Description
Technical field
The present invention relates to turbosupercharger, especially relate to the nozzle ring assembly in turbosupercharger.
Background technique
As everyone knows, turbosupercharger is for air-intake of combustion engine supercharging, promote the product of working efficiency of internal combustion engine, it is the turbine blade that the exhaust-driven turbocharger of being discharged by internal-combustion engine is installed on exhaust end on outlet pipe, the air end of booster blade rotary work done being installed on the turbosupercharger of intake lines of combustion engines is coaxially driven to carry out supercharging again, suction pressure is got a promotion, improve engine conditions. promote the power of internal-combustion engine. the blade wherein in nozzle ring component with variable cross section is the rotation by several angle, change exhaust cross-sectional sizes, thus regulate turbocharger exhaust pressure, control turbo charger speed, and then control the component of boost pressure, nozzle ring component operation is under the high temperature and high pressure environment of about 600 DEG C ~ 1200 DEG C, thus require that nozzle ring assembly has high mechanical property and machining accuracy.
Present turbosupercharger nozzle ring component with variable cross section also has following problems at work, one is drive plate when driving blade rotary by driven fork, due to drive plate in level (radial direction) although have in face roll guiding, but due to can bob be produced at vertical surface (axis) when roller rotates, and intermediate and roller have more than 0.3mm gap, therefore drive plate meeting bob, thus the non-circular motion that when forming work, bob is larger, easily cause drive plate not working, even stuck, affect nozzle ring functional reliability; Two is ask for something high temperature-resistant parts is formula body alloyed steel difficult to understand, and generally do not do heat treatment, surface hardness is generally not more than 300HV(and is about 290HB), fatigue resistance and durable mill are strong, and mutual friction factor is large, and its surface is not only, corner angle easily draw bad and come off; Three are existing backing plate blade faces is same level, and during work, nozzle blade and backing plate easily produce scratch, increases running resistance.
Summary of the invention
For the problem in above-mentioned prior art existing for nozzle ring assembly, the invention provides one can make to stir dish and beat radial and axial all can not generation, thus the generation of non-circular motion when effectively preventing work, guarantee that drive plate goes slick, that guarantees to start working stability can the turbine supercharger nozzle ring components of two-way location.
The technological scheme that the technical problem to be solved in the present invention is taked is: the turbine supercharger nozzle ring components of described two-way location comprises mounting disc, drive plate, backing plate, initiatively fork and driven fork, described driven fork is disposed on mounting disc side, driven fork one end is connected with rotating shaft one end, the rotating shaft the other end is connected with the blade be disposed on another opposite flank of mounting disc, described drive plate is interval with annular groove, the described driven fork the other end is embedded in annular groove, initiatively fork is between driven fork, initiatively fork one end is embedded in annular groove, initiatively the fork the other end is connected with driving mechanism, mounting disc is movably set with and the position limit pin contacted inside drive plate, in mounting disc, interval is movably set with roller, described roller cross section is I-shaped, described roller roller pin is connected with mounting disc, roller pin and mounting disc are interference fit, roller pin upper end is with limited step, roller pin and roller are Spielpassung.
Further, described drive plate, active fork, driven fork and backing plate carry out nitriding treatment.
The present invention carries out two significant improvement on existing nozzle ring basis, one is for first technical problem in solution prior art is by changing structure and the means of fixation of roller, change the cylindric of original roller pin the stepped cylindrical shape of upper end with limited step into, change the interference fit of original roller pin and roller into Spielpassung, change the Spielpassung of original roller pin and mounting disc into interference fit, thus roller pin non rotating at work, roller rotates, because roller pin is fixed in mounting disc, roller can be made can not to produce in axis (Vertical direction) by limited step to beat, both can guarantee that roller fully contacted all the time with drive plate in horizontal plane, roller can be prevented again, the upper and lower play of drive plate, guarantee that drive plate goes slick, two is, for solving second technical problem in prior art, part key components and parts is carried out nitriding treatment, not only bulk strength and hardness improve to make these parts, and improve gloss and the wear resistance on surface, make component surface more gloss, reduction friction factor, corner angle remain complete, clear, do not draw bad and come off, while improving fatigue resistance, reduce the driving force needed for drive plate, improve the flexibility of running, three is, for solving the 3rd technical problem in prior art, backing plate and blade opposing side are arranged to inclined-plane, under not affecting nozzle ring performance prerequisite, improves the scratch of blade and backing plate, thus reduces blade movable resistance, improve the flexibility of running.
The invention provides one can make to stir dish and beat radial and axial all can not generation, and part nitrogenize and backing plate partial-band inclined-plane, the generation of non-circular motion when not only can effectively prevent drive plate from working, guarantees that drive plate goes slick, and also improves nozzle ring fatigue resistance, reduce the driving force needed for drive plate, improve going slick property, additionally reduce the scratch of blade and backing plate, thus reduce blade movable resistance, improve going slick property, guarantee to start working stability.
