    [0001] [0001] The subject matter disclosed herein relates to systems and methods for monitoring rotation of components in rotary equipment.
    [0002] [0002] Rotary equipment, such as turbomachinery, has one or more rotating components, such as a shaft, a rotor, an impeller, compressor blades, turbine blades, or wheels. The operational parameters of the rotating components may be described by one or parameters, such as rotational speed and torque. Unfortunately, complex machinery such as gas turbine engines may complicate the use of monitoring equipment due to the size, complexity, and precision of rotating components. Therefore, it may be desirable to improve the monitoring of rotating components while reducing the cost, size, load, stress, and overall impact of the monitoring equipment on the rotating components.SUMMARY OF THE INVENTION

    [0012] [0012] One or more specific embodiments of the present invention will be — described below. In an effort to provide a concise description of these embodiments, all features of an actual implementation may not be described in the specification. It should be appreciated that in the development of any such actual implementation, as 3
    [0013] [0013] When introducing elements of various embodiments of the present invention, the articles “a,” “an,” “the,” and “said” are intended to mean that there are — one or more of the elements. The terms “comprising,” “including,” and “having” are intended to be inclusive and mean that there may be additional elements other than the listed elements.
    [0014] [0014] Sensors of a monitoring system provide feedback to a controller (e.g., a processor-based industrial controller) to determine operational parameters (e.g. rotational parameters, environmental parameters) of rotating components. For example, the rotating components may include shafts, rotors, wheels, impellers, or rotary blades (e.g., compressor or turbine) of rotary machines, such as turbines, compressors, pumps, generators, motors, or various turbomachinery. One or more windows detectable by a sensor of the monitoring system are disposed about a rotating component. Each sensor provides feedback to the controller when the respective sensor senses a window (e.g., when the window traverses the sensor). As the rotating component rotates about an axis, the controller determines operational parameters (e.g., rotational parameters) based at least in part on the received feedback over a time period. In some embodiments, the rotational parameters that the controller may determine include, but are not limited to, rotational speed, non- rotation, differential (e.g., thermal) expansion and contraction, changes in rotational direction, changes in speed, torque, angle of twist, changes in torque, torsional vibration, or any combination thereof.
    [0015] [0015] The controller may determine the operational parameters (e.g., rotational parameters, environmental parameters) by observing the frequency at which one or 4
    [0016] [0016] A measurement strip with the one or more windows as described herein may be formed from a flexible sheet by laser cutting, water-jet cutting, stamping, machining, plasma cutting, or another removal process. In some embodiments, the measurement strip and/or the one or more windows of the measurement strip may be — formed from an additive process, such as welding, brazing, application of an adhesive, layered deposition (e.g., 3D printing), or any combination thereof. The measurement strip may be secured to the rotating component (e.g., shaft) at an axial location, such that the one or more windows correspond to respective tangential locations on the rotating component (e.g., shaft). Measurement strips as described herein secure the one or more windows to the rotating component (e.g., shaft) with a reduced effect on the rotordynamic response as compared with machined wheels. The measurement strip may be a unitary component that may be arranged about the rotating component (e.g., shaft) from a radial direction. Radial installation of the unitary measurement strip enables the one or more windows to be arranged about a rotating component (e.g, shaft) of an assembled rotational system with limited access to the shaft.
    [0017] [0017] Turning to the drawings, FIG. 1 is a schematic diagram that illustrates an embodiment of a rotational system 10 (e.g., rotary machinery such as turbomachinery) and a rotational monitoring system 12. In the rotational system 10, a driver 14 rotates a shaft 16 coupled to one or more loads 18. The driver 14 may include, but is not limited to, a gas turbine, a steam turbine, a wind turbine, a hydro turbine, a reciprocating engine (e.g., diesel, gasoline, pneumatic), an electric motor, or any combination thereof. The driver 14 provides a rotational output via the shaft 16 to the one or more loads 18, each of which may include, but is not limited to, a vehicle or a stationary load. In some embodiments, the one or more loads 18 may include a propeller on an aircraft, an electrical generator in a power plant, a compressor, a pump, a fan, a machine, any suitable device capable of being powered by the 5
    [0018] [0018] The monitoring system 12 monitors the rotational system 10 and determines one or more operational parameters of components (e.g., driver 14, shaft 16, load 18) of the rotational system 10. Operational parameters may include rotational parameters, such as rotational speed, non-rotation, axial or radial expansion, axial or radial contraction, changes in rotational direction, changes in speed, torque, angle of twist, changes in torque, torsional vibration, or any combination thereof. Operational parameters may also include environmental parameters, such as differential expansion (e.g., thermal expansion and thermal contraction). One or more sensors 24 arranged along the rotational system 10 sense one or more windows 26 arranged at specific locations (e.g., tangential or circumferential locations relative to a reference angle) of the rotational system 10. For example, the windows 26 may be circumferentially spaced at different angular positions or spacings circumferentially about the axis 20. Each sensor 24 transmits feedback to a controller 28 based at least in part on when the respective sensor 24 senses a window 26 as the windows 26 rotate about the axis 20. In some embodiments, multiple sensors 24 may be arranged at an axial position to monitor one set of windows 26. For example, sensors 24 may be arranged on opposite sides or orthogonal sides of a rotational component (e.g., shaft 16), thereby enabling the monitoring system 12 to reduce or eliminate timing distortions due to radial vibration of the rotational component.
