DEVICE FOR TWO-SIDE TRANSMISSION OF AXIAL FORCE(VERSIONS) Russian patent published in 2004 - IPC

FIELD: power engineering. SUBSTANCE: invention relates to steam turbine building and is designed for improving turbines in use. Proposed device for two-side transmission of axial force (version 1) coupling housing and housing support is arranged near plane of support sliding along foundation frame and in longitudinal plane of symmetry of turbine and it includes projection on housing, cross catch and grip, catch being welded under projection on housing, and grip being made in form of clamp installed on housing support and enclosing catch on housing projection from below. Horizontal pushing and pulling inserts are installed at both sides of catch between catch and clamp. Device for two-side transmission of axial force (version 2) coupling turbine housing and housing support is arranged close to plane of support sliding along foundation frame and in longitudinal plane of symmetry of turbine and it includes projection on housing, cross catch and grip, catch being installed on housing support, grip is made in form of clamp welded under projection of housing and enclosing catch on housing support from below, and horizontal pushing and pulling inserts are installed at body sides of catch between catch and clamp. Proposed invention makes it possible to provide jamming close to plane of sliding of support along foundation frame (according to design version 1) and strength of all fragments of device (according to design version 2). Use of horizontal pushing and pulling inserts provides reliable two-side transmission of axial as said inserts are fitted to place, and provision of required small clearances at use of known devices on operating turbine is impossible. EFFECT: improved operation of turbines. 3 cl, 2 dwg
