Definitions

  • the present invention relates to a screw device for applying a torque to a screw according to the preamble of claim 1. Furthermore, the present invention relates to a hand-held screw system, comprising such a generic screw device.
  • Such a device is for example from the US 2010/0269646 A1 out.
  • Screwdriving devices of the generic kind are generally known from the prior art, in particular industrial screwdriving technology.
  • the screw ie, in the context of the present invention context with a torque to be applied screw
  • Flat outputs are often used. These are - usually housed in a flat housing - gear units with a drive usually provided at one end and an opposite end-provided output on which then the screw, suitably solvable, can be attached.
  • the gearbox in the flat output housing often consists of a meshing and thus a torque transmission from the drive to the output realizing arrangement of gears, which, between the drive and output (which are often even provided as gears with corresponding external teeth) realize a 1: 1 translation, however, depending on the field of application, a great variety of variations and modifications of this technology, which are generally known and generically presupposed, are possible and known.
  • the object of the present invention is therefore to improve a screwing device for applying a torque to a screw according to the preamble of the main claim, in particular with regard to a measurement accuracy of the detection means for detecting a driven side acting on the screw side output torque, thereby in particular possible measurement errors or Measuring tolerances, which are caused by the involved gear, deflection and connection components, as far as possible to avoid, and nevertheless to enable a device which can be produced with little design effort, so cost and reliable, with a geometric compactness straight flat drive means, without sacrificing should be maintained at transferable maximum torques, compared to the generic state of the art.
  • the means for detecting the output torque acting on the screw on the output side associated with the Flachabriossstoffn in particular in such a way that they are provided on and / or in a (flat) housing the Flachabriossstoff.
  • 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 is to be understood as meaning that the helical toothed gear according to the invention and integrated in the torque transmission of drive and output is rotatably mounted about an axis of rotation, which axis of rotation then specifies the axial direction of the axial force.
  • 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 helical gear according to the invention (as well as then more intermeshing gears) so provided in a housing of Flachabretesstoff that respective axes of rotation parallel to each other and parallel Flat sides of the flat drive extend.
  • the axis of rotation of the helical gear (as well as the axes of rotation of the other gears, more preferably also axes of rotation of the drive and / or output module) perpendicular to a longitudinal extent of the Flachabriosstoff (or a Flachabretesstoff forming, elongated housing).
  • the flat abrasion means-in the plane of the flat side (s) or perpendicular to this-are angled and / or cranked. Also, other ratios than 1: 1 are possible.
  • 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 quality measurement, 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 screwing device according to the invention, in an otherwise known manner can convert this mechanical kinetic energy into electrical operating energy for the described functionalities.
  • the resulting advantage of independence from batteries or other wired energy sources is also evident.
  • FIG. 1 System- and equally contextual representation of the present invention, in the perspective view of the screwing device for applying a torque to a screw according to a first embodiment of the invention, comprising in a housing 30, 32 included flat output means 10, which at one end (output side) for cooperation with a screw 12 as (not part of the invention belonging) screw a suitable screw driving tool 14 drive.
  • a drive assembly 20 in the form of a first helical gear is formed on the flat driven means, which transmits torque (FIG. Fig. 2 ) is connected to the angle head 16, and in which ( Fig. 3, Fig. 4 ) the drive torque can be introduced via an integrally seated flange portion 22.
  • 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 output means via a square head or tool section 26 (FIG. Fig. 3, Fig. 4 ) and a rotatably connectable drive sleeve 28 ( Fig. 2 ) can be transferred to the screw.

  • such flat drive means are provided and suitable for transmitting a maximum torque of about 200 Nm; a typical efficiency of such a helical gear device is between about 80% and 90% (i.e., the ratio of a driven side torque to 24 relative to a driving side torque at 20) depending on the lubrication conditions and fine configuration of the gears.
  • Fig. 2 to 4 show that on the output assembly 24 directly adjacent (and with the output assembly meshing) gear 38 detection 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 longitudinal direction of the housing 30, 32 - as far as vertical to the plane of the figure Fig. 2 to 4 running - and by the action of the torsionally loaded helical toothing force) detect.
