Abstract: A gyroscopic roll stabilizer includes a gimbal having a support frame and enclosure configured to maintain a below-ambient pressure, a flywheel assembly including a flywheel and flywheel shaft, one or more bearings for rotatably mounting the flywheel inside the enclosure, a motor for rotating the flywheel, and bearing cooling system for cooling one or more bearings supporting the flywheel. The bearing cooling system enables heat generated by the bearings to be transferred through the flywheel shaft to a heat sink disposed within a cavity in the end of the flywheel shaft, and then external to the enclosure.

Abstract: A bearing system is provided that includes a stationary structure, a rotating structure, a magnetic-foil bearing and a cooling jacket. The rotating structure is rotatable about an axis. The magnetic-foil bearing radially supports the rotating structure within the stationary structure. The magnetic-foil bearing includes a magnetic bearing stator, a magnetic bearing rotor and a foil bearing. The foil bearing is disposed radially between the magnetic bearing stator and the magnetic bearing rotor. The cooling jacket circumscribes and radially engages the magnetic bearing stator. A cooling circuit is configured to flow cooling fluid within the cooling jacket to cool the magnetic bearing stator.

Abstract: A method of additively manufacturing a component is provided. The method includes generating a three-dimensional (3D) model of the component, generating a first heat map of the 3D model which is illustrative of first thermal effects the component is expected to experience during additive manufacturing, generating a second heat map of the 3D model which is illustrative of second thermal effects the component is expected to experience during operational use, updating the 3D model to include 3D heat exchange fin models for reducing each of the first and second thermal effects and updating the 3D model with the 3D heat exchange fin models to include 3D weight reduction cavity models for weight-neutralizing the 3D heat exchange fin models.

Abstract: A gyroscopic roll stabilizer for a boat includes an enclosure mounted to a gimbal for rotation about a gimbal axis and configured to maintain a below-ambient pressure, and a flywheel assembly including a flywheel and flywheel shaft, with the flywheel assembly rotatably mounted inside the enclosure for rotation about a flywheel axis. The gyroscopic roll stabilizer also includes a motor operative to rotate the flywheel assembly and disposed inside the enclosure. A motor cooling circuit is configured to transfer heat away from the motor. The motor cooling circuit has a closed fluid pathway for recirculating cooling fluid therein. The fluid pathway includes a fluid channel jointly defined by the motor and the enclosure and having the cooling fluid therein. The gyroscopic roll stabilizer is configured to transfer heat away from the motor to the cooling fluid. Related methods are also disclosed.

Abstract: Provided is a bracket for securing a number of cooling rings arranged on a bearing ring, which bracket includes an upper surface, a lower surface shaped to lie on the cooling rings, and a through-opening extending between the upper surface and the lower surface to accommodate a fastener for mounting the bracket to the bearing ring; wherein the material properties of the bracket are chosen to permit movement of the cooling rings relative to the bracket when the bracket is mounted to the bearing ring; and/or wherein the bracket is made of a resilient elastic material. Further provided is a cooling arrangement for a bearing, including a number of cooling rings arranged in parallel on a mounting surface of a bearing ring of the bearing; and a number of such brackets to secure the cooling rings to the bearing body.
