RESILIENT DAMPING SUPPORT OF TURBINE Russian patent published in 2015 - IPC F02C7/06 F01D25/16 

FIELD: machine building.

SUBSTANCE: in resilient damping support (1) of turbine the housing (2) contains a radial edge (7) with connected to it flanges (8) and (9) limiting a lubricant cavity (10), and the wall (11) with connected to it air supply pipes (18). The wall (11) is designed radial with a flat surface (19) of the joint with the air supply pipes (18). Between the radial wall (11) and the radial edge (7) the resilient cylindrical bridge (20) is provisioned. The ratio of the average diameter of the roller bearing D to the axial length of the cylindrical bridge L is within 2…6. The ratio of axial length of the cylindrical web L to the minimum width of the cylindrical bridge h is within 10…20.

EFFECT: by decrease of thermal tensions in the housing of the elastic damping support its reliability is improved, idle leaks of cooling air are minimised.
