Definitions

  • the invention relates to a component having a material recess and a measuring element having at least one sensor, which is frictionally fitted into the material recess.
  • the invention is therefore based on the object to provide a component which allows a better differentiation of different load directions.
  • the senor is arranged on or on the measuring element, that the measuring direction of the sensor substantially coincides with the line of action of the pressure angle.
  • the invention is based on the finding that the differentiation of load directions is facilitated if the sensor or its measuring direction is arranged in a certain way, namely such that the measuring direction of the sensor coincides with the line of action of the pressure angle. It is sufficient if the measuring direction of the sensor approximately coincides with the line of action of the pressure angle, especially since the pressure angle is subject to changes during operation as a function of external loads.
  • the component according to the invention makes it possible to position at least one sensor directly in the force path with maximum load.
  • This force path with maximum load corresponds to the line of action of the pressure angle or the operating pressure angle.
  • This operating pressure angle is due to the external load of the component in a certain range around the constructive nominal pressure angle.
  • the invention makes it possible to determine the relationship between to close between axial load and radial load. If the amount of the load is known, radial loads and axial loads can be determined separately and output in absolute sizes by means of the measuring element.

  • measuring element is arranged axially or radially or obliquely to the axial and / or radial direction in the component.
  • various possibilities are created which allow an adaptation of the arrangement of the measuring element or the sensor to different directions of force.
  • an optimal position of the measuring element can be determined in this way.
  • the senor is arranged on or on the measuring element such that the measuring direction of the sensor substantially coincides with the line of action of the nominal pressure angle or the operating pressure angle.
