    • A midlength balanced rotor comprises a rotor assembly for rotation about an axis of rotation defining at least one of an axially extended, radially concentric, centerline borehole; an array of radially or tangentially distributed, axially extended pockets; and a series of radially or tangentially distributed, axially extended slots. At least one balance weight is positioned within at least one of the axially extended, radially concentric, centerline borehole, the array of radially or tangentially distributed, axially extended pockets, or the radially or tangentially distributed, axially extended slots to balance the rotor assembly. Alternatively, at least one balance correcting mass is removed from at least one of the axially extended, radially concentric, centerline borehole, the array of radially or tangentially distributed, axially extended pockets, or the radially or tangentially distributed, axially extended slots to balance the rotor assembly. In addition, a method of midlength balancing a rotor comprises the steps of providing a rotor assembly with at least one of an axially extended, radially concentric, centerline borehole; an array of radially or tangentially distributed, axially extended pockets; and a series of radially or tangentially distributed, axially extended slots; rotating the rotor shaft about an axis of rotation; determining unbalance of the rotor shaft; and adding or removing weight to at least one of said an axially extended, radially concentric, centerline borehole; array of radially or tangentially distributed, axially extended pockets; or series of radially or tangentially distributed, axially extended slots, to balance the rotor shaft.
    • 中长度平衡转子包括转子组件,用于绕限定轴向延伸的径向同心的中心线钻孔中的至少一个的旋转轴线旋转; 径向或切向分布的轴向延伸袋的阵列; 以及一系列径向或切向分布的轴向延伸的槽。 至少一个平衡重定位在轴向延伸的径向同心的中心线钻孔,径向或切向分布的轴向延伸的凹穴阵列或径向或切向分布的轴向延伸的槽中的至少一个中,以平衡转子组件。 或者,至少一个平衡校正块从轴向延伸的径向同心的中心线钻孔,径向或切向分布的轴向延伸的凹穴阵列或径向或切向分布的轴向延伸的槽中的至少一个上移除,以平衡 转子总成。 此外,中等长度平衡转子的方法包括以下步骤:提供具有轴向延伸的径向同心的中心线钻孔中的至少一个的转子组件; 径向或切向分布的轴向延伸袋的阵列; 以及一系列径向或切向分布的轴向延伸的槽; 围绕旋转轴旋转转子轴; 确定转子轴的不平衡; 以及向所述轴向延伸的径向同心的中心线钻孔中的至少一个加入或移除重物; 径向或切向分布的轴向延伸袋的阵列; 或一系列径向或切向分布的轴向延伸的槽,以平衡转子轴。
