摘要： An abnormal noise detector for detecting abnormal noises produced by a gear unit with an eccentrically mounted gear is disclosed. A first embodiment comprises a microphone placed in the vicinity of a gear unit to be tested, a bandpass filter connected to the microphone which passes only a band of frequencies centered around an integral multiple of the normal fundamental frequency of the noise produced by the meshing of the gears of the gear unit, an amplitude detector which detects the amplitude of the signal from the bandpass filter, a frequency deviation detector which detects the frequency deviation of the signal from the bandpass filter, and recorders for recording the values of the signals from the amplitude detector and the frequency deviation detector as a function of time. A second embodiment comprises a microphone, a digital frequency analyzer and a central processing unit for determining whether abnormalities exist in the data produced by the digital frequency analyzer.

摘要： An abnormal noise detector for detecting abnormal noises resulting from a marred tooth surface in a gear of a gear unit is disclosed. A first embodiment of a detector comprises a microphone placed in the vicinity of a gear unit to be tested, a bandpass filter for filtering the output of the microphone so as to pass only an integral multiple of the fundamental frequency of noise due to meshing of the gears of the gear unit, a rectifier for rectifying the filtered output from the bandpass filter, a differentiator for differentiating with respect to time the DC output from the rectifier, a waveform shaper for shaping the output from the differentiator into pulses suitable for counting, and a pulse counter for quantifying the pulses in the output from the waveform shaper. A second embodiment comprises a microphone, a digital frequency analyzer, and a data monitoring computer responsive to the digital frequency analyzer for monitoring the output thereof.

摘要： An abnormal noise detector for use in evaluating the quality of automotive gear units or the like is disclosed. The present invention employs a microphone which picks up the noise produced by a gear unit being tested and an adjustable bandpass filter connected to the microphone which passes only those signals from the microphone having a desired frequency, the desired frequency being a function of the rate of rotation of the gear unit. The bandpass filter is controlled by a proportional amplifier responsive to the rate of rotation of the gear unit which at any rate of rotation of the gear unit causes the bandpass filter to pass only the desired frequency. The filtered output from the bandpass filter is applied to an X-Y recorder which automatically plots the sound pressure of the noise having the desired frequency as a function of the rate of rotation of the gear unit or as a function of the desired frequency.
