Abstract
The utility model discloses a turbocharger which comprises a turbine rotor, a heat insulating sleeve, a turbine casing and a sealing ring, wherein the part of a wheel back of the turbine rotor is provided with a circular ring-shaped boss, and the heat insulating sleeve is provided with a circular ring-shaped groove in the position corresponding to the circular ring-shaped boss so that the circular ring-shaped boss on the wheel back of the turbine rotor conveniently extends into the circular ring-shaped groove on the heat insulating sleeve; certain gaps are arranged among the upper and the lower side faces and the inner and the outer circular faces of the circular ring-shaped boss and the circular ring-shaped groove so that the circular ring-shaped boss and the circular ring-shaped groove conveniently make corresponding rotary movement. Consequently, a labyrinth type mechanical sealing structure is added on an exhaust passage between the turbine rotor and the heat insulating sleeve. The structure lightens the influence on the sealing ring on the wheel back of the turbine rotor caused by exhaust gases of the engine, improves the working environment of the sealing ring of the turbocharger, extends the service life of the sealing ring, improves the sealing performance of the turbocharger and reduces the failure rate of the turbocharger.
Description
Technical field
The utility model relates to a kind of turbosupercharger, relates in particular to a kind of turbosupercharger of high sealing performance.
Background technique
At present, between the turbine rotor wheel back of turbosupercharger and the collet direct access, in the course of the work, the waste gas that motor is discharged can directly be passed on the seal ring of turbine end.Sulphur contained in the waste gas has corrosive action to seal ring, and the high temperature of waste gas can make seal ring produce fatigue at high temperature, and the soot in the waste gas also forms carbon distribution easily at the seal ring position simultaneously, and these are the main causes that cause seal ring to lose efficacy.In the turbosupercharger of using at present, the failure rate of turbine end seal ring is much higher than the failure rate of gas compressor end seal ring, and it is the major reason of turbocharger fails that the inefficacy of turbine end sealing configuration causes turbocharger fails.
Summary of the invention
In order to solve the problem of above-mentioned existence, the utility model provides a kind of turbosupercharger of simple in structure, good sealing effect.
The technical solution of the utility model is to realize like this, a kind of turbosupercharger, comprise turbine rotor, collet, turbine case and seal ring are formed, wherein round ring boss is set at the turbine rotor wheel back, with the corresponding position of round ring boss toroidal cavity is set at collet, so that the round ring boss that turbine is taken turns back extend on the collet in the toroidal cavity, round ring boss and toroidal cavity between the side and between the inside and outside disc certain clearance is arranged up and down so that both relative rotary motion, thereby on the exhaust steam passage between turbine rotor and the collet, increase mechanical seal structure like the labyrinth.
Further, can be in turbine rotor turbine wheel back round ring boss quantity that is provided with and the toroidal cavity quantity that is provided with at the corresponding position of collet for a pair of, more than two pairs or two pairs.
Further, the side up and down of the side up and down of the round ring boss that turbine rotor turbine wheel back is provided with and the twice toroidal cavity of collet can be the plane, also can be curved surface.
Further, the cylindrical profile of the round ring boss that turbine rotor turbine wheel back is provided with and the twice toroidal cavity of collet interior round can be cylndrical surface, conical surface or curved surface.
Compared with prior art the beneficial effects of the utility model are: owing to increased a mazy mechanical seal structure on the exhaust steam passage between turbine rotor and the collet, thereby alleviate engine exhaust to influence between the turbine rotor back seal ring, improve the working environment of Sealing Ring of Turbocharger, improve the working life of seal ring, improve the sealability of turbosupercharger, reduce the rate of fault of turbosupercharger.

Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail, be illustrated in figure 1 as existing turbosupercharger, wherein form a parallel plane passage between turbine rotor 1 and the collet 2 with certain width, 3 waste gas can directly flow to the root of turbine rotor 1 from the engine emission to the turbine case, flow to seal ring 4 positions then, between the corrosive materials such as sulphur that contain in the waste gas seal ring is produced corrosive action like this, reduce the working life of seal ring.
Turbosupercharger of the present utility model as shown in Figure 2, comprise turbine rotor 1, collet 2, turbine case 3 and seal ring 4, wherein take turns back round ring boss 5 is set at turbine rotor 1, with the corresponding position of round ring boss toroidal cavity 6 is set at collet, so that the round ring boss 5 that turbine is taken turns back extend on the collet in the toroidal cavity 6, round ring boss 5 and toroidal cavity 6 certain clearance is arranged so that both relative rotary motion between the side and between the inside and outside disc up and down, thereby on the exhaust steam passage between turbine rotor 1 and the collet 2, increase a mazy mechanical seal structure, thereby alleviate the direct influence of engine exhaust, the working life of having improved seal ring to seal ring 4.In order to be applicable to the needs of different model different brands, the quantity of the groove that the corresponding position with collet of the boss quantity of turbine rotor wheel back is provided with can be decided as required, can be 1,2,3 are not waited, and taking turns the quantity that back is provided with round ring boss 5 at the turbine rotor 1 of as shown in Figure 2 turbosupercharger is 2.For the side up and down of the twice toroidal cavity 6 of the side up and down that reaches the round ring boss 5 that different effect turbine rotor 1 turbine wheel backs is provided with and collet 2, can be the plane simultaneously, also can be curved surface.The cylindrical profile of the round ring boss 5 that turbine rotor 1 turbine wheel back is provided with and the twice toroidal cavity 6 of collet 2 interior round can be cylndrical surface, conical surface or curved surface.
