US 2026/0226909 A1 · EDM ADJUSTABLE EVACUATED FLEX PIVOT BEARING

Abstract

A compressor system includes an electrical discharge machined (EDM) bearing configured to support a load of a rotating shaft. The EDM bearing includes a housing extending around a rotational axis. The EDM bearing includes an EDM flexing pivot pad machined from the housing, where the EDM flexing pivot pad is configured to provide support to the rotating shaft rotating around the rotational axis. The EDM flexing pivot pad includes a lubricant channel aligned with the lubricant opening and a lubricant nozzle removably coupled to the lubricant channel and disposed proximate to the EDM flexing pivot pad. The lubricant nozzle is configured to deliver a lubricant flow from the lubricant port directly to the rotating shaft.
