Description
Technical field
The utility model relates to turbocharger of motor product technical field, particularly the sealing of a kind of turbosupercharger whirlpool end and collet position structure.
Background technique
Current in vehicular engine industry, turbosupercharger is more and more used, and more and more high request is more and more higher to the waste gas seal request of turbosupercharger for user, also will pursue little boundary dimension and reliability simultaneously.
Turbosupercharger collet is arranged on the turbine box whirlpool end of turbosupercharger and the binding site of bearing support; the effect of collet stops the high heat of the engine exhaust passed through in turbine box too much to conduct to the bearing support and the lubrication system that comprise High Rotation Speed component; the multiple vitals of protection pressurized machine, from the impact of excessive temperature, optimizes pressurized machine internal work environment.
Common turbosupercharger whirlpool end sealing and collet position structure have following two kinds:
One adopts pressing plate and screw location, this structure as shown in Figure 1, the structure of collet 3 as shown in Figure 2, collet 3 is fixed on turbine box 1 and the binding site of bearing support 2 by pressing plate 4 and screw 5, is pushed down the formation location, shirt rim of collet 3 by the flange plate end face of step end face and bearing support 2 in turbine box 1.The shirt rim that sealing dependence between turbine box 1 and bearing support 2 pushes down collet 3 by the end face of the flange plate 2-1 on step end face in turbine box 1 and bearing support 2 seals.
Also one adopts clip location, and this structure as shown in Figure 3, turbine box 1 is provided with flange plate 1-1, bearing support 2 is designed with flange plate 2-1.The structure of collet 6, as shown in accompanying drawing 4, accompanying drawing 5, is designed with the elastic tongue piece 6-1 protruding shirt rim Transverse plane in the shirt rim of collet 6.Collet 6 is arranged between the interior step end face of turbine box 1 and the end face of bearing support 2, clamps the flange plate 1-1 on the turbine box 1 and flange plate 2-1 on bearing support 2 it directly compressed by clip 7.Sealing between turbine box 1 and bearing support 2 relies on the flange end face of turbine box 1 and bearing support 2 to seal.
In homologous series product, collet 3 size adopting pressing plate 4 and screw 5 to locate is minimum, and collet 3 simple structure, high reliability, but this structure is owing to needing to arrange tapped hole on the end face of turbine box 1, therefore cause the contour structure size of turbine box 1 comparatively large, and location and installation is more complicated; Be exactly that sealing between turbine box 1 and bearing support 2 relies on the shirt rim pushing down collet 3 by the flange plate end face of step end face and bearing support 2 in turbine box 1 to seal in addition, sealing effect is bad.
Adopt clip 7 structure location, the sealing between turbine box 1 and bearing support 2 relies on the flange plate end face of turbine box 1 and bearing support 2 to seal, and sealing effect is better than the former.But the shirt rim due to collet 6 adopts elastic tongue piece 6-1 as limit structure, cause collet 6 size comparatively large, therefore cause the contour structure size of assembly also to increase, simultaneously higher to the designing requirement of elastic tongue piece 6-1, reliability is lower.
Summary of the invention
The purpose of this utility model be overcome prior art above-mentioned deficiency and the sealing of a kind of turbosupercharger whirlpool end and collet position structure are provided, on employing clip location sealing architecture basics, use the collet in pressing plate and screw position structure, utilize collet overall as an elastic element, rely on collet self-deformation to be fixed between turbine box and bearing support.
The technical solution of the utility model is: the sealing of a kind of turbosupercharger whirlpool end and collet position structure, turbine box and bearing support are provided with flange plate, clip is stuck on the flange plate on turbine box and the flange plate on bearing support, turbine box and bearing support are connected as a single entity by clip card, the junction plane of turbine box and bearing support adopts end face seal.Collet is arranged between the interior step end face of turbine box and the end face of bearing support, and the front-end face of bearing support withstands on the interior edge face of collet, makes collet produce distortion, and collet is fixed between turbine box and bearing support by the elastic force relying on himself distortion to produce.
The turbosupercharger whirlpool end sealing that the utility model provides and collet position structure adopt the yoke configurations that sealing is higher on the whole, on yoke configurations basis, use the collet structure simpler in pressing plate and bolt structure, reliability is higher.Utilize steel collet overall as an elastic element, be fixed between turbine box and bearing support by self-deformation.Whole collet is as elastic element, structure, be better than in the complicated elastic tongue piece structure of shirt rim design, size is less, manufacture is simple, cost is lower, simultaneously under identical axial deformation, integral, flexible element radial dimension is greater than the radial dimension of shirt rim elastic tongue piece, and the little reliability of deformation rate is higher; From material, the material of refractory steel can meet the needs of small deformation completely, and maintains original heat insulating function.Because collet size is less, the flange size of yoke configurations is adopted also and then to reduce.
The utility model compared with prior art has following features:
Adopt design proposal of the present utility model, effectively can improve turbosupercharger whirlpool end sealability, and improve reliability of structure, reduce boundary dimension, meet the demand of client to turbocharger products.
Below in conjunction with the drawings and specific embodiments, detailed construction of the present utility model is further described.
