DREHZAHLVERAENDERLICHES GETRIEBE

摘要

A change-speed gearbox has coaxial input and output shafts. Five intermediate shafts are equi-spaced around the input shaft and each has two gears fixed thereto, one of which meshes with a common gear on the input shaft, the intermediate shafts being movable axially. Five gears of different diameters are fixed to the output shaft around which five secondary shafts are carried by a rotatable cage. The five secondary shafts each have two gears fixed thereto, one of which meshes with a different one of the gears on the output shaft. Any one of a possible twenty five gear ratios between the input and output shafts may be obtained by rotating the cage until a selected one of the secondary shafts is in the same radial plane as a selected one of the intermediate shafts, that intermediate shaft then being moved axially to bring the second gear thereon into mesh with the second gear on the selected secondary shaft.
