摘要： A self-adjusting seal (34, 134) for sealing a joint (22). The joint includes a support member (26), a mis-alignable component (24), and a changeable gap between the support member and the mis-alignable component. The seal includes a first part (36) having a generally annular configuration formed of a resiliently crushable material and defining a planar outer seal face (48) to statically seal to the support member and a first seal part opening (40) extending therethrough. A second seal part (38) axially adjoins the first part. The second seal part has a generally annular configuration formed of a rigid material and a second seal part opening (60) extending therethrough in axial alignment with the first seal part opening. The first and second seal part openings define a non-rotation feature (42) to prevent rotation of the seal on the support member, the second seal part defining a planer inner seal face (56) configured to dynamically and sealingly interface with the mis-alignable component.

摘要： A spring seal (180) for a joint assembly (150) pivotally joining a lever arm (128) to a machine frame (106) includes an annular body (200) having a W-shaped cross section. The W-shaped cross section includes a first cantilevered arm (220), a parallel and spaced apart second cantilevered arm (222), and a spring leg (230) joining the first and second cantilevered arms (220, 222). The spring seal (230) is disposed between a bearing surface (172) on the lever arm (128) and a lug (160) on the frame (106). The W-shaped cross section of the spring seal (180) can collapse and relax to accommodate movement between the lever arm (128) and the frame lug (160). A second spring seal (182) can be disposed between a second bearing surface (176) on the lever arm (128) and a second frame lug (162) opposite the first lug (160).
