Description
Technical field
The present invention relates to turbo-charger technical field, is specifically a kind of turbosupercharger nozzle ring capable of changing cross sections.
Background technique
Nozzle ring component with variable cross section is the critical component in current advanced variable geometry turbocharger, the Chinese patent being 200920064784.9 as the patent No. discloses a kind of nozzle ring component with variable cross section, adjustable blade burner in this nozzle ring assembly, the nozzle ring weldment that blade and shift fork solid welding form jointly leans on drive plate driven rotary thus changes blade angle, regulate flow area, in this nozzle ring assembly, roller blocks drive plate for limiting the radial position of drive plate, roller is mobilizable to be nested with on roller pin, roller pin is mobilizable to be plugged in mounting disc, roller is nested with after on roller pin to be needed to push down to position with the spiral case of turbosupercharger, certain gap is there is between roller and spiral case, when turbosupercharger high temperature and high speed works, easily cause the axial float of roller, drive plate will be made to be shifted, shift fork will be made to drop out from drive plate, this nozzle ring assembly will be made normally to use, in addition, because roller and roller pin are for being flexibly connected, when installing this nozzle ring assembly, needing roller and roller pin to install respectively, installing like this and just comparatively bothering, and roller and roller pin are easily lost in installation process, if roller is not in place when mounted, the position of drive plate will be made to offset, namely make drive plate deform, drive plate will be made cannot to drive shift fork and blade rotary reliably, and when this nozzle ring assembly will be made to use, reliability is lower.
Summary of the invention
Technical problem to be solved by this invention is, provides one that driving ring axis and radial direction are all located firmly, and easy for installation, that component are not easy loss, driving ring accurate positioning turbosupercharger nozzle ring capable of changing cross sections.
For solving the problems of the technologies described above, turbosupercharger nozzle ring capable of changing cross sections provided by the invention, comprising:
One mounting disc;
One is arranged on one end of mounting disc and the driving ring that can rotate around himself axis; And
At least three positioning elements be fixed on for positioning driving ring in mounting disc;
Described each positioning element includes integrated bearing pin portion and is arranged on the head of outer end, bearing pin portion, the equal plug-in mounting in bearing pin portion is fastened on axially to be located in the mounting hole of an end face of mounting disc, the periphery wall of head is provided with an annular groove, in the rotating annular groove being inserted into the head of each positioning element of the inwall of driving ring.
After adopting above structure, the present invention compared with prior art, has following advantage:
In the present invention, roller of the prior art and roller pin is instead of with positioning element, and the bearing pin portion plug-in mounting in positioning element is fastened in mounting disc, positioning element is fixed in mounting disc can not move, so just do not need to position positioning element with the spiral case of turbosupercharger, also the positioning element when turbocharger operation can be avoided to produce axial float, the head of positioning element is made to have carried out axial and radial location to driving ring, driving ring location is firm, and when installing nozzle ring of the present invention, roller of the prior art and roller pin can be replaced with assembly, do not need the operation carrying out roller being pressed into roller pin, nozzle ring of the present invention is installed more for convenience, nor deposit the problem that roller or roller pin in the prior art easily lose, in addition, be installed to after in mounting disc at positioning element, namely the head of positioning element accurately locates, namely driving ring can accurately locate by the head of positioning element, driving ring can be avoided as situation about deforming because roller is not in place in prior art, make drive plate can drive shift fork and blade rotary reliably, when nozzle ring of the present invention is used, reliability is higher.
