<P>PROBLEM TO BE SOLVED: To inhibit the sealing performance and service life deterioration of a rolling bearing by changing the flowing direction of lubricating oil discharged between a rolling element and a sealing device of the rolling bearing to prevent the lubricating oil from splashing directly on the sealing device, and to promote the circulation of the lubricating oil by guiding the lubricating oil to an oil discharge hole. <P>SOLUTION: The rolling bearing includes a second inner ring 34, an outer ring 36, the rolling element 62, a second cage 42, and the sealing device 38. The lubricating oil L is supplied from one axial side of the second inner ring 34, and the lubricating oil L is discharged from the oil discharge hole 36e formed closer to the other axial side than a second outer ring raceway 36b of the outer ring 36. Closer to one axial side than the sealing device 38, a shielding plate 48 is further provided between the second inner ring 34 and the outer ring 36. The shielding plate 48 is mounted at the end on the other axial side of a column part 46 of the second cage 42, and the shielding plate 48 is overlapped with the oil discharge hole 36e in the radial direction or located closer to the other axial side than the oil discharge hole 36e. <P>COPYRIGHT: (C)2012,JPO&INPIT |
