摘要： A centrifugal compressor and centripetal turbine are interconnected by a central bolt engaging threaded portions in each of the components. The threaded portions have a different pitch so that the rotation of the bolt in a given direction relative to the compressor and turbine pulls them into tight axial engagement with one another. The differential bolt has a necked-down central portion which forms an annular flow path for seal pressurization fluid from one side of the compressor to the other. A locking element that is splined to the compressor is used to keep the differential bolt from loosening once the compressor and turbine have been tightened to the proper degree.

摘要： THE DISCLOSURE ILLUSTRATES A CENTRIFUGAL COMPRESSOR COMPRISING AN INDUCE HUB TELESCOPED OVER AN ADJACENT SHOULDER OF AN IMPELLER HUB. THE INDUCER HUB HAS AN INNER ANNULAR SURFACE WHICH RECEIVES AN ANNULAR RELATIVELY THIN SPLIT RING ELEMENT. WHEN THE COMPRESSOR ROTATES AT HIGH R.P.M''S THE SPLIT RING FRICTIONALLY ENGAGES THE INNER ANNULAR SURFACE OF THE INDUCER HUB TO DAMP VIBRATIONS.

摘要： The disclosure illustrates a high speed clutch assembly incorporated in a differential gas turbine engine to prevent the turbine shaft from rotating at a speed greater than the compressor shaft speed. The clutch assembly comprises a pair of opposed clutch elements on the turbine shaft and compressor shaft, displaceable into engagement with one another. The clutch elements have magnets oriented so that as the rotational speed of the shafts become equal they are magnetically attracted into engagement. A magnetic spring biases the clutch elements away from one another so that they engage when the shaft speeds are substantially equal. In one form the magnetic spring comprises a pair of coaxial sleeve-type magnets positioned on the turbine shaft and compressor shaft to bias the clutch elements apart. In another form it comprises a bar magnet in the turbine shaft and a pair of bar magnets oriented with their longitudinal axis parallel to the axis of the shafts.

摘要翻译： 本公开示出了并入在差动燃气涡轮发动机中的高速离合器组件，以防止涡轮轴以大于压缩机轴转速的速度旋转。 离合器组件包括在涡轮机轴和压缩机轴上的一对相对的离合器元件，其可彼此接合。 离合器元件具有定向的磁体，使得当轴的转速变得相等时，它们被磁性地吸引到接合中。 磁性弹簧将离合器元件彼此偏离，使得当轴速度基本相等时它们接合。 在一种形式中，磁性弹簧包括位于涡轮机轴和压缩机轴上的一对同轴套筒式磁体，以将离合器元件分开。 在另一种形式中，它包括在涡轮机轴中的棒状磁体和一对杆状磁体，它们的纵向轴线平行于轴的轴线。
