Abstract: The present invention relates to an improved vibration cancellation device designed to overcome many of the shortcomings inherent in prior devices. In many embodiments, the vibration cancellation device is smaller in scale than prior designs, facilitating more versatility with respect to design options. The device of the present invention achieves a smaller size partly due to the use of suspension springs having an offset, rather than a parallel arrangement.

Abstract translation: 本发明涉及一种设计用于克服现有设备中固有的许多缺点的改进的减振装置。 在许多实施例中，振动消除装置的尺寸比现有设计小，有助于相对于设计选项的更多的多功能性。 本发明的装置部分地由于使用具有偏移而不是平行布置的悬架弹簧而实现较小的尺寸。

Abstract: A torque coupling for a rotor head of a rotary-wing aircraft is configured for rotation with a mast and for causing rotation of an attached yoke. The coupling has trunnions that rotate with the mast and extend generally radially. Pad-bearing assemblies each have a central member coupled to one of the trunnions with a laminated spherical bearing and have laminated pad bearings affixed to opposing sides of the central member. The laminated bearings have alternating rigid and elastomeric layers. A bearing mount is affixed to each pad bearing and is connected to a yoke for rotating the yoke with the mast. The pad-bearing assemblies allow for relative motion between each central member and the associated trunnion and between each central member and the bearing mounts through elastic shear deformation, and this allows for gimballing of the attached yoke relative to the mast.

Abstract: An assembly for providing flexure to a blade of a rotary blade system includes an upper support plate having an upper curved surface, a lower support plate having a lower curved surface, and a yoke positioned therebetween. At least one of the upper and lower yoke surfaces has a layer of cushioning material positioned thereon and secured thereto. An alternate embodiment includes an assembly for providing flexure to a blade of a rotary blade system, including, an upper support plate having an upper curved surface, a lower support plate having a lower curved surface, and a yoke positioned therebetween and directly contacting the support plates wherein one of the curved surfaces is a non-circular arc that does not form part of the circumference of a circle. Another alternate embodiment includes a similar assembly having a twist-shank type of yoke for providing rotation of attached blades about their respective pitch axes.

Abstract: The present invention relates to an improved vibration cancellation device (10) designed to overcome many of the shortcomings inherent in prior devices. In many embodiments, the vibration cancellation device (10) is smaller in scale than prior designs, facilitating more versatility with respect to design options. The device of the present invention achieves a smaller size partly due to the use of suspension springs (32) having an offset, rather than a parallel arrangement.
