Boltless unitary ring gear-flange body

Abstract

Apparatus and associated methods relate to a unitary ring gear-flange body (URGFB). In an illustrative example, the flange body may be spin-formed and may, for example, include a riser body extending substantially parallel to a longitudinal axis and a flange extending substantially radially outward from the riser body. To the riser body may, for example, be welded a ring gear to form a unitary assembly, the ring gear having an axis of revolution aligned with the longitudinal axis. A continuous coating may, for example, be applied to at least a selected portion of a surface of the unitary assembly. Various embodiments may advantageously provide a cost-efficient, weight-efficient, and/or time-efficient unitary body which may, for example, be coupled to machinery to provide a shaftless torque-transmitter.
