Concept for mounting bull gear eliminates need for heavy bull-gear shaft and its supporting bearings otherwise required to react large loads. Three pairs of pinion gears supply torque to bull gear. Provides lateral support, eliminating need for bull-gear shaft and its bearing. Supporting rings with outer surfaces meeting at pitch circles react lateral loads. Intended primarily for application in helicopter in which bull gear on shaft turning rotor combines driving torques from three or more engines.
