ROLLING BEARING DEVICE HAVING A HYDRAULIC DAMPING DEVICE

摘要

A roller bearing device in particular in a turbocharger having a housing component having a bearing hole having an inner circumference and a rolling bearing received therein on an outer race having an outer circumference. In order to implement a component such as a rotor assembly of a turbocharger that can rotate on the inner circumference with great smoothness and that is protected against imbalance, a hydraulic damping device made of reservoirs filled with a hydraulic fluid and alternating along the circumference facing the outer periphery and the inner periphery is provided in an annular gap between the outer periphery of the outer race and the inner periphery of the bearing hole by radially pretensioning the outer race relative to the bearing hole.
