Background technique
Along with increasing rapidly of world car recoverable amount, the worsening shortages of the energy, the going from bad to worse of environment, the energy-saving and emission-reduction of automobile industry have become the focus that All Around The World is paid close attention to.
turbosupercharger is installed, it is a new way of automobile industry energy-saving and emission-reduction in recent years, the air outlet of motor connect turbosupercharger the whirlpool end, motor exhaust blows the turbine of turbosupercharger, turbine drives the compressor impeller rotation by coupling shaft, the extraneous fresh air of compression in the process of compressor impeller rotation, the pressure side air outlet of pressurized machine is connected on the suction port of motor, after the fresh air of high pressure enters cylinder, because its pressure is high, oxygen content is many, thereby the burning meeting of fuel oil is more abundant, energy is able to abundant release, therefore in tail gas, harmful gas can reduce, and the power of motor can be stronger.
More valuable is the energy that turbosupercharger is closely utilized the waste gas of motor own, and the effective power of consumption of engine can not finished the work.
Because having motor exhaust, turbosupercharger drives, when engine speed is low, the tail gas quantity not sufficient is so that turbosupercharger reaches effective rotating speed, so therefore the efficient when car does not reach the turbosupercharger normal operation when just starting have hesitation.For alleviating this problem, developed again in recent years nozzle ring capable of changing cross sections.Nozzle ring is arranged in the volute of turbosupercharger, and its blade ring is around the surrounding of turbine, and another point connects bleed valve, variation along with the Worm gear pressurizing unit scroll internal pressure, bleed valve can be regulated the angle of nozzle blade, thereby controls air inflow, makes the rotating speed of turbine be in controlled the optimum state.
There is following several problem in nozzle ring in the past:
1. because at present increasing petrol engine has been installed turbosupercharger, cause turbo charger speed very high, the temperature of volute can reach 700 ?800 ℃, usually the volute material is gray iron or magnesium iron, the heat erosion meeting of meeting volute is very fast like this, and then causes volute to scrap very soon;
2. in the past the shifting fork disc of nozzle ring can be enclosed within on three rollers, works under the environment due to the tangible high-temp waste gas of nozzle ring, and roller is stuck sometimes, causes the nozzle ring cisco unity malfunction;
3. the shifting fork disc of nozzle ring is what to separate with blade and shift fork in the past, to such an extent as to will adjust the position of shift fork and shifting fork disc when changing nozzle ring, has increased labor intensity, has reduced efficient;
4. in the past nozzle blade is that an end has axle to be arranged in mounting disc, is to guarantee normal rotation, and the gap of blade rotor and mounting disc can be very large, easily too much carbon distribution and stuck.

Embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
See also Fig. 1, the utility model comprises mounting disc 6, shifting fork disc 5 and a plurality of blade and shift fork 7.Blade and shift fork 7 comprise the rotating shaft that is positioned at the middle part and be positioned at blade and the shift fork at two ends, rotating shaft be arranged in be opened on mounting disc 6 disk bodies, along circumferential equal angles axis hole spaced apart.Shifting fork disc 5 is located at mounting disc 6 backs, and edge is provided with the notch that equates with blade and shift fork 7 quantity within it, and the end of shift fork is arranged in notch.
In this example, be provided with the flange of projection vertically at the edge at mounting disc 6 backs, shifting fork disc 5 tops are located on this flange.Also be included in the trim ring 2 that outer rim is provided with a plurality of presser feets 1, the circle body of trim ring 2 between mounting disc 6 and shift fork and the installation screw 4 by 120 °, three circumferential intervals be fixed on the disk body of mounting disc 6 flange inner.
The inner edge that presser feet 1 is pushed down shifting fork disc 5 is fixed, and a plurality of presser feets distribute to provide uniform pressure in the first-class angle intervals of trim ring 2.Preferably, be provided with the bar hole that quantity is identical, the position is corresponding with presser feet 1 on the disk body of shifting fork disc 5, fall into to promote the stability of pressing for this presser feet 1.
By above-mentioned design, shifting fork disc 5 and mounting disc 6 and a plurality of blade and shift fork 7 are completed when dispatching from the factory and are installed and pass through debugging, and its performance and precision are met the requirements, and need not remake debugging when on pressurized machine, this nozzle ring being installed, can directly install, it is more convenient to operate.
To the impact of supercharger volute, the working life of improving volute, also comprise insulation cover 8 for effectively isolated high-temperature tail gas in this example.The following setting of concrete structure:
Insulation cover 8 is located at mounting disc 6 fronts, and the spacing column 9 that also is provided with 120 °, three circumferential intervals between mounting disc 6 and insulation cover 8 is spaced apart with both, and blade namely is arranged in space between the two.Spacing column 9 one ends are threaded connection and are fixed in mounting disc 6, and the other end is provided with bearing pin and is inserted in the axis hole that is opened in advance on insulation cover 8.
Also be provided with outward extending gas port vertically on insulation cover 8, be used for and pressurized machine between carry out airflow.
In this example, blade and shift fork 7 adopt the twin shaft design, namely also are provided with the bearing pin coaxial with the rotating shaft of blade and shift fork 7 on blade, and this bearing pin is arranged in the axis hole that is opened on insulation cover 8.Like this, by blade and shift fork 7 are erected on mounting disc 6 and insulation cover 8 simultaneously, it is more stably rotated.Therefore, the gap of the opinion of rotating shaft and axis hole can greatly reduce, and 0.06mm gets final product, and is not easy like this to produce the situation that carbon distribution stockpiles, and a small amount of carbon distribution also can become oiling agent, ensures the normal operation of whole nozzle ring.
Installation method: volute installation screw 3 passes the mounting hole on trim ring 2, shifting fork disc 5, mounting disc 6 and insulation cover 8 successively, and twist in the interior threaded hole that is located on Worm gear pressurizing unit scroll the end, realizes the fixing of nozzle ring integral body.
Improved nozzle ring goes slick, reliable and stable, life-span improves more than 20%, effectively protected Worm gear pressurizing unit scroll, improved the working life of pressurized machine simultaneously.This nozzle ring also facilitates installation and maintenance, has reduced client's labor intensity, has improved efficiency.
