Definitions
- Torque measuring device torque measuring flange and torque measuring method
- the invention relates to a torque measuring device, a torque measuring flange and a torque measuring method.
- Such torque measuring devices are used, for example, in test stands, as disclosed inter alia in DE 10 2006 044 829 A1.
- torque measuring flanges or measuring shafts as described, for example, in DE 42 03 551 A1 or DE 10 2007 005 894 A1 but also in DE 20 2006 007 689 U1, in DE 199 17 626 A1, DE 197 19 921 Al and DE 103 06 306 Al and in the Internet articles "Operating Instructions Torque Measuring Fli / F2i" of GIF Weg für Industrie Wunsch mbH from Aisdorf in Germany (2007 / Rev.1.25) and "User's Manual TF Series Torque Flange Sensors" of Magtrol Inc.
- torque-measuring flange and measuring shaft being used interchangeably in the present context.
- a torque is measured, which in the present context primarily torques of rotating assemblies are measured.
- such assemblies can be selectively subjected to a load during a rotation in order to investigate the behavior of the corresponding assembly under load, in particular with regard to the reaction thereof by means of a changed torque. In this way, in particular wear, durability, extreme load behavior, natural vibration, rattle noise u. ⁇ . Be examined.
- DE 20 2006 discloses a torque measuring shaft which, inter alia, has a digital interface and a temperature sensor for temperature-dependent zero point compensation, ie the compensation of a temperature dependence of the measured value output by the torque measuring shaft when no torque is applied.
- the present invention firstly proposes a torque measuring device with a torque measuring flange and an evaluation, which is characterized in that the evaluation has means for storing a variable proportional to a freewheeling torque and means for compensating a measured value with the stored variable.
- the invention is based on the basic knowledge that a Drehmomentmessflansch in the free-running state, ie in a completely independent of any load applied by any DUT or even an externally applied
- the invention according to the proposed torque measuring device thus makes it possible to determine such a freewheeling moment in which, for example, in a completely unloaded state, a measurement is performed, and the respectively determined or measured
- the present invention proposes, secondly, a method for measuring torque, which is characterized in that initially a free-wheeling torque is determined and the determined torque measured value is subsequently compensated with the free-wheeling torque.
- a torque measuring flange is usually characterized by a measuring device for measuring a variable proportional to a torque acting on the Drehmomentmessflansch size
- the measuring device may comprise strain gauges or other voltmeter, with which a distortion of the torque measuring, which is regularly proportional to a torque , can be recorded.
- a measuring device for measuring a size proportional to a torque acting on the Drehmomentmessflansch all devices, including, for example Displacement measurements or the like, can be used, with which such a size can be measured according sufficiently reliable.
- Torque measuring flange with a measuring device for measuring one to one on the
- Torque measuring flange acting torque proportional size which is characterized by a provided on the Drehmomentmessflansch evaluation unit having means for storing a proportional to a freewheeling torque size.
- the corresponding compensation means for compensating a measured value with the stored, proportional to the freewheeling torque size are provided on the Drehmomentmessflansch.
- Such a configuration makes it possible to carry out a corresponding compensation already directly on the torque measuring flange, in particular even if it rotates. In this way, only the measurement signal present after the compensation needs to be transmitted. Otherwise, it may be necessary to transfer the stored in the memory means on the Drehmomentmessflansch, proportional to the freewheeling torque size or stored in the memory means on the Drehmomentmessflansch, proportional to the freewheeling torque magnitudes in a separate step to an evaluation.
- the freewheeling torque is optionally dependent on the speed. This is presumed to be due to aerodynamic drag or flying forces, or possibly to almost imperceptible assembly inaccuracies or imbalances.
- the storage means comprise means for storing a proportional to a speed-dependent freewheeling torque size associated with a speed. In this way, according to several freewheeling torques can be stored speed-dependent, which then make it possible by suitable extra or interpolation or other, known from the prior art measures, a corresponding compensation. In this case it is also possible, instead of various measured values, to store a correspondingly already extrapolated or interpolated functional dependency.
