Abstract:

An improved journal bearing for use in lubricated gear trains under loads sufficient to bend the rotor of the gear which is rotatably supported in the bearing is provided which utilizes a contoured babbitt lining between the bearing shell and rotor, a portion of the babbitt being contoured in a direction along the axis of the rotor to substantially conform to the contour of the rotor under load with the slope and length of the contour being adequate to maintain an acceptable minimum lubrication film thickness of the bearing with the rotor over the load profile of the rotor.
