Description
Technical field
The utility model belongs to turbo-charger technical field, relates to a kind of heat insulation structure of turbocharger.
Background technique
Existing turbosupercharger is heat insulation comprises thermal shield, turbine shroud, bearing housing, G type clip; Thermal shield contacts with turbine shroud, cartridge housing dignity, is clamped between turbine shroud, bearing housing; In thermal shield clamping place of turbine shroud, bearing housing, turbine shroud and bearing housing have flange respectively; By the flange of the fastening clamping turbine shroud of G type clip and bearing housing, realize turbine shroud, bearing housing to the compression clamping of thermal shield.Thermal shield reduces turbine case side heat to the diffusion of cartridge housing side, ensures that turbosupercharger can reliably operate; Can prevent the high-temp waste gas in turbine shroud from being revealed by the gap between bearing housing, turbine cylinder simultaneously, improve turbine efficiency.Its shortcoming is: thermal shield contacts with turbine shroud, cartridge housing dignity, adds heat transfer, makes more heat be delivered to bearing housing by thermal shield and turbine shroud, cartridge housing dignity contact area, reduces turbosupercharger maintainability; G type clip is under long term high temperature condition, often occur that the connection between thermal shield clamp face, bearing housing, turbine shroud loosens, thermal shield contacts occur gap with turbine shroud, cartridge housing dignity, causes high-temp waste gas to be revealed from the gap of three, reduces turbine efficiency.
Summary of the invention
The utility model discloses a kind of heat insulation structure of turbocharger, contact with turbine shroud, cartridge housing dignity to solve thermal shield edge in prior art, add heat transfer, make more heat be delivered to bearing housing by thermal shield and turbine shroud, cartridge housing dignity contact area, reduce turbosupercharger maintainability; G type clip is under long term high temperature condition, and Flange joint district, bearing housing, connect between turbine shroud and loosen, high-temp waste gas is revealed from three gap, reduces the problems such as turbine efficiency.
The utility model comprises thermal shield, turbine shroud, bearing housing, G type clip; Thermal shield is clamped between turbine shroud, bearing housing; In thermal shield clamping place of turbine shroud, bearing housing, turbine shroud and bearing housing have flange respectively; By the flange of the fastening clamping turbine shroud of G type clip and bearing housing, realize turbine shroud, bearing housing to the compression clamping of thermal shield.
The utility model thermal shield edge has elasticity warpage flange; Thermal shield is clamped between turbine shroud, bearing housing with the elasticity warpage flange elastic compression at edge; Thermal shield and turbine shroud, bearing housing linear contact lay; Under long term high temperature condition, when G type clip occurs connecting loosening, elasticity warpage flange produces elasticity and recovers distortion, realizes being in permanent seal contact between thermal shield elasticity warpage flange, turbine shroud, bearing housing.
Good effect of the present utility model is: reduce heat transfer, improve the reliability of turbocharger operation; Thermal shield is clamped between turbine shroud, bearing housing with the elasticity warpage flange elastic compression at edge; Permanent seal contact between thermal shield elasticity warpage flange, turbine shroud, bearing housing, thus ensure that high-temp waste gas is not revealed.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model heat shield structure schematic diagram;
Fig. 3 is the utility model heat shield structure sectional view;
In figure: 1 thermal shield, 2 turbine shrouds, 3 bearing housinges, 4 G type clips, 1a elasticity warpage flange.
Embodiment
An embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.
The utility model embodiment as shown in Figure 1, comprises thermal shield 1, turbine shroud 2, bearing housing 3, G type clip 4; Thermal shield 1 is clamped between turbine shroud 2, bearing housing 3; In thermal shield clamping place of turbine shroud 2, bearing housing 3, turbine shroud 2 and bearing housing 3 have flange respectively; By the fastening clamping turbine shroud 2 of G type clip 4 and the flange of bearing housing 3, realize the compression clamping of turbine shroud 2, bearing housing 3 pairs of thermal shields 1.Thermal shield 1 edge has elasticity warpage flange 1a; Thermal shield 1 is clamped between turbine shroud 2, bearing housing 3 with the elasticity warpage flange 1a elastic compression at edge; Thermal shield 1 and turbine shroud 2, bearing housing 3 linear contact lay; Under long term high temperature condition, when G type clip 4 occurs connecting loosening, elasticity warpage flange 1a produces elasticity and recovers distortion, realizes being in permanent seal contact between thermal shield elasticity warpage flange 1a, turbine shroud 2, bearing housing 3; Due to thermal shield 1 and turbine shroud 2, bearing housing 3 linear contact lay, reduce the heat transfer from turbine shroud 2 to bearing housing 3, improve turbosupercharger maintainability.
Listed a series of detailed descriptions are only illustrating for the utility model feasibility mode of execution; they are also not used to limit protection domain of the present utility model, all do not depart from the utility model equivalent implementations of doing of essence or change all should be included within protection domain of the present utility model.
