Abstract
A monolithic transmission gear produced through additive manufacturing. The transmission gear includes a central hub defining a rotation axis, an outer ring including a plurality of gear teeth spaced circumferentially about the outer ring, and a web interconnecting the central hub to the outer ring. The web including a plurality of radial springs extending between the central hub and the outer ring. The radial springs being radially stiff to center the outer ring about the central hub and being torsionally resilient to permit relative rotation between the outer ring and the central hub.

A monolithic transmission gear produced through additive manufacturing, the transmission gear comprising:
- a central hub defining a rotation axis;
- an outer ring including a plurality of gear teeth spaced circumferentially about the outer ring;
- and
- a web interconnecting the central hub to the outer ring, the web including a plurality of radial springs extending between the central hub and the outer ring, the radial springs being radially stiff to center the outer ring about the central hub and being torsionally resilient to permit relative rotation between the outer ring and the central hub.
