Abstract
A transverse flow fan rotor for the cleaning and separating system of a combine harvester and for other uses features a lightweight yet sturdy rotor structure which eliminates the need for machined shaft keyways, keys, set screws and pins for attaching rotor discs to a drive shaft. The discs are frictionally clamped to the shaft by the action of split tapered lock bushings and coacting opposing collars on opposite sides of each disc drawn together by bolts.
