Latest Patents

Fujikawa holds a patent for a "Squeeze Film Damper, Bearing Unit, and Turbine." This invention features a squeeze film damper that includes a bearing housing as an inner ring, which is disposed around the radially outer side of a bearing that rotatably supports a rotary shaft. The design incorporates an outer ring around the bearing housing, with a squeeze film formed by circulating a viscous fluid through a clearance in a radial direction between the two components. Additionally, a coupling pin connects the bearing housing and the outer ring, allowing for deformation in response to relative displacement in the radial direction. The coupling pin is designed with stiffness that is higher in a vertical direction than in a horizontal direction in a cross-section perpendicular to the axial direction of the rotary shaft.
