ABSTRACT:
A transmission for two driven shafts which are parallel to and at a small spacing from one another and which drive the twin screws of the extruder wherein each shaft has a respective driven pinion thereon with the two pinions axially displaced with respect to one another and for each pinion there is a respective drive each comprising three intermediate gears equiangularly disposed around the pinion and meshed therewith, a ring gear surrounding and meshed with the three intermediate gears and drive means to rotate the ring gear, the pinion and two of the three intermediate gears not having any mountings, i.e. floating, and the third intermediate gear being free to move in directions radially of the pinion thereby to obtain equal division of drive power between the three intermediate gears and avoid forces tending to move the pinion radially.
