ABSTRACT:
A shaft carrying a cutter head is bolted to the output shaft of a speed reducer gear in coaxial configuration and having a casing journalled on the shaft. The casing carries plural drive motors and the gear has a combining stage as input. The shafts are mounted in thrust and pendulum bearings in a frame and the casing is held against rotation on that frame. The output stage of the gear is a planetary gear with a spider from which extends the output shaft and a hollow shaft and in opposite directions. The casing is journalled on the shaft by bearings engaging the hollow shaft and the output shaft at opposite sides of the spider.
