Definitions
- the invention relates to a brush holder for a power transmission unit of a dynamo-electric machine having a commutator, in particular for an electric motor, wherein the brush holder, which is in particular made of metal, has guide regions for guiding a brush which can be displaced for longitudinal extension, which is designed in particular as a multilayer carbon brush. and there is a gap between the guide portions and the brush across the length of the brush.
- the invention relates to a brush for the brush holder, a power transmission unit for a dynamo-electric machine with the brush holder and / or the brush or a dynamo-electric machine with such Stromübemagungsaku and a method for producing the brush holder.
- the power transmission unit is a so-called sliding contact system, which ensures an electrical connection between a power supply or external connections of the dynamo-electric machine and windings of a rotor.
- a sliding contact system which ensures an electrical connection between a power supply or external connections of the dynamo-electric machine and windings of a rotor.
- an arrangement with spatially fixed brushes which usually consist of coal and are in sliding contact with a rotatable commutator provided.
- the commutator consists of individual electrically conductive blades, which are connected to the windings of the rotor. On the slats, the brush slides along to make an electrical contact between the slats and brush.
- a brush is slidably guided in a spatially fixed brush holder, which is also referred to as a brush guide or brush sleeve.
- the brush is loaded in the direction of the commutator, ie in a radial direction, with a spring.
- a substantially constant pressure force of the brush is ensured on the commutator.
- the brush is tracked by the spring force within the brush holder to compensate for wear of the brush.
- multi-layer carbon brushes are used in the known Stromübemagungsakuen.
- Such multilayer carbon brushes have high-resistance or electrically non-conductive layers between individual carbon layers for reducing so-called cross-currents or short-circuit currents within the brush.
- Such cross-currents can occur when a brush is in contact with two adjacent fins of the commutator or when a brush or individual brush layers come into contact with an electrically conductive brush holder such that a current can form across the brush.
- Electrically conductive brush quivers which are usually made of metal, are frequently used in dynamo-electric machines because of their low-cost production.
- such brush holder In order to avoid contact between the brush and the brush holder, whereby a cross-flow can form in the brush, such brush holder have a relatively large lateral clearance between the brush and the brush holder.
- a carbon brush of an AC universal motor of a washing machine in its transverse extent is usually 0.04 to 0.05 mm narrower than the inner guide region of the carbon brush holder assigned in this transverse extension.
- the relatively large clearance between the carbon brush and the carbon brush case is therefore 0.02 to 0.025 mm on both sides in such a case.
- a disadvantage of the great game is that during operation of the dynamo-electric machine produces a noise. As soon as the brush strikes a lamellar edge, the brush strikes against the inner walls of the quiver. In this case, the brush strikes twice per blade.
- a known solution to avoid noise provides, in addition to edit the lamellar commutator, for example, by so-called pimples or fine grinding.
- pimples or fine grinding When reworking the commutator again dust particles that need to be removed consuming, so that these dust particles in turn can not cause a brush terminals.
- a brush quiver which is particularly suitable for guiding multilayer carbon brushes and has a distance transversely to the carbon brush to be guided, is known from US Pat DE 101 57 604 A1 or the US-A-3983432 known.
- the brush quiver is made of tinned sheet steel and covered with an insulating layer.
- the insulation layer applied in the brush quiver serves to avoid a short-circuit current or cross-current between individual layers of a multilayer carbon brush.
- a paint such as phenolic resin, epoxy resin or polystyrene is applied to the steel plate of the carbon brush holder. When using such Insulation between the carbon brush holder and the multilayer carbon brush, the clearance between the brush holder and the carbon brush can be tightly tolerated.
- a disadvantage of the small game is that the brush dust that enters the gap, can accumulate in the space, causing the brush jammed in the brush holder or the layers of the brush are shorted by unburned brush dust. Moreover, such an insulating layer can not be stressed as much thermally and mechanically as a pure metal guide.
- the invention is therefore based on the problem of designing a carbon brush holder and / or a carbon brush or a resulting power transmission unit for a dynamo-electric machine such that a brush of the power transmission unit does not cause any noise and / or no cross currents can form in the brush , Furthermore, a method for producing a corresponding brush holder is to be provided.
- the power transmission unit should be such that no cross currents are caused in the brush by the brush dust generated during operation or the brush can not jam in the brush holder, and on the other hand, the power transmission unit or its components are inexpensive and easy to produce.
