SLIDING SUPPORT Russian patent published in 2003 - IPC

FIELD: mechanical engineering. SUBSTANCE: invention relates to pump and compressor building and it can be used in turbopumps and compressors. proposed sliding support has bushing, thickness δ and inner diameter D₁ and it has length of . Bushing is installed in holder with radial clearance relative to shaft tenon. Bushing is coupled with holder of axial displacement stop at side of high-pressure lubrication space and at side of low-pressure lubrication space said bushing is installed by part of cylindrical surface of length L₁≅(0,1-0,3)L in holder by fit. Bushing is mated with holder, and at side of high-pressure lubrication space ring space between bushing and holder is formed. Bushing thrusts with its end face surface against thrust bushing of housing. Ring space communicates by channels with high-pressure lubrication space. EFFECT: improved reliability and quality of operation, increased load-carrying capacity and rigidity of sliding support unit. 3 cl, 3 dwg
