Method and apparatus for monitoring of the wear on a shaft bearing

摘要

Apparatus monitors the wear of a propeller shaft bearing such as may be found in a tanker, or any other ship, while it is in service. As the shaft is rotating a sensor provides a signal corresponding to the displacement of the shaft with respect to its longitudinal axis. The displacement signal is applied to an averaging network which provides a signal corresponding to the average displacement to a recorder. The recording of the average displacement signal permits determination of wear of the shaft bearing.
