Abstract
The invention relates to a harmonic reduction gear comprising a drive-side eccenter ( ) which engages into a complementary opening ( ) of an outer toothed member ( ), and a housing-fixed inner toothed ring ( ) which is arranged around the outer toothed member ( ) and on which the outer toothed member ( ) rolls with the reversed rotational sense as the eccenter ( ) when the eccenter ( ) is rotated. The invention consists in that the outer toothed member ( ) has only few, preferably only two at least substantially diametrically opposed teeth ( ) of which during rotation of the eccenter ( ) in each case one ( ) is pushed into a tooth depression ( ) of the inner toothed ring ( ) while the other ( ) is lifted out of the inner toothed ring ( ) and is pivoted counter to the rotational sense of the eccenter ( ) to the next tooth depression ( ) into which, during further rotation of the eccenter ( ), the other tooth ( ) is pushed in with the first tooth ( ) being lifted out, and so forth.
