摘要： Apparatus for measuring thrust loading on a rotating shaft. A plurality oftrain gages, electrically connected in parallel and series to form one arm of a Wheatstone bridge circuit, are mounted at equal intervals on a thin strap or band formed to surround the shaft with a predetermined hoop load. Lubricating material disposed between the shaft and the band prevents transfer of friction forces from the shaft to the band. As the thrust loading increases, shaft dilation (girth increase) causes the band to stretch and increase its stress. This hoop stress is measured by the strain gages mounted on the band, and is transmitted as the output signal produced by the bridge via radio telemetry or slip rings to a remote indicator. A second arm of the Wheatstone bridge circuit, to provide compensation for temperature effects, can be provided by an additional strain gage mounted on a block of material identical to that of the shaft which block is in turn mounted on the above thin strap or band.
摘要翻译：用于测量旋转轴上的推力载荷的装置。并联电连接并形成惠斯登电桥电路的一个臂的多个应变片以相等的间隔安装在以规定的环箍负载围绕轴的薄带或带上。设置在轴和带之间的润滑材料防止摩擦力从轴传递到带。随着推力载荷的增加，轴的膨胀（环长度增加）会使带伸展并增加其应力。该环向应力由安装在带上的应变片测量，并作为由桥接器通过无线电遥测或滑环产生的输出信号传输到远程指示器。惠斯登电桥电路的第二臂可以通过安装在与轴相同的材料块上的附加应变计来提供温度效应的补偿，该块的材料依次安装在上述薄带或带上。

摘要： An apparatus is disclosed for measuring axial thrust of a rotating, bearing supported machine shaft. The support bearings are operatively coupled through a shiftable crosspiece to a spring leaf upon which is mounted a variable resistance type strain gauge connected to an extensometric bridge circuit which provides an output indication of the axial thrust.

摘要： THE DISCLOSURE ILLUSTRATES A TORQUE-INDICATING DEVICE OF THE TYPE THAT USES AXIAL REACTION FORCE ON ONE OF A PAIR OF INTERMESHING HELICAL GEARS IN AN OUTPUT GEAR BOX OF AN ENGINE TO DETERMINE THE ENGINE''S TORQUE OUTPUT. LUBRICATING FLUID IN A CHAMBER IS SUBJECTED TO THE AXIAL REACTION FORCE AND ITS PRESSURE REFLECTS TORQUE. AN IMPORTANT FEATURE OF THE INVENTION IS THAT THE CHAMBER IS AUTOMATICALLY REPLENISHED FROM THE ENGINE LUBRICATING SYSTEM DURING CERTAIN CONDITIONS OF OPERATION.

摘要： A method for detecting stick-slip in a drillstring includes (a) measuring a parameter that is a function of a torque applied to the drillstring by a top drive system over a selected time period, the measuring being performed by at least one surface sensor that produces measurement data including torque values over a frequency range; (b) filtering out measurement data that has a frequency outside a selected frequency band, the selected frequency band including a resonant frequency of the drillstring; (c) identifying a minimum and a maximum torque value in the filtered measurement data and determining a difference of these two values; (d) determining a surface stick-slip index by dividing the difference of the maximum and minimum torque values by an average torque value over the selected time period; and (e) displaying the surface stick-slip index on a display.
