  • Patent number: 9605712
    Abstract: A journal bearing for supporting a rotor shaft extending along a rotor axis having a support element, and at least two pads for supporting the rotor shaft, wherein the pads are supported by the support element is provided herein. The pads may include a bearing surface, wherein the support element and pads include a support for each pad. The support for each pad may include structure to enable tilting for each pad around a tilt axis extending parallel to the rotor axis. The journal bearing may be assigned to a specific default rotation direction of the rotor shaft, wherein tilting of the pad into the rotation direction is positive tilting and tilting of the pad versus the rotation direction is negative tilting.
    Type: Grant

The pads may include a bearing surface, wherein the support element and pads include a support for each pad. The support for each pad may include means to enable tilting for each pad around a tilt axis extending parallel to the rotor axis. The journal bearing may be assigned to a specific default rotation direction of the rotor shaft, wherein tilting of the pad into the rotation direction is positive tilting and tilting of the pad versus the rotation direction is negative tilting.

  • Patent number: 5244285
    Abstract: Squeeze film damper with a viscous damping agent between two concentric cylindrical surfaces (5) on the internal (3) and external (6) parts, respectively, of the damper. The clearance between these two surfaces (5) is supplied with a viscous damping agent, usually oil, from a groove (4) in the cylindrical surface on the internal part (3) of the damper. This groove (4) does not extend all around. In the lower part of the internal part (3) of the damper there are instead two pockets (7) which are separated from each other and from the long damper oil groove (4). When these two pockets (7) are supplied through channels (8) with oil of an adjusted pressure, a lifting force arises which acts on the internal part (3) of the damper so that this part and the associated shaft (1) are lifted and centered, whereupon during operation a damper clearance, extending all around, is obtained without mechanical means.
