[0038] in figure 1 with figure 2 In which figure 1 It is a schematic diagram of the main sectional structure of the turbine before optimization, figure 2 It is a schematic diagram of the main sectional structure of the optimized turbine according to the present invention.
[0039] The powder injection molding supercharger turbine includes a hub 1 and an impeller 2 arranged at equal intervals (or unequal intervals) on the hub. The upper and lower ends of the hub are respectively provided with lower circular holes 4 and 4 coaxial with the hub. The upper round hole 5, the upper round hole and the lower round hole are blind holes with two inner ends spaced apart. The blind holes are preferably conical holes (equivalent to round holes with a draft angle). The bottom end of the hub An annular groove 3 is provided, and the annular groove is concentric with the hub shaft. The JP60 turbocharger for a vehicle is used as a specific embodiment (see Figure 4 ), the turbine inlet diameter ...
