Abstract
Proposed is a strain wave generator for a harmonic reducer, the strain wave generator including: a cam formed with a plurality of segmented cams on a long-diameter side and the same number of segmented cams on a short-diameter side alternately abutted along a circumferential direction, wherein each of the segmented cams on a long-diameter side has an outer circumference surface of a certain cylindrical surface of a small radius, each of the segmented cams on a short-diameter side has an outer circumference surface of a certain cylindrical surface of a large radius, and the cylindrical surface of each of the segmented cams on a long-diameter side and the cylindrical surface of each of the segmented cams on a short-diameter side, abutted each other, have a common tangent line at a meeting point thereof.
