- these detection means associated with the flat driven means are designed in such a way that they can detect an axial force acting on a helical gear wheel connecting the drive and the output of the flat drive means and then provide the detected axial force for preferably electronic signal evaluation.
- axial force should be understood to mean that the toothed gear wheel according to the invention and rotatably mounted in the torque transmission of input and output is rotatably mounted about a rotation axis, which axis of rotation then dictates the axial direction of the axial force
- helical gearing of the gear used according to the invention and thus the other gears or sprockets or gears meshing therewith
- an additional, acting along the defined axial direction Force component is generated, which generates a force on the gear, this drives out of a purely flat, flat gear assembly between the drive and output.
- This force then acts against the detection means according to the invention, which can cause the adhesion to the gear along the axial direction either directly on a toothed edge of the gear or on a suitable shaft portion of the gear rotatably supporting (separate or integrally ansitzenden on the gear) shaft.
- the detection means it is preferred on the one hand to realize this as a piezoelectric force sensor or by means of a strain gauge arrangement.
- Such arrangements are, even in a compact form and with high measurement quality, available from specialized manufacturers and can be structurally simple to provide axial-positive cooperation with the helical gear or integrate into a housing of Flachabretesstoff.
- electrical power supply means for such electronic interface or Signalaufleungsmittel allow such, wireless, self-sufficient and suitably flexible functionality, wherein, in addition to about a battery solution for the electrical energy supply, in addition to further developing an electric generator solution into consideration comes, which, advantageously the rotational movements of the transmission components involved inevitably occurring in the screw device according to the invention, in an otherwise known manner, this mechanical kinetic energy can convert into electrical operating energy for the described functionalities.
- This mechanical kinetic energy can convert into electrical operating energy for the described functionalities.
- the resulting advantage of independence from batteries or other wired energy sources is also evident.

- a drive assembly 20 in the form of a first helical gear is formed on the output drive means, which is connected with the angular head 16 in order to transmit torque (FIG. 2), and into which (FIG. 3, FIG a one-piece ansitzenden flange portion 22 can be introduced.
- an output assembly 24 is again provided in the form of a helical gear which transmits the output torque to be provided by the flat driven means via a square head or tool section 26 (FIG. 3, FIG. 4) and a drive sleeve 28 (FIG. Fig. 2) can be transferred to the screw.
- a meshing sequence of intermediate, each helical gears 34, 36, 38 is provided so that between the drive assembly 20th and the output assembly 24 here is a gear ratio 1: 1 realized; as well as these two assemblies are the intermediate gears 34 to 38 each axially parallel to each other and linearly along a longitudinal extent of the housing 30, 32 arranged rotatably mounted in this.
- such flat drive means are provided and suitable for transmitting a maximum torque of about 200 Nm; a usual efficiency of such a helical device is, depending on the lubrication conditions and fine design of the teeth, between about 80% and 90% (ie the ratio of a driven side torque to 24 based on a drive-side torque to 20).
- FIG. 2 to 4 show that at the output assembly 24 directly adjacent (and with the output assembly meshing) gear 38 detecting means are provided which an acting on the gear 38 axial force (ie one along the axis of rotation of the Gear 38 and corresponding perpendicular to a direction of longitudinal extension of the housing 30, 32 - so far vertical to the plane of FIG. 2 to 4 running - and by the action of the rotationally loaded helical toothing force) detect.
- gear 38 axial force ie one along the axis of rotation of the Gear 38 and corresponding perpendicular to a direction of longitudinal extension of the housing 30, 32 - so far vertical to the plane of FIG. 2 to 4 running - and by the action of the rotationally loaded helical toothing force
- the gear 38 has axially integrally abutting shaft portions 40, 42 (and then via disc rings 44, 46, respectively, to the respective housing shells Forming 32 or 30 pivot bearing), axially at one end associated with a force sensor 48, which receives a axial force of the gear 38 (ie along the axis 52 in the image plane of FIG. 8 up) via a sensor-side bearing / disc assembly 50 and axially from the other end of a sensor cover 54 is supported, which in turn is fixed by the screw connection shown on the upper cover shell 30.
