    摘要: 051545044A method and apparatus for compressing, storing and transmitting measurement data correlative to machine status is disclosed in which the measurement data is continuously sensed, sampled and processed to extract significant spectral elements including magnitude and phase information from each successive period of the originally measured data and to store those spectral elements in a memory means from an initial period of significant spectral elements and each successive period of significant spectral elements which have changed since the previous period for developing a compressed data history correlative to a continuous history of the status of the machine being monitored and from which continuous signals can be regenerated and analyzed for any earlier historical time.

    摘要: Telemetry apparatus for a rotating machine shaft includes a fixed collar of lightweight composite material wrapped on the shaft and having embedded in it telemetry apparatus. Measured data such as torque from a strain gauge sensor is transmitted to a stationary sensor by pulses of infrared signals. An array of photovoltaic cells receives energy from a stationary source to power the rotating telemetry apparatus. All rotating electronics is embedded in the composite material which may be, for example, E-type fiberglass. Such composite material provides a resistance to centrifugal forces due to rotation of the shaft but has sufficient transparency to allow both the transmission of data and power to and from the rotating telemetry.

The encapsulation (20) ensconces a sensing element (40) proximate the front end (22) and a portion of a cable (60) which extends from the back end (24). The sensing element or coil (40) is electrically and mechanically connected to the cable (60) by a pair of suitably sized front and rear ferrules (80), (90) secured to a center and coaxial conductor (66), (70) of the associated cable (60) thereby forming a coil and cable assembly (110). At least the rear ferrule (90) includes a shoulder (100) for firmly anchoring the coil and cable assembly (110) within the encapsulation (20). In addition an injection molding process provides the durable encapsulation (20) which bonds with a dielectric (68) of the cable (60) and symmetrically locks the coil and cable assembly (110) therein.

    摘要: An encapsulated transducer (10) includes an injection molded encapsulation (20) having a front end (22) and a back end (24). The encapsulation (20) is a monolith of cured moldable material ensconcing a sensing element (90) proximate the front end (22) and a portion of an information transmitting medium (120) emanating from the back end (24). A component alignment preform (40) operatively couples the sensing element (90) with the information transmitting medium or cable (120). The component alignment preform (40) includes a front ferrule (70) and a rear ferrule (80) bonded thereto and linearly spaced apart along a long axis "A". The component alignment preform (40) further includes an annular recess (44) in which the sensing element or coil (90) is placed so that it is linearly spaced and aligned along the common long axis "A" in which the front and rear ferrules (70), (80) are aligned. A first lead (98) of the coil is electrically connected to the front ferrule (70) and a second lead (100) of the coil (90) is electrically connected to the rear ferrule (80). A back end (48) of the component alignment preform (40) receives a stripped end (122) of the cable (120) such that a center conductor (126) mates with the front ferrule (70) and a coaxial conductor (130) mates with the rear ferrule (80). The respective conductors (126), (130) are electrically and mechanically connected to the pair of front and rear ferrules (70), (80). A protective sleeve (150) is then fitted over the coil (90) thereby forming a sleeved coil and cable assembly (170). This sleeved coil and cable assembly (170) is encapsulated by an injection molding process which provides the durable encapsulation (20) which bonds with itself and with the sleeved coil and cable assembly (170). The sleeved coil and cable assembly (170) is symmetrically disposed within the encapsulation (20) and the encapsulation (20) includes an integrally formed protective wall having an uniform thickness "T" along a forwardmost portion of the sensing element (90).

    摘要: A method for removing electrical runout in a machine shaft is disclosed. Electrical runout relates to electrical irregularities which can result from non-uniform electrical properties of the materials of the observed surface. A non-contacting eddy current proximity transducer is to be utilized and in which such a non-contacting eddy current proximity transducer is positioned to sense the portion of the shaft from which electrical runout is to be removed. The output of the transducer is sensed to provide an indication of the electrical runout to ascertain where the electrical runout is high and low as the shaft is rotated. The portions of surface of the shaft where the electrical runout is high is cold worked to change the resistivity and permeability of the observed material and bring electrical properties of the worked area in line with adjacent areas to cancel or to remove the electrical runout. In the apparatus, means is provided which performs a peening operation on the shaft to cold work the same.

    摘要: A two-wire constant current powered transducer (10) for detecting, integrating and transmitting an acceleration signal (50) received from a piezoelectric crystal (12). The crystal is operatively coupled to rotating machinery (M) such that rotating anomalies correlative of wear or potential failure can be detected early enough for preventative maintenance. The transducer (10) includes two stages (30, 40). The first stage (30) is an integrator which integrates the acceleration to velocity. The second stage (40) is a gain stage. The gain stage operates with a PNP transistor emitter follower to control the output DC bias level and route the integrated acceleration signal back to the control system.
