Abstract
A gear unit includes a gear having a gear face and a plurality of gear teeth extending outwardly from the gear face. The gear unit also includes a hub integrally formed with the gear and arranged coaxially to the gear. The hub extends outwardly of the gear in a direction of a central axis of the gear. The gear unit also includes an undercut defined at an interface of the gear and the hub and includes a curved portion arranged at proximate to an inner end of the gear. The undercut reduces a stress concentration at the interface of the gear and the hub.
