Description
Technical field
The utility model relates to a kind of engine variable guide vane wheel, more precisely a kind of exhaust gas turbocharge engine variable guide vane wheel.
Background technique
The waste gas of what motor was discharged by exhaust gas turbocharge have certain energy introduces turbine and expansion work, whole power of exhaust gas turbine, for driving the gas compressor running wheel with turbo machine coaxial rotating, send into cylinder again by after compresses fresh air in gas compressor.This technology as improving engine power, the important measures that improve Economy and emission performance are used widely.Conventional exhaust turbosupercharging has problems: during low engine speed, the little and energy shortage of extraction flow, and the low pressurized effect of gas compressor that causes of secondary speed is not obvious; When engine operating condition changes, the inertia of turbosupercharger self makes its transient response characteristic poor, and when making acceleration, emission performance and economic performance are deteriorated.
Model utility content
The purpose of this utility model is to provide a kind of exhaust gas turbocharge engine variable guide vane wheel, can solve the above problems.
The utility model for achieving the above object, is achieved through the following technical solutions:
Exhaust gas turbocharge engine variable guide vane wheel, comprise nozzle ring, the side of nozzle ring arranges rotating ring, the side week of nozzle ring installs several connecting rod, adjustable vane is installed in one end of connecting rod, the other end fixing rotating panel of connecting rod, the side of swivel plate is connected with connecting rod, the opposite side of swivel plate installs cylindricality block, cylindricality block is cylindrical, and rotating ring is offered several driven rocking arm groove, driven rocking arm groove is circular arc, each driven rocking arm groove coordinates with a cylindricality block, and cylindricality block can rotate in driven rocking arm groove.
In order to realize the purpose of this utility model further, can also by the following technical solutions: the side week of described rotating ring arranges several projection, and each projection is positioned at a driven rocking arm groove side.
The utility model has the advantage of:
1, the utility model proposes the design proposal of the adjustable vane nonuniform mutation operator adopting nozzle ring in variable nozzle turbocharger, along the circumferential direction size is unequal mutually for the initial settling angle degree of each adjustable vane, its setting angle and adjustable vane inlet air flow angle are adapted, to meet the needs of turbo machine efficiency operation.
2, on this basis, the utility model proposes the design proposal that a kind of structure optimization based on driving ring realizes the change of variable nozzle turbocharger adjustable vane initial settling angle degree.
3, the utility model is without the need to processing and fabricating adjustable vane controlling mechanism installation mold again, and manufacturing process is simple, and processing cost is low, and the process-cycle is short.
4, the utility model rotating ring can rotate, and rotating ring drives adjustable vane to rotate by driven rocking arm groove with coordinating of cylindricality block, realizes the angle adjustment of adjustable vane.
5, the utility model also has advantage compact, cheap for manufacturing cost and easy to use simple for structure.
Accompanying drawing explanation
Accompanying drawing is used to provide further understanding of the present utility model, and forms a part for specification, is used from explanation the utility model, does not form restriction of the present utility model with embodiment one of the present utility model.In the accompanying drawings:
Fig. 1 is main TV structure schematic diagram of the present utility model; Fig. 2 is right TV structure schematic diagram of the present utility model.
Mark parts: 1 adjustable vane 2 driven rocking arm groove 3 cylindricality block 4 swivel plate 5 connecting rod 6 nozzle ring 7 rotating ring 8 is protruding.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the utility model, and be not used in restriction the utility model.
Exhaust gas turbocharge engine variable guide vane wheel, as depicted in figs. 1 and 2, comprise nozzle ring 6, the side of nozzle ring 6 arranges rotating ring 7, the side week of nozzle ring 6 installs several connecting rod 5, adjustable vane 1 is installed in one end of connecting rod 5, the other end fixing rotating panel 4 of connecting rod 5, the side of swivel plate 4 is connected with connecting rod 5, the opposite side of swivel plate 4 installs cylindricality block 3, cylindricality block 3 is in cylindrical, rotating ring 7 is offered several driven rocking arm groove 2, driven rocking arm groove 2 is in circular arc, each driven rocking arm groove 2 coordinates with a cylindricality block 3, cylindricality block 3 can rotate in driven rocking arm groove 2.
The utility model proposes the design proposal of adjustable vane 1 nonuniform mutation operator adopting nozzle ring 6 in variable nozzle turbocharger, along the circumferential direction size is unequal mutually for the initial settling angle degree of each adjustable vane 1, its setting angle and adjustable vane 1 inlet air flow angle are adapted, to meet the needs of turbo machine efficiency operation.On this basis, the utility model proposes the design proposal that a kind of structure optimization based on driving ring realizes the change of variable nozzle turbocharger adjustable vane initial settling angle degree.Without the need to processing and fabricating adjustable vane controlling mechanism installation mold again, manufacturing process is simple, and processing cost is low, and the process-cycle is short.The utility model rotating ring 7 can rotate, and rotating ring 7 drives adjustable vane 1 to rotate by driven rocking arm groove 2 with coordinating of cylindricality block 3, realizes the angle adjustment of adjustable vane 1.
Described rotating ring 7 arrange several protruding 8 side week, each protruding 8 are positioned at driven rocking arm groove 2 side.Of the present utility model protruding 8 can improve the intensity of rotating ring 7 at driven rocking arm groove 2 place, avoid rotating ring 7 to damage.
Last it is noted that the foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, although be described in detail the utility model with reference to previous embodiment, for a person skilled in the art, it still can be modified to the technological scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
