Abstract
The invention discloses a turbocharger heat insulation structure which comprises a turbine box and a bearing box, wherein the turbine end of the bearing body is jointly connected with the turbine box in a step-structure mode, a circulating cooling water cavity is arranged at the inner end side, close to the turbine, of the bearing body, a water inlet and a water outlet which penetrate through the circulating cooling water cavity are arranged on the bearing body, and the bearing body and the water cavity are cast and molded by using the same material. According to the invention, an insulation sleeve structure can be omitted, a joint type contact seal can be designed between the bearing body and the turbine box and the joint position can be designed with a step section so as to reach the sealing effect; the water cavity arranged at the inner end part, close to the turbine, of the bearing body can be used for achieving the heat insulation effect; and the bearing body and the water cavity are cast and molded by using the same material, so that the deformation difference between the bearing body and the water cavity can be lessened. Compared with the prior art, the turbocharger heat insulation structure provided by the invention has the advantages that the management cost of parts can be lowered because insulation sleeve parts and dies are not required; and meanwhile, the part assembly amount can be reduced and the transferred assembly efficiency can be improved, thus the turbocharger heat insulation structure is suitable for popularization.
Description
Technical field:
The present invention relates to the turbo-charger technical field of internal-combustion engine, particularly a kind of turbosupercharger heat-insulating structure.
Background technique:
Turbosupercharger is that the high temperature, the high pressure exhaust gas that utilize motor to discharge drive turbine work; For preventing that heat from reaching bearing and gas compressor end from turbine end; Thereby influence the reliability and reduction compressor efficiency of bearing working; Referring to Fig. 1, in bearing support 1 and turbine box 2 joints collet 3 can be set, reduce thermal radiation.
Adopt the collet structure can bring following deficiency: 1, to increase number of spare parts and mould input, increase cost; 2, increase part assembling quantity, lower efficiency; 3, increase the part management expense.
Summary of the invention
Technical problem to be solved by this invention is the deficiency to existing technology, and a kind of turbosupercharger heat-insulating structure is provided, and this heat-insulating structure need not increase collet; Through the binding type contact seal of bearing support and turbine box, and, water cavity is set simultaneously in bearing support in joint place design ladder section; When reaching sealing gland, reduce thermal radiation; Both can effectively reduce number of spare parts, reduce the cost, improve efficiency of assembling again.
Technical problem to be solved by this invention can realize through following technological scheme:
A kind of turbosupercharger heat-insulating structure; Comprise turbine box and bearing support; It is characterized in that; The turbine end of said bearing support and said turbine box are fitted and connected through the hierarchic structure form, in said bearing support, be provided with the recirculated cooling water chamber and the entery and delivery port that connects with said recirculated cooling water chamber is installed on said bearing support near turbine is distolateral.
Said bearing support and water cavity adopt the same material cast molding.
The present invention has cancelled the collet structure; Bearing support is designed to and the contact seal of turbine box binding type; And, reach the effect of sealing, and reach effect of heat insulation through near the turbine end position water cavity being set in bearing support inside in joint place design ladder section; Bearing support and water cavity adopt the same material cast molding, less modified difference between the two.
Patent of the present invention does not compared with prior art need the input of collet part and mould, reduces the part management expense, reduces part assembling quantity simultaneously, improves to change and joins efficient, the suitable popularization.
Description of drawings:
Fig. 1 is the structural representation of existing turbosupercharger.
Fig. 2 is the structural representation of turbosupercharger of the present invention.
Fig. 3 is a bearing support structural representation of the present invention.
Embodiment:
For technological means, creation characteristic that the present invention is realized, reach purpose and effect and be easy to understand and understand, below in conjunction with concrete diagram, further set forth the present invention.
Referring to Fig. 2 and Fig. 3, the turbosupercharger heat-insulating structure shown in the figure comprises turbine box 10 and bearing support 20, and both adopt the same material cast molding.
Stepped construction 11 is processed in this side end face in that turbine box 10 is connected with bearing support 20; The end face of bearing support 20 turbine end also is arranged to stepped construction 21; Stepped construction 11 and stepped construction 21 mutual interlocks, the turbine end of bearing support 20 and turbine box 10 are fitted and connected through the hierarchic structure form like this.Thereby prevent that effectively high-temperature gas from scurrying to the end of calming the anger; Increase recirculated cooling water chamber 22 in bearing support 20 inside near the turbine end position simultaneously; Adopt the same material cast molding; And the entery and delivery port (not shown) that connects with recirculated cooling water chamber 22 is installed on bearing support 20, through the circuit cooling water with the high-temperature gas of cooling from the whirlpool end.
More than show and described basic principle of the present invention and major character and advantage of the present invention.The technician of the industry should understand; The present invention is not restricted to the described embodiments; That describes in the foregoing description and the specification just explains principle of the present invention; Under the prerequisite that does not break away from spirit and scope of the invention, the present invention also has various changes and modifications, and these variations and improvement all fall in the scope of the invention that requires protection.The present invention requires protection domain to be defined by appending claims and equivalent thereof.
