An investigation of sound generated from a ball screw was carried out in order to obtain basic information for the sound reduction of a ball screw. The test ball screws were of the single nut and single guide-tube type. Their screw shaft diameter was 20 mm and their lead was 10 mm in length. Test ball screws were set up at a ball screw sound testing machine installed in a soundproof room, and they were operated by the testing machine under the non-load condition. The sound generated from the ball screw was picked up by a condenser microphone. Using the signal thus obtained, sound pressure level measurement, sound waveform observation and real time frequency analysis etc. were carried out. From the experimental results and considerations, the fundamental sound characteristics of a ball screw were clarified, and some basic information concerning the sound reduction of a ball screw was obtained.
