Title:
VIBRATION DAMPING MECHANISM FOR BEARING
Document Type and Number:
WIPO Patent Application WO/2006/018915
Kind Code:
A1
Abstract:
A squeeze film damper bearing easily manufacturable, having excellent productivity, and reduced in size and a vibration damping mechanism for the rolling bearing capable of having an effect on loads in two of radial and thrust directions. In the vibration damping mechanism (1) for the rolling bearing, a storage hole (16) having a diameter larger than the diameter of the outer periphery (14) of the bearing is formed on the inside of a housing (15) and an oil supply hole (19) supplying an oil into the storage hole is formed in the wall of the housing (15), the bearing is inserted into the storage hole to form an annular clearance (18) on the outer periphery of the bearing, and a thin flat plate (17) having a plurality of slits is inserted into the annular clearance along the circumferential direction. The portions of the thin flat plate held by the slits are formed in an elastic beam to elastically support the bearing at a center position, and the vibration of the bearing is damped by a squeeze film action caused by an oil film generated by supplying the oil into the annular clearance.
