Abstract
Abstract A radial centering device for high speed transmission couplings of the type having a ball-and-socket joint. The ball is disposed at the end of an extension of a first shaft and the socket is disposed at the end of an extension of a second shaft. A first bearing is interposed between the needle or roller and the extension of the first shaft and a second bearing is interposed between the socket and the extension of the second shaft. The ball sliding relative to the shaft on during a change of the operating between the two shafts.
