    专利说明:

    The invention relates to mechanical engineering and can be used in the lubrication systems of internal combustion engines.
    Oil-cast oil trays for an internal combustion engine are known, having a bottom and side flaps for attaching the sump to an engine block lj.
    However, the known pallets are characterized by insufficient sound attenuation performance.
    The purpose of the invention is to increase the efficiency of sound attenuation.
    Accomplishment of the goal in an oil-cast oil pan for an internal combustion engine, comprising a bottom and side walls with flanges for attaching the pan to the engine block, the side walls are stepped and provided with corrugations and flat sections alternating evenly with each other, the corrugation wall thickness equal to the wall thickness of flat sections, and the bottom and side walls are provided with stiffening ribs.
    FIG. 1 schematically shows the oil casting pan in FIG. 2 is the same, top view, in FIG. 3 shows section A-A in FIG. 2. I The oily casting pallet contains the bottom 1 and side walls 2 with flares 3 for attaching the pallet to the engine block. The side walls are stepped with steps 4-7 and are provided with corrugations 8 and flat sections 9 alternating evenly with each other, the wall thickness of the corrugations 8 being equal to the wall thickness of the flat sections 9.
    The side walls of the first stage 4 and the bottom 1 are provided with corrugations arranged perpendicularly to each other in such a way that relatively small, almost square flat sections remain. The side walls 2 and the bottom 1 are also provided with stiffening ribs,
    When the engine is operating, the noise is damped due to the fact that the surfaces of the pallet, equipped with corrugations and stiffening ribs, have a high absorption efficiency of sound waves within a narrow range.
    The application of the invention makes it possible to significantly increase the effectiveness of sound attenuation.