    [0019] [0019] A processor 30 of the controller 28 determines one or more operational parameters from the received feedback. The controller 28 may store received feedback and/or instructions or code for processing the received feedback in a non- transitory machine-readable medium 32, such as memory. The non-transitory machine-readable medium 32 (e.g., memory) does not include transitory signals, and may be volatile memory or non-volatile memory. In some embodiments, the non- transitory machine-readable medium 32 may include, but is not limited to, random access memory (RAM), read-only memory (ROM), flash memory, a hard drive, or 6
    [0020] [0020] Each of the one or more windows 26 is arranged on a measurement strip 34 (e.g, an annular measurement strip 34), which is secured about a rotating component (e.g., driver 14, shaft 16, load 18) of the rotational system 10. As discussed in detail below, the one or more windows 26 include, but are not limited to, recesses fully or partially through the measurement strip 34, raised portions of the measurement strip 34, or differently textured portions of the measurement strip 34, or any combination thereof. In some embodiments, the measurement strip 34 may have one or more layers, and a layer within the measurement strip 34 may have voids and/or inserts. The voids and/or inserts may have different characteristics (e.g., electrical conductivity, magnetic reluctance) relative to other layers or portions of the measurement strip 34. The one or more sensors 24 may sense the voids and/or inserts as windows 26. The one or more windows 26 are arranged to be detectable from a radial direction 36 by the one or more sensors 24. For example, each of the one or more sensors 24 may include an eddy current sensor, a capacitance sensor, a magnetic reluctance sensor, a contact sensor, or a displacement sensor, or any combination thereof. During operation, one or more of the windows 26 may become partially obstructed with debris (e.g., lubricant, dust, particulates). Accordingly, a non-optical sensor 24 (e.g., eddy current sensor, capacitance sensor, magnetic reluctance sensor) may sense the one or more partially obstructed windows 26 despite the debris.
    [0021] [0021] The monitoring system 12 may determine one or more operational parameters of a rotational component (e.g., driver 14, shaft 16, load 18) with one or more secured measurement strips 34 utilizing feedback received from the one or more sensors 24. The monitoring system 12 may determine the rotational speed (e.g., rotations per minute (RPM)) or a non-rotation condition of a rotational component (e.g., shaft 16) via observing the frequency at which a first window 38 on a first measurement strip 40 is sensed during an observation period. In some embodiments, the monitoring system 12 may determine the thermal expansion or thermal contraction of the shaft 16 based at least in part on sensing the first window 38 with a first sensor 7
    [0022] [0022] The monitoring system 12 may determine reverse rotation and changes in the rotational speed via observing the frequency and/or sequence at which multiple windows 26 of the first measurement strip 40 are sensed during an observation period. For example, a second window 48 on the first measurement strip 40 may have a — different geometry and/or orientation than the first window 38. The controller 28 may determine the rotational direction based at least in part on the sequence the first sensor 42 senses the first and second windows 38, 48. Additionally, the controller 28 may determine the rotational speed of the shaft 16 multiple times per revolution of the shaft 16 based at least in part on feedback corresponding to the first and second — windows 38, 48. For example, the controller 28 may determine the rotational speed of the shaft 16 utilizing frequency of observing the first window 38, frequency of observing the second window 48, and/or elapsed time between observations of the first window 38 and the second window 48.
