Abstract

A harmonic drive is provided that comprises a wave generator, a flexible, externally toothed gear element that can be deformed by said wave generator, and at least one internally toothed gear component which meshes with the flexible, externally toothed gear element. The externally toothed element has, with respect to its mechanically unloaded state, a non-circular shape that deviates from an elliptical shape.
