Abstract
The utility model discloses a but variable cross section nozzle cascade structure, including stir set, blade weld assembly, special screw, distance cover, back lid and initiative shift fork, the one end of stirring the dish is equipped with the blade weld assembly, the one end of blade weld assembly is equipped with the distance cover, through special screw connection between distance cover and the blade weld assembly, the one end outside at the distance cover is installed to the back lid, this but variable cross section nozzle cascade structure has got rid of the locating hole to use bolted construction to substitute the connection, have low cost, installation convenient to use, the reliability is high, life increases more than 1 times, the connecting piece becomes a general standard purchase production convenient and fast by the production piece, but further made the contribution for the popularization of variable cross section nozzle cascade booster.
Description
Technical field
The utility model belongs to nozzle ring technical field, and in particular to a kind of nozzle ring capable of changing cross sections structure.
Background technology
The nozzle ring capable of changing cross sections is used to improve prior involvement of the turbocharger in low engine speed, general turbine
Supercharged engine is only reaching specified rotating speed（8000 turns）Work can be just intervened during the above, under many circumstances booster is simultaneously
Do not work；Because the work operating mode of booster is hyperpyrexia, high pressure, requires related accessory and have very high high temperature resistant and coordinate constant
Shape such that it is able to smoothly execution.Existing nozzle ring design stirs ring with support plate in nozzle ring capable of changing cross sections
Connection stirs ring using a pad+roller to support, and due to high thermal high, pad is relatively thin to bear high temperature and high pressure environment work
When be easily deformed and cause to stir ring and cannot move stuck, cause nozzle ring to fail so that booster fails, it is impossible to carry for engine
For suitable power.
Original structure uses turbine bushing connection nozzle ring and booster, turbine bushing complex manufacturing technology, it is difficult to process, easily
Deform, service life is short, poor reliability, size is difficult to be precisely controlled.
The content of the invention
The purpose of this utility model is to provide a kind of nozzle ring capable of changing cross sections structure, to solve above-mentioned background technology in carry
The problem for going out.
For achieving the above object, the utility model provides following technical scheme：A kind of nozzle ring capable of changing cross sections structure, including
Shifting disc, blade weld assembly, screw, spacer sleeve, bonnet and actively shift fork, one end of the shifting disc is provided with blade welding group
Part, one end of the blade weld assembly is provided with spacer sleeve, is connected by screw between the spacer sleeve and blade weld assembly,
The bonnet is arranged on one end outside of spacer sleeve.
Preferably, the outer end edges of the shifting disc are provided with actively shift fork and actively shift fork is provided with altogether 8.
Preferably, cover that to be provided between 3 screw holes, and 3 screw holes be in 120 ° of angle arranged distributions after described.
Technique effect of the present utility model and advantage：The nozzle ring capable of changing cross sections structure, eliminates location hole, and uses spiral shell
Stud structure instead of connection, with low cost, easy to install, reliability is high, service life increases by more than 1 times, connects
To be changed into universal standard Purchased Item convenient for production quick from part is produced for part, is that the popularization of nozzle ring capable of changing cross sections booster is further done
Contribution is gone out.

Fig. 3 is the structural representation of the utility model bonnet.
In figure：1st, shifting disc；2nd, blade weld assembly；3rd, screw；4th, spacer sleeve；5th, bonnet；7th, actively shift fork；8th, screw
Hole.
Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of the utility model protection.
The utility model provides a kind of nozzle ring capable of changing cross sections structure as shown in Figure 1, Figure 2 and Figure 3, including shifting disc
1st, blade weld assembly 2, screw 3, spacer sleeve 4, bonnet 5 and actively shift fork 7, one end of the shifting disc 1 is provided with blade welding
Component 2, one end of the blade weld assembly 2 is provided with described in spacer sleeve 4 and passes through spiral shell between spacer sleeve 4 and blade weld assembly 2
Nail 3 connects, and the bonnet 5 is arranged on one end outside of spacer sleeve 4, and the outer end edges of the shifting disc 1 are provided with actively shift fork 7
And actively shift fork 7 is provided with altogether 8, the bonnet 5 is provided between 3 screw holes 8, and 3 screw holes 8 in 120 ° of angle arrangements
Distribution.
Operation principle：Only three screw holes 8 need to be attacked on bonnet 5, with three common soket head cap screws by nozzle ring master
Body phase eliminates location hole even and on supercharger volute, and instead of connection using bolt arrangement, with low cost
Honest and clean, easy to install, reliability is high, service life increase by more than 1 times, connector be changed into universal standard Purchased Item from part is produced
It is convenient for production quick, it is that the popularization of nozzle ring capable of changing cross sections booster is further made that contribution.
Finally it should be noted that：Preferred embodiment of the present utility model is the foregoing is only, this is not limited to
Utility model, although being described in detail to the utility model with reference to the foregoing embodiments, for those skilled in the art
For, it still can modify to the technical scheme described in foregoing embodiments, or to which part technical characteristic
Equivalent is carried out, all within spirit of the present utility model and principle, any modification, equivalent substitution and improvements made etc.,
Should be included within protection domain of the present utility model.
