  • Patent number: 4297907
    Abstract: In a gear drive for drivingly connecting two rotatable shafts the transmitted power and torque is split between two parallel paths to reduce the size and required power handling capacity of the gears and other components. The power and torque is divided between the two paths by an axially shiftable torque distributing member carrying two gears each meshing with a respective one of two other gears each comprising part of a respective one of the two parallel power paths. The torque distributing member is rotatably supported relative to the frame or casing of the drive by a bearing surrounding and engaging the member itself. This accurately locates and fixes the axis of rotation of the member and reduces the bearing requirements for its associated shaft.
