摘要

The harmonic drive has a coaxially arranged non-circular core (7), where an external annular gear (3) is provided with a cylindrical inner surface, an inner teething (2) and an elastically deformable intermediate annular gear (5). The intermediate annular gear is formed by a standard plastic molded part with a base surface (14) on one side. A plastic housing (1) or a housing part is arranged laterally to an axis (8) of the harmonic drive on the other side.
