Sometimes, peculiar vibration of a helical gear pair that appears at non-integer order of the mesh frequency becomes predominant component even on a ground gear. It is because of the irregularity of tooth surface form having different cycles of transmission error from tooth mesh cycle and is called as 'ghost noise' [2]. But, it is difficult to detect ghost noise with a measured tooth profile because there are few cycles of the undulation on a measured tooth trace. In this research, we measured two-dimensional surface forms of all teeth of a helical gear. With this detailed tooth surface measurement result, we discuss about how to detect surface undulation which generate ghost noise. Because the frequency resolution of Fourier analysis become worse when measured tooth number is a few, we discuss about the effectivity of applying Maximum Entropy Method comparing with Fourier analysis.
