Abstract
The utility model relates to an efficient gas compressor impeller, in particular to a gas compressor impeller on a turbocharger. The efficient gas compressor impeller comprises a wheel hub, wherein the wheel hub is shaped like a horn transiting in a streamline and arc mode from the axial direction to the radial direction, and vanes are evenly distributed outside the wheel hub. The efficient gas compressor impeller is characterized in that a flow guide groove is formed in the wheel hub between every two adjacent vanes, the flow guide grooves are distributed in the wheel hub in the streamline direction. By means of the gas compressor impeller, impact and friction among the gases are reduced, the temperature of the gases is lowered, and the efficiency of the impeller is improved. The efficient gas compressor impeller is suitable for being applied to a high-pressure-ratio and high-efficiency supercharger.
Description
Technical field
The utility model relates to a kind of turbosupercharger.Specifically, be the compressor impeller on the turbosupercharger, be particularly useful on high pressure ratio, the high efficiency pressurized machine.
Background technique
Make industry at internal-combustion engine and all know, pressurized machine is that internal-combustion engine is made second milestone on the history.Pressurized machine is as the important component part of internal-combustion engine, but its effect is the power of increasing combustion engine, reduces discharge of harmful gases, makes the discharging of internal-combustion engine reach international emission standard simultaneously, satisfies the purpose of environmental protection.
Present most popular pressurized machine is dumbbell shape, and it comprises turbine end, gas compressor end and intermediate three parts.Rotor is as the core, be support with the middle bearing bracket, bear the effect that important energy transmission transforms, engine exhaust gas does work by turbine end, the rotation of drive turbine shaft, the compressor impeller of rotation does work to fresh air together then, at last pressurized gas is transported in the cylinder, thereby increase power reduces pollutant emission.
Impeller wherein comprises wheel hub, described wheel hub contains wheel shaft, fixedly there is base plate the wheel shaft inner end, described base plate is circular, its plate face is vertical with wheel shaft, and it is excessive to be streamlined circular arc between the outer side surface of wheel shaft and the edge of base plate, make described wheel hub for from wheel shaft axially to base plate radially be excessive tubaeform of streamlined circular arc, wheel hub circumferentially be evenly equipped with spiral blade.The end that described spiral blade and base plate are adjacent is connected on the proximal surface of base plate, and a vertical limit and the described wheel shaft of described spiral blade form as one.Because the hub outside surface that above-mentioned impeller is is streamlined smooth surface, when impeller does work to air inlet, make gas to enter in the meridian passage of impeller at a high speed, because pressure and temp, the speed of gas are very inhomogeneous, and at the wall of blade and hub access adhesive quality is arranged simultaneously, in smooth meridian passage, gas is easy to generate turbulent flow and eddy current, can't flow according to desirable direction smoothly, produces collision, friction between gas, thereby improved gas temperature, reduced the efficient of impeller.
The model utility content
Problem to be solved in the utility model provides a kind of efficient compressor impeller.Adopt this compressor impeller, can reduce collision, friction between gas, reduce gas temperature, improve the efficient of impeller.
For addressing the above problem, the utility model is taked following technological scheme:
Efficient compressor impeller of the present utility model comprises wheel hub, described wheel hub is for from axially to radially being excessive tubaeform of streamlined circular arc, its outside is evenly equipped with blade, and being characterized in has guiding gutter on the wheel hub between adjacent blades, and described guiding gutter is uniform in wheel hub upper edge grain direction.
Wherein, described wheel hub contains wheel shaft, fixedly there is base plate the wheel shaft inner end, described base plate is circular, its plate face is vertical with wheel shaft, and it is excessive to be streamlined circular arc between the outer side surface of wheel shaft and the edge of base plate, makes described wheel hub for axially radially being excessive tubaeform of streamlined circular arc to base plate from wheel shaft.
Take such scheme, have the following advantages:
By such scheme as can be seen, because the wheel hub between adjacent blades is processed with guiding gutter, described guiding gutter is uniform in wheel hub upper edge grain direction.In the time of in gas enters adjacent two interlobate meridian passages, by the effect of guiding gutter, can eliminate turbulent flow and eddy current that gas produces, gas is flowed according to desirable direction smoothly, avoid collision and friction between gas, thereby reduce the gas temperature of knowing clearly, improved the efficient of impeller.
Description of drawings
Fig. 1 is efficient compressor impeller schematic representation of the present utility model;
Fig. 2 is the schematic top plan view of Fig. 1.
Embodiment
As depicted in figs. 1 and 2, efficient compressor impeller of the present utility model comprises wheel hub, and this wheel hub comprises wheel shaft 2, and fixedly there is base plate 4 wheel shaft 2 inner ends.Described base plate 4 is circular, and its plate face is vertical with wheel shaft, and the plate face of the outer side surface of wheel shaft 2 and base plate 4 is smooth surface, makes described wheel hub for radially being excessive tubaeform of streamlined circular arc from wheel shaft 2 axial to base plate 4.Wheel hub circumferentially be evenly equipped with blade 1, this blade is helical.Wheel hub 1 of adjacent vanes is processed with guiding gutter 3, and described guiding gutter 3 is evenly arranged in wheel hub upper edge grain direction.When gas enters in the meridian passage of 1 in adjacent two blades, by the effect of guiding gutter 3, can eliminate turbulent flow and eddy current that gas produces, gas is flowed according to desirable direction smoothly, avoid collision and friction between gas, thereby reduced the temperature of gas, improved the efficient of impeller.
Be processed with axial center hole on the described wheel shaft 2, described axial center hole 5 matches with main shaft under installment state, is furnished with locking nut on the overhanging end of main shaft.Described locking nut is the approximate circle tapered cup nut, and the top of this approximate circle tapered cup nut is closed shape.The outer side surface of described locking nut is the curved streamline transition to the bottom from its top.Like this, the natural wind that enters the impeller intake grill can make that the stream pressure size that enters the interior each point of impeller is more even along in the locking nut even well-regulated inflow impeller of arc streamiline surface all around, thereby has avoided distortion, the damage of spiral blade.
The efficient compressor impeller that the blade 1 that the wheel hub that is made of wheel shaft 2 and base plate 4 described in above-described embodiment, the wheel hub outside are uniform and the features such as guiding gutter 3 on 1 wheel hub of adjacent two blades constitute is to adopt the numerical control milling machine milling to form.