    [0023] [0023] In some embodiments, the monitoring system 12 may include multiple measurement strips 34, each measurement strip 34 having one or more windows 26. The monitoring system 12 may determine rotational conditions such as torque and torsional vibration based at least in part on feedback corresponding to windows 26 on different measurement strips. Torque on the shaft 16 during operation of the rotational system 10 may twist the shaft 16 about the axis 20 between the driver 14 and a first load 49. As discussed in detail below, the controller 28 may utilize feedback from the first sensor 42 sensing the first measurement strip 40 and from a second sensor 50 sensing a second measurement strip 52 to determine the torque on the shaft 16 and/or torsional vibration of the shaft 16. In some embodiments, windows 26 at different axial locations are aligned tangentially, thereby enabling the monitoring system 12 to observe the aligned windows substantially simultaneously when the rotating component is not twisted about the axis 20. The controller 28 may 8
    [0024] [0024] FIG. 2 illustrates a perspective view of an embodiment of the rotational system 10 with the rotational monitoring system 12. The driver 14 rotates the shaft 16 and the load 18 about the axis 20 in a first tangential direction 60 and/or a second tangential direction 62. Cylindrical-polar coordinate axes 64 depicts the longitudinal (e.g., axial) axis 66 along the axis 20, a radial axis 68, and an angular (e.g., tangential) component 70 relative to a reference angle 72. The first measurement strip 40 may be secured to the shaft 16 such that the first window 38 is aligned with the reference angle 72. In some embodiments, the monitoring system 12 may relate a first edge 74 of the first window 38 to a zero-orientation (e.g., 0°) of the shaft 16. The third window 54 on the second measurement strip 52 may also be aligned with the reference angle 72 (e.g., tangential location). That is, each window 26 may be aligned with a corresponding tangential location of the rotating component when the rotating component is at rest (e.g., substantially no torque on shaft 16). For example, a second edge 76 of the third window 54 may be aligned with the reference angle 72 when the shaft 16 is not rotating. Upon rotation of the shaft 16, the torque on the shaft 16 > between the driver 14 and the load 18 may twist the shaft 16. The torque on the shaft 16 may displace the second edge 76 by an arc distance 78 relative to the first edge 74 and the reference angle 72. The controller 28 may determine the angle of twist from the arc distance 78, and the controller 28 may determine the torque on the shaft 16 based at least in part on the arc distance 78, a distance 80 between the first window 38 and the third window 54, a material of the shaft 16, and a structure (e.g., solid, hollow, circular, square) of the shaft 16. In some embodiments, the controller 28 may 9
    [0025] [0025] The controller 28 may determine torsional vibration on the shaft 16 by — comparison of the feedback received from the first sensor 42 to the feedback received from the second sensor 50. As may be appreciated, the first sensor 42 may detect the first edge 74 at a first time (T1), and the second sensor 50 may detect the second edge 76 at a second time (T>). Changes in torque on the shaft 16 may result in differences between Ti and T,> while the rotational speed changes. The controller 28 may determine the arc distance 78 and/or the angle of twist between the first measurement strip 40 and the second measurement strip 52 from the differences between Ti and Ts. In some embodiments, the first sensor 42 may detect a third edge 79 of the second window 48 at a third time (T;). Differences between Ti and Ts (e.g., AT) during operation of the rotational system 10 may identify a torsional vibration rotational parameter. The controller 28 may determine a magnitude and/or a source of the torsional vibration by evaluating changes to AT over a time period (e.g., 0.1 seconds,
    [0026] [0026] Embodiments with multiple windows 26 on each measurement strip 34 may enable the monitoring system 12 to determine rotational parameters (e.g., the torque and/or torsional vibration) with more precision and/or more accuracy than embodiments with only a first window 38 and a third window 54. Additionally, multiple windows 26 increase the available feedback to the monitoring system 12, 10
    [0027] [0027] In some embodiments, the first window 38 has a second edge 82 that is oblique relative to the first edge 74 and the axis 20. As may be appreciated, the shaft 16 may expand axially as the temperature of the shaft 16 increases, and contract axially as the temperature of the shaft 16 decreases. When the shaft 16 is at a first temperature (e.g., 20 degrees C), the first sensor 42 senses a first arc 84 length between the first edge 74 and the second edge 82. When the shaft 16 is at a second temperature (e.g., 50 degrees C), the first sensor 42 senses a second arc length 86 — between the first edge 74 and the second edge 82. The first measurement strip 40 is secured to the shaft 16 at a first axial location 88 along the shaft 16, and the second measurement strip 52 is secured to the shaft 16 at a second axial location 90. Based at least in part on the detection of the first window 38, the controller 28 may determine a length of the shaft 16 and/or the distance 80 between the first and second axial locations 88, 90. Additionally, or in the alternative, the controller 28 may determine changes to a length of the shaft 16 and/or the distance 80 due to torque on the shaft
    [0028] [0028] In some embodiments, the sensors 24 sense a distance 92 between the sensor 24 and the measurement strip 34. As may be appreciated, the shaft 16 may expand and contract in the radial direction 68 with temperature or torque variations on the shaft 16. The distance 92 may correspond to a radial clearance 96 between a 11
    [0030] [0030] The measurement strip 34 is a separate component from the rotary component (e.g., shaft 16) that may be removably or fixedly secured to the rotary component (e.g., shaft 16). In some embodiments, the measurement strip 34 is disposed about substantially all (e.g., greater than 270°) of the shaft 16 at the axial location 104. A first end 106 of the measurement strip 34 may interface with a second — end 108 of the measurement strip 34 when the measurement strip 34 is secured about the shaft 16. For example, the first end 106 may mate with the second end 108. In some embodiments, the securing mechanism 100 to secure the measurement strip 34 about the shaft is a bond between the first end 106 and the second end 108. For example, the securing mechanism 100 may include, but is not limited to a weld, a braze, an adhesive, an interference fit via heat treatment, or any combination thereof. In some embodiments, the first and second ends 106, 108 may accommodate a fastener 110 (e.g., screw, bolt, snap, clasp, hook) to secure the measurement strip 34 about the shaft 16.
