Description

Technical Field

[0001] The utility model relates to the technical field of thrust bearings, in particular to an active water-lubricated thrust bearing. Background Art

[0002] Thrust bearings are special bearings used to bear axial forces, that is, bearings that bear forces in a direction parallel to the axis. Water-lubricated thrust bearings use water as the lubricating medium for mechanical transmission friction pairs. They are superior to oil in many aspects and have broad application prospects.
