SEGMENT OF SLIDING SUPPORT Russian patent published in 2016 - IPC F16C17/12 F16C27/02 F16C32/06 

FIELD: machine building.

SUBSTANCE: invention relates to machine building and can be used in all industries both main element and axial and radial supports operated with forced feed of lubricant. Lubricant can be used either grease, either liquid or gaseous. In last case proposed design can be used in supports of machines intended for operation in extreme conditions: in aggressive media at high or low pressures and temperatures. Segment of sliding support consists of two parts moving to take up load on rotor side, and stationary one connected with machine body. In fixed part there is channel for supply of lubricant from source, and in movable part of segment there are channels for supply of lubricant in working gap of support, i.e. in gap between working surface segment and shaft neck or rotor foot. Segment also includes elastic support element made in form of flexible membrane of annular shape. Inner edge of membrane is attached to back surface of movable part of segment, wherein in fastening element there is channel for supply of lubricant in movable part from cavity in fixed part. Outer edge of membrane is connected to fixed part of segment, wherein membrane with cavity forms flow chamber. In centre of fixed part bottom there is threaded hole to allow access to fixing element during assembly and disassembly of segment structure. In operating condition of structure hole is tightly closed with screwed plug.

EFFECT: technical result is provision of self-adjustment of movable part of segment, elimination of leakage of lubricant from inner cavity into environment, improving vibration isolating properties of support with disclosed segments.
