Abstract
A construction for locking the hub of a gear or other means to a shaft. The shaft is cylindrical but is cut away to form a flat surface parallel to the axis of the hub. A wedge has a portion which fills the cavity between the cylindrical inside surface of the hub and the flat surface on the shaft. An integral lug portion of the wedge extends radially outwardly into a slot in the hub so as to prevent the hub from turning with respect to the wedge. The wedge is prevented from turning with respect to the shaft by its flat bottom surface which is coextensive with the flat surface on the shaft. That provides a driving relationship between the hub and the shaft. The driving relationship between the wedge and the hub is through side surfaces of the cavity in the hub and the lug portion of the wedge.
