BEARING DEVICE FOR SUPERCHARGER

WIPO Patent Application WO/2018/070311

A1

The present invention addresses the problem of providing a bearing device (10) for a supercharger (1) in which a discharging path for a lubrication oil supplied to an oil film damper (8) has a path in which the lubrication oil passes through rolling bearings (11, 12) and is discharged to the outside in the axial direction, and a path in which the lubrication oil is discharged from both end surfaces of a holder (20), and the lubrication oil passing through the rolling bearings (11, 12) and discharged to the outside in the axial direction, and the lubrication oil discharged from both end surfaces of the holder (20) are prevented from colliding with each other in an outside portion in the axial direction. By providing, outside the outer races (11b, 12b) in the axial direction, a flow direction changing part (40), which changes the flow direction of lubrication oil discharged from the path of both end surfaces of the holder (20) in the axial direction toward the outside of outer races (11b, 12b) in the axial direction, and thus the lubrication oil discharged from both end surfaces of the holder (20) has been prevented from colliding together in the outside portion of the rolling bearings (11, 12) in the axial direction.
