The mechanism of the sideband phenomenon of planetary gear vibration that often occurs in a planetary gear set was clarified in connection with mesh phase differences. This sideband phenomenon is one in which the (z-1) or (z+1) order component level is higher than the mesh order (z) component level. The notation (z-1) or (z+1) means the mesh order (z) minus or plus one carrier revolutioa An in-phase (IP) planetary gear set has no such sideband phenomenoa In a sequentially phased planetary gear set, this phenomenon occurs in transverse and tilting vibratioa Which sideband, either (z-1) or (z+1), occurs depends on the relationship between the mesh phasing direction and carrier rotation directioa We have developed a method of performing a multiple degree-of-freedom vibration analysis of a planetary gear set to verify this sideband phenomenon.
