ABSTRACT:
A retrofit emergency lubrication system utilizing friction-hydrostatic drive is disclosed. The retrofit system provides an emergency lubrication system backup to existing bearing lubrication systems such as for turbine-generator rotors. The retrofit system utilizes actuators to detect low bearing oil pressure and to activate resilient wheels to contact the rotor which drive high pressure pumps. The high pressure pumps in turn drive a hydraulic motor pump which in turn drives an oil supply tank pump.
