Embodiment
Below, with reference to accompanying drawing, execution mode of the present utility model is described.In addition, present embodiment does not limit the utility model.
Fig. 1 is the end view of the broken section of the brush motor 10 of the brush retainer assembly possessed in execution mode of the present utility model.Brush motor 10 possesses these two end caps of the end cap B 12 be made up of steel plate and the end cap A 11 be made up of synthetic resin, and the shape of the roughly cup-shaped of above-mentioned end cap B 12 in a side opening, above-mentioned end cap A 11 is configured at the peristome of end cap B 12.End cap A 11 is anchored on end cap B 12 by multiple hold-down screw.
End cap B 12 keeps in inside being fixed with excitation member 13.And the armature 14 with commutator 16 is configured to the central part of through excitation member 13, and this armature 14 is rotatably kept fixing by pair of bearings 15.In addition, pair of bearings 15 is kept by end cap A 11 and end cap B 12 respectively.
Fig. 2 A is the outside drawing of the shape of the brush retainer assembly 30 represented in execution mode of the present utility model.Fig. 2 B is the sectional view of the shape representing the shape tube retainer portion 20 of this brush retainer assembly 30 and the shape tube 22 after anti-flake (Japanese: order け stops め タ Block) 22a is bent.
End cap A 11 has a pair shape tube retainer portion 20 as shape tube retainer.Shape tube retainer portion 20 remains fixed in inner side by utilizing steel plate to be formed as roughly rectangular shape tube 22.Shape tube 22 includes carbon brush 21 in inside.In addition, in each side of the shape tube retainer portion 20 of shape tube 22 and end cap A 11, shape tube 22 place is provided with brush spring slits portion 22c, end cap A 11 place is provided with brush spring slits portion 20a.On the other hand, maintain torsion brush spring (Japanese: ト ー シ ョ Application Block ラ シ バ ネ) 23 at end cap A 11 place, torsion brush spring 23 is configured to slide in brush spring slits portion 20a, 22c.And carbon brush 21 is configured to the commutator 16 being crimped on the armature 14 configured at the central part of brush motor 10 by torsion brush spring 23 with suitable load.Brush retainer assembly 30 is included in the structure of torsion brush spring 23 that inner side includes the shape tube 22 of carbon brush 21, a pair shape tube retainer portion 20 being formed at end cap A 11 and kept by end cap A11.
Fig. 3 is the shape tube retainer portion 20 of the end cap A of the brush retainer assembly represented in execution mode of the present utility model and the outside drawing of the relation of shape tube 22.Fig. 4 A is the outside drawing of the details of the shape tube retainer portion 20 representing this brush retainer assembly 30.Fig. 4 B is the end view representing the brush spring slits portion 20a of this shape tube retainer portion 20 and the shape of sheet slit (Japanese: タ Block ス リ ッ ト) 20c.
As shown in Figure 3, shape tube 22 is inserted into shape tube retainer portion 20 along the direction of arrow.
At the inner peripheral surface of the shape tube retainer portion 20 of end cap A 11, be respectively provided with two protuberance 20b (with reference to Fig. 4 A) at the side surface part 20sa and the side surface part 20sc place relative with this side surface part 20sa that are provided with brush spring slits portion 20a.Protuberance 20b is arranged at the position of the corner close to shape tube retainer portion 20 inner circumferential side.In addition, protuberance 20b has the shape of the wire that the direction to the arrow of Fig. 3 extends.By these four protuberance 20b, shape tube 22 is held stationary.
Fig. 5 is the outside drawing of the details of the shape tube 22 of the brush retainer assembly 30 represented in execution mode of the present utility model.
