摘要： A rotor body rotates about an axis of rotation. A ledge provides a holding structure for holding blades. A plurality of blades are positioned beneath the ledge, load slot is sized to allow a mount portion of the blades to be moved radially inwardly of the ledge. The blades are moved circumferentially to have the mounted structure radially inwardly of the ledge. A lock slot is positioned on one circumferential side of the load slot. The lock slot is formed to receive a lock, and the lock is partially received within a portion of at least one of the blades, to lock the blades within the rotor, and a shield slot on a second circumferential side of the load slot. The shield slot is sized to be different from the lock slot such that a lock cannot be inadvertently positioned within the shield slot.
摘要翻译：转子体围绕旋转轴线旋转。壁架提供了用于保持叶片的保持结构。多个叶片定位在壁架下方，负载槽的尺寸被设计成允许叶片的安装部分在壁架的径向内部移动。叶片沿周向移动以使凸缘的径向向内具有安装结构。锁槽位于装载槽的一个圆周侧。锁槽形成为接收锁，并且锁部分地容纳在至少一个叶片的一部分内，以将叶片锁定在转子内，以及在装载槽的第二周向侧上的屏蔽槽。屏蔽槽的尺寸与锁定槽的尺寸不同，使得锁不能无意中定位在屏蔽槽内。