- the known speed measuring devices have the corresponding sensor exclusively on a stator, such as a housing or a linkage, otherwise the speed or a variable proportional to the speed of a rotor to an evaluation, which regularly just not co-rotate, must be transmitted separately ,
- a stator such as a housing or a linkage
- the present invention thus far from this common practice, since the sensor on the Drehmomentmessflansch, which can just rotate accordingly, should be provided, wherein optionally a stationary, so not co-rotating, signal emits a signal to be detected at each revolution of the sensor.
- a signal generator may be a small permanent magnet, the magnetic field of which can be detected by a rotary sensor rotating with the Hall sensor or reed switch.
- any suitable sensor system with which a rotational speed can be determined sufficiently reliably can be used advantageously.
- the correspondingly determined and compensated measurement result can be transmitted by the torque measuring flange.
- the emission can take place here in any known form, which makes it possible to transmit a measured value or another variable from a first to a second assembly.
- the emission preferably takes place without contact, so that an influence on the measuring arrangement itself can be minimized.
- the fixed part of the torque measuring device may then correspondingly have a receiver which receives the transmitted signal.
- a transmission by light has proven to be particularly advantageous, in particular if the quantity proportional to the rotational speed is transmitted in a frequency-modulated manner. A transmission is then extremely low energy, so that sufficient for the torque measuring a very small source of energy.
- Object of the present invention also solved by a torque measuring device with a Drehmomentmessflansch and an evaluation in which the evaluation by a memory for storing a zero point of the torque measuring flange over time.
- a torque measuring device with a Drehmomentmessflansch and an evaluation in which the evaluation by a memory for storing a zero point of the torque measuring flange over time.
- this can be related to voltages that are introduced by the currently driven measurement program in the measuring body. It is also conceivable that this is related to insufficient stability of the analog signal processing modules and the analog transducers. Just the lack of knowledge of the corresponding relationships and the very long periods in which the corresponding drift is effective, have hitherto prevented a dispute hereby. Only a storage of the zero point as a function of time can allow consideration of this phenomenon.
- a zero-point drift can be determined and a determined torque measured value can be compensated with the zero-point drift.
- the torque measuring device has means for displaying the zero-point drift, so that a user has an overview of the corrections made, in particular in order to be able to check the quality of the measurement.
- a user has an overview of the corrections made, in particular in order to be able to check the quality of the measurement.
- the corrections can be made within the device without a user is charged with a corresponding display.
- torque 0 Nm, waver.
- Mene correction to distinguish even from already known calibrations, which just start directly on the statistical fluctuations and only briefly act accordingly calibrating.
- the zero values are stored in the memory at a constant temperature.
- constant temperature denotes a state in which the temperature changes less than a predetermined temperature difference within a predetermined time interval.
- zero values are stored for zero-point drift determination if the measured torque is below a threshold value over a plurality of measurements.
- the zero points can be recorded independently of the influence of a user, so that, depending on the specific implementation, it is possible to automatically record the zero points and - if necessary - to make a corresponding compensation automatically. This can relieve a user and minimize the risk of operating errors. It will be appreciated that other approaches to automation may be used, the approach described above being a relatively simple and reliable approach.

- a torque measuring flange with a load change hysteresis below 0.03% of the rated torque can be provided, which surprisingly also has a very low zero point drift.
- the necessary corrections can be minimized in their absolute value, although a zero-point drift can not be avoided without such corrections.
- a correction of the zero-point drift can be dispensed with if it is structurally correct Measures the size of the drift sufficiently low and can be detected by simple calibration measures before or after each measurement.
- a corresponding memory for storing the zero points of the Drehmomentmessflansches as a function of time can be provided on the one hand in a stationary evaluation of the torque measuring device.
- the memory may also be arranged on or on a corresponding Drehmomentmessflansch, so that the corresponding values and corrections are made before the transmission of a measured value to the stationary system of the corresponding torque measuring device, as this has already been explained for the freewheel correction.
