Definitions

  • the present invention relates to a modular force transducer system for measuring forces acting substantially transversely on an axis, in particular a measuring axis, comprising: a first module comprising an axle body extending along a longitudinal axis, the axle body having a force introduction portion, has at least one bearing portion and at least one deformation portion; and a second module comprising a measuring cell with a measuring cell body, wherein the measuring cell body is connected to an electrical measuring system.

  • the force introduction portion 118 carries, for example, a pulley 131, as used for example in cranes. About the pulley 131, the (weight) force is transmitted to the force introduction portion 118.
  • the deformation portions 122 are rotated from the solid material of the axle body 112 and milled. When a force 120 is applied, the greatest deformations occur in these areas (bending / compression / shear). These deformations are in turn converted by means of measuring cells 134 into electrical signals.
  • a measuring cell such as a strain gauge (DMS) is provided.
  • the measuring cell 134 is seated in a recess which extends in the radial direction, that is to say perpendicular to the plane of the drawing of FIG. 5, into the axle body 112.
  • the wiring of (not shown here) DMS is effected by bores, not shown here, which are located in the interior of the axle body 112, so that the signals can be tapped at an axial end of the axle body 112 via a terminal 132.
  • the radial recesses for the measuring cells 134 must be milled radially into the axle body 112 in a separate operation. The same applies to the holes, not shown, to wire the measuring cells 134.
  • the wiring of the load cells 134 itself is cumbersome since the cables must be routed through small diameter wiring bores to connect them to the terminal 132, for example.
  • Another problem is the sealing or closure of the measuring cells 134 with respect to the outside world.
  • the measuring cells 134 are exposed to external influences, such as, for example, impacts or changing weather. If a measuring cell 134 is not sufficiently sealed off from the outside world, water can penetrate into the measuring cell 134 and disturb the operation of the latter or even destroy it.
  • the radial depressions are usually relatively small in diameter or relatively deep, so that the bonding of foil DMS due to the small space available problematic and elaborately designed.

  • the measuring cell and its wiring can be mounted or prepared outside the axle body. Subsequently, the already wired measuring cell is introduced into the axle body, which represents a considerable simplification.
  • axle body surrounds the measuring cell body in the inserted state relative to the longitudinal axis in the circumferential direction.
  • the force to be measured usually acts essentially perpendicular to the longitudinal axis of the axle body, deformations can best be transferred to the measuring cell, if it is preferably completely surrounded by the axle body along its entire longitudinal extent in the circumferential direction.
  • the power transmission then takes place directly in the interior of the axle body, which increases the reliability of the sensor system, which is generally based on the shear or bending beam principle.
  • the axial bore is arranged concentrically to the longitudinal axis.
  • a force measuring sensor which is able to determine a direction of the force. Since the axial bore is located in the middle of the axle body, the symmetry required for a direction-dependent force measurement prevails. According to a preferred embodiment, the axial bore is in the region of the deformation section.
  • the mechanical deformation is greatest in the area of the deformation section. If the measuring cell is arranged exactly in this area of the axle body, the sensitivity of the force measuring sensor system increases.
  • the axial bore extends through the axle body.
  • the axial bore has axial sections of different diameters.
  • the axial bore may have a smaller diameter than the measuring cell in a central region relative to the longitudinal axis of the axle body. In this way, it is ensured that the measuring cell is not insertable into the central region of the axial bore. In the central region of the axial bore usually only slight mechanical deformations take place, so that the central region of the axle body for the measurement of forces, which is based on the bending beam principle, is relatively uninteresting.
  • the axial bore comprises a portion which is intended to receive the measuring cell and is conical.
  • the conical design of the axial bore allows, with a correspondingly formed measuring cell body, a surface connection between the measuring cell body and the axle body, when the measuring cell is inserted into the axial bore. The stronger the measuring cell body is pressed into the axle body, the better the surface connection and thus the better the transmission of power from the axle body to the measuring cell. This in turn increases the sensitivity and reliability of the entire force measuring system.
  • the measuring cell is formed dumbbell-shaped.
  • the dumbbell-shaped measuring cell body has two dumbbell heads and a bridge element, wherein the bridge element connects the dumbbell heads in the axial direction.

  • the bridge element between the dumbbell heads can be produced in a simple manner.
  • the dumbbell heads may for example be cylindrical, and preferably conical, so that the measuring cell body itself can be produced from round material. Round material is inexpensive and easy to store.

  • the opposite end faces of the dumbbell heads each have a recess for the positive reception of the bridge element.
  • the entire load cell can be chosen from a modular system of any type.
  • the modular construction of the measuring cell itself is particularly advantageous if the force measuring sensor system is applied to the bridge element by means of a sputtering technique.
  • the sputtering technique is difficult to apply to the bridge element, which manifests itself in the worst case in a not sufficiently homogeneous surface finish of the bridge element or the sensor produced by the sputtering technique.
  • platelets are preferably used as the bridge element.
  • the platelets can be easily inserted into corresponding recesses in the front sides of the commercial heads.
  • the wafer itself has a sufficiently large area to be able to use the sputtering technique satisfactorily.
  • the bridge element has a cross-shaped cross section.
  • the bridge element With a cross-shaped cross section, several force measuring sensors can be arranged on the respective surfaces of the bridge element. Surfaces lying in one and the same plane can be used to determine a force component in a first direction. The sensors disposed on the other plane may be used to determine a second force component that is oriented rotated 90 ° to the first force component. Furthermore, it is advantageous if the bridge element is square-shaped and hollow inside. With a square-shaped bridge element both (direction-dependent) bending forces and shearing forces can be measured excellently.
  • the use of a cylindrical bridge element is advantageous for the measurement of torsional forces.
  • a solid cylinder excellent torsional forces can be transmitted from one end face to the other end face.
  • the force measuring sensor is mounted on the outside of the cylinder in order to detect the mechanical deformation of the cylindrical bridge section well. The larger the radius of the bridge element, the lower the torsional rigidity, i. the torque increases.

  • the outer shape of the measuring cell module no longer necessarily has to be approximately identical to the shape of the axial bore in the axle module, since the force transmission (during a measurement) is no longer (exclusively) via the surface connection, but via the frictional connection between the two modules. A great advantage is therefore to be seen in the fact that the requirements for manufacturing accuracy are lower. Next, the installation is also facilitated.
