发明名称 THRUST BEARING ASSEMBLY
摘要 A thrust bearing assembly comprising a bearing runner and a bearing carrier, the carrier defining a plurality of thrust pad sites annularly around the carrier, with a thrust pad disposed at a site and with the carrier limiting movement of the thrust pad in a direction generally radial to the longitudinal axis of the runner while allowing the thrust pad to move in a direction generally parallel to the longitudinal axis. Though the range of movement is limited, the pads can tilt under load to form a hydrodynamic wedge as is known in the art. An embodiment comprises a bearing runner having a wear resistant face and a bearing carrier defining thrust pad sites disposed annularly around the carrier. In one implementation, at each site, a deflection element (e.g., Belleville washer) is disposed in a cavity and a pad is disposed over the deflection element. The pad can be at least partially disposed within the cavity. The wear resistant face contacts the pad. Another embodiment rigidly connects pads disposed on opposite sides of a stationary bearing carrier. Another embodiment attaches pads to a bearing carrier using pad holder assemblies.
