Widely used small sized turbocharger is radial turbine at home at present, and turbine air inlet face and the face of giving vent to anger are 90 degree, and windage loss is more, has a strong impact on the efficient of small sized turbocharger; Behind the coupling motor, the power character of its motor, Economy, environment protection emission level all lag behind abroad.
And the lubricating oil temperature of motor own is high at present, and the effect of oil lubrication pressurized machine bearing reduces, and can not satisfy the functional reliability requirement of motor, makes bearing wear serious, and turbocharger fails causes whole motor cisco unity malfunction.
The model utility content
The utility model purpose is to provide a kind of small-sized mixed turbo with the water cooled bearing body, to solve existing technical problem.
For achieving the above object, according to an aspect of the present utility model, a kind of small-sized mixed turbo with the water cooled bearing body is provided, comprise: turbine shaft, be installed in the turbine outer end of turbine shaft turbine case, be installed in compressor impeller on the turbine shaft, be sleeved on the compressor housings of compressor impeller outer end and be installed in turbine case and compressor housings between intermediate, the air outlet that turbine case is provided with suction port and communicates with suction port, turbine case is the mixed-flow housing of variable cross section, and suction port is vortex patern.
Further, compressor housings adopts die cast.
Further, bearing support is installed also between turbine shaft and the intermediate, bearing support is oil cooling and water cooled bearing body.
The utlity model has following beneficial effect:
1, turbine case of the present utility model is the mixed-flow housing of variable cross section, and suction port is vortex patern, has reduced the loss ratio of gas, has improved the working efficiency of availability and the turbine of gas;
2, bearing support adopts the water cooled bearing body, has guaranteed the normal operation of lubricated oil performance and bearing arrangement, improves the working life of turbosupercharger;
3, compressor housings adopts die cast, improves the working efficiency of gas compressor.
Except purpose described above, feature and advantage, the utility model also has other purpose, feature and advantage.The below is described in further detail the utility model with reference to figure.
Description of drawings
The accompanying drawing that consists of the application's a part is used to provide further understanding of the present utility model, and illustrative examples of the present utility model and explanation thereof are used for explaining the utility model, do not consist of improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the cross-sectional schematic of small-sized mixed turbo of the water cooled bearing body of the utility model preferred embodiment;
Fig. 2 is that the master of the turbine case of the utility model preferred embodiment looks schematic representation; And
Fig. 3 is schematic side view shown in Figure 2.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
Referring to Fig. 1, preferred embodiment of the present utility model provides a kind of small-sized mixed turbo with the water cooled bearing body, turbine shaft 10, be installed in the turbine outer end of turbine shaft 10 turbine case 20, be installed in compressor impeller 30 on the turbine shaft 10, be sleeved on the compressor housings 40 of compressor impeller 30 outer ends and be installed in turbine case 20 and compressor housings 40 between intermediate 50, the air outlet 22 that turbine case 20 is provided with suction port 21 and communicates with suction port 21, turbine case 20 is the mixed-flow housing of variable cross section, and suction port 21 is vortex patern.
Please in conjunction with referring to Fig. 2 and Fig. 3, turbine case 20 comprises suction port 21 and the air outlet 22 that communicates with suction port 21, turbine case 20 is for having the housing of mixed-flow structure, its inner chamber is the passage of variable cross section, the suction port 21 of turbine case 20 is vortex patern, so that air-flow flows to the air outlet 22 of turbine case 20 sideling from the suction port of turbine case 20, so that the loss of gas is little, improve the availability of gas and the working efficiency of turbine.
Between turbine shaft 10 and the intermediate 50 bearing support 60 is installed also, bearing support 60 is for having the water cooled bearing body of water-cooling structure.Bearing support 60 has water cavity passage and oil leab.The water cavity passage has the cooling water that attracts from water cooling system of engine, this cooling water produces pressure through engine water pump, make it center on oil leab and turbine shaft 10 channel flow, take away the heat of lubricant oil and the heat that turbine wheel end high-temp waste gas is come through bearing support 60 conduction; And also drive the heat that the friction of each part produces, and so that bearing arrangement remains on quite low temperature, avoid bearing support 60 overheated and damage, guarantee the normal operation of lubricated oil performance and bearing arrangement, improve the working life of turbosupercharger.
Preferably, compressor housings 40 adopts die cast, with the degree of finish on raising compressor housings 40 inner flow passage surfaces, thus the working efficiency of raising gas compressor.
As can be seen from the above description, preferred embodiment of the present utility model has following beneficial effect:
Turbine case of the present utility model is the mixed-flow housing of variable cross section, and suction port is vortex patern, has reduced the loss ratio of gas, has improved the working efficiency of availability and the turbine of gas; Bearing support adopts the water cooled bearing body, has guaranteed the normal operation of lubricated oil performance and bearing arrangement, improves the working life of turbosupercharger; Compressor housings adopts die cast, improves the working efficiency of gas compressor.
The above is preferred embodiment of the present utility model only, is not limited to the utility model, and for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
