Abstract
A cover arrangement is provided for covering radial rotors of turbo machines such as impellers of gas turbine engines. The arrangement includes two cover halves extending respectively one half of the circumferential distance around the impeller rotor and connected at the edge portions by connecting flanges. In order to accommodate a balancing of the cover arrangement and uniform spacing between the cover arrangement and the impeller, the cover halves are provided with rib portions which are evenly spaced around the perimeter and which are shaped and configured similarly to the connecting flanges. In preferred embodiments, the rib members and the connecting flanges are constructed with similar moments of inertia, thermal capacities, and bending resistances, to further assure uniformity around the periphery of the cover arrangement. In particularly preferred embodiments, each cover half includes two rib portions between the respective edge connecting flanges, which are equally spaced from one another and the flanges. In preferred embodiments, the cover halves are carried by the machine casing via bolts supported at the casing and extending through collar-shaped wall sections equally spaced around the perimeter of the cover arrangement at the cover halves.
