Description
Technical Field
The utility model relates to a turbo charger technical field, in particular to casting integral type amortization cover pressure shell.
Background
The turbocharger is actually an air compressor that increases the intake air amount by compressing air. The engine uses the inertia impulse force of the exhaust gas from the engine to push the turbine in the turbine chamber, the turbine drives the coaxial impeller, the impeller presses the air sent by the air filter pipeline, and the air is pressurized and enters the cylinder. When the rotating speed of the engine is increased, the exhaust gas exhaust speed and the rotating speed of the turbine are also increased synchronously, the impeller compresses more air to enter the cylinder, the pressure and the density of the air are increased, more fuel can be combusted, the fuel quantity is correspondingly increased, the rotating speed of the engine is adjusted, and the output power of the engine is increased.
Automobile technology is gradually developed, automobiles with turbochargers are more and more popular, the demand for the superchargers is gradually increased, and in order to reduce the noise of the superchargers, a silencer structure is designed at the pressure end of the superchargers. In order to prevent the silencing cover from sliding after assembly, the silencing cover is fixed by using the elastic check ring, the elastic check ring is designed into a wave shape, so that the silencing cover can be effectively fixed, but great difficulty is brought to assembly, and the assembly can be completed only by flattening the wave shape. The traditional installation method needs to manually press the elastic check ring, so that the strength is high, the time consumption is long, the efficiency is low, impurities such as aluminum scraps are easily generated in the compressor shell when the check ring is manually knocked into the groove, and after the compressor shell is assembled on the supercharger, the performance of the whole compressor is influenced, and even key components such as an engine are damaged.
In order to overcome the defects of low efficiency and high risk of the traditional assembly method, the integrated silencing cover pressing shell is provided.
Disclosure of Invention
The utility model aims at overcoming the defect that prior art exists, providing a casting integral type amortization cover pressure shell.
Realize the utility model discloses the technical scheme of purpose is: the utility model provides a casting integral type amortization cover presses shell, has and presses the shell body, it is provided with an annular air inlet on the shell body to press, the inboard of pressing the shell body is provided with the loop forming element, the coaxial unsettled setting of loop forming element and air inlet with press the inside linking firmly of shell body through the splice bar of a plurality of equipartitions, be provided with round annular amortization cover in the air inlet, amortization cover and pressure shell body integrated into one piece.
Furthermore, a circle of return channel is formed between the outer side of the annular piece and the inner side wall of the pressing shell body.
Furthermore, the inner ring of the silencing cover inclines towards the annular piece to form a conical surface.
Further, an impeller cavity is formed in the tail end of the annular part in the pressure shell body.
After the technical scheme is adopted, the utility model discloses following positive effect has:
(1) The utility model discloses a casting integral type pressure shell, pressure shell are from taking amortization cover structure, and simple structure reduces unnecessary assembly process, reduces the inefficacy risk that the assembling process brought, and cost reduction reaches the function of noise reduction simultaneously.
Drawings
In order that the manner in which the above recited features of the present invention can be understood in detail, a more particular description of the invention, briefly summarized above, may be had by reference to embodiments, some of which are illustrated in the appended drawings
Fig. 1 is a schematic structural view of the present invention;
fig. 2 is a schematic view of an original press shell structure.
Detailed Description
Example 1
See fig. 1, the utility model discloses have and press shell body 1, press shell body 1 to go up and be provided with an annular air inlet 2, press shell body 1's inboard to be provided with loop forming element 3, loop forming element 3 and the coaxial unsettled setting of air inlet 2, the splice bar 4 through a plurality of equipartitions links firmly with pressing shell body 1 is inside, is provided with round annular amortization cover 5 in the air inlet 2, amortization cover 5 and press shell body 1 integrated into one piece. The silencer is provided with the silencing cover structure, the structure is simple, and unnecessary assembly processes are reduced. A circle of backflow channel 6 is formed between the outer side of the annular piece 3 and the inner side wall of the pressure shell body 1 and used for gas backflow. The inner ring of the silencing cover 5 inclines towards the annular part 3 to form a conical surface. The tail end of the annular part 3 in the pressure shell body 1 is provided with an impeller cavity 7. The outer end of the air inlet 2 is provided with a circle of flange.
The utility model discloses a theory of operation does: casting integral type pressure shell, pressure shell are from taking amortization cover structure, and simple structure reduces unnecessary assembly process, reduces the inefficacy risk that the assembling process brought, and cost reduction reaches the function of noise reduction simultaneously.
Referring to fig. 2, in the original pressure shell structure, the traditional pressure shell and silencing cover structure, the silencing cover is fixed on the pressure shell through the elastic retainer ring, and the assembly can be completed only by flattening the waveform during assembly, which brings great difficulty to the assembly. The traditional installation method needs to manually press the elastic check ring, so that the strength is high, the time consumption is long, the efficiency is low, impurities such as aluminum scraps are easily generated in the compressor shell when the check ring is manually knocked into the groove, and after the compressor shell is assembled on the supercharger, the performance of the whole compressor is influenced, and even key components such as an engine are damaged.
The above-mentioned embodiments further describe the objects, technical solutions and advantages of the present invention in detail, it should be understood that the above-mentioned embodiments are only specific embodiments of the present invention, and are not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
