Abstract
A radially compliant gear is provided to reduce transmitted shock loads and/or resist jamming as a result of debris entering its mesh with another gear. The radially compliant gear includes a hub adapted to rotate about an axis, and a compliant rim. The hub includes a first surface that faces radially inwardly. The rim includes external gear teeth and a second surface that faces radially outwardly. The rim is mounted to the hub through the first and second surfaces to allow localized radial deflections of the rim relative to the hub. The first and second surfaces are configured to provide a predetermined minimum radial preload between the rim and the hub.
