Abstract
Abstract A method of assembling a rotatable member with bearing means of a structural component for a dynamoelectric machine. In this method, the structural component is disposed upon means for fixturing it with the bearing means being engaged with means for supporting it which is movable in the fixturing means. The structural component and supporting means are conjointly displaced generally toward predeterminately spaced apart locating surfaces on the fixturing means to engage at least a portion of the structural component with one of the locating surfaces, and the supporting means is maintained in its displaced position. The rotatable member is moved relative to the bearing means into assembled relation therewith and into engagement with the other of the locating surfaces for terminating the rotatable member movement. Other methods of assembling and apparatus for assembling a rotatable number with bearing means of a structural component for a dynamoelectric machine are also disclosed.
