ABSTRACT:
A dynamoelectric machine end shield for closing the ends of a cylindrical shell, the end shield comprising a pattern of valleys and plateaus to create a reinforcing rib pattern that provides increased strength. The end shield, which may be formed from thin cross section sheet material, provides a close fitting rabbet that does not require machining and provides a structure that will not transmit possible distortion of the lighter gauge material from the mounting bolts to the bearing. Because of the additional strength afforded by the reinforcing rib pattern, radially inward displacement of the extended portions of extended clamp bolts also is minimized.
