The device has an oil transferring unit transferring oil to rolling elements (16) of a bearing maintained between an inner ring (12) and an outer ring (14). The transferring unit transfers the oil to an annular element (48) mounted on a shaft (10). The annular element comprises jet nozzles (56, 58) oriented for sending jets of the oil toward the rolling elements between the rings. The nozzles are supplied with the oil by slanted or radial conduits (50) of the annular element, where rotation of the shaft carrying the annular element induces supply pressure of the nozzles by centrifugal effects. |
