摘要

The bearing is mounted between two concentric crown wheels (2,3) which delimit an annular space enclosing the bearing and closed by sealing joints. A lubrication conduit is provided between the periphery of one of the crown wheels and the annular space and is connected to a corresponding lubrication reservoir. The moving crown wheel (3) is subjected to asymmetrical forces directed towards a region of the fixed crown wheel. At least one conduit discharges into the annular space in a high pressure angular sector (11) surrounding the region. The corresponding reservoir (5) receives the lubricant coming from the annular space through the conduit under the effect of the high pressure in the annular space.
