Definitions
- the invention relates to a plastic hammer brush holder arrangement according to the preamble of claim 1; such an arrangement or a single hammer brush holder of this type are known from EP-B1-0 175 993 and DE-C3-28 14 009.
- the known hammer brush holders are injection molded as a one-piece hard plastic part with at least one brush holder on one end and a bearing holder on the other end of a brush support arm.
- a brush which grips the commutator of a commutator motor with its other free end, is inserted into the brush holder and contacted with a power connection.
- the brush support arm is pivotally suspended from a brush holder via the bearing mount in such a way that, on the one hand, e.g. under spring tension, with its brush-side end pressed against the surface of the commutator, on the other hand, the unevenness can be followed when grinding the commutator surface without interrupting the contact.
- the known hammer brush holder arrangement can give rise to undesirable operational noises which have previously been attempted to counteract by special brush holder or commutator constructions and thus by means which are too expensive for a mass product.
- the plastic hammer brush holder arrangement according to the invention makes it possible to achieve a substantial noise reduction by simply sheathing, in particular overmolding an otherwise unchanged component with an elastic rubber material or thermoplastic elastomer, by not only insulating the radiation of noise, but also, surprisingly, the generation of noise Vibration noise in the walls of the hammer brush holder adopted unchanged is damped.
- FIG. 6, 7 show a single known brush support arm 5, again not provided with a jacket, which has a cutting-shaped bearing 51 at one end and a brush holder 56 at its other end, into which a brush 7 is clamped.
- a suppressor choke 11 is arranged on the back of the brush, and its terminal ends 11.1; 11.2 are clamped in elastic slot-shaped suppressor choke holders 53; 54, which are integrally molded onto the brush support arm 5 and are thereby held in an advantageous and simple manner.
- the brush-side connection end 11.1 of the suppressor choke 11 is clamped to a connection 11.3, which through a brush connection opening 57 in the brush support arm 5 reaches into the brush holder 56 and is contacted there with the brush 7.
- FIG. 1-5 show in different views or sections and partial sections the embodiment of a single brush support arm 5 described above with reference to FIG. 6,7, which, however, is provided according to the invention with a casing 9 made of a rubber material or thermoplastic elastomer.
- this sheathing 9 can be preformed as a profile part and then clamped or snapped onto the brush support arm 5 known per se or sprayed onto the brush support arm 5 known per se in still further manufacturing simplification.
