  • Patent number: 12049848
    Abstract: The invention relates to a planetary gearbox in a gas turbine engine wherein a plurality of planetary gears are each mounted on a planetary gear bearing journal by a slide bearing, characterized in that a bushing is arranged in an inner bore of at least one planetary gear, which bushing spatially separates the sliding surface of the slide bearing from the inner bore of the planetary gear and the bushing is designed as a replacement part, in particular as a sacrificial part. The invention also relates to a gas turbine engine.

  • Patent number: 12007010
    Abstract: A gear wheel of a transmission, in particular of a transmission of a gas turbine engine is described, which is designed with a groove which extends in the circumferential direction on the outer periphery of a base body of the gear wheel and in which fibers running at least in the circumferential direction are arranged. The fibers surround the base body in the circumferential direction, wherein the fibers at least partially support the operating loads on the gear wheel only on a breakage of the base body.

  • Publication number: 20180160823
    Abstract: The invention relates to a shelfing rack for storing articles like balancing weights, preferably in boxes. The shelfing system or rack is designed to enable an easy extraction of the balancing weights out of their boxes. It includes a plurality of trays, each holding multiple boxes. A slider together with an indicator contact the boxes. In case that a box is the last one in the tray, a requirement display indicates that the tray is nearly empty.

  • Patent number: 8830572
    Abstract: A microscope stand (11) is disclosed, including at least one pivot support (12), a mount (22) attached to a first end (15) of the pivot support (12), and a C-slide displacement assembly (112). The pivot support (12) is held to a stand interface (14) by a parallel guide mechanism (116), which allows the pivot support (12) to perform a circular motion in a vertical plane. The parallel guide mechanism (116) is formed by a cross-lever linkage which is rotatable about a cross-lever axis (115) extending centrally between and parallel to the support axis (113) of the pivot support (12) and the pivot axis (114) of the C-slide displacement assembly (112) and which is connected to both the stand interface (14) and the pivot support (12) in such a way that it transmits its own pivotal state simultaneously and equally to the stand interface (14) and to the pivot support (12).

  • Patent number: 8520302
    Abstract: The present invention relates to a microscope stand (11), in particular a stand for a surgical microscope, including a pivot support (12) and a mount (22) for mounting the microscope (16) to the microscope stand (11). The mount (22) is supported about a first axis of rotation (23) so that it is rotatable relative to pivot support (12) and capable of being braked, the mount being connected via braking force transmission means (30) to a brake (26), which defines a second axis of rotation (27) extending parallel to first axis of rotation (23). The braking force transmission means (30) include two transfer levers (31; 36), whose two ends (32, 33; 37, 38) are connected without play to the mount (22) and the brake (26), respectively, by respective pivot points (41, 46, 51, 56), which are radially spaced apart from their respective axes of rotation (23, 27).

  • Publication number: 20110216402
    Abstract: The present invention relates to a microscope stand (11), in particular a stand for a surgical microscope, including at least one pivot support (12), a mount (22) attached to a first end (15) of the pivot support (12) and adapted to mount the microscope (16) to the microscope stand (11), and further including a C-slide displacement assembly (112) provided on the second end (13) of the pivot support (12) for balancing the microscope (16) about a pivot axis (114) associated with a stand interface (14). The pivot support (12) is pivotable about a support axis/axle (113) held by the C-slide displacement assembly (112). The C-slide displacement assembly (112) is pivotable about a pivot axis (114) relative to the stand interface (14). All pivoting movements can be suppressed by braking force. The pivot support (12) is held to the stand interface (14) by a parallel guide mechanism (116), which allows the pivot support (12) to perform a circular motion in a vertical plane.