    [0031] [0031] Additionally, or in the alternative, one or more bands 112 may secure the measurement strip 34 about the shaft 16. Each band 112 may be tightened about the measurement strip 34 and the shaft 16, thereby securing the measurement strip 34 at the axial location 104. Each band 112 may include a fastener 110 (e.g., screw, bolt, clip, button) to close the band 112 about the measurement strip 34. In some embodiments, a nut 114 couples with the fastener 110 to tighten the band 112 about the measurement strip 34. The fasteners 110, the nuts 114, and/or the bands 112 may have tethers 116 to secure the connection with the shaft 16 should the fastener 110, 13
    [0032] [0032] The bands 112 may be arranged to secure the measurement strip 34 such that the windows 26 are detectable from the radial direction 68. As discussed above, — the first window 38 is to be secured about the shaft 16 such that the first edge 74 corresponds to a reference angle 72 (e.g., 0°). In some embodiments, the first window 38 may be different from the other windows 26, such as having a sub-window, to identify the first window 38 among the other windows 26. Each of the other windows 26 may be spaced apart from the first window 38 by a defined arc distance 122 and/or angle 70. In some embodiments, the spacing between the windows 26 may be uniform. For example, the measurement strip 34 illustrated in FIG. 3 has eight sets of windows 26 spaced 45° apart. Presently contemplated embodiments may include, but are not limited to, windows 26 spaced apart by approximately 5°, 10°, 15° 20° 30° 40°, 50%, 60%, 90%, or more, or any combination of such spacings. Accordingly, the — monitoring system 12 may determine some operational parameters (e.g., speed, angular position) at least eight times per revolution of the shaft 16. Additionally, or in the alternative, the spacing between the windows 26 may be non-uniform. For example, the spacing between sequential windows 26 may increase by approximately
    [0033] [0033] Some embodiments of the measurement strip 34 may be formed from sheet metal or another relatively thin material with respect to the radius 103 of the shaft 16. For example, a thickness 126 of the measurement strip 34 may be less than 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10% of the radius 103 of the rotating component. In some embodiments, a thickness 126 of the measurement strip 34 may be less than approximately 19 mm, 12.7 mm, 6.4 mm, 3.2 mm, 1.6 mm, 0.4 mm, or less (e.g, approximately 0.75 in, 0.5 in, 0.25 in, 0.125 in, 1/16 in, 1/64 in, or less). The mass of the measurement strip 34 may be an insignificant contribution to the mass and the inertia of the rotational system 10 or the rotation component (e.g., shaft 16) to which — the measurement strip 34 is secured. For example, the mass of the measurement strip 34 may be less than 0.01, 0.1, 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10% of the mass of the rotational system 10 or the rotating component (e.g., shaft 16) to which the measurement strip 34 is secured. Accordingly, the mass of the measurement strip 34 may have a substantially negligible effect on the rotordynamic response of the rotational system 10.
    [0034] [0034] FIG. 4 illustrates an embodiment of the formation of the measurement strip
    [0035] [0035] Technical effects of the invention include that the measurement strip 34 may be formed from one piece of material (e.g., rolled sheet 130) and may be secured to an axial location 104 of a rotating component from an axial or radial direction with minimal effect on the rotordynamic response of the rotating component due to the size and mass of the measurement strip 34. The unitary construction, size, and flexibility of the measurement strip 34 may enable a technician to install the measurement strip 34 with less time, less effort, and/or at a lower cost than installation of a split machined wheel or machined shaft of a rotational system. The technician may form the windows 26 on the measurement strip 34 to a desired tolerance level utilizing a variety of tools and processes for a lower cost than precision machining the shaft 16 and/or a machined split wheel with the same desired tolerance level. One or more measurement strips 34 as described herein may be utilized to determine one or more operational parameters of the rotational system, including, but not limited to rotational speed, non-rotation, differential expansion, changes in rotational direction, changes in speed, torque, changes in torque, torsional vibration, or any combination thereof.
