  • Page 10: Torque Flange Versions

    T10FS Torque flange versions In the case of option 2 "electrical configuration", the T10FS torque flange exists in versions KF1, SF1 and SU2. The difference between these versions lies in the electrical inputs and outputs on the stator, the rotors are the same for all the versions of a measuring range.

  • Page 11: Application

    T10FS Application T10FS torque flanges record static and dynamic torque on fixed or rotating shafts and also return RS 422 signals with direction of rotation information to determine the speed. With an optical measuring system, a reference pulse can also be output with the speed pulses. Test beds can be extremely compact because of the short construction of the measurement flanges.

  • Page 12: Structure And Mode Of Operation

    T10FS Structure and mode of operation Torque flanges consist of two separate parts: the rotor and the stator. The rotor comprises the measuring body and the signal transmission elements. Strain gages (S.G.) are mounted on the measuring body. The rotor electronics for transmitting the bridge excitation voltage and the measurement signal are located centrally in the flange.

    (medium strength) to exclude prestressing loss due to screw slackening. An appropriate shaft flange enables the T10FS torque flanges to be mounted directly. It is also possible to mount a joint shaft or relevant compensating element directly on the rotor (using an intermediate flange when required).

  • Page 14: Conditions On Site

    The measurement flange can be mounted in any position. With clockwise torque, the output frequency is 10 kHz to 15 kHz. With HBM amplifiers or with the "voltage output" option, a positive output signal (0 V to +10 V) is present.

  • Page 15: Installation Possibilities

    T10FS 4.3 Installation possibilities In principle, there are two possibilities for torque flange mounting: with the antenna ring complete or dismantled. We recommend proceeding as described in subsection 4.3.1 . If installation in accordance with 4.3.1 is not possible, (e.g. in the case of subsequent stator replacement or mounting with a speed measuring system), you will have to dismantle the antenna ring.

    T10FS 4.4 Mounting the rotor Additional installation notes for the speed measuring system can be found in Section 4.7, Page 23. NOTE In general, the rotor identification plate is no longer visible after mounting. This is why we include with the rotor additional stickers with the important ratings, which you can attach to the stator or any other relevant test bench components.
  • Page 19 T10FS 2. Use eight DIN EN ISO 4762 hexagon socket screws of property class 10.9 (measuring range w3 kNVm: 12.9), of the appropriate length (depending on the connection geometry) to screw fasten the rotor. We recommend fillister head screws DIN EN ISO 4762 or similar, blackened, smooth headed, permitted size and shape variance in accordance with DIN ISO 4759, Part 1, product class A.

    T10FS 4.7 Installing the slotted disc (speed measuring system) To prevent the slotted disc of the optical speed measuring system being damaged in transit, it is not mounted on the rotor in the case of measurement flanges with option 2, code L (nominal (rated) speed 8000 min 15000 min ).

  • Page 24: Fitting The Mounting Elements (Speed Measuring System)

    T10FS 4.8 Fitting the mounting elements (speed measuring system) Three mounting elements with screws are included with the torque flange to prevent the speed sensor being damaged during installation. The mounting elements hold the rotor centrally in the antenna ring, making installation easier and safer.

  • Page 25: Fixing The Mounting Elements

    T10FS 4.8.1 Fixing the mounting elements 1. Place the rotor with the identification plate upward on a flat base. For the optical speed measuring system only: Hold the stator at a slight slant and push it over the rotor until the slotted disc is located in the optical sensor (Step A, Fig.
  • Page 26 T10FS NOTE It is essential to keep the mounting elements and fastening screws in case any modifications are needed! 6. Tighten the stator retaining screws. The stator must rest at the markers or stops. The rotor must turn freely. 7. Check whether the axial and radial tolerances have been maintained.

  • Page 27: Aligning The Stator (Speed Measuring System)

    T10FS 4.9 Aligning the stator (speed measuring system) The stator can be mounted in any position (for example, "upside down" installation is possible). For measuring mode to operate perfectly, the speed sensor (pole ring/slotted disc) of the speed measuring system must be positioned at a defined point on the sensor.
  • Page 28 T10FS Axial alignment There are markers on the sensor head for axial alignment (orientation lines). When installed, the axial inner surface of the pole ring should be exactly over the axial orientation line. Divergence of up to "1.5 mm is permissible in measuring mode (total of static and dynamic shift), in this case however, the pulse tolerance will be greater.
  • Page 29 T10FS Radial alignment The rotor axis and the optical axis of the speed sensor must be along a line at right angles to the stator platform. For radial alignment, the radial distance has to be maintained (see Fig. 4.10). A vertical orientation line on the sensor head facilitates tangential alignment (see Fig.
  • Page 30 T10FS Check radial nominal distance a with a distance gage and compensate for any possible misalignment of the stator by putting adjusting washers underneath or by adjusting the base of the stator. You can also use the central fastening screw on the sensor head for fine adjustments (setting range "1.5 mm).

  • Page 31: Optical Speed Measuring System

    T10FS 4.9.2 Optical speed measuring system Axial alignment There are markers in the optical sensor for axial alignment (orientation lines). When installed, the slotted disc should be exactly above these orientation lines. Divergence of up to "2 mm is permissible in measuring mode (total of static and dynamic shift).
  • Page 32 T10FS Radial alignment The rotor axis and the optical axis of the speed sensor must be along a line at right angles to the stator platform. A vertical marker line on the head of the sensor serves as an orientation guide.

  • Page 33: Electrical Connection

    T10FS Electrical connection 5.1 General instructions We recommend to use shielded, low−capacitance cable from HBM for the electrical connection between torque transducer and measuring amplifier.

  • Page 51: Vibration Suppression (Hysteresis)

    T10FS 7.6 Vibration suppression (hysteresis) Low rotation speeds and higher relative vibrations between the rotor and the stator can cause disturbance signals that reverse the direction of rotation. Electronic suppression (hysteresis) to eliminate these disturbances is connected at the factory. Disturbances caused by the radial stator vibration amplitude and by the torsional vibration of the rotor are suppressed.

  • Page 52: Form Of The Rotation Speed Output Signal

    T10FS 7.7 Form of the rotation speed output signal In the factory settings, two 90_ phase offset speed signals (5 V symmetrical, complementary RS422 signals) are available. You can double the pulse count set in each case by moving switch S6 to the "On" position. Pin 3 then outputs the direction of rotation as a static direction of rotation signal (pin 3 = +5 V, pin 7 = 0 V opposite pin 8), if the shaft turns in the direction of the arrow.
