ABSTRACT:
Mechanical transmission apparatus having a pair of first and second shafts mounted in a housing, and a gear train mounted thereon. A first small gear mounted on the first shaft meshes with a second large gear mounted on the second shaft. A third small gear mounted on the second shaft is fixedly connected to the second gear and meshes with a fourth large gear mounted on the first shaft. Each one of the large gears has substantially the same number of teeth and each one of the small gears has substantially the same number of teeth. A source of power is coupled to the gear train, and one of the first and second shafts is coupled drivingly to a load. One of the gears of the gear train is fixed to its one of the first and second shafts, whereby power is transmitted from the source through the gear train to the load. The gear train includes a first set of axially aligned gears arranged in pairs of fixedly connected together gears, and a second set of axially aligned gears arranged in pairs of fixedly connected together gears. Each pair of the first set intermeshes with a corresponding one of the pairs of the second set of axially aligned gears, whereby the second and third gears are one of the pairs of fixedly connected together gears of one of the first and second sets of gears, and the fourth and fifth gears are one of the pairs of fixedly together gears of the other one of the first and second sets of gears.
