Abstract
The utility model discloses a turbocharger compressor impeller. The turbocharger compressor impeller comprises a wheel hub and blades which extend from the wheel hub and are uniformly distributed on the wheel hub, which is characterized in that: the wheel hub is in a rotational body shape, the rotational bus at least comprises one arc segment, at least one mounting part is arranged on one end of the wheel hub, the blade comprises a first blade edge near to the mounting part, a second blade edge far away from the mounting part, and a third blade edge arranged between the first blade edge and the second blade edge, and the third blade edge at least comprises one arc segment, and the arc angle of the arc segment is 90 degrees. The structure of the impeller is reasonable, and the profile loss is effectively reduced.
Description
Technical field
The utility model relates to turbocharging technology field, particularly a kind of turbo-charger blower impeller.
Background technique
Turbosupercharging is a kind of technology of utilizing internal-combustion engine (Internal Combustion Engine) to operate the exhaust gas driven air compressor (Air-compressor) producing.It,, to increase the air mass flow that enters internal-combustion engine, helps the more fuel of combustion in IC engine or makes fuel combustion more abundant, thereby improves working efficiency of internal combustion engine.
In turbosupercharger, the effect of compressor impeller is to absorb, utilize the waste gas of discharging in cylinder to make mechanical work by turbine, in order to improve the air pressure of supercharger air compressor outlet, by the rotation of compressor impeller, air intake is arrived to pressurized machine, by air compressing, thereby provide enough air to cylinder.The quality of judgement turbine blade, can measure by CASCADE EXPERIMENT.The general good compressor wheel blade pressure of effect along the back of the body arc of blade profile and inner arc by import to outlet gradually, reduce reposefully, and does not produce diffusion district, even if produce little diffusion district, needs even reduction yet, only appears near in outlet a bit of.The gradient of the pressure reduction streamwise of trailing edge place back of the body arc and inner arc is little.In existing turbo-charger blower impeller, the molded line loss level gap of reactionary style blade profile is very little.And traditional impulse blade profile, because blade is plump, deflection angle is large, profile loss is obvious.
Therefore, be necessary above-mentioned defect to improve.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of compressor impeller of internal combustion engine turbocharger, and it is rational in infrastructure, can effectively reduce profile loss.
For solving the problems of the technologies described above, the technological scheme that the utility model provides is: a kind of turbo-charger blower impeller, comprise wheel hub, and from described wheel hub, extend, be uniformly distributed in the blade described wheel hub; Wherein, described wheel hub is revolution shape, and its revolution bus at least comprises an arc section, and one end of described wheel hub is provided with at least one assembly department; Described blade comprises the first blade edge near described assembly department, the second blade edge away from described assembly department, and first the 3rd blade edge edge between blade edge and the second blade edge, described the 3rd blade edge at least comprises an arc section, the arc round angle of described arc section is 90
°
Further, described blade is all crooked in the other direction along turbine rotating photo.
Further, described wheel hub is also provided with a mounting hole, and described mounting hole is through hole.
Further, described assembly department is the boss above the end of described wheel hub.
The compressor impeller of the turbosupercharger that the utility model provides, well-designed owing to carrying out on blade wheel structure, be specifically provided with multistage face and curved edge, reduced pressure loss when air contacts with blade, improve gas compressor working efficiency.

Below in conjunction with drawings and Examples, the utility model is described in further detail, in accompanying drawing:
Fig. 1 is this turbo-charger blower impeller structural representation.
In figure, wheel hub-1; Assembly department-11; Mounting hole-12; Blade-2; The first blade edge-21; The second blade edge-22; The 3rd blade edge edge-23; Arc section-231.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with embodiment and accompanying drawing, further the utility model is described in detail:
In order to solve defect of the prior art, the utility model provides a kind of novel turbo-charger blower impeller, and it has reduced pressure loss when air contacts with blade, improves gas compressor working efficiency.
Fig. 1 is this turbo-charger blower impeller structural representation, and as shown in Figure 1, a kind of turbo-charger blower impeller, comprises wheel hub 1, from described wheel hub 1, extends, is uniformly distributed in the blade 2 described wheel hub 1; Described wheel hub 1 is revolution shape, and its revolution bus at least comprises an arc section, and one end of described wheel hub 1 is provided with at least one assembly department 11; Described blade 2 comprises the first blade edge 21 near described assembly department 11, the second blade edge 22 away from described assembly department, and first the 3rd blade edge edge 23 between blade edge 21 and the second blade edge 22, described the 3rd blade edge 23 at least comprises an arc section 231, and the arc round angle of described arc section 231 is 90 °
And described blade 2 is all crooked in the other direction along turbine rotating photo.Contrary direction along turbine rotation is crooked, the efficiency and the range of flow of having widened gas compressor of gas compressor have been increased, thereby can make engine efficiency improve, reduce fuel consume, improve the Economy of motor, raising along with supercharger impeller pressure ratio, use more and more thinner and excessive the leaning forward or palintrope of Leaf 2, easy excited vibrational under High Rotation Speed, when the frequency of excitation force and the natural frequency of blade 2 are quite or while becoming integral multiple, resonance occurs blade 2 will cause fatigue damage, have a strong impact on integrity and the reliability of turbosupercharger
Referring to Fig. 1, described wheel hub 1 is also provided with a mounting hole 12, and described mounting hole 12 is through hole.This mounting hole is used for installing coupling shaft or coupling.
Described assembly department 11 is the boss above the end of described wheel hub 1.
The compressor impeller of the turbosupercharger that the utility model provides, well-designed owing to carrying out on blade wheel structure, be specifically provided with multistage face and curved edge, reduced pressure loss when air contacts with blade, improve gas compressor working efficiency.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
