Summary: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 of a ball screw with frequency ranging from 6 to 20 kHz is investigated to clarify the fundamental characteristics and generating mechanism of this sound. It can be inferred from the case of ball bearings that random waviness on the flank surfaces is the cause of this sound. Thus, the test ball screws made by three flank finishing methods were investigated. The waviness on the flank surfaces and the sound pressure level were measured and analyzed to reveal the relation between the waviness and the sound. From the experimental result and considerations, the fundamental characteristics and generating mechanism of this sound were clarified, and some basic information on the sound reduction of the ball screw was obtained.
