In this research, we discuss about the peculiar vibration behavior of a helical gear pair that appears at non-integer order of the meshing frequency. It is supposed that the vibration is generated because of the irregularity of tooth surface form having different cycles of transmission error from tooth mesh cycle. But, it is difficult to detect the slight irregularity with direct measurement of tooth shapes. Characteristics of tooth surface irregularity are discussed with spectra of gear vibration supposing the tooth form deviation that has an integer order component of gear rotation excepting the tooth number order and its harmonics. And analytical model of the mechanism that generates non-integer order vibration are verified experimentally. Possibility of the spectrum analysis of measured tooth surface form irregularity is also discussed.
