FIELD: machine building.SUBSTANCE: rotation device contains fixed support (11) and movable support (12) designed with possibility of rotation around fixed support (11) and around axis (140) of rotation and device for connection of fixed (11) and movable (12) supports, which contains bearing designed with possibility to direct support (11) upon its rotation around support (12), flexible dynamic sealing (1) designed with possibility of tight seal between supports (11, 12) installed between frictional path (4) attached to one of supports (12 or 11) and mechanical structure attached to the other support (11 or 12). Tight seal includes metal spring (5) designed with possibility of contact force of sealing between path (4) and mechanical structure. Seal (1) is installed parallel to axis (140) so that contact force is applied parallel to axis (140). Support (11) contains gaskets (19), and seal (1) contains extended elements (14) distributed along seal (1) and meant for embedding of gaskets (19) to provide star-shaped direction of seal.EFFECT: producing guiding device for rotation which provides better performance, in particular due to static tight sealing between mechanic elements attached to each other and dynamic tight sealing in frictional part.6 cl, 9 dwg |
