Definitions

  • the invention relates to an arrangement for calibrating a bearingless on the one hand with a drive shaft flange and on the other hand with a driven shaft flange nadoverbind- ble, consisting essentially of two axially spaced flanges with intermediate torque transmission and measuring range existing torque sensor, with at least one for calibration instead one of the shaft flanges attachable to the associated sensor flange, at least one-sided calibration lever, at the sensor end remote from the outer end (s) at least one calibration weight in a defined distance to the sensor axis can be attached.
  • Torque sensors of the type mentioned are known, inter alia, from DE 199 36 293 A1 and are used for example on test benches for internal combustion engines, gearboxes, drive trains and the like.
  • they are easy to install with a small footprint and due to their low mass and small dimensions Do not or at least only negligibly influence the measured torque to be measured.
  • such sensors must be calibrated at least from time to time, ie the measurement signals supplied by the sensor and processed in the connected evaluation unit must be related to torques actually acting on the sensor.
  • a preferably two-armed calibration lever is usually attached to one of the sensor flanges, wherein the other sensor flange either remains connected to the blocked input or output shaft flange or, after a complete removal of the sensor, is mounted on a separate, stationary auxiliary device.
  • Object of the present invention is to improve a calibration arrangement of the type mentioned above so that the mentioned irregular loads of the torque sensor are reduced and thus the calibration accuracy and ultimately the actual measurement accuracy of the calibrated torque sensor is increased.
  • the calibration lever is formed cranked, wherein the crank preferably inside, in the vicinity of the attachment to the sensor flange, is located.
  • the fictitious point of application of the calibration weight can be adjustable in a further preferred embodiment of the invention in the axial and / or radial direction, preferably by adjustable attachment of the actual weight support and / or adjustable mounting of the parts of the calibration lever relative to each other.
  • the compensation of the bending moment can be influenced, which in this way is e.g. can be compensated even with different adapter flanges or similar spacers.
  • FIG. 1 shows an internal combustion engine test bench with built-in torque sensor of the type to be calibrated with an arrangement according to the present invention
  • FIG. 2 shows a prior art calibration arrangement
  • FIG. 3 shows a calibration arrangement according to the present invention
  • an internal combustion engine 2 standing on base elements 1 is connected to an electric drive or loading machine 4 on a test stand 3, with the internal combustion engine side drive shaft flange 5 and the electric machine side output shaft flange 6 (or vice versa) directly are connected to a torque sensor 7 arranged therebetween.
  • sensors 7 are shown in more detail in FIGS. 2 to 4 and known for example from the aforementioned DE 199 36 293 Al. They are by means not shown here flange bolts and without additional bearings, connecting shafts or the like easy to install and offer by small dimensions and low mass the advantage that the measurement of the internal combustion engine 2 and electric machine 4 (or vice versa) über ⁇
  • the calibration lever 11 is designed so that the plane of rotation of the fictitious point of application Kalibrierwhenes 16 with the bearing of the outer contact surface 14 of the calibration lever 11 sensor flange 9 spanned, located perpendicular to the sensor axis 12 plane of rotation 17 coincides, whereby the distance 18 (as shown in FIG. 2) is zero. Since the manufacturers of such torque sensors 7 generally refer the irregular loads or their permitted sizes to the outer contact surface 14 or the fictitious plane of rotation spanned therefrom, the irregular bending load to be taken into account is at least theoretically completely eliminated, so that the calibration accuracy can be substantially improved. As in the arrangement of FIG.
  • the cranked according to FIG. 3 and 4 formed calibration lever 11 carries the crank 19th advantageously inside, in the vicinity of the attachment to the sensor flange 9, which gives greater stability.

Abstract

Selon l'invention, pour étalonner un capteur de couple (7) monté de manière fixe d'un côté, un levier d'étalonnage (11) comportant, à l'extérieur, un poids d'étalonnage à une distance définie de l'axe de capteur (12) est fixé sur le bord (9) libre du capteur. Pour réduire ou supprimer le couple de flexion irrégulier agissant sur le capteur de couple (7) par l'intermédiaire du levier d'étalonnage (11), ce dernier est coudé. Le point de contact fictif du poids d'étalonnage est décalé au moins approximativement dans le plan de rotation (17) correspondant à la surface de contact extérieure (14) du bord de capteur (9) présentant le levier d'étalonnage (11).
