Debris detector for non-ferrous bearings

摘要

A system (301) and method to detect non-ferrous debris from a non-ferrous roller bearing element, such as used for lubricating the rotor system of an aircraft . The system (301) includes a trap (303) in fluid communication with a lubrication fluid of the non-ferrous bearing and a sensor (307) operably associated with the trap (303). The method includes trapping the non-ferrous material debris in the lubrication fluid with the trap (303) and triggering the sensor (307) upon detection of the non-ferrous material debris trapped within the trap (303). Changes in the pressure of the lubrication fluid are compensated by balancing the force undergone by the trap with a force applied to a compensator linked mechanically to the trap and having an orifice whose size can be adjusted based on lubricant pressure.
