    摘要： The present disclosure concerns a fan disc assembly, and in particular a fan disc assembly for a gas turbine engine. Example embodiments disclosed include a fan disc assembly for a gas turbine engine, comprising: a fan disc with a central bore comprising a bore forward section, a bore aft section and a bore spline between the bore forward and aft sections; a shaft mounted within the central bore of the fan disc, the shaft comprising a shaft forward section connected to the bore forward section, a shaft aft section connected to the bore aft section and a shaft spline between the forward and aft sections and mating with the bore spline, wherein an outer radial surface of the bore forward section is secured to an inner radial surface of the shaft forward section with a second interference fit.

    摘要： A workpiece clamp device with single side is disclosed. When a bolt is screwed in relative to a base plane, an elastic member is compressed by a first and a second stop portions and a second clamp surface of a driving block is limited by a second wall surface. A first inclined surface is pushed leftward by a second inclined surface so that a tool is clamped by the first clamp surface and a first wall surface. When the bolt is screwed out relative to the base plane, the elastic member is reset due to the compression of the first and the second stop portions. Since the second clamp surface is limited by a second wall surface, the first inclined surface is pushed rightward by the second inclined surface to move the driving block upward so that the force for clamping the tool is released and the tool is disassembled.

    摘要： 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.
