ABSTRACT:
A liquid-lubricated roll has an annular roller element rotatably supported by anti-friction bearings on an elongated axle which is longitudinally curved. Liquid lubricant for the bearings is supplied to an annular passageway between the roller element and the axle. During rotation of the roller, the liquid forms into a thin annular layer on its inner surface, which is agitated by projections on the axle to produce a lubricating mist.
Barrier rings placed adjacent to the bearings are adapted to permit liquid to flow along the passageway while the roll is rotating, but to block flow of liquid above a selected level when the roll is stationary. This maintains a more uniform longitudinal distribution of liquid within the roll during periods of disuse, so that none of the bearings will be flooded when rotation starts, and a saving in power consumption and bearing life will therefore be realized.
