Abstract

A system includes a plain bearing assembly configured to enable rotation of a shaft about a bearing system axis of the shaft. The plain bearing assembly includes the shaft, a cylindrical intermediate bearing disposed about the shaft, and an external bearing disposed about the intermediate bearing. The plain bearing assembly is configured to facilitate oscillatory motion of the shaft relative to the external bearing such that, when the shaft rotates in a first direction about the bearing system axis, the intermediate bearing rotates about the bearing system axis in the first direction, and when the shaft rotates in a second direction opposite the first direction about the bearing system axis, rotation of the intermediate bearing about the bearing system axis is resisted or prevented.
