Patent ID: 7628542

Claim:
A bearing vibration damping mechanism comprising: a bearing; a bearing housing provided with a bearing holding bore having a diameter greater than an outside diameter of the bearing; and a thin, flat sheet provided with a plurality of slits, wherein; the bearing is put in the bearing holding bore so that the bearing may not move axially out of the bearing holding bore and an annular space is formed around the bearing to permit radial movement of the bearing; the thin, flat sheet is inserted into the annular space so as to extend circumferentially, and parts of the thin, flat sheet extending between adjacent slits have opposite ends resting on a side wall of the bearing holding bore and serve as elastic beams in contact with the bearing to support the bearing elastically and to dampen vibration of the bearing; and the bearing housing is provided with an oil hole through which oil is supplied into the bearing holding bore, oil is supplied into the annular space to form an oil film in the annular space.
