Definitions

  • the invention relates to the monitoring of gears whose load during operation can be very high and in case of damage, the replacement of the gear or an entire system is not agile ⁇ .
  • a two-dimensional, i. planar trained, sensor array has a plurality of magneto-elastic sensors which span a surface.
  • Figure 2 is a view corresponding to Figure 1, which is rotated by 90 °.
  • a magneto-elastic sensor 1 is based on the effect of the magnetic permeability change with change in length.
  • the magnetic properties of a material are influenced by occurring mechanical forces acting on the material.
  • the corresponding sensors are characterized by high measuring accuracy and directly measure a force.
  • a sensor of this type is positioned without contact at a certain distance from the object to be measured and can be used during operation.
  • torques on force-transmitting waves can be measured by contactlessly measuring the changes in the permeabilities of a shaft by means of a magneto-elastic sensor.
  • a non-destructive moni ⁇ monitoring of gears is possible, which are subject to mechanical stresses by externally applied forces. It is measured during operation on gears. If a use of a component to be carried out against a quality assurance to be made, the operation can also be simulated, where largely similar operational states Herge ⁇ represents be. For example, one gear is engaged with another gear and a check is made. the gear loaded as in operation. By a magneto ⁇ elastic sensor, the load is measured in simulated operation, so that the forces in the gear to be monitored ⁇ are taken and, for example, certain setpoints of mechanical load to be approached.

Abstract

Procédé destiné à surveiller des engrenages en marche, comportant la mise en œuvre d'au moins un capteur magnéto-élastique (1) à mesure sans contact permettant d'enregistrer des modifications de perméabilité provoquées, le cas échéant, par des contraintes mécaniques au sein de l'engrenage, le positionnement de l'au moins un capteur magnéto-élastique (1) sur l'engrenage à surveiller étant réalisé tel qu'il permet un enregistrement de l'engrenage dans le domaine de contraintes pouvant le cas échéant être fortes et qu'il permet de déterminer des forces en mesurant des modifications de perméabilité. Utilisation : acquisition sans contact de données concernant des engrenages.
