Abstract
A drive sprocket retention system is provided for use in a belt conveyor in which a plurality of drive sprockets are mounted on a rotatable element having an axial keyway formation. The retention system is defined by a key arrangement disposed in the keyway formation of the rotatable element, wherein a recessed portion of a key is received and retained between each drive sprocket and the rotatable element without the need for threaded fasteners. The retention system is movable between a locked position and a release position, wherein the spacing between the drive sprockets is substantially fixed when the retention system is in the locked position, and the drive sprockets are independently movable along the longitudinal length of the rotatable element when the retention system is in the release position.
