    摘要: Detecting the occurrence of loss of effective lubrication in high-speed machinery components is provided. The imminent catastrophic failure may be predicted when torque or power transfer is lost. An estimate of when failure will likely occur throughout the operation of the machinery may be determined as well as the damage state after the liquid lubrication supply has ended or becomes inadequate to lubricate the machinery components effectively. By monitoring the concentration of gas species and the rate of change in concentration of the gas in the gearbox or machinery enclosure after the supply of the primary lubricant ends, determinations may be made about the time to failure and the damage state. The determinations may be based on thermomechanical and chemical processes, on measurement of a baseline system, or by setting a threshold of expected change in gas concentration. These determinations may be transmitted for further decision making and response.
