Abstract
The invention discloses a turbocharger turbine with an internal-double-offset-ring petal-shaped head. The turbocharger turbine is precisely cast and molded through demolding, turbine blades are arranged on a hub, a centering cone face is arranged at the front portion of the hub, the internal-double-offset-ring petal-shaped head is arranged on the end face of the centering cone face, a positioning cylindrical pin is arranged on the end face of the bottom of the internal-double-offset-ring petal-shaped head, a semi-spherical top hole is formed in the end face of the positioning cylindrical pin, and the hub, the blades, the centering cone face, the internal-double-offset-ring petal-shaped head, the positioning cylindrical pin and the semi-spherical top hole are located on one axis. The axial length of the internal-double-offset-ring petal-shaped head is smaller than that of the centering cone face so that reduction of the strength of the whole turbine can be avoided; the axial length of the positioning cylindrical pin is a half of the axial length of the centering cone face so that later machining and assembling of the turbine can be convenient.
Description
Technical field
The present invention relates to turbo-charger technical field, be not a kind of turbocharger turbine.
Background technology
Turbine is the critical component of turbocharger, it works under the conditions of the bad working environments such as high temperature, high speed, this meaning to have stronger high temperature durability strength degree, good antifatigue and creep-resistant property, good high temperature microstructure stability, it is harsh to material requirements, so the turbine material price in turbocharger is high.Existing turbocharger turbine is as shown in Figure 1, turbine it is provided with by blade 2 on wheel hub 1, wheel hub 1 leading section is provided with the centering conical surface 3, the centering conical surface 3 leading section is provided with plum blossom lobe head 4, plum blossom lobe head 4 leading section is provided with hemispherical apical pore 5, at wheel hub 1, blade 2, the centering conical surface 3, plum blossom lobe head 4 and hemispherical apical pore 5 on the same axis.The centering conical surface 3 location when turbine welds with armature spindle, plum blossom lobe head 4 adds and location during assembling for machine.
Its defect of existing turbocharger turbine is: the centering conical surface 3 and the plum blossom lobe head 4 being respectively provided with on the axial length of turbine front end makes that the turbine length of turbocharger is longer, use material is more, relatively costly；On the other hand add the rotary inertia of turbocharger, weaken turbocharger transient response.
Chinese patent 101000011A discloses a kind of structure of turbine blade wheel weight reducing for pressurizer.This turbine by being respectively provided with interior six sides, lightening hole and friction welding (FW) heap hole in turbine hub end, so can alleviate turbine type mass, but lightening hole has goed deep into, with friction welding (FW) heap hole, the hub interior that turbo blade is fixedly linked, reduce turbine intensity, the turbine worked under high temperature, high pressure and the bad working environments such as high speed is ruptured and flies broken risk and be greatly increased, and interior six sides are when clamping, workpiece rotational angle is big, inefficient.
Summary of the invention
It is an object of the invention to overcome the above-mentioned deficiency of prior art and provide and a kind of reduce axial turbine length and quality, reduce cost, improve the turbocharger turbine of booster transient response characteristic.
The technical scheme is that the turbocharger turbine of the interior plum blossom lobe head of band, it is molded by demoulding hot investment casting, turbine it is provided with by blade on wheel hub, hub nose portion is provided with the centering conical surface, the end face of the centering conical surface is provided with interior plum blossom lobe head, the bottom end face of interior plum blossom lobe head is provided with setting circle pin, and the end face of setting circle pin is provided with hemispherical apical pore, and wheel hub, blade, the centering conical surface, interior plum blossom lobe head, setting circle pin and hemispherical apical pore are on same axis.
The axial length of interior plum blossom lobe head is less than the axial length of the centering conical surface, to avoid the weakening to turbine bulk strength；The axial length of setting circle pin is the half of centering cone face axial length, in order to turbine later stage machine adds and assembling.
The present invention compared with prior art has a characteristic that
The present invention is by arranging interior plum blossom lobe head, interior straight pin, hemispherical apical pore at the end face of the turbine centering conical surface, decrease the axial component of the plum blossom lobe head in prior art turbine and remove centering portion of material within the conical surface, shorten axial turbine length, alleviate turbine type mass, decrease the rotary inertia of booster, enhance turbocharger transient response, decrease turbine material usage amount simultaneously, effectively reduce turbine cost.
Below in conjunction with the drawings and specific embodiments, the detailed construction of the present invention is further described.

Accompanying drawing 1 is existing turbocharger turbine structural representation；
The turbocharger turbine structural representation of the interior plum blossom lobe head of band that accompanying drawing 2 provides for the present invention；
Accompanying drawing 3 is the right view of accompanying drawing 2.
Detailed description of the invention
The turbocharger turbine of plum blossom lobe head in band, it is molded by demoulding hot investment casting, turbine it is provided with by blade 2 on wheel hub 1, wheel hub 1 leading section is provided with the centering conical surface 3, the end face of the centering conical surface 3 is provided with interior plum blossom lobe head 7, the bottom end face of interior plum blossom lobe head 7 is provided with setting circle pin 6, and the end face of setting circle pin 6 is provided with hemispherical apical pore 5, at wheel hub 1, blade 2, the centering conical surface 3, interior plum blossom lobe head 7, setting circle pin 6 and hemispherical apical pore 5 on the same axis.
The axial length of interior plum blossom lobe head 7 is less than the axial length of the centering conical surface 3, to avoid the weakening to turbine bulk strength；The axial length of setting circle pin 6 is the half of the centering conical surface 3 axial length, in order to turbine later stage machine adds and assembling.
