Abstract
The utility model discloses a connection structure of a brush assembly and a mounting cover, which comprises the brush set and the mounting cover. A brush carrier of the brush assembly is fixed on the mounting cover. A carbon brush is penetrated into the brush carrier with an opening at the tail part thereof. A spring frame is arranged on the mounting frame. A torsion spring is arranged on the spring frame. The external end of the torsion spring extends to tail of the carbon brush to be elastically clamped on the carbon brush. A spacing slot is arranged on the lateral wall on the same side of the carbon brush and the torsion spring. A bending part substantially in parallel with movement direction of the carbon brush is provided at the end part of the torsion spring. A convex part corresponding to the spacing slot on the carbon brush is provided on the bending part. The torsion spring carries out elastic seizing and spacing, has subtle structure design, and optimizes product structure.
Description
Technical field
The utility model relates to brush assembly of electric and the mounting cover syndeton in the motor, comprises carbon brush, brush holder, brush spring and mounting cover.
Background technology
As Fig. 1, syndeton for existing a kind of brush assembly of electric and mounting cover 11, after together being installed on the mounting cover, brush assembly of electric and relative other parts middle commutator is threaded onto mounting cover centre bore 12, the carbon brush 13 of brush assembly of electric is because the effect of brush spring 14 has one section to stretch into the mounting cover central hole, this needs earlier the both sides carbon brush is pulled out just and can be penetrated when making commutator being passed the mounting cover centre bore, under existing structure, the carbon brush of both sides needs manual the pulling, it is extremely inconvenient that operation makes installing of commutator like this, influenced the efficient of installing.
The utility model content
Technical problem to be solved in the utility model provides a kind of brush assembly of electric and mounting cover syndeton, it can be spacing with the both sides carbon brush earlier when installing the centre commutator, make it not extend into the mounting cover centre bore, thereby the structure of product has been optimized in installing of convenient middle commutator.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: brush assembly of electric and mounting cover syndeton, comprise brush assembly of electric and mounting cover, the brush holder of brush assembly of electric is fixed on the mounting cover, carbon brush is through in the brush holder, it is characterized in that: described brush holder afterbody opening, on mounting cover, also be provided with a spring(-supported) mount, spring(-supported) mount is provided with a torsionspring, the outer end of torsionspring extends carbon brush afterbody and flexible being stuck on the carbon brush, and the sidewall of the side that described carbon brush is identical with torsionspring is provided with a stopper slot.
Preferably, the described torsionspring degree of depth that extends the carbon brush afterbody is not more than half of carbon brush width.
Improved, for the spacing operation of carbon brush during the commutator assembling in the middle of the better fit, described torsionspring end is provided with a basic kink parallel with the carbon brush direction of motion, kink be provided with one with the corresponding protuberance of stopper slot on the carbon brush.
Preferably, the stopper slot on the described carbon brush runs through whole carbon brush side, is convenient to processing and location fully.
Preferably, the stopper slot on the described carbon brush is a circular arc.
The utility model is owing to adopt technique scheme, when installing, middle commutator only need elder generation that the carbon brush at two ends is promoted from inside to outside, the deflection of torsionspring outer end slides to the side, protuberance on the torsionspring kink snaps in the stopper slot on the carbon brush, thereby carbon brush card jail is spacing, made things convenient for the installation of middle commutator.Torsionspring of the present utility model plays elasticity blocking and spacing effect simultaneously, and structural design is ingenious, has optimized product structure.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the syndeton schematic diagram of existing brush assembly of electric and mounting cover;
Fig. 2 is that the utility model brush assembly of electric is connected the structure-improved schematic diagram with mounting cover;
Fig. 3 is an I place zoomed-in view among Fig. 2;
Fig. 4 is provided with the structural representation sketch for the stopper slot of carbon brush;
Fig. 5 is the vertical view of Fig. 4.
Embodiment
As Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5, schematic diagram for the utility model brush assembly of electric and mounting cover syndeton, comprise brush assembly of electric and mounting cover 21, the brush holder 22 of brush assembly of electric is fixed on the mounting cover 21, carbon brush 23 is through in the brush holder 22, described brush holder 22 afterbody openings, on mounting cover, also be provided with a spring(-supported) mount 24, spring(-supported) mount 24 is provided with a torsionspring 25, the outer end of torsionspring 25 extends carbon brush 23 afterbodys and flexible being stuck on the carbon brush 23, the sidewall of the side that described carbon brush 23 and torsionspring 25 are identical is provided with the stopper slot 26 of a circular arc, the degree of depth that described torsionspring 25 extends the carbon brush afterbody is not more than half of carbon brush width, described torsionspring 25 ends are provided with a basic kink 27 parallel with the carbon brush direction of motion, kink be provided with one with the corresponding protuberance 28 of stopper slot on the carbon brush.Stopper slot on the described carbon brush runs through whole carbon brush side.
When middle commutator is installed, only need elder generation that the carbon brush at two ends is promoted from inside to outside, the deflection of torsionspring outer end slides to the side, and the protuberance on the torsionspring kink snaps in the stopper slot on the carbon brush, thereby carbon brush card jail is spacing, made things convenient for the installation of middle commutator.Torsionspring of the present utility model plays elasticity blocking and spacing effect simultaneously, and structural design is ingenious, has optimized product structure.
