Abstract
The invention provides a turbocharger heat insulation hood high in deformation resistance. The structural shape of an original heat insulation hood is changed, after punch forming, the angle R, located on the edge of the upper outer circle, of the heat insulation hood is enlarged to generate tension, and after the heat insulation hood is assembled and used, the heat insulation hood is not prone to plastic deformation, namely deformation resistance of the heat insulation hood is enhanced, and the service life of a turbocharger is prolonged. The turbocharger heat insulation hood high in deformation resistance has the advantages of being simple in structure, good in sealing effect, long in service life and the like, effectively protects the overall performance of the turbocharger, has a satisfying effect after being put to the market, and is well received by clients.
Description
Technical field
The present invention relates to a kind of auto parts machinery, particularly relate to the thermal insulating cover for turbocharger that a kind of non-deformability is strong.
Background technique
Thermal insulating cover for turbocharger.It is positioned at the turbine case of exhaust-gas turbocharger and the binding site of intermediate, closely cooperates with turbine case and intermediate, and majority has certain crush.The effect of thermal shield is to stop the high heat of engine exhaust in turbine case too much to conduct to the intermediate that comprises High Rotation Speed component, stops the multiple vitals of pressurized machine to be subject to temperatures involved, optimizes pressurized machine internal work environment.In use for some time, thermal shield easily produces plastic deformation to existing thermal shield, cause thermal shield cannot with fixed tray on turbine case and intermediate close contact, thereby reduce thermal shield heat-insulating and sealing ability.Make the gap that in turbine case, high-temp waste gas is out of shape generation by thermal shield flow to intermediate and motion assembly, the heat of high-temp waste gas and carbon distribution can make very soon the moving parts of motion assembly be out of shape and be stuck, and then cause the pressurized machine life-span reduce and damage.
Summary of the invention
The object of the invention is the defect and the deficiency that exist for overcoming above-mentioned prior art, and the thermal shield that a kind of non-deformability is strong is provided
The technological scheme adopting is:
The thermal insulating cover for turbocharger that a kind of non-deformability is strong, it is characterized in that changing the structure shape of original thermal shield, after impact briquetting, superincumbent outer circular edge strengthens thermal shield R angle and produces tension force, after assembling is used, thermal shield is difficult for forming plastic deformation, and thermal shield non-deformability strengthens, and has extended the working life of pressurized machine.
The present invention has simple in structure, and the advantages such as good sealing effect, long service life have effectively been protected the overall performance of turbosupercharger, after putting goods on the market, obtain promising result, are subject to client's favorable comment.
