摘要： A cross-beam helicopter rotor in which the torque tube enveloping the flexible spar is supported in relation thereto by an elastomeric primary snubber which is readily replaceable in the field and which utilizes a snubber retainer plate bonded to the spar with an elastomer layer of selected shape factor so that the retainer plate remains adhered to the spar while accommodating all blade and spar pitch and flapping motions and so that the retainer plate elastomer layer is substantially more durable than the elastomer layers of the primary snubber. This primary snubber may be used in combination with an auxiliary snubber.

摘要： A major design consideration in helicopters is that of compensating for ssses on blades resulting from air forces during blade revolutions. Spinning rotor blades are severely stressed. To some degree conventional articulated helicopter rotor hubs overcome vibration difficulties, but high maintenance is a problem. Hingeless helicopter rotor assemblies, generally employing composite materials, were developed to overcome these obstacles. Such hingeless helicopter rotor assemblies usually include a rigid central hub member, and radial flexbeams rigidly attached to the hub member. Flexbeam rotors do not completely eliminate the dynamic instability difficulty. Even using these designs energy must be absorbed by damping means. The shear principle of damping is utilized in this invention.
摘要翻译：直升机的主要设计考虑是补偿叶片转速期间由空气引起的叶片上的应力。旋转叶片受到严重压力。在某种程度上，传统的铰接式直升机转子毂克服了振动的困难，但高维护是一个问题。通常使用复合材料的无绳直升机转子组件被开发以克服这些障碍。这种无铰链式直升机转子组件通常包括刚性中心轮毂构件和刚性地附接到轮毂构件的径向挠性梁。 Flexbeam转子不能完全消除动态不稳定性难度。即使使用这些设计，能量必须被阻尼装置吸收。在本发明中使用了阻尼的剪切原理。

摘要： A nearly spherical laminated elastomeric bearing has a non-circular latitudinal cross-section to accommodate high torque loads in elastomer bending rather than in shear. The nearly spherical profile of the bearing accommodates tilt primarily in shear. Both inwardly and outwardly extending lobes, or splines, are disclosed. The nearly spherical, lobed bearing is useful for a constant velocity joint.

摘要： Centering and stabilizing against rotation of a helicopter swashplate stationary ring are provided by spokes that are attached between the airframe and the stationary ring. When the swashplate tilts for cyclic control, the spokes bend and twist. When the swashplate translates for collective control, the spokes are required to lengthen and skew with respect to the swashplate. An elastomeric bearing having a cylindrical component to allow for skew and a shear pad to allow for lengthening attaches each spoke to the swashplate. The invention eliminates the need for the ball joint, standpipe and scissors associated with traditional swashplate centering techniques.

摘要： Links (48-50) tangential to the rotorshaft (30) and connected to the inner swashplate ring (38) center the swashplate and restrain it from rotating (in the case of a stationary inner ring) by attachment to gearbox lugs (34-36), or drive it in unison with the rotorshaft (in the case of a rotating inner ring) by attachment to rotorshaft flanges. Spherical (rod-end) bearings (52-54, 56-58) so that the links can accommodate collective and cyclic swashplate attitude changes by moving out of plane.Links (70-72) tangential to the outer swashplate ring (64) and connected thereto and to the airframe (74) perform a similar function in restraining, centering and allowing for collective/cyclic movement of a stationary outer swashplate ring.
