Abstract
An internal gear and cap assembly includes a gear having a base that extends about an axis between a first and second end. The first end defines a groove that extends to a floor and the groove surrounds the axis. Teeth extend from the base. A lip extends from the first end and also surrounds the axis. A cap has a flange that is inserted into the groove. The lip is deformed toward the groove such that material from the lip flows to trap the flange between the lip and the floor of the groove to retain the cap to the gear in the axial direction. Slots may be defined in the flange such that the material from the lip flows into the slots to provide a key-lock between the cap and the gear to prevent rotation of the cap relative to the gear about the axis.
