Abstract

The invention belongs to the technical field of engine turbocharging, and relates to a vortex end outlet structure with a core. The vortex end outlet structure with the core comprises a turbine shell, wherein a turbine capable of rotating around the axis of the turbine shell is arranged in an inner cavity of the turbine shell; a turbine shell outlet is formed in a shell body of the turbine shell; the core is arranged on the center position of the outlet of the turbine shell; a turbine shaft is integrated on the turbine; a gap is formed between the core and the turbine shaft; and the core is integrated on a transition joint or the turbine shell. The vortex end outlet structure with the core is simple and reasonable in structure, and is low in producing and manufacturing cost; and one core is additionally arranged on the center position of the vortex end outlet so that integral efficiency of the vortex end can be improved.

[0017] The specific embodiments of the present invention will be further described below in conjunction with the drawings.

[0018] Figure 1~3 Include the angle a formed by turbine 1, turbine shell 2, core 3, transition joint 4, turbine shaft 5, turbine shell outlet 6, core outer diameter wall profile and turbine shell outlet inner diameter wall profile on the plane passing through the turbine shell axis Wait.

[0019] Such as Figure 1~3 As shown, the present invention is a cored vortex end outlet structure, including a turbine shell 2, the inner cavity of the turbine shell 2 is provided with a turbine 1 that can rotate around the axis of the turbine shell, and the shell of the turbine shell 2 is provided with a turbine A core 3 is arranged at the center of the shell outlet 6 and the turbine shell outlet 6, a turbine shaft 5 is integrated on the turbine 1, a gap is left between the core 3 and the turbine shaft 5, and the core 3 is integrated on the transition joint 4 or the turbine shell 2.

[0020] The core 3 is arranged at the center of the outlet of the turbocharger vortex end.

[0021] The core 3 in the product of the present invention can have a variety of structural forms, and the following are generally used in practice: 1. The core 3 is cylindrical. 2. The core 3 has a conical shape, and the diameter of the end of the core 3 close to the turbine shaft 5 is smaller than the diameter of the end far away from the turbine shaft 5. 3. The core 3 includes a conical part and a cylindrical part that are integrally connected, wherein the conical part is close to one end of the turbine shaft 5, and the diameter of the conical part close to the turbine shaft 5 is smaller than the diameter of the end far away from the turbine shaft 5.

[0022] Such as image 3 As shown, the angle a formed by the outer diameter wall surface profile of the core 3 and the inner diameter wall surface profile of the turbine shell outlet 6 on a plane passing through the turbine shell axis is an acute angle.

[0023] The working principle of the present invention is: by adding a core at the center of the exit of the turbine shell, the wake area on the back of the turbine shaft is eliminated, thereby reducing the turbulence area at the exit of the vortex end, thereby improving the overall efficiency of the vortex end.

[0024] The above description is an explanation of the present invention, not a limitation of the present invention. For the scope of the present invention, please refer to the claims. Any form of modification can be made within the protection scope of the present invention.
