    A brush device for a small electric motor comprises an integrally formed commutator slide, a brush base and a terminal portion made of a thin material. A reinforcing piece is provided by bending the side edge of the base both to permit the brush device to be resiliently retained within a terminal insert hole formed in the motor case cover.

    专利说明:

    The invention relates to electrical engineering in terms of the design of brushing devices for microelectric machines. A brushing device for microelectromachines is known, containing a brush made integral with the brush base provided with an end portion protruding from the brush base, wherein the base Sci and the end portion are located in the mounting hole of the casing of the micromachine casing made of synthetic resin, the image of the surface of the mounting hole is made protrusions on both sides of the brush base and the support element is mounted along the base axis in such a way that the brush base rests elastically its central portion on the support member, and both edges - on said projections Til & | Marker attached to the casing body and inserting a bend with respect to three points of contact with the elastic material. However, because of the desire to reduce losses and friction between the brush and the collector, the 1st electrically conductive material is used as an elastic strain of the brush material, and the thickness of such a material must be about 0.08 mm, which reduces the working rigidity of the brush and decreases the reliability fastening brushes. The aim of the invention is to increase the reliability of attachment of the brush. The goal is achieved by the fact that the base of the brush is provided with a reinforcing element, which is formed by bending the edge of the base of the branch. Opposite to the end section, in this case the joining is bent longitudinally to the protrusions of the OP01 of the element and rests, at least in its central part, on the element indicated onopmrt. FMG 1 shows a casing of a micro electric machine for fastening brushes; 2 and 3c | etk of the twig device; on 4v1g. 4 - inaccurate device in pack “, type cnepexiH} in FIG. 5 is a section aa and FIG. 4} on the fng. 6 - section 1-B va f g. 4) in FIG. 7 is an in-line assembling device, top view. The brushing device for microelectromachines contains a brush 1, you {Eunyu in the form of a whole, with a base of 2 chains, equipped with.
    section 3 protruding from the base of the brush. The brush base and the horse section are mounted in the mounting hole 4 of the casing 5 of the housing of a microelectric machine made of synthetic resin. A protrusion 7 is made on the surface of the mounting hole 4 on both sides of the brush base, and the support element 8 is mounted along the base axis so that the brush base 2 rests elastically with its central part on the support element 8, and on both edges on the corresponding protrusion 7 The brush base 2 is provided with a reinforcing element 9, which is formed by bending the edge of the brush base opposite to the end section 3. The reinforcing element 9 is bent longitudinally by the projections 7 and the supporting element 8 and is supported at least by price With its main part on the supporting element 8, undercuts 10 and 11 can be provided on the generatrix b of the mounting aperture 5, the distance between which corresponds to the width of the reinforcing element, which additionally allows the reinforcing element 9 to be inserted into the grooves when mounting the brush. On the brush base 2, a cutout along the incomplete perimeter may be provided, the end 12 of which is bent (in the assembled brush device abuts the inner wall of the end mounting hole 4) and serves to prevent the brush base 2 from exiting hole 4. The device has an opening 13 for the micromachine shaft .
    When mounting the device, the brush base 2 with the end section 3 is inserted into the mounting hole 4 of the machine casing 5 and advances along the support member 8 and the side projections 7. After installing the brush base in the mounting hole 4, the central part of the brush base abuts one support surface 8, and the other surface of the base with both edges of the brush base rests on the corresponding protrusions 7, i.e. brush base. held at three points. In this position, the reinforcing element 9 not only strengthens and strengthens the brush base, but also increases the holding force of the brush base at three points. The fastening force is further increased when the cut and bent end 12 cuts into the inner wall of the hole 4 and is pressed into it. The brush can be even more securely fixed in the mounting hole if the reinforcing element 9 is pushed into the recesses 10 and 11 of the surface 6.
