Abstract
Connection structure of turbo charger compressor spiral case and bearing body, on current compressor spiral case basis, redesign compressor spiral case is connected and location structure with the bearing body, design into the chuck structure with compressor spiral case flange face, two arc positioning groove of design on the bearing body, the structural style of chuck boss cooperates with the bearing body terminal surface through being direct, the utilization takes the bolt of mounting flange dish to carry out axial fixity to compressor spiral case and bearing body, finally realize turbo charger compressor spiral case and the quick installation of bearing body and pinpointing and the mistake proofing of installation angle through this kind of simple structure.
Description
Technical field
This utility model relates to turbo-charger technical field, particularly the attachment structure of a kind of Compressor volute of turbocharger and bearing body.
Background technology
Turbocharger is to utilize turbine structure that the gas internal energy of engine discharging tail gas is converted into rotating mechanical energy, by the compressor impeller coaxial with turbine, rotating mechanical energy is converted to the gas internal energy of engine aspirating system again, increase the air inflow of electromotor, improve a kind of energy saver of HP, hp/litre.
Turbocharger is mainly made up of parts such as compressor volute, bearing body, turbine box, turbine, compressor impeller and executors, novel turbocharger also arranges the electric control element that some are relevant, and compressor volute is one of important component part of turbocharger, it is not only the critical elements of Capability of Compressor, also it is the main body of carrying related elements or electric control element, and the location of blower outlet angle position more affects the integral layout of electromotor.
Existing novel turbocharger is all with relevant electronic component, the turbocharger such as VNT, the WGT such as variable area, all on compressor volute carrier ad-hoc location, devise control element, and the change controlling element angle position will directly affect the performance of supercharger.
Compressor volute fixing to turbocharger in the design of Compressor volute of turbocharger and angle location and running in sum, even for haircuting, motivation all plays vital effect.
Bearing body 2 as shown in Figure 7, is fixedly connected on compressor volute 1 by the connected mode that existing novel turbocharger compressor volute and bearing body are fixed by plain bolt 5 and pressing plate 4. This connected mode is primarily present following several drawback:
1, installation is complicated, part is more and palpus specialized designs pressing plate;
2, installing locating surface and be difficult to centering, when particularly to blower outlet Existential Space angle, anthropic factor is bigger, one to property is poor, and adopts joint face inside compressor volute to add dowel device, then structure is complicated, processing relatively difficult, precision is difficult to ensure that, not easily installs;
3, anti-axial rotation moment is less, it is easy to produces relative movement, affects booster performance, particularly the performance with electric control gear supercharger.
Summary of the invention
The purpose of this utility model is overcome the above-mentioned deficiency of prior art and provides the attachment structure of a kind of Compressor volute of turbocharger and bearing body.
The technical solution of the utility model is: the attachment structure of Compressor volute of turbocharger and bearing body, on existing compressor volute basis, redesign connection and the location structure of compressor volute and bearing body, compressor volute flange face is designed to chuck structure, bearing body designs two arc positioning grooves, directly coordinated with bearing body end face by the version of chuck boss, utilize the bolt with locating flange dish that compressor volute and bearing body are carried out axial restraint, Compressor volute of turbocharger and the Fast Installation of bearing body and being accurately positioned and mistake proofing of setting angle is realized eventually through this simple structure.
Its concrete structure is as follows:
At link four threaded chuck boss of design of compressor volute with bearing body, it is the first chuck boss, the second chuck boss, the 3rd chuck boss and the 4th chuck boss respectively.
Link two arc positioning grooves of design at bearing body with compressor volute, respectively the first arc positioning groove and the second arc positioning groove, first arc positioning groove corresponding with the first chuck boss on compressor volute, the second arc positioning groove is corresponding with the second chuck boss on compressor volute.
Compressor volute is connected fixing with bearing body by four bolts with locating flange dish, during connection, locating flange dish on two of which bolt respectively falls in the first arc positioning groove of bearing body and the bottom end face of the second arc positioning groove, each serving as location and the effect compressed, two other bolt only serves the effect of compression.
This utility model compared with prior art has a characteristic that
1, the attachment structure that this utility model provides is adopted, the Fast Installation that form part simple, required is less, installation effectiveness is high, can quickly meet various complicated Compressor volute of turbocharger is accurately positioned and mistake proofing with exit angle, production efficiency is greatly improved, reduce work degree, it is easy to produce, assemble, is beneficial to enterprise and drops this.
Below in conjunction with the drawings and specific embodiments, detailed construction of the present utility model is further described.

Detailed description of the invention
The attachment structure of Compressor volute of turbocharger and bearing body, at link four threaded chuck boss of design of compressor volute 1 with bearing body 2, it is the first chuck boss 1-1, the second chuck boss 1-2, the 3rd chuck boss 1-3 and the 4th chuck boss 1-4 respectively.
Link two arc positioning grooves of design at bearing body 2 with compressor volute 1, respectively the first arc positioning groove 2-1 and the second arc positioning groove 2-2, first arc positioning groove 2-1's is corresponding with the first chuck boss 1-1 on compressor volute 1, and the second arc positioning groove 2-2 is corresponding with the second chuck boss 1-2 on compressor volute 1.
Compressor volute 1 is connected fixing with bearing body 2 by four bolts 3 with locating flange dish 3-1, during connection, locating flange dish 3-1 on two of which bolt 3 respectively falls in the bottom end face of the first arc positioning groove 2-1 and the second arc positioning groove 2-2 of bearing body 2, each serving as location and the effect compressed, two other bolt 3 only serves the effect of compression.
