    Abstract: A centrifugal separator is configured for processing a product by separating a relatively heavy component and a relatively light component therefrom. The centrifugal separator comprises a spindle (3) supported by a stationary frame (2). A drive unit (4) acts on a rotating member (5) mounted on the spindle to rotate the spindle. A centrifuge rotor (8) mounted to the spindle encloses a separation space (9). An upper bearing housing (20) is mounted to the stationary frame and supports bearings (22, 23) comprising an outer bearing ring (24) attached to the upper bearing housing and an inner bearing ring (25) attached to the spindle. The upper bearing housing is mounted to the stationary frame (2) via an elastic member (40) permitting the upper bearing housing and the spindle to move radially, and via an upper tilting member (41) permitting the spindle to tilt during operation of the centrifugal separator.

    Abstract: There is provided an electric motor/generator comprising a stator and a rotor. The stator has an outer perimeter. The rotor at least coaxially encloses the outer perimeter of the stator. The rotor is rotatable relative to the stator around a rotation axis. The rotor and the stator are separated by a flux bearing gap over which in working magnetic flux occurs. The rotor and the stator are separated by a protective gap. The protective gap is configured to close, during a deformation of the rotor, before the flux bearing gap closes, thereby avoiding closure of the flux bearing gap. The motor/generator is characterized in that the stator comprises a roller bearing and an axle. The roller bearing is coupled to the axle and rotatable around the axle. The axle is arranged off-center from the rotation axis. A distance between the roller bearing and the rotor defines the protective gap.

    Abstract: Abstract of the disclosure: A controllable bearing system for supporting a rotatable element comprises a bearing (102), spring equipment (105), and at least one electromagnet (106). The bearing is mechanically supported to be movable with respect to the rotatable element in the axial direction of the bearing. The spring equipment generates spring force for axially pressing the bearing so as to make the bearing system to support the rotatable element. The electromagnet is suitable for generating magnetic force directed against the spring force and keeping the bearing system detached from the rotatable element. Electrical current of the electromagnet determines whether the bearing system supports the rotatable element or is detached from the rotatable element. Thus, the bearing system is suitable for an auxiliary bearing that needs to be detached from the rotatable element during a normal operation and to support the rotatable element when main bearings, such as magnetic bearings, are non-operating.

    Abstract translation: 本公开的摘要:一种用于支撑可旋转元件的可控轴承系统,包括轴承(102),弹簧设备(105)和至少一个电磁体(106)。 轴承被机械地支撑成可在轴承的轴向方向上相对于可旋转元件移动。 弹簧设备产生用于轴向按压轴承的弹簧力,以使轴承系统支撑可旋转元件。 电磁铁适于产生针对弹簧力的磁力并保持轴承系统与可旋转元件分离。 电磁铁的电流确定轴承系统是支撑可旋转元件还是与可旋转元件分离。 因此,轴承系统适合于在正常操作期间需要从可旋转元件拆卸的辅助轴承,并且当主轴承(例如磁性轴承)不工作时支撑可旋转元件。

    Abstract: A multi-axis manipulator in the form of a robotic arm includes a safety disc (41) and safety collar (42) at one or more of the pivoting joints (14, 17, 19, 21, 23) thereof. The disc and collar define a small running clearance in normal use, but make contact in the event of excessive wear or failure of the rotary bearing at the respective joint. An inspection window (48) permits the running clearance to be checked, and the collar may comprise a caliper brake.

    Abstract: A vacuum pump with a magnetic bearing assembly includes the magnetic bearing assembly with rotor position sensors and backup bearings being placed inside the rotatable shaft of the vacuum pump. The sensor placements are independent of the bearing position, so that the respective radial sensors can be at the same axial positions as the respective radial bearings, which provides sensors co-location and a space saving within a turbopump housing, in particular, in its axial direction, while sensors and mechanical backup bearings are placed in a better protected area with respect to pumped corrosive gases.
