Abstract:
In a bearing device, a squeeze film damper includes an annular oil chamber forming an oil film between an outer periphery of an outer race and an inner periphery of a bearing retaining member. A film thickness adjustment portion adjusting a film thickness of the oil film is provided in at least one location in a peripheral direction of the oil chamber. Therefore, it is possible, by changing a distribution in a peripheral direction of dynamic characteristics of the oil film of the squeeze film damper with a simple structure to thus freely adjust a forward mode tendency or a backward mode tendency for centrifugal whirling, to enhance damping performance of the squeeze film damper. Accordingly, centrifugal whirling of a rotating shaft is suppressed effectively by the squeeze film damper with a simple structure.

Claim (Index 2):
The bearing device according to  claim 1 , wherein the film thickness adjustment portion is a recess portion formed in the inner periphery of the bearing retaining member.
