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 1):
A bearing device comprising an inner race fitted around an outer periphery of a rotating shaft, an outer race supported on an inner periphery of a bearing retaining member via a squeeze film damper, and a plurality of rolling bodies disposed between the inner race and the outer race,\n the squeeze film damper comprising an annular oil chamber forming an oil film between an outer periphery of the outer race and the inner periphery of the bearing retaining member, and a film thickness adjustment portion adjusting a film thickness of the oil film being provided in at least one location in a peripheral direction of the oil chamber.
