Abstract
A clamping mechanism for the end turns of a dynamoelectric machine is disclosed which permits periodic retightening and provides a means for compensating for misalignment of the clamping components. Annular spacers are provided, each of which have two nonparallel planar surfaces. When two of these spacers are combined in a coplanar association, they can be rotationally positioned relative to each other to provide spatial compensation between a nut and a clamping surface which is nonperpendicular to the threaded bar with which the nut is in threaded communication. The nut and spacers are fixed to the threaded bar with a covering of thermal setting tape to prevent relative movement and possible unthreading.
