FIELD: mechanical engineering.
SUBSTANCE: invention can be used in holography, aviation, spacecraft and stations to provide accurate turning through preset arbitrary angle, for continuous rotation around horizontal or vertical axle and high-accuracy displacement at high gear ratio and small overall and mass characteristics. Proposed harmonic gear drive contains flexible gear wheel 1 and rigid gear wheel. Flexible gear wheel 1 in place of connection with rigid cylindrical fastening base 3 is made in form of wavy structural element 4 made by cutting at least two radial grooves from inner and outer sides in rigid cylindrical base 3.
EFFECT: improved accuracy owing to elimination of skewing.
