抄録
Acoustic behaviour of a pair of gears, of 156 teeth with 2mm module, is investigated by means of acoustical holography which is capable of indicating the location and the intensity distribution of sound sources. Several improvements on the system have been performed for the practical measurements, such as applying two hologram planes and a complex hologram. The sound of tooth contact frequency (7.88 kHz) is radiated strongly from the meshing point in the meshing direction with about 100 times greater power than that in the axial direction. Natural vibrations of the gear wheel occur in any conditions, and rotate together with the gear. The sound is produced according to the vibration from a spatially fixed viewpoint, thus the vibration causes two frequency sounds around the natural frequency instead of itself.
