摘要： A turbine rotor disassembly, handling and reassembly apparatus employs a feedback-controlled electric heating oven to rapidly heat a turbine wheel while the rotor shaft is in the horizontal position. An adapter interfaces the wheel to a handling spool whose outboard end is adjusted to slide on the rotor shaft and to provide a fulcrum for supporting the wheel. A handling trolley includes a soft hydraulic system for supporting the weight of the wheel to avoid damaging the precision machined surfaces of the shrink-fit area while the wheel is being withdrawn. The handling apparatus also provides means for upending, or rotating, the removed wheel through 90 degrees to place its axis vertical for facilitating handling. A sensor system senses a radial motion of the wheel to detect clearance and to establish an appropriate fluid pressure to just balance the weight of the wheel and attached parts. The handling system includes means for rotating the wheel slightly during reassembly to align keyways or the like. A technique is included for equalizing shaft heating during reassembly of a turbine rotor by cyclically elevating and lowering the wheel, by orbiting the wheel about the shaft or by holding the wheel in the center of its clearance about the shaft until a shrink fit is established.

摘要： A method and apparatus are disclosed for measuring and displaying parallelism, or the lack thereof, of first and second flat surfaces using a video monitor and three displacement transducers. The first surface is in a fixed position while the second surface may be fixed or may be adjustable so as to attain parallelism between the surfaces. A first point is selected on the first surface and a second point is selected on the other surface such that the line between the two points is perpendicular to the first surface. The three displacement transducers are zero calibrated between the two points. Subsequently, the transducers are mounted between the two surfaces in a triangular pattern and their output signals are summed and supplied to the video monitor which has a fixed display indicating theoretical parallelism. The output of the transducers is combined so as to display the actual angular relationship between the two surfaces. Movement of the second surface allows alignment of the two displays, which indicates parallelism of the two surfaces. The disclosure illustrates the use of the apparatus for aligning turbine wheels. Additionally, a further transducer may be used to check the flatness of the second surface relative to the first surface after parallelism has been attained.
摘要翻译：公开了一种用于使用视频监视器和三个位移传感器来测量和显示第一和第二平面的平行度或不存在的方法和装置。第一表面处于固定位置，而第二表面可以是固定的或可以是可调节的，以便实现表面之间的平行度。在第一表面上选择第一点，并且在另一表面上选择第二点，使得两点之间的线垂直于第一表面。三个位移传感器在两点之间进行零校准。随后，换能器以三角形图案安装在两个表面之间，并将其输出信号相加并提供给具有指示理论平行度的固定显示器的视频监视器。换能器的输出被组合以显示两个表面之间的实际角度关系。第二表面的移动允许两个显示器的对准，其指示两个表面的平行。本公开示出了用于对准涡轮机叶轮的装置的使用。此外，可以使用另外的换能器来在平行度达到之后检查第二表面相对于第一表面的平坦度。

摘要： An opening clearance measuring tool that functions as a combination taper gauge and parallel gauge includes a wedge-shaped "taper block", a sliding linear scale predisposed to parallel movement along an upper edge of the taper block, and a digital read-out linear scale measuring and display unit that accurately measures a translational displacement of the sliding scale with respect to the taper block and displays the displacement in millimeters. The angle between the upper and lower edge surfaces of the taper block forms the wedge of the tool and defines the particular slope or "taper" for the gauge. The slope is predetermined to incorporate a linear conversion factor between metric and English units so that the display may be used to indicate clearance measurements expressed in mils. The scale measuring and display unit is fixedly secured to the taper block and, as the linear scale slider is moved past (through) the scale display unit, the translational displacement of the slider is measured and displayed. This information may also be provided via electrical connection/communication to an external "data logger" device for further manipulation and storage. The scale slider also includes a set of parallel tapered steps of precise predetermined increments at one end to enable using the tool as a parallel gauge capable of accommodating plural ranges of clearance measurements.
摘要翻译：用作组合锥度计和平行计量器的开口间隙测量工具包括楔形“锥形块”，倾斜于沿着锥形块的上边缘并行移动的滑动线性刻度，以及数字读出线性刻度测量和显示单元，其精确地测量滑动刻度尺相对于锥形块的平移位移并以毫米表示位移。锥形块的上边缘表面和下边缘表面之间的角度形成工具的楔形，并且对于量规定义了特定的斜率或“锥度”。该斜率被预定为在公制和英制单位之间包含线性转换因子，使得显示可以用于指示以密尔表示的间隙测量。刻度测量和显示单元牢固地固定在锥形块上，并且当线性刻度滑块移动通过刻度显示单元时，测量并显示滑块的平移位移。该信息还可以通过电连接/通信提供给外部“数据记录器”装置，以进一步操纵和存储。刻度滑块还包括一组在一端具有精确的预定增量的平行锥形台阶，以使得能够使用该工具作为能够容纳多个间隙测量的平行量规。

摘要： A double lift jack employs a first hydraulic jack having a long, high-speed lift to elevate a platant into an operating position and a second hydraulic jack mounted on the platant having a short, low-speed lift. The two jacks and the platant are mounted in a sturdy, open-topped housing. The long-lift jack is employed to rapidly elevate the platant and the short-lift jack into their operating positions. The platant is thereupon affixed to the housing in the extended position using studs which are passed through a lip on the housing as the platant is elevated. A load base is raised and lowered by operation of the short-lift jack. The load base is stabilized by hardened guide rods which pass through guide holes in the platant. The thus-locked platant provides a stable base and precise guidance for positioning of a load mounted on the load base. When the studs are released, and the long-lift jack is retracted, the load base is rapidly cleared from interference with a load. A hydraulic control system for the two jacks requires that the long-lift jack receive pressurized hydraulic fluid before permitting actuation of the short-lift jack in order to ensure that the platant is urged into its secured position in contact with the lip of the housing whenever the load base is raised or lowered.

摘要： The tool includes a base having an adjustment wedge, a counter wedge slidable on the inclined surface of the adjustment wedge, a plurality of roller bars in a recess on the upper surface of the counter wedge and a cover member supported by the roller bars. A power screw is used to horizontally displace the adjustment wedge to elevate the counter wedge, cover member and, hence, the load. The plurality of roller bars are confined within a recess to constrain relative movement of the cover member and the counter wedge. To release the cover member for movement, roller bars of reduced diameter at the opposite ends of the wedge are removed to permit the cover member to move relative to the counter wedge. Horizontal adjustment screws cooperate between the cover member and the base to precisely control the movement.