- this object is achieved by the features of claim 1 of a brush holder, the independent claim 10 a carbon brush, the independent claim 12 of a power transmission unit and the independent claim 13 of a dynamo-electric machine.
- Advantageous embodiments of the invention are represented by the features of the subclaims.
- the brush holder of a dynamo-electric machine with a commutator
- the brush holder has guide regions for guiding a brush displaceable to the longitudinal extension and there is a gap between the guide regions of the brush holder and the brush transversely to the longitudinal extension of the brush. in such a way that in a front of the commutator facing the guide area, the distance in at least one transverse to the brush longitudinal extent is less than in a rear facing away from the commutator guide area.
- the play between the brush and the brush holder in the area which faces the commutator can be limited so far that the brush is guided in this area almost free of play.
- a beating of the brush on the brush holder during normal operation of the power transmission unit is prevented when the game is limited in an orientation that is tangent to the commutator.
- a specified according to DIN 43008 game for a power transmission unit can be maintained and even below.
- An education of noise by hitting the brush can thus be effectively prevented.
- experiments have shown that in such an embodiment, a large transverse play between the rear commutator facing away from the guide area and the carbon brush can be present without the brush strikes in operation on the quiver.
- the great game in the rear guide area is advantageous because there is sufficient space for any resulting brush dust is available. A so-called jamming of the brush in the brush holder can be effectively excluded.
- such a design of the brush holder allows easy mounting of the power transmission unit, since the brush during assembly of the power transmission unit can be easily inserted into the brush holder.
- the brush holder in the front guide region has a decisive distance for guiding the brush or a clearance between the brush and the brush holder, which is lower in the front guide region of the brush holder by at least 0.005 mm than in the rear guide region.
- a sufficiently large clearance is present in the rear guide region of the brush holder when the brush is guided virtually free of play in the front guide region.
- at least a 0.005 mm larger clearance in the rear guide area sufficient to prevent jamming of the brush in the brush holder when operating in a dynamo-electric machine can be avoided.
- a guide plane which is formed by the front and rear guide region of a first wall of the brush holder, is inclined to a guide plane which is formed by the front and rear guide region of a second wall, wherein the second wall opposite the first wall.
- previous production facilities for brush quiver can continue to be used because, for example, the inventive slope of opposite wall portions of the brush holder can be produced by simply pressing in parallel wall sections or guide areas of conventional brush quiver. Therefore, the brush holder can be further manufactured in one piece.
- At least one wall of the brush holder which guides the brush axially or parallel to the axis of rotation of the commutator, according to a further development of the invention in a front region of the brush holder at least one aperture and / or channel.
- the opening in the front region of the brush holder is designed as a slot which is open at the commutator end.
- the breakthrough of the brush holder is designed grid-shaped.
- a very large opening area can be realized by a plurality of openings in the brush holder, without the stability of the brush holder is limited by such breakthroughs, since the remaining webs between the openings still have sufficient strength.
- Such a design of the brush holder is used for rapid escape of brush dust.
- the inwardly directed formations of the front guide region of the brush holder are designed in the form of at least one bead and / or one pimple.
- Such embodiments can be particularly simple, for example by embossing produce.
- It is also advantageous in this embodiment of the brush holder that in a closer environment outside the thus formed front guide region of the brush holder, a relatively large clearance or a distance between the brush and the brush holder is possible. Thus, brush dust particles that get between the brush and brush quiver, escape well again.
- the brush holder in the front guide region on a high-resistance or electrically non-conductive layer is formed on a high-resistance or electrically non-conductive layer.
- a layer extends over the entire guide region of a brush holder.
- a brush quiver according to the embodiment of the invention can be made more cost-effective than the previously known brush quiver, since only the front guide portion of the brush holder has an electrically non-conductive layer.
- the invention also relates to a brush which serves for use in the brush holder according to the invention.
- the advantageous embodiment of the brush is characterized in that regions of the brush, which may touch the front guide region of the brush holder during a proper use for operating a dynamo-electric machine, have a high-resistance or electrically non-conductive layer. By such a layer, the formation of transverse currents in the brush can be prevented. Since only portions of the brush must have the electrically non-conductive layer, insulation material can be saved compared to full-surface coated brushes.
- the electrically non-conductive layer of the brush consists of an insulating varnish.
- Such a paint can be easily applied to the brush, whereby the brush is only slightly more expensive.
