Abstract: An elastomeric spring-damper has a one-piece tubular body having an integral cap. A tension stop flange is formed in the body near the cap portion, and a compression stop flange opposing the tension stop flange is formed on the cap portion. An inner member located within the body is coupled to the body with an annular elastomeric member, such that longitudinal motion of the inner member relative to the body is allowed through elastic deformation of the elastomeric member. An inner member stop flange is positioned between the compression stop flange and the tension stop flange to limit longitudinal motion of the inner member relative to the body.

Abstract translation: 弹性弹簧阻尼器具有一体式管状体，其具有整体盖。 在盖部附近形成有张紧止动凸缘，并且在盖部上形成有与张力停止凸缘相对的压缩止挡凸缘。 位于主体内部的内部构件与环形弹性构件联接到主体，使得内部构件相对于主体的纵向运动允许弹性体构件的弹性变形。 内部构件止动凸缘位于压缩止动凸缘和张力止动凸缘之间，以限制内部构件相对于主体的纵向运动。

Abstract: An assembly for providing flexure to a blade of a rotary blade system, the assembly including an upper support plate (22) having an upper curved surface (37) , a lower support plate (24) having a lower curved surface (37) , and a yoke (120) positioned therebetween. At least one of the upper and lower yoke surfaces (37) having a layer of cushioning material (56) positioned thereon and secured thereto. The layer of cushioning material (56) extending along and following the general contour of yoke surface (37) , and the layer of cushioning material (56) directly contacting a support plate (22,24) . Another embodiment is an assembly for providing flexure to a blade of a rotary blade system, including, an upper support plate (22) having an upper curved surface (27) , a lower support plate (24) having a lower curved surface (37) , and a yoke (120) positioned therebetween and directly contacting the support plates wherein one of the curved surfaces (37) is a non-circular arc that does not form part of the circumference of a circle.
