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).
摘要(中):
用于将杠杆臂(128)枢转地连接到机架(106)的接头组件(150)的弹簧密封件(180)包括具有W形横截面的环形体(200)。 W形横截面包括第一悬臂(220),平行和间隔开的第二悬臂(222)和连接第一和第二悬臂(220,222)的弹簧腿(230)。 弹簧密封件(230)设置在杠杆臂(128)上的支承表面(172)和框架(106)上的凸耳(160)之间。 弹簧密封件(180)的W形横截面可以折叠和松弛以适应杠杆臂(128)和框架凸耳(160)之间的运动。 第二弹簧密封件(182)可以设置在杠杆臂(128)上的第二支承表面(176)和与第一凸耳(160)相对的第二框架凸耳(162)之间。
