SEALING ASSEMBLY WITH NON-CONTACT LABYRINTH (VERSIONS), AND ITS MANUFACTURING METHOD

摘要

FIELD: machine building. ^ SUBSTANCE: sealing assembly consists of external stiff holder and internal coupling. Holder has external cylindrical flange and support branched to the inner side in radial direction. Coupling has cylindrical wall and flange branched to outer side in radial direction. At least to one of two parts which are represented with support and coupling there attached is solid component that provides, at least partially, fully non-contact labyrinth passing between holder and coupling. Versions of design of sealing assembly and its manufacturing method is described. ^ EFFECT: higher sealing reliability. ^ 29 cl, 7 dwg
