Abstract
A nozzle casing centering structure suitable for a supercharger comprises a fuel gas inlet housing, a nozzle casing and locating pins. The nozzle casing centering structure suitable for the supercharger is characterized in that at least four round locating holes evenly distributed along the circumference direction are formed in the fuel gas inlet housing, grooves are formed in the nozzle casing, the number and the positions of the grooves are corresponding to the number and the positions of the round locating holes, the fuel gas inlet housing is connected with the nozzle casing through the locating pins and screws, and a radial interval is formed between the bottom of each groove and the locating pin adjacent to each groove. According to the nozzle casing centering structure suitable for the supercharger, the number of the round locating holes evenly distributed along the circumference direction of the fuel gas inlet housing is four, the round locating holes are evenly distributed in cross mode, and centering of the nozzle casing and the fuel gas inlet housing is achieved due to the fact that the round locating holes are processed in the fuel gas inlet housing and the cross locating waist-shaped grooves are processed in the nozzle casing. When the nozzle casing and the fuel gas inlet housing are thermally expanded, no damage can be caused due to the fact that the locating grooves can freely slide relatively to the locating pins. Simultaneously, the nozzle casing is restrained in the circumferential direction due to fact that the locating holes are arranged in cross mode, and therefore high concentricity is kept, and the problems in concentric locating are solved.
Description
Technical field
The utility model relates to a kind of peculiar to vessel and machine vehicle turbocharger that is applicable to.
Background technique
The nozzle casing of pressurized machine is revolving parts, operating temperature reaches more than 400 ℃, its installation method adopts concentric circle seam positioning instant that nozzle casing is processed into round boss conventionally, fuel gas air admission shell end face is processed into circular groove, links together to realize the location and installation of nozzle casing behind boss and groove location.
Adopt nozzle casing concentric circle seam orientation type, due to work under bad environment, concentric circle seam swell increment is large, often causes nozzle casing and fuel gas air admission shell seam deformation and damage, and dismounting is very difficult.Accompanying drawing 1 and Fig. 2 have represented this situation.
Model utility content
The problems referred to above that exist for solving prior art, the utility model will design and a kind ofly can prevent the gross distortion of nozzle casing seam and fuel gas air admission shell seam and the nozzle casing adjective-centre structure that is applicable to pressurized machine of damage.
To achieve these goals, the technical solution of the utility model is as follows: a kind of adjective-centre structure of pressurized machine nozzle casing, comprises fuel gas air admission shell and nozzle casing and locating stud.It has following characteristics: fuel gas air admission shell is provided with at least four along the circumferential direction uniform circular positioning holes, has the groove corresponding with described circular positioning hole quantity and position on nozzle casing.Fuel gas air admission shell and nozzle casing interconnect by locating stud and screw.At the bottom of groove and between locating stud, leave radial clearance.On fuel gas air admission shell in present case, along the circumferential direction uniform circular positioning hole quantity is four, is cross uniform layout.At the bottom of groove and the radial clearance leaving between locating stud be at least 1mm
Compared with prior art, the utlity model has following beneficial effect:
Due to the utility model by processing circular positioning pin hole on fuel gas air admission shell, on nozzle casing, process cross location kidney slot and realize nozzle casing and the fuel gas air admission shell heart.When nozzle casing and fuel gas air admission shell thermal expansion, because locating slot can be free to slide with locating stud, therefore can not cause damage.Because location is cross state, nozzle casing is subject to circumferential constraint, therefore still can keep higher concentricity, has solved concentric locating problem simultaneously.Therefore the utility model has overcome the shortcoming of existing structure, cross location had both guaranteed the concentricity that nozzle casing is high, had avoided again gross distortion and the damage of nozzle casing seam and fuel gas air admission shell seam.
Accompanying drawing explanation
6, the total accompanying drawing of the utility model, wherein:
Fig. 1 is the structural representation of prior art.
Fig. 2 is the I place enlarged view of Fig. 1.
Fig. 3 is the schematic diagram of the adjective-centre structure of a kind of pressurized machine nozzle casing of the utility model.

Fig. 6 is the III place enlarged view of Fig. 5.
In figure: 1, nozzle casing, 2, fuel gas air admission shell, 3, locating stud.
Embodiment
The adjective-centre structure of this pressurized machine nozzle casing, comprises fuel gas air admission shell 2, nozzle casing 1 and locating stud 3.At least four of processing uniform circular positioning hole along the circumferential direction on fuel gas air admission shell 2.On fuel gas air admission shell 2 in present case, along the circumferential direction uniform circular positioning hole quantity is four, is cross uniform layout.On nozzle casing 1, open the groove corresponding with positioning hole quantity and position.At the bottom of groove and the radial clearance leaving between locating stud be at least 1mm.By locating stud 3 and screw, undertaken fuel gas air admission shell 2 and nozzle casing 1 to be located by connecting, thus the location of realizing nozzle casing 1.Adopt this cross cotter way centering new structure, owing to leaving gap at the bottom of groove and between locating stud, when part thermal expansion because locating slot can be free to slide with locating stud, therefore can not cause damage.Because location is cross state, part is subject to circumferential constraint, therefore still can keep higher concentricity, has solved concentric locating problem simultaneously.Therefore this invention has overcome the shortcoming of structure in the past, cross location had both guaranteed the concentricity that nozzle casing is high, had avoided again gross distortion and the damage of nozzle casing seam and fuel gas air admission shell seam.Concrete structure can be referring to Fig. 3, Fig. 4, Fig. 5, Fig. 6.
