Definitions

  • the present invention relates to an impulse generator according to the preamble of claim 1.
  • Such a pulse generator designed as a digital angle measuring device is known from DE-GM 80 05 990. There, contact springs are arranged on a concentric circle. No information is given on the configuration of the conductive grid. It is also an inductive angle measuring device.
  • An electromechanical pulse generator is known from DE-OS 31 36 598.
  • a middle contact spring is deflected by a toothed washer and the contact thereof is pressed against a counter contact of a second contact spring. Due to the relatively low pressing speed, especially when individual impulses are emitted, a one-time contact, i.e. a single impulse, is often difficult to achieve.
  • the object of the present invention is to achieve an electromechanical pulse generator in such a way that it is simple to manufacture and suitable for rough operation, and enables flawless contact-free operation.
  • a cup-shaped housing part with an integrally formed or attached bearing bush 2.
  • a drive axle 3 is rotatable and immovably supported by a locking washer 4.
  • the drive axle 3 is provided with a drive pinion 5 and an inwardly projecting bearing pin 6.
  • a rotor 7 is mounted on the journal 6 and rotatably mounted.
  • the side of the rotor 7 pointing to the drive pinion L 5 is provided with a pinion line 8 or rigidly coupled thereto.
  • Drive sprockets L 5 and RitzeL 8 are operatively connected via a rigidly coupled, in particular one-piece gear pair 9, 10 formed from two spur gear wheels.
  • the pair of gearwheels 9, 10 is rotatably mounted on a bearing shaft 11 which is integrally formed on or attached to the housing part 1.
  • the spur gear 9 is smaller than the drive pinion 5 and the spur gear 10 is larger than the pinion 8.
  • the housing part 1 is expediently rectangular or square and the bearing axis 11 is provided in the direction of a corner 12.
  • the surface 13 of the rotor 7 is provided with a conductive layer 14, which has a coherent grinding ring running concentrically to the drive axis 3 with rectangular or trapezoidal teeth 16 projecting inwards on a likewise concentric circular path K 1 and projecting laterally outwards on one outer circular path K 2 arranged rectangular or trapezoidal teeth 17 forms.
  • the conductive layer 14 can be applied directly to the rotor 7 or, as in the exemplary embodiment, can be provided on a special, thin insulating disk 18, for example in the manner of the printed circuit.
  • This insulating disk 18 lies in a flat depression 19 of the surface 13 of the rotor 7.
  • the insulating disk 18 is secured against rotation by a recess 20 in the insulating disk 18 and a lug 21 which engages laterally in the recess 19 on the rotor 7.
  • the number of inner teeth 16 and their angular pitch ⁇ is equal to that of the outer teeth 17 and that of the locking cams 23 provided on the rotor 7, in particular on its end face 22 and in particular perpendicular to this elastically deflectable locking fingers 24 together.
  • the locking fingers 24 are in the diametrically opposite corners 25 and 26 are arranged so that the forces acting on the drive shaft 3 and the rotor 7 cancel each other out.
  • Contact springs 28, 29, 30 pressing or pressing on the surface 13 of the rotor 7 are molded or inserted into a lower housing wall 27, the contact spring 28 being assigned to the outer teeth 17, the contact spring 29 to the slip ring 15 and the contact spring 30 to the inner teeth 16 is.
  • the contact springs 28, 29, 30 carrying fixed contacts are expediently arranged approximately perpendicular to the diameter of the rotor 7 and their contact points 31, 32, 33 preferably lie at least approximately on a straight line, in particular on or near the diameter D.
  • the contact point 32 acts as a grinding Fixed contact and each contact point 31 and 33 as ImpuLs fixed contact.
  • the contact points 31 and 33 or the latching cams 23 are arranged such that when the or a latching finger (s) 24 is latched, the contact points 31 and 33 do not contact a tooth 17 or 16 between two latching cams 23.
  • the teeth 16 or their tooth flanks on one side are phase-shifted relative to the teeth 17 or their tooth flanks on the same side by an angle between> 0 ° and ⁇ 180 °, so that when rotating from the phase shift in a manner known per se, the direction of rotation of the rotor 7 can be derived.
  • Adjustment of the offset of the teeth 16, 17 or their tooth flanks against one another can also the contact springs 28 and 30 are arranged so that the contact points 31 and 33 cause this phase shift, or both the teeth 16, 17 or their tooth flanks and the contact points 31, 33 can be phase-shifted with respect to one another such that the pulses generated by 0 0 and ⁇ 180 0 are offset.
  • the offset of the impulse flanks can also be brought about by using a different tooth width of the teeth 16 compared to that of the teeth 17. It is essential that in one direction of rotation of the rotor 7 a tooth 16 or 17 is contacted earlier than the other tooth 17 or 16.
  • the cup-shaped housing part 1 can be closed by a further housing part 34, which can also be cup-shaped, and both can e.g. be locked together in the closed state by a locking element 35 on the housing part 1 and / or 34.
  • the housing rear part 27 carrying the contact springs 28, 29, 30 can be designed as a strip and can be inserted between the two housing parts 1 and 34. This facilitates the adjustment of the contact springs 28, 29, 30 or the generation of the pretensioning thereof.
