Abstract:
A harmonic drive (12), having a non-round drive core which is rotatable around an axis (24) arranged therein as a wave generator (14), and an internal geared wheel (15), revolvingly radially deformable by tappets (21), having low-friction implementation of a radial support of the tappet (21) against the wave generator (14),characterized in that the tappets (21) are movably connected to one another peripherally via flexible arms (28-28) connected to their shafts (22), the tappets (21) are dimensionally stable under heat at the respective feet (23) of their shafts (22) and are tipped or coated to be low-friction in relation to the wave generator lateral surface (40), and the heads (26) have insides which have a film wall (43) stretched at least partially over them transverse to the device axis (24).
