Abstract
A bearing monitor has a bearing sensor to monitor frequencies emitted by a bearing in a rotating component. The bearing sensor has an output to a processor. The processor is attached to the rotating component to process the output from the bearing sensor to a digital or logical signal, which may include determining if the output indicates that the bearing requires service.
Claims24
A bearing monitor comprising:
- a bearing sensor to monitor frequencies emitted by a bearing in a rotating component, the bearing sensor having an output;
- and
- a processor attached to and rotating with the rotating component to process the output from the bearing sensor and to convert the output into a digital or logical signal correlating to a condition of the bearing.
A method of monitoring a bearing comprising the steps of:
- sensing vibrations emitted by a bearing using a sensor attached to a rotating component, the bearing sensor having an output;
- and
- providing a processor attached to and rotating with the rotating component to process the output from the bearing sensor to a digital or logical signal correlating to a bearing condition.
A system to monitor a bearing in a rotating component comprising:
- a bearing sensor attached to the rotating component to monitor frequencies emitted by the bearing in the rotating component, the bearing sensor having an output;
- and
- a processor attached to and rotating with the rotating component to process the output from the bearing sensor and to convert the output into a digital or logical signal correlating to a condition of the bearing.
