Definitions

  • the present invention relates to a pulse generator according to the preamble of claim 1.
  • Such a pulse generator is known from DE-A 2 658 105.
  • the offset of the pulse diagrams is achieved in that the one contact spring of a contact unit has a cam and that the axis of rotation of the control disk does not coincide with the connecting line of the two cams.
  • the distance of the axis of rotation from the connecting line must be strictly observed, since the shape of the offset pulse diagrams depends on this. Therefore, on the one hand, this distance must be strictly observed and, in addition, the cams of the contact springs must be adjusted so precisely that the distance between the axis of rotation of the control disk and the connecting line of the two cams is also precisely observed.
  • the object of the present invention is to provide a structure of the pulse generator that does not require such a precise adjustment and / or does not require such high demands on the manufacturing tolerance.
  • An angular encoder is already known from DE-A 1 462 447, which has two control disks arranged side by side in parallel planes. A contact is assigned to each control disk and the two contacts are arranged opposite one another.
  • the known control disks are not of the same design, but the one control disk has only a single depression along about a quarter of the circumference thereof, so that a switching cam is formed over about three quarters of the circumference, whereas the other control disk has two such depressions distributed symmetrically on the circumference and therefore has two corresponding switching cams.
  • the contact springs 3, 4, 5, 6 each have a contact piece 9, 10, 11, 12 at the inner projecting end 8 and two contact springs 3, 4 and 5, 6 result in a contact 13 and 14, respectively.
  • the contact springs can be provided by the invention 3, 4 and 5, 6 are all used in one direction and have the same design.
  • the contacts 13, 14 or their contact springs 3, 4 and 5, 6 are provided at a distance from one another and between their inner contact springs 4 and 5 an insulating control disk 15 and 16 is rotatably supported for each contact 13 and 14.
  • the control disks 15, 16 are each in a different plane and, accordingly, the contact 13 or 14 assigned to a control disk 15 or 16 is also attached in the corresponding plane.
  • the control disks 15, 16 are preferably of identical design and are provided with a plurality of, preferably three to ten, switching cams 151 to 155 or 161 to 165 evenly distributed on the circumference. In addition, they are offset from each other by an angle a or a 'which is smaller (a) or larger (a') than half the central angle Z of two adjacent switching cams, e.g. B. between the switching cams 154 and 155 according to FIG. 1.
  • the two control disks 15, 16 expediently form a single component, for example a plastic injection-molded part.
  • the contacts 13, 14 are at such a distance from one another and from the axis of rotation 17 of the control disk 15, 16 that the cams 151 to 155 or 161 to 165, the inner contact spring 4 or 5 in a predeterminable range of rotation so far to the left or right deflects that their contact piece 10 or 11 touches the counter contact piece 9 or 12 and also deflects slightly.
  • the contact springs 3, 4 or 5, 6 bend and there is also a slight contact friction of the contact pieces 9, 10 and 11, 12.
  • the inner contact springs 4, 5 are expediently attached so that their legs 41 and 51 in the open position of the contacts 13 and 14 between two adjacent switching cams 151-152, 152-153 etc. and 161-162; 162-163 (as shown in the switching state of FIG. 1), etc., rest on these or on the surface spanned between the switching cams on the control disk 15 or 16.
  • the corresponding leg 41 or 51 can form a cogging torque with the switching cams or the surfaces, so that the control disc ben 15, 16 are each in a defined position in the rest position.
  • the control disks 15, 16 are non-positively connected to a pinion 18 and in particular consist of a single component, e.g. a molded plastic part.
  • the pinion 18 can be driven via a spur gear 19 which is pushed or shrunk onto a drive shaft 20 or which forms a structural unit with the drive shaft 20.
  • the drive shaft 20 is rotatably mounted in a bearing bush 21 of the housing part 1 and is fixed axially on the one hand by the pinion 18 and on the other hand by a locking washer 22.
  • the housing part 1 can preferably be sealed tightly by a cover 23.

Claims (5)

1. Générateur d'impulsions comprenant deux unités de contact (13,14) disposées parallèlement l'une à l'autre, qui peuvent être actionnées par un disque de commande comportant des cames de commutation (respectivement 151 à 155 et 161 à 165) également réparties sur la circonférence, pour engendrer deux formes d'impulsions pour la détermination d'un ajustement angulaire et/ou d'une vitesse de rotation, ainsi que du sens de rotation d'un entraînement couplé au disque de commande, ou pour commander un compteur- décompteur, les formes d'impulsions étant décalées l'une par rapport à l'autre et se recouvrant mutuellement, en fonction du sens de rotation du disque de commande, grâce à des ouvertures et fermetures décalées des deux unités de contact, caractérisé par la combinaison des caractéristiques suivantes:
- les unités de contact (13, 14) comprenant des ressorts de contact (3, 4; 5, 6) s'étendant en ligne droite sont agencées dans des plans différents;
- chaque unité de contact est pourvue d'un disque de commande (respectivement 15, 16) disposé dans son propre plan;
- les deux disques de commande (15, 16) sont constitués de polygones réguliers de même forme et parallèles l'un à l'autre, agencés sur un même axe (17);
