RESILIENT DAMPING SUPPORT OF TURBOMACHINE ROTOR Russian patent published in 2015 - IPC F01D25/16 

FIELD: machine building.

SUBSTANCE: resilient damping support of turbomachine rotor contains a bearing, and shell secured on its external raceway, it is connected with stator elements using the split bushing. Between the stator element and shell a ring piston is installed, in it a control cavity is made at the side opposite to the split bushing. The control cavity is limited by the lid rigidly secured on the stator element, and is connected with the oil supply channel passing through the lid. Part of surface of the ring piston and mating surface of the stator element are made cone relatively to the longitudinal axis of the support with creation between them of the damping cavity. Between the stator element and shell a spring is installed, it contacts at the ends with a ring piston and shell.

EFFECT: invention increases reliability of the support of the turbine machine rotor due to widening of range of the work speeds of rotation of the rotor and decreasing of the dynamic deflections of the rotor, and vibration loads acting on the support.
