Jan 01, 1989 This note presents an investigation into the problems of ball mill pinions. Pinion pitch measurements and vibration analysis were conducted to find a relationship between vibration signals and the errors. Analysis of time synchronous averaging TSA indicates the teeth with pitch error.

This paper details analyses of condition indicator performance for the helicopter nose gearbox within the U.S. Armys Condition-Based Maintenance Program. Ten nose gearbox data sets underwent two specific analyses. A mean condition indicator level analysis was performed where condition indicator performance was based on a batting average measured before and after part replacement. Two ...

QUANTIFYING BEARING FAULT SEVERITY USING TIME

The technique is based on analyzing the jerk energy gradient of the synchronously averaged fault impact. The averaged signal is extracted by using time synchronous averaging TSA trig- gered by the fault race frequency FRF for the detection task and triggered by shaft speed for the quantifying task.
