  • Patent number: 10337338
    Abstract: A wheel disk assembly having a wheel disk, a plurality of blade devices fastened along an outer circumference of the wheel disk, a plurality of sealing plates accommodated between the wheel disk and the blade devices such that the sealing plates are moveable in the circumferential direction, and securing devices designed such that the securing devices secure the sealing plates against movement in the circumferential direction. Pins are provided as securing devices, which pins are detachably retained in bores arranged on the wheel disk and reach into recesses that are formed on surfaces of the sealing plates facing the wheel disk, wherein at least one of the pins, preferably all of the pins, are designed such that, in order to disengage a pin from the associated recess, the pin in question can be plunged further into the bore in a resilient manner.

  • Patent number: 10253650
    Abstract: The invention relates to a device for installing and removing a component on a gas turbine, having a rail system on which in particular a rotor can be displaced along a predetermined displacement axis, and having a terminal positioning part which is fixedly connected to the rail system. The positioning part has at least one guide portion which is designed to co-operate mechanically with a respective counterpart guide portion on the housing of the gas turbine, in order to achieve a suitable orientation of the device with respect to the housing of the gas turbine. The positioning part also has at least one connecting section which is designed in each case to form a fixed but releasable connection to a respective counterpart connecting section on the housing of the gas turbine construct.
