ABSTRACT:
Power transmission gearing has two countershafts both of which are mounted with virtually no capability of axial movement and drivably connected to a common driving shaft and a common driven shaft by gearing. The gearing which connects the countershafts to the driven shaft conprises a single helical gear of one hand on one of the countershafts, a single helical gear of the other hand on the other of the countershafts, and a double-helical gear assembly on the driven shaft, one toothed zone of the doublehelical gear assembly meshing with one of the single helical gears and the other toothed zone of said assembly meshing with the other of said gears. The double-helical gear assembly is capable of axial movement on the driven shaft to equalize the torque transmitted by each countershaft.
