A swinging-screw gear comprises a wave master (oscillatory circuit), a screw couple, and has large transmission ratio. Swinging reciprocal motion is formed by rigid unit by means of rack-cam and two beams, and in the next link swinging reciprocal motion is transformed to rotary motion by means of screw mechanism of transformation of reciprocal motion to rotary motion with increased transmission ratio.
