    • A momentum free bearing assembly (400, 600) for use in orthotic and prosthetic devices and a prosthetic knee (100) incorporating the same are disclosed. The bearing assembly (400, 600) includes an engaging ring (422, 622) having a swivel portion (424, 624) received within the engaging ring (422, 622). The engaging ring (422, 622) is received within a bore (320, 720) in a mount. Retainer rings (410, 610) may be placed on either side of the engaging ring (422, 622) within the bore (320, 720) to retain the engaging ring (422, 622) within the mount. Seals (430, 630) having sealing members (434, 634) may be provided on either side of the engaging ring (422, 622) to seal the engaging ring (422, 622) within the mount. A cylindrical rod (310, 710) engages the swivel portion (424, 624) and the seal (430, 630) through bores (436, 636; 426, 626) provided in each of the seal (430, 630) and the swivel portion (424, 624). The ends of the cylindrical rod can be press-fit within bores (220, 820) on a mount and a frame (110) of a prosthetic knee (100).
    • 公开了用于矫形器和假体装置中的无动量轴承组件(400,600)和包含其的假肢膝盖(100)。 轴承组件(400,600)包括具有容纳在接合环(422,622)内的旋转部分(424,624)的接合环(422,622)。 接合环(422,622)容纳在安装座中的孔(320,720)内。 可在孔(320,720)内的接合环(422,622)的任一侧上放置保持环(410,610),以将接合环(422,622)保持在安装座内。 具有密封构件(434,634)的密封件(430,630)可以设置在接合环(422,622)的任一侧上以将接合环(422,622)密封在安装座内。 圆柱形杆(310,710)通过设置在每个密封件(430,630)和转环中的孔(436,636; 426,626)接合旋转部分(424,624)和密封件(430,630) 部分(424,624)。 圆柱形杆的端部可以压配合在假肢膝盖(100)的支架和框架(110)上的孔(220,820)内。
