摘要： A balancing weight clip for balancing a rotor assembly of a gas turbine engine which includes a weight portion, and a first flange engaging portion and a second flange engaging portion extending from the weight portion. The weight portion and the first and second flange engaging portions define a flange receiving opening for receiving a flange of a disc of the rotor assembly. The first flange engaging portion is provided with a detent facing the second flange engaging portion and engageable with a mating groove provided on a face of the flange. At least one of the first and second flange engaging portions is elastically deformable so that the first and second flange engaging portions are elastically moveable away from one another to removably receive the flange in the flange receiving opening and engage the detent with the mating groove.
摘要翻译：一种用于平衡包括重物部分的燃气涡轮发动机的转子组件的平衡配重夹，以及从所述重物部分延伸的第一凸缘接合部分和第二凸缘接合部分。重物部分和第一和第二法兰接合部分限定了用于接收转子组件的盘的凸缘的凸缘接收开口。第一凸缘接合部分设置有面向第二凸缘接合部分并且与设置在凸缘的表面上的配合凹槽接合的棘爪。第一和第二凸缘接合部分中的至少一个是可弹性变形的，使得第一和第二凸缘接合部分可以彼此弹性地移动，以可拆卸地容纳法兰接收开口中的凸缘，并且将卡具与配合凹槽接合。

摘要： A retaining ring arrangement is provided for axially holding a component on a rotating component of a gas turbine engine. The retaining ring arrangement comprises a split retaining ring mounted in a circumferential groove defined in a radially outer surface of the rotating component. The inner diameter of the retaining ring is biased inwardly in radial contact with a radially outer facing seat provided on one of the two components to be assembled. An anti-rotation feature is provided at the inner diameter of the retaining ring for restraining the ring against rotation. A sleeve surrounds the retaining ring to limit radial expansion thereof when subject to centrifugal forces during engine operation.
摘要翻译：提供了一种保持环装置，用于将部件轴向保持在燃气涡轮发动机的旋转部件上。保持环装置包括安装在限定在旋转部件的径向外表面中的周向槽中的分割保持环。保持环的内径被向内偏压，以与设置在要组装的两个部件之一上的径向外对的座径向接触。在保持环的内径处设有防旋转特征，用于限制环的旋转。在发动机运行期间，当经受离心力时，套筒围绕保持环以限制其径向膨胀。
