An investigation of sound generated from a two-step reduction gearbox was carried out in order to obtain basic information for the reduction of sound. Four test casings having different rigidity were prepared. The rigidity was varied by material and thickness of the casing. Casing material was cast iron and aluminum cast. Furthermore, test gears having an accuracy of Class JIS 1, tooth profile error, and pitch error were used. The experiments were carried out to put one of these test gears in the gearbox for each one. The gearbox was driven with and without load, and the sound generated was picked up by a condenser microphone. Using the signal thus obtained, sound pressure level measurement, real time frequency analysis, and sound waveform observation, etc., were carried out. From the experimental results and considerations, the fundamental characteristics of the sound of a gearbox having different casing rigidity were clarified, and some basic information for reduction of sound generated from gearboxes was obtained.
