Pad-type thrust bearing and rotary machine comprising such a thrust bearing

摘要

A pad-type thrust bearing in which each pad rests on a volume of liquid enclosed in a cavity connected to adjacent cavities by ducts. The thrust bearing includes a number of casings, each casing delimiting the cavity and which are connected to one another by ducts. The convex casings and the ducts together form a hollow functional subassembly which is separate from the other constituent components of the thrust bearing and which delimits a liquid-filled closed volume. Each casing includes two half-shells positioned one on each side of a flexible bladder and each duct including a flexible hose inserted in a sheath.

1. A pad-type thrust bearing in which each pad rests on a volume of liquid enclosed in a cavity connected to adjacent cavities by ducts, the thrust bearing comprising several casings, each casing delimiting a respective cavity and connected to one another by ducts, the casings and the ducts together forming a hollow functional subassembly which is separate from the other constituent components of the thrust bearing and which delimits a closed volume filled by the liquid, wherein each casing comprises two identical half-shells positioned one on each side of a flexible bladder and each duct comprises a flexible hose inserted in a sheath.
