  • Patent number: 8171797
    Abstract: Disclosed is a method for assessing deterioration in a gearbox. Data is obtained from an operating gearbox regarding harmonic frequencies and their related sidebands generated as a consequence of the gearbox operation. In a first embodiment, a Sideband Energy Ratio (SER) is calculated by dividing the amplitude of the sum of sideband signals associated with a harmonic to the amplitude of the harmonic. In a second embodiment, a SER is calculated based on sideband amplitudes associated with adjacent harmonics. The ratio may be monitored over time or compared to one or more values to provide an indication of deterioration.

  • Publication number: 20100256927
    Abstract: A method estimates closure of a suction valve. A number of samples are received, each including a reference and a pressure reading. Data points are determined from the samples, each including a reference and a pressure indicator. The reference indicator directly correlates to the reference reading, and the pressure indicator correlates to an average of pressure readings collected about the sample. The data points include a suction data point, a discharge data point, and an index data point. A best-fit linear equation representing data points from about the index data point to about the discharge data point is determined. A half-slope linear equation is also determined, which has half the slope of the best-fit linear equation and the index data point as one solution.
