Description
Technical field
The utility model relates to the parts in a kind of turbosupercharger, relates in particular to a kind of Diffuser that links to each other with impeller chimney at the turbine rotor shaft end.
Background technique
Turbosupercharger is quite extensive in the use of current society, the fast development of domestic engine technology and the increasingly stringent of Abgasgesetz, and it is universal to make engine turbine pressurized machine technology attain the Way rapidly, also more strict to the requirement of engine turbine pressurized machine.As everyone knows, turbosupercharger is widely used in being connected with internal-combustion engine, and the blade of supplying with and drive turbine from the waste gas of internal-combustion engine drives the compressor impeller rotation again.Compressor impeller contracts air pressure, and that it is discharged into corresponding cylinder combustion is indoor.In recent years, motor especially diesel engine supercharging rate increases substantially, but is subjected to the restriction of turbocharger arrangement and matching properties, needs the structure of turbosupercharger more and more compacter.End at the central shaft of turbosupercharger is equipped with bearing assembly and Diffuser, is connected with impeller chimney and pressure side cartridge housing on the Diffuser.On Diffuser, be fixed with blade,, can make compressor performance curves be similar to left and right sides translation, influence the working efficiency of turbosupercharger owing to adjust blade import geometric angle; Diffuser links to each other the anti-asthma vibrating effect of the structure influence impeller chimney of Diffuser with impeller chimney simultaneously.In the present disclosed data, Chinese patent application is arranged: " rotatable vane diffuser of centrifugal compressor (CN101818749A) ", mainly be with dividing plate that compressor scroll is connected on be connected with the trough of belt runner, be connected with band pin crank on being connected band diffuser vane active rotating shaft.This active rotation is connected with dividing plate, and active rotating shaft connects electric actuator by the connecting rod on the compressor scroll of ining succession through crank bindiny mechanism again.This structure has reasonable aeroperformance and higher wear resistance and elasticity, but structure is too complicated.
Summary of the invention
It is a kind of simple in structure that the utility model provides, and anti-asthma is effective, and noise is low, thereby improved the working life and the using effect of turbosupercharger; The anti-asthma effect that has solved the Diffuser that is applied in turbosupercharger that prior art exists is bad, baroque technical problem.
Above-mentioned technical problem of the present utility model solves by following technical proposals: a kind of Diffuser that is used on the turbosupercharger, comprise the Diffuser main body, an end face in the Diffuser main body is provided with blade, it is characterized in that: described another end face of Diffuser main body is provided with junction surface, described junction surface is between the center hole and outer rim of described Diffuser main body, side at described junction surface is provided with bolt hole and technology groove, on described junction surface, be provided with annular groove, described spiro keyhole position is in center hole one side of Diffuser main body, described annular groove is positioned at outward edge one side of Diffuser main body, the width of described junction surface is not less than half of described Diffuser bulk end face width degree, is provided with seal ring in the described annular groove.The Diffuser main body in the form of a ring, on an end face of annular body, blade is set, another end face in annular body is used for fixing connection pressure side cartridge housing and anti-asthma impeller chimney, this fixedly has the anti-asthma impeller chimney by bolt on the end face, simultaneously junction surface is set on stationary plane, junction surface is used for linking to each other with the pressure side cartridge housing, and the area that increases junction surface has just increased the area of contact of Diffuser and pressure side cartridge housing, make to be connected firmly, work well.Simultaneously, the pressure side cartridge housing is connected with an end of anti-asthma impeller chimney simultaneously, and the pressure side cartridge housing connects firm, has also just improved the anti-asthma function of anti-asthma impeller chimney.Annular groove is set on junction surface simultaneously, and seal ring is set in annular groove simultaneously, improve sealing effect, the also effectively anti-asthma effect that improved has simultaneously improved the stability of equipment operation, makes service life of equipment longer.
As preferably, described blades height is 11mm～16mm, and the angle between the line at the center of the end of adjacent two blades and Diffuser main body is 18.5 °～19.5 °.Adjacent two blades near the end at center all and the line of centres, the angle between two lines is 18.5 °～19.5 °.Blades height on the Diffuser main body and angle all can influence the working efficiency of gas compressor, and above-mentioned angle has well guaranteed the high workload efficient of gas compressor.
As preferably, the width of described junction surface is 65mm～75mm.The area of junction surface is 1/2～2/3 of a Diffuser main body, has guaranteed the anti-asthma performance of connection stability and anti-asthma impeller chimney.
As preferably, the bottom land width of described annular groove is greater than the A/F of described annular groove.The annular groove opening of fixed seal ring is little, and bottom land is wide to have guaranteed to say that seal ring is well fixing, improves sealing effect.
As more preferably, the cross section of described annular groove is the right-angled trapezium shape.Easily manufactured, machine shaping is convenient.
Therefore, a kind of Diffuser that is used on the turbosupercharger of the present utility model possesses following advantage: increased the junction surface of Diffuser, made that connection is more firm; On junction surface, seal simultaneously, improved the anti-asthma effect of anti-asthma impeller chimney by seal ring, thus the working life of also having improved equipment.
