Abstract
An anti-windage device is provided for use on the couplings formed by mating flanges of rotors for turbomachines, such as steam turbines and the like. The anti-windage device is comprised of upper and lower anti-windage ring segments. The anti-windage ring segments have holes for each of the nuts that are threaded onto the bolts that join the mating flanges into a rotor coupling. The holes enclose the nuts and the anti-windage ring segments fill the circumferential spaces between adjacent nuts. The ring segments are secured to the rotor flange by causing the nuts to bear against an annular lip formed in each hole. The depth of the holes and the axial thickness of the anti-windage ring is such that the end faces of the anti-windage ring, nuts and bolts are flush, thereby forming a smooth surface that minimizes windage.
