Patent number: 10569867Abstract: A hub system comprises at least one yoke, at least one shear bearing, and at least one mast adapter. The at least one mast adapter is configured to support the at least one yoke and the at least one shear bearing, and the at least one yoke has a flapping hinge that is non-coincident with a flapping hinge of the at least one shear bearing. Another hub system comprises a stacked yoke and a mast adapter. The mast adapter is configured to transfer rotation from a rotor mast to the hub system to rotate the hub system about a central axis of rotation. The mast adapter is further configured to support the stacked yoke such that each yoke in the stacked yoke is configured to accommodate at least some amount of rotation about an axis that is perpendicular to or about perpendicular to the central axis of rotation.Type: GrantFiled: August 10, 2018Date of Patent: February 25, 2020Assignee: BELL HELICOPTER TEXTRON INC.Inventors: Andrew Maresh, Frank Bradley Stamps, Patrick Ryan Tisdale, Robert Patrick Wardlaw, Andrew Haldeman, Drew Alan Sutton
