat and abrasion at a high speed, therefore the lubrication at turbocharger mandrel position is of crucial importance
, meanwhile, mandrel design is relatively thin, therefore requires high to the cleannes of lubricating oil.
The lubrication of conventional turbocharger generally borrows engine oil gallery fuel feeding, and turbocharger lubricating oil passes through oil-feed
Pipe enters directly into intermediate, and mandrel, bearing etc. are lubricated, impurity, the abrasive dust not filtered out in oil duct by machine filter, pole
Mandrel position easily is entered, causes the inordinate wear of mandrel, or even off-axis.
Utility model content
The utility model devises a kind of sucker of supercharger hollow bolt with filter screen, solves turbocharger mandrel
The problem of cleanliness of lubricating oil deficiency of bearing portion causes the inordinate wear of turbocharger mandrel to be failed.
In order to solve above-mentioned technical problem, the utility model employs following scheme：
A kind of sucker of supercharger hollow bolt with filter screen, including hollow bolt body, it is characterised in that also including cylinder
Type filter screen；The cartridge filter is arranged in the cavity structure of the hollow bolt body, and barrier is in the hollow bolt sheet
Between the oil inlet and oil-out of body.
Further, one end of the cartridge filter is provided with support ring, and the cartridge filter is fixed by support ring
On the hollow bolt body.
Further, the cartridge filter is both ends cylindrical structure with the end, and its both ends end face and side wall are processed
There is filter screen mesh.
Further, the hollow bolt body includes bolt head and bolt shank, and the bolt shank is machined with axial direction
Cavity structure, the openend of cavity structure is oil inlet；The bolt shank is also machined with the through hole of radial direction, radial direction through hole
Penetrated with the axial cavity structure, so as to form oil-out.
Further, the hollow bolt body be provided with the oil inlet one end end plane on be machined with counter bore structure with
With the support ring cooperating of the cartridge filter.
During assembling, cartridge filter is loaded in the cavity structure of hollow bolt body axial direction, meanwhile, cartridge filter outer end
Support ring is pressed into and is clamped in the counter bore structure on hollow bolt body arrival end end plane.Support ring and counter bore structure
Cartridge filter is not only fixed in hollow bolt body by cooperation, while also acts the effect of sealing.
When turbocharger operation, come from the machine oil of engine cylinder-body oil duct, first entering in hollow bolt body
Oil port enters in hollow bolt body after the end face filter screen of cartridge filter filters for the first time, again through cartridge filter side wall and
After second of the filtering of other end filter screen, flowed out by the oil-out of hollow bolt body, be sent to the oil inlet pipe of turbocharger
It is interior.
The sucker of supercharger hollow bolt with filter screen has the advantages that：
（1）The utility model is under the premise of it to conventional turbocharger need not significantly change, effectively to entering
The lubricating oil of turbocharger mandrel bearing portion is filtered, and is reached and is improved its cleannes, prevents abrasive dust, foreign matter impurity etc. from entering
Enter the purpose that mandrel causes the situation of mandrel inordinate wear to occur.
（2）Hollow bolt and cartridge filter of the present utility model, structure design is simple, and technique is realized convenient, it is only necessary to is passing
System turbocharger oil inlet pipe hollow bolt end face processing counterbore, and cartridge filter is fitted in counterbore, installation is changed
It is convenient, it is time saving and energy saving.
Brief description of the drawings
Fig. 1：The structural representation of sucker of supercharger hollow bolt of the utility model with filter screen.
Description of reference numerals：
1-hollow bolt body；11-oil-out；12-oil inlet；2-cartridge filter；21-support ring.
Embodiment
Below in conjunction with the accompanying drawings, the utility model is described further：
Fig. 1 shows a kind of sucker of supercharger hollow bolt with filter screen, including hollow bolt body 1 and cartridge filter
2, cartridge filter 2 is arranged in the axial cavity of hollow bolt body 1.
Hollow bolt body 1 includes bolt head and bolt shank.Bolt shank is machined with axial cavity structure, cavity
The openend of structure is oil inlet 12.Bolt shank is also machined with the through hole of radial direction, radial direction through hole and the cavity structure of axial direction
Insertion, so as to form oil-out 11.Hollow bolt body 1 is provided with one end end plane of oil inlet 12 and is machined with counter bore structure
With the cooperating of support ring 21 with the outer end of cartridge filter 2.Cartridge filter 2 is that both ends end face and side wall are machined with mesh
