Abstract
An improved change gear system having a plurality of spaced countershafts having parallel axes and means supporting the countershafts in a casing for rotation. Countershaft gears are provided on the countershafts and are concentric and rotatable therewith. A rotatable main shaft is provided which is arranged substantially parallel with the countershafts and is preferably located between a pair of the countershafts. Means are provided for pivotally supporting one end of the main shaft in addition to means for guiding the other end thereof in a free floating relation relative to the one end for movement in at least a direction transverse of a plane through the axes of two of the countershafts. A plurality of axially constrained thrust rings are fixed to the main shaft for rotation therewith and cooperate with a fixed thrust plate for transferring thrust loads on the main shaft to the casing. Clutching means are provided for effecting a driving connection between the countershafts and the main shaft.
