    Abstract: A method and apparatus for measuring stem nut wear in a valve having a threaded valve stem that is positioned to engage the threads of a stem nut. In a preferred embodiment, a tool is mounted on the stem nut, wherein the tool rotates when the stem nut rotates. The tool indicates a measurement of stem nut rotation. An indicator indicates stem movement. The stem nut is rotated and the amount of percent wear is observed. Rotation continues until the stem begins to move. The tool provides a reading when the stem begins to move that indicates an amount of stem nut wear.

  • Publication number: 20140190394
    Abstract: Devices to measure bearing wear are known for bearings such as rod-ends, wherein the rod-end must either be removed completely from its installed position or relocated relative to the device each time wear in a different axis is to be measured. Such devices also tend to be relatively large and cumbersome. The present invention provides a device 10 which is a fully portable light-weight apparatus that precisely measures bearings in two axes. When employed for the purpose of assessing bearing wear, the invention is capable of obtaining the measurement in confined spaces, without the need to remove the bearing from its fully installed position or reorient the bearing housing to facilitate both measurements. By using the disclosed apparatus, a user may ascertain the serviceability of a bearing by detecting the level of wear in the bearing allowing timely replacement and/or repair.

  • Patent number: 8752678
    Abstract: A disc brake is arrangeable in a space that accommodates a brake caliper having an application device. The brake caliper is held slidably with guiding elements on a brake carrier, which is fastened with screws to an axle connection at the vehicle. The caliper straddles a brake disc, against which brake pads can be pressed on either side while braking. At least the brake pad on the application side is mounted movably in the direction of the brake disc in a pad shaft of the brake carrier. A device for the visual identification of the wear of a brake pad and/or brake disc is constructed so that for identifying wear, a pointer element, extending in the opposite direction to the brake disc, is connected at least at one screw.

  • Publication number: 20140102791
    Abstract: Described herein is a wear indicator (100) for use in a drill bit or a core head. The wear indicator (100) comprises an elongate element that forms part of the drill bit. The elongate element has a plurality of numbers (110, 120, 130, 140, 150, 160, 170, 180) formed along its length, each number (110, 120, 130, 140, 150, 160, 170, 180) being formed as a void and corresponds to a level of wear in accordance with the IADC dull grading system. As the drill becomes worn, the wear indicator (100) wears at the same rate to reveal one of the numbers (110, 120, 130, 140, 150, 160, 170, 180). The numbers range from “1” to “8” where the number “1” illustrates the least wear and the number “8” indicates the most wear. When unworn, none of the numbers are visible.

  • Patent number: 8622016
    Abstract: A wear indication system for use in turbine engines to measure gap closure that indicates the amount of wear found on a compressor diaphragm outer hook to prevent contact between a compressor vane attached to the compressor diaphragm outer hook and an upstream compressor blade. The wear indication system enables the wear to be serviced before failure occurs. The wear indication system may be formed from a base mounting plate having one or more wearable material layers attached thereto. In one embodiment, the wear indication system may have multiple wearable material layers. The outermost wearable layer may have a cross-sectional area less than a wearable layer to which it is attached to enable visual determination of the amount of wear that has occurred. The wearable layers may be formed from a honeycomb shaped material enabling wear to occur without threatening downstream components with damage.

  • Patent number: 8474474
    Abstract: A method of diagnosing pressure boundary integrity of a control includes choosing a control valve having a valve body, determining a velocity profile within the control valve, choosing an area of the velocity profile, choosing a surface on an exterior of the valve body at or adjacent to the area, forming a pad on the exterior surface overlying the point, applying a testing device to the pad, and measuring a reference thickness of a wall of the valve body through the pad using the testing device. The method further includes applying the testing device to the pad at a time subsequent to measurement of the reference thickness, measuring a first thickness, and comparing the first thickness to the reference thickness. The comparison of the first thickness to the reference thickness can be used to calculate the amount of valve body wall lost during using and the remaining life of the control valve.
