Definitions

  • the tap is denoted overall by 10 - it consists of a block 11, which is representative of all conceivable storage and assembly forms, which can be driven by any machine part, the actual value adjustment of which by a highly precise voltage signal must be mapped, as well as from the actual grinder element, here consisting of a plurality of grinder fingers 12 arranged side by side and consisting of a suitable noble metal alloy, which are fastened at 13 to the bearing block 11.
  • the resistance path the potential of which is picked up by the tap during its movement and is usually to be transmitted to a parallel collector or return path, is designated by 14.
  • each wiper element in the idle state is particularly advantageous if it is not placed on the web to be contacted. Due to the characteristic bending curvature in the idle state, when the elastic contact force is maintained on each longitudinal part element 61 of the grinder, a force results which overall leads to the fact that in the installed state of the tap the grinder elements run practically completely straight from their clamping point to the bent end hook, So that it is possible to get significantly closer to the resistance path with the tap, to drastically reduce the distance of the clamping, which leads to tilting moments, vibrations, digging in or braking or to increased frictional losses, and the displacement forces acting on the tap, which ultimately occur in the contact zone between the end hook and the resistance track, as close as possible to them. Long-term tests have shown that this can be used to control a large number of vibration problems and dynamic effects that previously led to serious damage.
  • a preferred embodiment of the present invention therefore consists in the fact that, according to the striking and possibly exaggerated representation of FIG. 2, the individual wiper fingers and thus all parallel wiper fingers follow this shape in their entirety in the rest state, are bent in a pre-curved curve shape, and so, that they are with With respect to the resistance track on which they later slide, they are concave, ie they are bulged upwards.
