Description

A kind of sealing structure of turbocharger
Technical field
This utility model belongs to field of mechanical technique, relates to a kind of turbocharger, particularly to a kind of turbocharger Sealing structure.
Background technology
Along with growth and the increase of high-performance low energy consumption engine demand of auto output, use sending out of turbocharger Motivation gets more and more, but its problem revealing oil in use is increasingly appeared suddenly, under turbocharger operation state Rotating speed be up to 40000~220000r/min, continuously run under high-speed and high-temperature for a long time, working condition is very severe, too high Temperature can make sealing oil film evaporating, and abrasion aggravation, operational security is on the hazard.And the compressor casing of existing turbocharger with Being sealed by O-shaped rubber ring between bearing body, this sealing structure, under the influence of for a long time by high pressure and high temperature, may go out Existing crimp and high temperature ageing, cause the sealing of supercharger air compressor end to be deteriorated.
Summary of the invention
The purpose of this utility model is for the above-mentioned problems in the prior art, it is provided that a kind of good seal performance The sealing structure of turbocharger.
The purpose of this utility model can be realized by following technical proposal: the sealing structure of a kind of turbocharger, should Turbocharger includes compressor casing, bearing body and is fixed with the rotating shaft of impeller, described rotating shaft be arranged in compressor casing and In bearing body, it is characterised in that be respectively provided with outwardly convex and the flange cooperated on described bearing body and compressor casing Portion, is fixed by pressing plate between described compressor casing and bearing body, and pressing plate is by the screw pressure being connected on compressor casing Tightly, between two flange parts on described bearing body and compressor casing, place is provided with sealed paper packing ring, and described rotating shaft is positioned at It is provided with oil sealing cap between impeller and bearing body, between described oil sealing cap and bearing body and rotating shaft, is formed with full lubricating oil Oil pocket, fixed by circlip between described oil sealing cap and bearing body.
It is provided with sealed paper packing ring, due to it between compressor casing and bearing body in the sealing structure of this turbocharger Have oil resistant, high temperature resistant, deflection is little, low cost and other advantages, and therefore life-time service can ensure that supercharger portion leaks gas.
In the sealing structure of above-mentioned a kind of turbocharger, arrange between upper surface and the bearing body of described oil sealing cap There is O type rubber seal, between right side and the bearing body of described oil sealing cap, be also equipped with sealed paper packing ring.
In the sealing structure of above-mentioned a kind of turbocharger, for tiltedly carving face between described circlip and bearing body Coordinate.The design of this structure makes the connection between circlip and bearing body more firm.
Compared with prior art, the sealing structure of this turbocharger has the advantage that
1, sealed paper packing ring it is provided with between compressor casing and bearing body, owing to it has oil resistant, high temperature resistant, deflection Little, low cost and other advantages, therefore life-time service can ensure that supercharger portion leaks gas.
2, traditional screw is replaced to connect fixing oil sealing cap and bearing body by circlip so that it can be with O type The rubber seal radial seal to oil sealing cap, with the high temperature resistant lower better seal paper washer circumferential seal to oil sealing cap, because of This not only simplify structure, and improves sealing.

Detailed description of the invention
The following is specific embodiment of the utility model and combine accompanying drawing, the technical solution of the utility model is made further Description, but this utility model is not limited to these embodiments.
As it is shown in figure 1, the sealing structure of this turbocharger, this turbocharger include compressor casing 1, bearing body 2 with And it being fixed with the rotating shaft 4 of impeller 3, rotating shaft 4 is arranged in compressor casing 1 and bearing body 2, on bearing body 2 and compressor casing 1 respectively There is outwardly convex and the flange part 5 cooperated, fixed by pressing plate 6 between compressor casing 1 and bearing body 2, and pressing plate 6 leads to Crossing the screw 7 being connected on compressor casing 1 to compress, between two flange parts 5 on bearing body 2 and compressor casing 1, place is provided with close Envelope paper washer 8, rotating shaft 4 is provided with between impeller 3 and bearing body 2 oil sealing cap 9, oil sealing cap 9 and bearing body 2 and rotating shaft 4 Between be formed full lubricating oil oil pocket 10, fixed by circlip 11 between oil sealing cap 9 and bearing body 2.
In order to the sealing effectiveness making turbocharger is more preferable, between upper surface and the bearing body 2 of its oil sealing cap 9, it is provided with O Type rubber seal 12, is also equipped with sealed paper packing ring 8 between right side and the bearing body 2 of oil sealing cap 9.
Describe in detail further, for tiltedly carving face between circlip 11 and the bearing body 2 in the sealing structure of this turbocharger Coordinate.
Specific embodiment described herein is only to this utility model spirit explanation for example.This utility model institute Belong to those skilled in the art described specific embodiment to make various amendment or supplement or use similar Mode substitute, but without departing from spirit of the present utility model or surmount scope defined in appended claims.
Although the most more employing compressor casing 1, bearing body 2, impeller 3, rotating shaft 4, flange part 5, pressing plate 6, screw 7, the term such as sealed paper packing ring 8, oil sealing cap 9, oil pocket 10, circlip 11, O type rubber seal 12, but be not precluded from using The probability of other term.Use these terms to be only used to more easily and describe and explain essence of the present utility model;? They are construed to any additional restriction is all contrary with this utility model spirit.