As shown in Fig. 2 B and Fig. 5, in shape tube 22, be provided with at the 20sc place, side relative with the brush spring slits portion 20a that torsion brush spring 23 carries out sliding and cut shape tube 22 and the anti-flake 22a taking out and formed.Further, in the shape tube retainer portion 20 of end cap A 11, be provided with sheet slit 20c makes the anti-flake 22a of shape tube 22 from shape tube retainer portion 20 outstanding (with reference to Fig. 2 B).Be pressed into by shape tube 22 and anti-flake 22a bent after inserting, and making it chimeric with end cap A 11, shape tube 22 is fixed in end cap A 11 thus.Thus, prevent shape tube 22 from coming off.
In the brush retainer assembly 30 of the brush motor 10 formed as described above, the position keeping fixing by shape tube 22 is only the 20b of protuberance being everywhere arranged at shape tube retainer portion 20 inner peripheral surface.Thus, by the height of adjustment protuberance 20b, the press-in load between protuberance 20b and shape tube 22 can easily be adjusted.
In addition, four protuberance 20b are arranged at the position of the inner circumferential corner close to shape tube retainer portion 20, therefore, the shape tube 22 that steel plate bending is formed can with in the outside dimension of shape tube 22, rigidity by force and the most stable position be held stationary.Thus, stable press-in load can be guaranteed.
When each protuberance 20b is arranged on the position of inner circumferential corner of closely shape tube retainer portion 20, the abutted position of shape tube 22 falls R shape (fillet) part of the bending of steel plate, and therefore the size of shape tube 22 inside diameter becomes unstable.Thus, stable press-in load cannot be guaranteed.On the other hand, when each protuberance 20b is arranged at the position away from the inner circumferential corner of shape tube retainer portion 20, owing to being provided with brush spring slits portion 22c, anti-flake 22a, therefore easily produce the distortion to internal side diameter of shape tube 22 due to press-in load.Thus, be not only pressed into load and reduce, the slip of carbon brush 21 is also had an impact.
In addition, in order to prevent coming off of shape tube 22, in the side of shape tube 22, be provided with anti-flake 22a between two protuberance 20b up and down at a side.Thus, when the anti-flake 22a of shape tube 22 being bent after being pressed into by shape tube 22 and insert and make it be fitted together to end cap A 11, can by the space part be formed between protuberance 20b and shape tube 22 to absorb the micro-strain to shape tube retainer portion 20 side produced in shape tube 22.Therefore, it is possible to reduce the change in size of shape tube 22 inside diameter with doing one's utmost.Therefore, it is possible to guarantee the stable slip of carbon brush 21, thus the high brush retainer assembly 30 of reliability can be obtained.
Thus, brush retainer assembly 30 according to the present embodiment, can easily by the maintenance bed knife of shape tube retainer portion 20 pairs of shape tubes 22 of end cap A 11 adjustment also stabilisation.Therefore, it is possible to obtain the low and brush retainer assembly 30 that reliability is high of price.
In addition, can reduce with doing one's utmost produce when making anti-flake 22a bend, micro-strain is on the impact of shape tube 22 inside diameter.Thus, the stable slip of carbon brush 21 can be guaranteed.Thus, the brush retainer assembly 30 that reliability is high can be obtained.
Further, owing to there is not staking process for shape tube 22 being fixed on shape tube retainer portion 20, the operation such as fixing of other parts is utilized, therefore, it is possible to obtain the low and brush retainer assembly 30 that workability is high of price.
In the present embodiment, carry out the side surface part 20sa that slides and these about two faces of the side surface part 20sc relative with this side surface part 20sa at torsion brush spring 23 to be provided with shape tube 22 is kept fixing protuberance 20b, but, even if such four faces comprising the top and bottom had nothing to do with brush spring slits portion 20a all arrange protuberance 20b as shown in Figure 4 A, also there is same effect.
Brush retainer assembly of the present utility model and brush motor are suitable for make use of the brush motor of the end cap be made up of synthetic resin of shape tube, shape tube retainer portion and the end cap integration making to be formed by steel plate.Thus, to parts number of packages few, price is low and the home-use dust catcher of high reliability etc. are useful.
