Description
Technical field
The pressure shell for turbocharger is the utility model is related to, more particularly, to a kind of pressure shell for turbocharger
Air inlet sound insulation board mounting structure.
Background technology
Turbocharger is actually a kind of air compressor, increases air inflow by compressed air.It is to utilize hair
The exhaust gas inertia impulsive force of motivation discharge promotes the indoor turbine of turbine, and turbine drives coaxial impeller again, impeller force feed is by sky
The air that air cleaner pipeline is sent, is allowed to supercharging and enters cylinder.When engine speed increases, the exhaust gas velocity of discharge turns with turbine
Speed also synchronous increase, impeller just compress more air and enter cylinder, and pressure and the density increase of air can burn more
Fuel, the corresponding rotating speed for increasing fuel quantity and adjusting engine, it is possible to increase the output power of engine.
The installation of the pressure shell air inlet sound panel of turbocharger is presently used for by the way of interference fit extrudes, it is this
Assembly method causes pressure shell air inlet sound panel to need special frock when mounted, while it is big to dismantle difficulty.In the presence of dismounting inconvenience
The shortcomings that low with work efficiency.
Utility model content

The above problem existing for assembling structure.
For this purpose, the utility model uses following technical scheme：
A kind of pressure shell air inlet sound insulation board mounting structure for turbocharger, it includes pressure shell body, the pressure shell sheet
Mounting hole is offered on body, wherein, set in the mounting hole and be machined with internal thread segment, the outside of the pressure shell air inlet sound panel
Be provided with external screw thread on wall, the pressure shell air inlet sound panel is fixed on the mounting hole by external screw thread, in the mounting hole in
Limiting component is provided with the outside of the pressure shell air inlet sound panel.
Especially, the limiting component uses limit stop ring, and limiting slot, the limit stop ring are offered in the mounting hole
It is fixed in the limiting slot.
Especially, the withdrawing easy to internal thread segment processing is offered on the pressure shell body on the inside of the mounting hole
Groove.
Especially, the pressure shell air inlet sound panel includes plate body, and the outer rim of the plate body is extended with outside to homonymy bending
Wall, the wall thickness of the lateral wall are more than the thickness of the plate body.
Especially, the wall thickness of the lateral wall is more than 4 ㎜.
The beneficial effects of the utility model are the pressure shell air inlet sound insulation for turbocharger compared with prior art
Pressure shell air inlet sound panel is fixed in mounting hole by board mounting structure by helicitic texture.It is not only simple in structure；It is easily achieved；And
And it is convenient for disassembly and assembly, improve the efficiency of assembling of pressure shell air inlet sound panel.
