Definitions

  • the invention relates to a contact element holder for electrically contacting a rotor, in particular a brush holder for commutator or slip ring machines, according to the preamble of claim 1.
  • Such a contact element holder is known from JP 57 0000 46 p , JP 2001 245 458 A discloses a contact element holder in which the brush is connected to the brush holder via springs.
  • commutator brushes of commutator machines e.g. DC small motors
  • Kommutatorunrund causes due to Kommutatorunrund phenomenon, jumps in the transition from one to another Kommutatorlamelle u.ä.
  • Operating noise that is transmitted to the machine housing via the brush holder and radiated by the latter.
  • noise-decoupled brush holders are used.
  • the decoupling elements between the carrier and brush quiver are formed as resilient webs, which connect a brush quiver firmly receiving intermediate carrier with the carrier.
  • Subcarrier and carrier are formed as plates, which lie in a common plane.
  • the meandering webs are either in the plane of the plates or perpendicular to the plates, in the latter case have the meander in the axial direction of the commutator.
  • the two plates and the webs are designed as a one-piece molded part.
  • the contact element holder according to the invention with the features of claim 1 has the advantage that a rotational decoupling of the quiver around the rotor axis without additional degrees of translational or rotational nature is achieved and thereby in use in commutator required for a good commutation, centered position of the commutator over a not noise-decoupled, rigid brush holder.not deteriorated.
  • the responsible for the brush noise Reibwertschwankeptept between commutator and commutator cause exclusively a rotatory rotation of the quiver and thus do not influence the centered position of the commutator brushes.
  • the contact element holder according to the invention can be realized structurally very simple in that according to a preferred embodiment of the invention, at least three decoupling elements are provided and each decoupling element has only one degree of freedom, wherein the decoupling elements are arranged between the carrier and quiver so that the degree of freedom of each decoupling element in the tangential direction Rotor runs.
  • the decoupling elements are offset by preferably the same rotation angle in the circumferential direction against each other, so arranged in a star shape.
  • the quivers are arranged on an intermediate carrier and carrier and intermediate carrier are interconnected by the decoupling elements.
  • Carrier and intermediate carrier are designed as Isolierstoffplatten, which lie in a common plane, and the elastic webs extend at right angles to the plates.
  • This constructive design with "standing decoupling elements" of the contact element holder has a small footprint, which is advantageous for the accommodation of additional suppression elements.
  • the decoupling elements are when spraying the one-piece contact element holder in Entformungscardi, so that no additional cross slide are required in the injection mold.
  • the in Fig. 1 shown in plan view brush holder for a small DC motor used as a commutator machine as an example of a contact element holder has a carrier 11 having a square recess 12 in the middle, in which an intermediate carrier 13 rests.
  • Carrier 11 and intermediate carrier 13 are formed as disc-shaped insulating plates and connected to each other via a total of four elastic decoupling elements 14.
  • the intermediate carrier 13 has a circular passage opening 15 for the passage of a commutator, not shown here, of the direct current small motor.
  • the brush holder has two commutator brushes 16, which are accommodated axially displaceably in a brush quiver 17 extending in the direction of the passage opening 15 and are pressed onto the commutator in the mounted state by means of brush pressure springs (not shown here).
  • the electrical connection strands of the commutator brushes 16 are designated by 18.
  • the brush holder 17 are mounted on the intermediate carrier 13.
  • two abstrebende arms 131 are provided on the intermediate carrier 13, which eino with play in corresponding side extensions 121 of the recess 12.
  • the brush cases 17 are made of metal and fixed on the arms 131.
  • the brush holder 17 can also be made of insulating material and are then made in one piece with the insulating plate of the intermediate carrier 13 by spraying, so that the arms 131 omitted.
  • the four decoupling elements 14 are arranged offset by the same circumferential angle staggered around the passage opening 12 in the intermediate carrier 13 and on the one hand between the brush bags 17 on the intermediate carrier 13 and on the other hand fixed to the carrier 11.
  • Each decoupling element 14 has only one degree of freedom and is arranged so that this degree of freedom in the tangential direction to the commutator, so to the commutator receiving passage opening 15 extends, of course, the brush holder is mounted in the motor housing, that the axis of the passage opening 15 in the intermediate carrier 13 coincides with the commutator axis. Due to the star-shaped arrangement of the decoupling elements 14 with a tangentially directed degree of freedom, the intermediate carrier 13 with the brush bags 17 fastened thereon can only execute a limited, rotary pivoting path around the commutator, so that the commutator brushes 16 pressing onto the commutator are rotationally decoupled. Other degrees of freedom, namely two rotational and three translational, are not present or are negligible.
  • the decoupling elements 14 are realized by means of elastic, flat webs 19, each of which is located in a plane radial to the commutator or to the axis of the passage opening 15.
  • Fig. 3 is such a flat bridge to see in plan view. It has a U-shape with legs 191, 192 and a yoke 193 connecting the legs 191, 192.
  • One leg 191 is attached to the carrier 11 and the other leg 192 to the intermediate carrier 13.
  • the webs 19 injected during injection of the carrier 11 and intermediate carrier 13 integrally with these, at the same time the brush holder 17 are mitangespritzt and thereby the separate arms 131 omitted on the intermediate carrier 13.
  • the webs 19 are at right angles from the carrier 11 and intermediate carrier 13 forming insulating plates, so that they are in spraying in Entformungscardi and no additional cross slide are required in the injection mold.
  • a plan view to be seen brush holder according to a further embodiment is designed according to the same basic principle.
  • the decoupling elements have only one degree of freedom and are arranged between the carrier 11 and intermediate carrier 13 so that the existing degree of freedom in the tangential direction to the commutator, so that the brush holder 17 can perform with the therein Kommutatorbürsten only a limited rotation about the commutator and all other degrees of freedom of the subcarrier 13 are practically nonexistent.
  • the intermediate support 13 is formed as a circular insulating plate, which rests with play in the likewise circular recess 12 of the carrier 11 formed as insulating material.
  • each decoupling element 14 is again designed as a flat, elastic web 19 which is U-shaped and projects at right angles from the carrier 11 and intermediate carrier 13 forming insulating panels. In the same way as in Fig. 1 and 3 Here, too, the web 19 with its one leg 191 with the carrier 11 and its other leg 192 with the intermediate carrier 13 is firmly connected.
  • the yoke 193 is different than in Fig. 3 arched.
  • construction and operation of the modified brush holder according to Fig. 2 identical to the brush holder in Fig. 1 so that reference is made in this respect to the above statements.
  • Matching components of the brush holder according to Fig. 2 are provided with the same reference numerals.
  • the contact element holder described by way of example as a brush holder for a commutator machine for producing an electrical connection to a rotor, in the exemplary embodiment to the commutator, is also used in so-called slip ring machines, e.g. Synchronous machines can be used with slip ring rotors.
  • so-called abrasive brushes are inserted into the quivers instead of the commutator brushes, which rest spring-loaded on at least one slip ring instead of on a commutator.
  • the contact element holder described can be found everywhere where an electrical contact between a contact point, a current-carrying component and a rotating, current-carrying component (rotor) is to be produced.
