Background technique
Nozzle ring component with variable cross section is the critical component in current advanced variable geometry turbocharger, the Chinese patent being 201120544236.3 as the patent No. discloses a kind of nozzle ring component with variable cross section, in its technological scheme, pin is fixed on shifting disc, shift fork is enclosed within pin, the afterbody of blade is connected with shift fork, like this, when shifting disc rotates by external force, pin will drive shift fork to rotate, shift fork drives blade rotary then, to change blade angle, regulate flow area, when pin drives shift fork to rotate, relative sliding can be produced between pin and shift fork, and be linear contact lay between pin and shift fork, area of contact is less, like this, when relative sliding, pin and shift fork are easier to be worn, pin and shift fork wear and tear comparatively greatly, the contacting point of pin and shift fork will be made to be out of shape, will make pin and shift fork cannot normally transmission between the two, this nozzle ring capable of changing cross sections cannot normally be used, bring potential safety hazard, in addition, in its technological scheme, shifting disc is placed in the restriceted envelope of mounting disc and position limit pin formation, and position limit pin needs to push down with the spiral case of turbosupercharger to position, and between spiral case and position limit pin, there is certain gap, when turbosupercharger high temperature and high speed works, easily cause the axial float of position limit pin, shifting disc will be made to be shifted, shift fork will to be made to depart from shifting disc, this nozzle ring assembly will be made so normally to work.
Summary of the invention
Technical problem to be solved by this invention is, provides a kind of turbosupercharger nozzle ring capable of changing cross sections wearing and tearing less in the process of bearing pin and shift fork relative sliding.
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, the annulus that described mounting disc comprises cylindrical portion and extends radially outwardly from one end of cylindrical portion;
One is rotatingly nested with the shifting disc in cylindrical portion;
Multiple bearing pin be connected on shifting disc; And
Multiple shift fork, one end of described shift fork is connected and synchronous axial system one to one with blade, and the other end of shift fork is provided with a breach;
Each described bearing pin is all rotatably equipped with a sliding sleeve, shift fork is nested with on sliding sleeve one to one by breach, sliding sleeve can freely rotate and slide in the breach of shift fork, shape and the breach of sliding sleeve match, the outer wall of sliding sleeve is roughly square, and the surface of contact of the two side of the outer wall of sliding sleeve and the breach of shift fork is plane.
Described cylindrical portion is nested with and is fixed with one for carrying out the limiting gasket of axially locating to shifting disc, the periphery wall of described cylindrical portion is provided with an annular boss, one end face of shifting disc and annular boss offset, and other end and the limiting gasket of shifting disc offset.
After adopting above structure, the present invention compared with prior art, has following advantage:
In the inventive solutions, rotatingly on bearing pin be equipped with a sliding sleeve, shift fork is nested with on sliding sleeve by breach, when bearing pin drives shift fork to rotate, relative sliding is produced between sliding sleeve and shift fork, and the surface of contact between sliding sleeve and shift fork is plane, namely between sliding sleeve with shift fork for face contacts, area of contact is larger, make in the process of sliding sleeve and shift fork relative sliding, sliding sleeve and the wearing and tearing suffered by shift fork less, the contacting point of sliding sleeve and shift fork is made to be not easy abrasion deformation, make the reliable transmission between bearing pin and shift fork higher, make nozzle ring capable of changing cross sections operational safety of the present invention higher.
In addition, axially locating can be carried out to shifting disc by limiting gasket, the annulus of mounting disc can carry out radial location to shifting disc, like this, shifting disc is all reliably located in the axial direction with in radial direction, and when turbosupercharger high temperature and high speed works, shifting disc location is firm, shift fork can be avoided to depart from shifting disc, to ensure the normal use of nozzle ring capable of changing cross sections of the present invention.
