Abstract
The utility model relates to a motor inner part, especially to a carbon brush assembly in a motor. The carbon brush assembly in the motor includes a carbon brush, a conducting wire, a spring and a circular copper sheet, wherein the carbon brush is a square-block structure, a side surface of the carbon brush is provided with a circular hole, one end of the conducting wire is fixed in the carbon brush, the conducting wire extends out from the circular hole, the other end of the conducting wire is welded on the copper sheet, and the spring sheathes the conducting wire between the carbon brush and the copper sheet. The carbon brush assembly in the motor provided by the utility model has the advantages of favorable conductivity, heat conductivity, and lubricity as well as high mechanical strength and excellent reversing spark restriction performance.
Description
Technical field
The utility model relates to parts in the motor, the carbon brush component in especially a kind of motor.
Background technology
Carbon brush is the device that transmits energy or signal between standing part and the rotating part of motor or generator or other rotating machineries, as a kind of sliding contact part, in many electric equipments, is widely used.The motor that has commutator because carbon brush not only plays conduction current, but also plays the role of changing, and because the rotation of rotor, brush rubs with commutative ring all the time, so carbon brush should have the instinct of certain mechanical strength and switching-over property spark.
The utility model content
The technical problem that the utility model will solve is: based on the problems referred to above, a kind of have good conductive, heat conduction, greasy property are provided, the interior carbon brush component of motor that mechanical strength is high.
The utility model solves the technical scheme that its technical problem adopted: the carbon brush component in a kind of motor; Comprise carbon brush, lead, spring and circular copper sheet, described carbon brush is a box structure, offers a circular hole on the side of carbon brush; One end of described lead is fixed in the carbon brush; Lead passes through circular hole, and the lead other end is welded on the copper sheet, and string has spring on the lead between carbon brush and the copper sheet.
Further; Can move by easy on and off in the brush carrier in order to guarantee that carbon brush is packed into; And avoid swinging because of excesssive gap produces among carbon brush and the brush carrier, the size of described carbon brush matches with the size of the brush carrier guide groove of splendid attire carbon brush, and the inwall gap of carbon brush and brush carrier guide groove is 0.1～0.3mm.
The beneficial effect of the utility model is: the utlity model has good conductive, heat conduction, greasy property, also have the instinct of excellent mechanical intensity and switching-over property spark.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the structural representation of Fig. 1 on the A-A direction.
Among the figure: 1. carbon brush, 2. lead, 3. spring, 4. copper sheet, 5. circular hole.
Embodiment
Combine accompanying drawing that the utility model is done further detailed explanation now.These accompanying drawings are the sketch map of simplification, the basic structure of the utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
Carbon brush component in a kind of motor shown in Fig. 1～2 comprises carbon brush 1, lead 2, spring 3 and circular copper sheet 4, and carbon brush 1 is a box structure; Offer a circular hole 5 on one side of carbon brush 1, an end of lead 2 is fixed in the carbon brush 1, and lead 2 passes through circular hole 5; Lead 2 other ends are welded on the copper sheet 4, and string has spring 3 on the lead 2 between carbon brush 1 and the copper sheet 4, wherein; Carbon brush 1 is packed in the brush carrier guide groove of splendid attire carbon brush 1, is connected in the rotating shaft.
With above-mentioned desirable embodiment according to the utility model is enlightenment, and through above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the specification, must confirm its technical scope according to the claim scope.
