ABSTRACT:
A gear reduction assembly having directly cooperating gears which serve to rotatably connect an input shaft to an output shaft through an intermediate shaft. The input and output shafts have parallel axes of rotation and extend, respectively, from seals in opposite sides of a housing. The inner ends of the input and output shafts are spaced from one another and are each provided with an identical pinion gear. The intermediate shaft is rotatably carried between the pinion gears and has an axis of rotation positioned at right angles to the axes of rotation of the input and output shafts. A pair of differently sized ring gears having different numbers of teeth are affixed in a back-to-back relationship on the intermediate shaft. The pinion gear on the input shaft engages the relatively smaller ring gear on the intermediate shaft whereas the pinion gear on the output shaft engages the relatively larger ring gear on the intermediate shaft. The gear reduction assembly is utilized in the power train of a vehicle and is positioned between the transmission and propeller shaft to permanently reduce the gear ratio between the engine and one or more drive axles.
