Abstract:

The Hydroflex bearing concept consists of a conventionally shaped, partial-arc gas bearing permanently attached to a leaf-spring-shaped flexure via a small-cross-section short post. When assembled into a complete bearing, small friction pads are installed so they press against the lateral face of the flexure. The Coulomb friction generated by these small flat pads provides damping for the reduction of rotor response amplitudes in the area of a critical speed. The program was promulgated to establish the feasibility of the Hydroflex bearing concept. To reach the objective of this program, the following tasks were accomplished Design of Hydroflex bearing Design of test rig and fabrication of test components Experimental evaluation of Hydroflex bearing concept. Keywords Turbomachinery Hydrodynamic gas bearing Resilence Bearing friction damper. Author
