A gear drive has two closely spaced parallel output shafts driven by a single input shaft. One gear train connects the input shaft to one of the output shafts which has a thrust bearing at one end to absorb thrust loads. A second gear train connects the input shaft to the second output shaft. The second output shaft mounts a double helical pinion which is in engagement with two double helical gears on a pair of spaced shafts. The spaced shafts are each mounted in thrust bearings to absorb the thrust on the second output shaft which is transmitted through the meshings double helical gearing to the pair of shafts. A linkage engages the ends of the pair of shafts to equalize the thrust load on each of the two shafts. |
