  • Publication number: 20250052277
    Abstract: A system for bearing lubrication comprises a bearing; a temperature sensor; a pressure sensor; a lubricant reservoir; a bearing lubrication comprising a pump; a lubricant drainage line; an exhaust fan; and a bearing lubrication controller communicatively coupled to the temperature sensor, the pressure sensor, the pump, and the exhaust fan, wherein the bearing lubrication controller is programmed to execute bearing temperature control logic comprising detecting the temperature from the temperature sensor, determining whether the temperature falls outside an upper pre-defined bound of the temperature, increasing the rate of a lubricant supplied from the pump to the bearing, detecting the fluid pressure from the pressure sensor, determining whether the fluid pressure falls outside an upper pre-defined bound of the fluid pressure within the bearing, and increasing the speed of the exhaust fan to increase a pressure differential along the lubricant drainage line from the bearing to the lubricant reservoir.

  • Patent number: 12210340
    Abstract: A method which includes receiving a first signal from a first probe at a first location monitoring a rotating component, wherein the first location defines a cross-sectional plane that is perpendicular to the axis of rotation of the rotating component. The method further includes obtaining a vibration model and generating, by a computer processor, a virtual signal at a second location on the machine, where no second probe is present. The second location is in the same cross-sectional plane as the first location and is angularly offset by an angle from the first location. The method further includes performing a plurality of signal processing techniques based, at least in part, on the first signal and the virtual signal and transmitting a plurality of commands based, at least in part, on results of the plurality of signal processing techniques.
