Abstract
The utility model provides a volute assembling type embedded sleeve which comprises a fixed ring and an inner sleeve, wherein a radiating rib is arranged at the front end of the fixed ring; the inner sleeve is connected with the inner side of the fixed ring; the radiating rib is arranged outside the inner sleeve; the radiating rib on the fixed ring is embedded into a volute; and the fixed ring is fixed on the volute through a bolt. The volute assembling type embedded sleeve provided by the utility model is fixed on the volute through the bolt, is made of a special heat-resisting corrosion-resisting material different from the material of the volute and is suitable for a working condition above 850 DEG C; the heat transfer and deformation volume of the volute are reduced; the probability of polishing the volute by a turbine blade is reduced; a working clearance between the turbine blade and the volute is reduced; the efficiency of a whole machine is increased; and the embedded sleeve is mounted on the volute through the bolt and can be timely detached and replaced, thereby prolonging the service life of a whole supercharger.
Description
Technical field
The utility model belongs to the automotive fittings fitting field, relates to a kind of volute assembling type edge cover.
Background technique
Volute on the pressurized machine is a vitals.The high temperature and high pressure gas that it can be discharged motor equably water conservancy diversion in the nozzle and turbine blade of whole circle.The tradition volute does not contain structure of mosaic, adopts a kind of material, and does not have heat-insulating structure, can only adapt to the operating temperature below 700 ℃, and turbine is 0.7～1.25mm with the working clearance of edge inner room.Volute work under high temperature and high pressure environment for a long time, the surface produces the phosphorous oxide distortion, produces the gap between the meridian line that makes turbine blade and the turbine meridian line and changes, and causes the part gap too small, causes that interior meridian plane of turbine blade and volute or endoporus collide; If this gap is excessive, leak volume is just big, causes the efficient of complete machine to reduce.
The model utility content
The technical problem that the utility model will solve is to overcome existing defective, a kind of volute assembling type edge cover is provided, through being bolted on the volute; Employing is different from the special material of volute and processes; Can adapt to working environment more than 850 ℃, reduce the heat transfer and the amount of deformation of volute, reduce the probability that turbine blade is wiped shell; Reduce the meridianal working clearance in turbine blade and the volute simultaneously, improved the efficient of complete machine.
In order to solve the problems of the technologies described above, the utility model provides following technological scheme:
A kind of volute assembling type edge cover comprises retaining ring and interior cover, and the retaining ring front end has radiating fin, and the retaining ring inboard is connected with interior cover, and there is radiating fin in the outside of interior cover; Radiating fin on the retaining ring embeds volute; Retaining ring is through being bolted on the volute.
Further, retaining ring and interior cover integral body process, and are " protruding " font.
Further, retaining ring and interior cover are through the draw-in groove assembly unit, and interior cover is fixed on volute by retaining ring.
Further, the radiating fin outside the interior cover does not contact with volute.
Further, the working clearance between volute assembling type edge cover and the turbine blade is 0.4mm～0.6mm.
A kind of volute assembling type edge of the utility model cover through being bolted on the volute, adopts the special heat resisting corrosion-proof corrosion material that is different from volute to process; Can adapt to working environment more than 850 ℃, reduce the heat transfer and the amount of deformation of volute, reduce the probability that turbine blade is wiped shell; Reduce the working clearance of turbine blade and volute simultaneously, improved the efficient of complete machine, through bolts assemblies on volute; Timely dismounting and change, thus working life of pressurized machine complete machine prolonged.

Embodiment
Describe below in conjunction with the preferred embodiment of accompanying drawing, should be appreciated that preferred embodiment described herein only is used for explanation and explains the utility model, and be not used in qualification the utility model the utility model.
Like Fig. 1, Fig. 2, shown in Figure 3, a kind of volute assembling type edge cover comprises retaining ring 1 and interior cover 2, and retaining ring 1 front end has radiating fin 3, cover 2 in the retaining ring inboard is connected with, and there is radiating fin 3 in the outside of interior cover 2; Radiating fin 3 on the retaining ring embeds volute; Retaining ring 1 is fixed on the volute 5 through bolt 4.
Retaining ring 1 processes with interior cover 2 integral body, is " protruding " font.
The radiating fin 3 in interior cover 2 outsides does not contact with volute 5.
Working clearance between volute assembling type edge cover and the turbine blade is 0.4mm～0.6mm.
The material of volute assembling type edge cover is Cr18NiTiAL, and more traditional volute material heat resistance is better.
Like Fig. 4, Fig. 5, shown in Figure 6, present embodiment and embodiment's 1 difference is: retaining ring 1 passes through draw-in groove 6 assembly units with interior cover 2, and for split type, interior cover 2 is fixed on volute 5 by retaining ring 1.
A kind of volute assembling type edge of the utility model cover adopts the special heat resisting corrosion-proof corrosion material that is different from volute to process, and can adapt to working environment more than 850 ℃; Reduce the heat transfer and the amount of deformation of volute, reduce the probability that turbine blade is wiped shell, reduce the working clearance of turbine blade and volute simultaneously; Improved the efficient of complete machine; Through bolts assemblies on volute, timely dismounting and change, thus prolonged working life of pressurized machine complete machine.
What should explain at last is: the above is merely the preferred embodiment of the utility model; Be not limited to the utility model; Although the utility model has been carried out detailed explanation with reference to previous embodiment; For a person skilled in the art, it still can be made amendment to the technological scheme that aforementioned each embodiment put down in writing, and perhaps part technical characteristics wherein is equal to replacement.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
