An investigation of sound generated from a ball screw was carried out in order to obtain basic information on the sound reduction of a ball screw. In this paper, the sound generated from the ball screw, which prevens pulse sound from occurring, is investigated to clarify the fundamental characteristics and generating mechanism of this sound. It can be inferred from the case of ball bearings that the waviness on the flank is a cause of the sound in the case of ball screws. Thus, the test ball screws made by two flank finishing methods were investigated. The waviness on the flank of the screw shaft and the sound pressure level were measured and analyzed to reveal the relation between the sound and the waviness. From the experimental results and considerations, the fundamental characteristics and generating mechanism of the sound caused by the waviness on the flank of the screw shaft were clarified.
