Description
Technical field
The utility model belongs to automotive fittings accessory field, relates to a kind of cast inblock composition metal turbine case.
Background technique
Volute is the important composition parts of pressurized machine, and it can by the high temperature and high pressure gas of motor discharge equably water conservancy diversion to the nozzle and turbine blade of whole circle.Tradition volute, not containing structure of mosaic, adopts a kind of material, without heat-insulating structure, can only adapt to the operating temperature of less than 700 DEG C.For above-mentioned Problems existing, also develop some at present with bushing volute, Chinese patent 2011203488061 discloses a kind of volute assembling type embedded sleeve, and the volute of this kind of specifications and models can adapt to higher temperature, and overall efficiency obtains and improves.In use find that the volute of this structure also exists some problems, mainly volute and bushing between employing activity assembly connection, rate of expanding with heat and contract with cold between the two is inconsistent, in use easily loosen, cause reliability low, and assembly cost between two parts is higher, increase enterprise's cost of production.
Summary of the invention
The utility model, for the problems referred to above, provides a kind of cast inblock composition metal turbine case, adopts this turbine case to improve functional reliability, reduces enterprise's cost of production.
According to the technical solution of the utility model: a kind of cast inblock composition metal turbine case, is characterized in that: comprise volute body and volute is bushing, described volute body inner chamber forms bushing fixed hole, and volute is bushing to be flush-mounted in bushing fixed hole.
As further improvement of the utility model, the hole wall of described bushing fixed hole forms the tapered portion, projection, fixed groove, the through-hole section that connect in turn, bushing retaining ring, the inner sleeve comprising one and connect of shell, described inner sleeve circumferential surface is provided with spacing ring flat-plate, retaining ring is equipped with in described tapered portion place, limited ring board is located in fixed groove, and projection is arranged in the cell body that formed between spacing ring flat-plate and retaining ring surface; Inner sleeve outer end is stretched out from through-hole section.
As further improvement of the utility model, the outer end that described volute body inner chamber corresponds to bushing fixed hole forms cavity.
As further improvement of the utility model, described volute body and volute bushing between processed by casting.
Technique effect of the present utility model is: the utility model product structure is simple, reasonable in design, by adopting forging type to be fixedly connected with two parts, can prevent volute from bushingly to produce axially relative to volute, radial direction rocks, effectively improve functional reliability, reduce enterprise's cost of production.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is further described.
In Fig. 1, comprise that volute body 1, volute are bushing 2, retaining ring 2-1, inner sleeve 2-2, spacing ring flat-plate 2-3, bushing fixed hole 3, tapered portion 3-1, protruding 3-2, fixed groove 3-3, through-hole section 3-4, cavity 4 etc.
As shown in Figure 1, the utility model is a kind of cast inblock composition metal turbine case, comprises volute body 1 and volute bushing 2, and described volute body 1 inner chamber forms bushing fixed hole 3, and volute bushing 2 is flush-mounted in bushing fixed hole 3.
The hole wall of described bushing fixed hole 3 forms the tapered portion 3-1 connected in turn, protruding 3-2, fixed groove 3-3, through-hole section 3-4, shell bushing 2 comprises retaining ring 2-1, the inner sleeve 2-2 that one connects, described inner sleeve 2-2 circumferential surface is provided with spacing ring flat-plate 2-3, retaining ring 2-1 is equipped with in described tapered portion 3-1 place, spacing ring flat-plate 2-3 is arranged in fixed groove 3-3, and protruding 3-2 is arranged in the cell body that formed between spacing ring flat-plate 2-3 and retaining ring 2-1 surface; Inner sleeve 2-2 stretches out outer end from through-hole section 3-4.
The outer end that described volute body 1 inner chamber corresponds to bushing fixed hole 3 forms cavity 4.
Processed by casting between described volute body 1 and volute bushing 2.
Spacing ring flat-plate 2-3 on volute in this product bushing 2 is conical surface near retaining ring 2-1 side, and the outer surface of retaining ring 2-1 is conical surface, and this conical surface outer diameter is less than inner diameter, and the shape of this conical surface and tapered portion 3-1 matches.The shape of spacing ring flat-plate 2-3 and the shape of fixed groove 3-3 match.
The utility model product carries out technological improvement to existing " volute assembling type embedded sleeve ", by adopting the mode of integral cast to connect volute body 1, both volutes bushing 2, effectively can improve global reliability, reduces cost of production; Due to cast inblock be integrated can effectively avoid existing product because of the rate of expanding with heat and contract with cold different, cause the problem easily loosened.This product can tolerate higher temperature, and Product Precision is higher simultaneously.
