ABSTRACT:
A speed reducer gear box comprising input, intermediate and output shafts rotatably mounted in a gear case. A hydraulic motor or the like is connected to the input shaft and is adapted to rotate the same. The intermediate shaft has a helical gear mounted thereon which is in mesh with a gear tooth portion on the input shaft whereby rotation of the input shaft by the hydraulic motor causes rotation of the intermediate shaft. A helical gear is also mounted on the output shaft for rotation therewith and is in mesh with a gear tooth portion on the intermediate shaft. A flywheel is mounted on the input shaft for rotation therewith to provide inertia to stabilize and to smooth out the operation of the gear box.
