  • Patent number: 9044812
    Abstract: A jig and a method for modifying a casing in a turbine system are disclosed. The jig includes a body and a protrusion extending from the body. The protrusion is configured for engaging a hole defined in a spot face on the casing. The jig further includes at least one machining passage defined in the body, the machining passage provided for machining the casing therethrough, and at least one alignment feature configured on the body, the at least one alignment feature provided for aligning the jig with respect to the casing. The method includes engaging a jig with a hole defined in a spot face on the casing, aligning the jig with respect to the casing, and machining at least one installation hole into the casing through the spot face.

  • Publication number: 20150010386
    Abstract: Systems and devices configured to determine misalignment of targets of a rotating shaft by monitoring axial and radial aspects of targets and the shaft. In one embodiment, a target monitoring system includes a first horizontal probe communicatively connected to at least one first horizontal target connected to the shaft, and a first axial probe located adjacent to the first horizontal probe and communicatively connected to the first horizontal target. The system also includes a second horizontal probe communicatively connected to at least one second horizontal target connected to the shaft, and a second axial probe located adjacent to the second horizontal probe and communicatively connected to the second horizontal target. The system may further include an end probe disposed proximate a first end of the shaft for monitoring axial movement of the shaft, and a computing device communicatively connected to the end probe and each horizontal and axial probe.

  • Patent number: 8539810
    Abstract: According to one aspect of the invention, a method for calibrating a torque measurement for a rotatable object is disclosed, wherein the method includes coupling the rotatable object to a structure, the structure including a member extending along a length of a surface of the rotatable object, coupling the rotatable object to an adapter and applying a known torque to the rotatable object via the adapter. The method also includes measuring a first rotational displacement via a first sensor coupled to the member at a first axial location of the rotatable object, measuring a second rotational displacement via a second sensor coupled to the member at a second axial location of the rotatable object and determining first and second angular displacements of the rotatable object based on the first and second rotational displacements.
