    • An anchorage system is described for a rotor (18) of a rotating fluid machine (10). The rotor (18) has a profile which comprises a first front surface (24) substantially concave and a second rear surface (26) substantially convex, opposite to the first front surface (24). The rotor (18) also has a central portion (28), configured for being constrained with interference on a rotating shaft (14) of the machine (10) and equipped with a shank (30) connected with the second rear surface (26). The system comprises at least one check ring (32) assembled by interference on the shank (30) of the rotor (18). The check ring (32) has a first internal circumferential surface (34), coupled by interference with the shank (30), and a second internal circumferential surface (36), coupled by interference with the shaft (14), to increase the torque which can be transmitted from the shaft (14) to the rotor (18).
    • 对于旋转流体机械(10)的转子(18)描述了锚固系统。 转子(18)具有轮廓,该轮廓包括大致凹入的第一前表面(24)和与第一前表面(24)相对的基本上凸出的第二后表面(26)。 转子(18)还具有中心部分(28),其构造成受到干扰地限制在机器(10)的旋转轴(14)上,并配备有与第二后表面(26)连接的柄(30) 。 该系统包括至少一个通过干涉装配在转子(18)的柄(30)上的止回环(32)。 止回环(32)具有通过与柄(30)的干涉而联接的第一内圆周表面(34)和通过与轴(14)的干涉而联接的第二内圆周表面(36),以增加扭矩 其可以从轴(14)传递到转子(18)。

    • Overhung axial compressor (58), chemical reactor (130) and method for compressing a fluid. The overhung axial compressor (58) includes a casing (60) configured to be vertically split along a vertical axis (72) for access to an inside of the casing (60) and a removable cartridge (62). The removable cartridge (62) is configured to fit inside the casing (60) and to be detachably attached to the casing (60). The removable cartridge (62) includes a shaft (92) disposed along a horizontal axis (74), a bearing system (98) attached to the removable cartridge (62) and configured to rotationally support a first (96) end of the shaft (92), and plural blades (90) disposed toward a second end (94) of the shaft (92) such that the second end (94) is overhung inside the casing (60). The compressor (58) also includes a guide vane mechanism (66) configured to connect to the removable cartridge (62), the guide vane mechanism (66) being configured to adjust a flow of a fluid to the plural blades (90).
    • 悬臂式压缩机(58),化学反应器(130)和压缩流体的方法。 悬臂轴向压缩机(58)包括壳体(60),其构造成沿垂直轴线(72)垂直分开,以便进入壳体(60)的内部和可移除的筒(62)。 所述可移除盒(62)构造成装配在所述壳体(60)内并且可拆卸地附接到所述壳体(60)。 所述可移除盒(62)包括沿着水平轴线(74)设置的轴(92),附接到所述可移除盒(62)的轴承系统(98),并且构造成旋转地支撑所述轴的第一(96)端 92)和朝向轴(92)的第二端(94)设置的多个叶片(90),使得第二端(94)悬挂在壳体(60)内。 压缩机(58)还包括被构造成连接到可移除筒(62)的导叶机构(66),导叶机构(66)构造成调节流体到多个叶片(90)的流动。
