Turbo charger structure that insulates against heat

The utility model discloses a turbo charger structure that insulates against heat, including thermally-insulated shroud, turbine shroud, bearing casing, G type clamp, the thermally-insulated shroud centre gripping is between turbine shroud, bearing casing, in the thermally-insulated shroud centre gripping department of turbine shroud, bearing casing, the turbine shroud has the flange respectively with the bearing casing, by the flange of the tight turbine shroud of G type clamp binding clip and bearing casing, realize turbine shroud, the bearing casing centre gripping that compresses tightly to the thermally-insulated shroud. The thermally-insulated shroud border has elasticity warpage flange, the thermally-insulated shroud with the elasticity warpage flange elastic compression centre gripping at border between turbine shroud, bearing casing, thermally-insulated shroud and turbine shroud, bearing casing line contact, under long-term high temperature condition, G type clamp appears connecting when becoming flexible, and elasticity warpage flange produces the elastic restitution and is out of shape, realizes being in permanent sealing contact between thermally-insulated shroud elasticity warpage flange, turbine shroud, the bearing casing, guarantee that high temperature waste gas does not reveal.
