ABSTRACT:
A centrifugal trap for preventing solid particles such as sand from reaching water lubricated bearings. The ambient water which is used for lubricating a bearing is passed through a maze structure which includes a first longitudinal annular channel which is substantially concentric with the shaft supported by the bearing, and a second lateral annular channel which is also concentric with the shaft, into a longitudinal annular separating chamber. A centrifugal force is generated in the liquid by rotating a cylindrical member forming one of the walls of the channels and the chamber, which causes sand particles and the like to be driven outwardly against the longitudinal portions of the walls. The liquid, the particles having been separated therefrom, is passed from the centrifugal separating chamber through an inner longitudinal annular channel, which is concentric with the shaft, to the shaft bearing.
