Abstract
Keybars for affixing stator core laminations to annular web plates of a stator frame include a cylindrical portion and a dovetail portion. The cylindrical portion is closely fitted within accurately bored axially aligned circular holes in the annular web plates. During preliminary assembly, the cylindrical portions of the keybars are inserted into the aligned bored cylindrical holes in the annular web plates with the dovetail portions facing radially inward. Due to the accuracy with which the bored cylindrical holes are positioned, chordal positioning of the keybars prior to welding is achieved with a jig positionable between adjacent keybars. During welding, the keybars are pulled radially inward to place all clearances between the circular portions and the bored cylindrical holes radially outward of the cylindrical portion.
