Abstract
A bearing housing for a heavy rotor is made axially-nonsymmetrical so that the bearing chamber therein is shifted axially of the rotor shaft upon reversing the bearing housing. With a new rotor, the nonsymmetry positions the bearing chamber axially outwardly from the housing center. When necessary, the rotor shaft, by virtue of having successively increased diameters inwardly from its end, can be reworked by turning new surfaces thereon positioned axially inwardly from the original surfaces. The bearing housing is then reversed so that its nonsymmetry locates the bearing chamber inwardly from the housing center, to accommodate the new positions of the shaft surfaces.
Claims5
A bearing housing having positioning formations for cooperating with securing means to predetermine the axial location of a housing-base center along an axis extending through the bearing housing, and structure located with axial nonsymmetry with respect to said formations to provide a bearing chamber the center of which is axially displaced from said base center, said bearing housing being, in part at least, reversible so that the axial displacement of the center of the bearing-receiving chamber will be displaced axially in the opposite direction from the direction of the original displacement, the bearing housing being adapted to receive a shaft end with its diameters increasing in the direction inwardly from the end of the shaft providing shaft dimensions within which the shaft can be reworked to bearing-contours similar to its original bearing-contours but relocated inwardly to match the inward shifting of the center of the bearing-receiving chamber upon reversal of the bearing housing parts.
A bearing housing member having positioning formations for cooperating with securing menas to predetermine the axial location of a housing-base center along an axis extending through the bearing housing, and a housing ring having a bearing-receiving chamber therein located with axial nonsymmetry with respect to said formations to be axially displaced from said base center, said bearing housing member being reversible so that the axial displacement of the bearing-receiving chamber will be displaced axially in the opposite direction from the direction of the original displacement, the bearing housing member adapted to receive a shaft end with its diameters increasing in the direction inwardly from the end of the shaft providing shaft dimensions within which the shaft can be reworked to bearing-contours similar to its original bearing-contours but relocated inwardly to match the inward shifting of the center of the bearing-receiving chamber upon reversal of the bearing housing member.
