In a first embodiment of the invention, a gear ratio multiplier has directly cooperating gears which serve to rotatably connect an input shaft (20) to an output shaft (22) through an intermediate shaft (24). The input and outputs shafts have parallel axes of rotation and extend, respectively, from seals (26, 28) in opposite sides of a housing (30). The inner ends of the input and output shafts are spaced from one another and are each provided with a pinion gear (18, 12). 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 (16, 14) having different numbers of teeth are affixed on the intermediate shaft. The pinion gear on the input shaft (18) engages the ring gear (16) on the intermediate shaft whereas the pinion gear on the output shaft (12) engages the ring gear (14) on the intermediate shaft. The diameter pitch varies according to the application as does the tooth size and tooth number of the gears. |
