Abstract
A bearing lubrication system includes a lubricant distributor configured to perform a lubrication operation by moving lubricant toward an interior of a housing of a bearing, at least one sensor configured to measure at least one condition of the bearing and to produce a signal indicative of the at least one measured condition and a controller configured to produce a transient detection signal, a signal indicative of a second derivative of the measurement signal, for example, and to determine whether an absolute value of the transient detection signal exceeds a threshold value during a given time period after the lubrication operation and to output a failure signal indicative of a lubrication failure in response to a determination that the absolute value of the transient detection signal does not exceed the threshold value during the given time period. Also a method of operating a bearing lubrication system.
