Device for electrical conductive connection between e.g. slide bearing and shaft of electric motor, has recesses engaged with slats, and shaft and slide bearing forming circulating gap, which is filled with ionic liquid

摘要

The device has a shaft (2) and a slide bearing (1) forming a circulating gap (3), which is filled with ionic liquid for hydrodynamic lubrication of the slide bearing and having electrical interconnection between the slide bearing and the shaft. The shaft comprises slats (4) in a storage area, and recesses (5) of the slide bearing engage with the slats. The slats and the recesses enlarge an ionic liquid moistened bearing surface. Cations and anions are used for obtaining ionic liquid with high conductivity.
