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.
Claims9
An improved journal bearing adapted for use in lubricated gear trains under loads sufficient to bend the rotor which is rotatably supported within said bearing comprising:
- a bearing shell;
- a non-resilient babbitt lining supported within said bearing shell and interposed between said bearing shell and said rotor;
- the external surface of said lining being of uniform diameter and in contact with said bearing shell to prevent movement of said lining within said bearing shell;
- a portion of the internal surface of said babbitt lining being contoured under no load in a direction along the axis of said rotor and said bearing to conform more closely to the contour of said rotor under load;
- the slope and length of said contour being adequate to maintain an acceptable minimum lubrication film thickness of said bearing with said rotor over the load profile of said rotor.
