Abstract

The gap adjacent the tips of the blades (not shown) of a rotor 50 in a turbine type power plant is prevented from increasing, as a result of rotor sag occasioned when an oil damped bearing 48 is utilized, by cantilevered springs 70 connecting the bearing support ring 56 to housing 72. Seals 59, 60 and rings 56, 64 define an annular chamber containing the damping oil. <IMAGE>
