Abstract:
1. A hydrodynamic liquid metal radial bearing comprising: a rotating shaft; a stationary sleeve with an annular groove; a raised portion on the rotating shaft that extends into the annular groove, the raised portion includes two radials passages and two axial passages that form a first recirculation passage and a second recirculation passage for a liquid metal; a seal formed between the rotating shaft and the stationary sleeve to form a sealed cavity for the liquid metal and to reduce a leakage of the liquid metal; a liquid metal filling the sealed cavity; and the annular groove forming a low pressure reservoir and a high pressure cavity, the high pressure cavity comprising an annular channel formed within the annular groove, an opening of the annular channel faces the two radial passages such that liquid metal discharged from the two radial passages flows into the annular channel.
