The invention relates to a strain wave gear, having an outer ring with an inner toothing, with which a flexible inner ring with an outer toothing engages at two opposing points. The strain wave gear is characterized in that the ratio of the pitch diameter of the outer ring to the rim thickness of the outer ring lies in the region of 13 to 21, especially in the region of 17 to 19, especially at 17.587, wherein the teeth of the toothing of the inner ring have a profile angle in the region of 8 degrees to 15 degrees or in the region of 11 degrees to 12 degrees or one of 11.615 degrees, and/or wherein the teeth of the toothing of the outer ring have a profile angle in the region of 8 degrees to 15 degrees or in the region of 11 degrees to 13 degrees or one of 12.474 degrees.
