In addition, in the illustrated brush of side unit, the front of Fig. 36,, omitted brush carriage 18 and be contained in the diagram of the brush in the brush sleeve 19 in order to represent the structure and the configuration of brush sleeve 19 and conduction panel 20.
In core inductance body 17, formed terminal board 21,22.And, the first outstanding terminal 23 is installed respectively on two terminal boards 21, the second outstanding terminal 24 is installed on other two terminal boards 22.
In addition, in Fig. 3,25 expressions remain rotation bearing freely with the front side of rotating shaft 7.
Fig. 4 is in commutator motor shown in Figure 3 11, the stereogram of the state of omission rotor 13 and a related member and a side's (being the front side in the drawings) brush unit 6.According to Fig. 4, be appreciated that the relation of the brush carriage 18, brush sleeve 19 and the brush 26 that comprise in the brush unit 6.
One of feature of present embodiment is the structure of the front end face 26F of brush 26.Shown in the enlarged drawing of front end face 26F, be formed with a plurality of grooves 36 that extend along the direction of rotation A1 of rotor at front end face 26F, and alternately be formed with projection (prominent bar) 37 with groove 36, and the ora terminalis chamfering in the direction of rotation A1 downstream of rotor, and form scarf 35.About its structure, below be elaborated.
In addition, in Fig. 4, the stator winding that is wound in the stator core 15 via core inductance body 16,17 is reeled along the direction shown in the hollow arrow 31.Stator winding is wound on upper portion shown in hollow arrow 31, and also to be wound in the not shown following quadrate part with the rotor be center and the position of symmetry.
Fig. 5 is the three-face view that is used to illustrate the structure of brush 26, is the front view (front view of the front end face 26F of brush 26) of brush 26 (A), (B) is the vertical view of brush 26, (C) is the right side view of brush 26.
In the brush 26, the upper surface 26U except that its front end face 26F, lower surface 26D, left surface 26L, right flank 26R and back side 26B are implemented plating (for example copper facing), thereby can realize the raising of the electric conductivity of brush 26 integral body.In addition, the exit 27 of conductivity is outstanding from the rear end face 26B of brush 26.
One of pro forma feature of brush 26 is that the direction of rotation (direction of rotation of rotor 13) that front end face 26F is formed in commutator 12 goes up along the recessed flexure plane (with reference to Fig. 5 (B)) of the part of commutator segment 121 formed peripheries.That is, front end face 26F is for can seamlessly connecting airtight the shape that contacts (CONTACT WITH FRICTION) with the side face of commutator 12.In addition, be formed with a plurality of grooves (with reference to Fig. 5 (A), (C)) that the moving direction (direction of rotation of rotor 13) along commutator 12 extends abreast at the front end face 26F of this recessed bending.
And, the ora terminalis chamfering in the moving direction of commutator 12 among the front end face 26F (direction of rotation of rotor 13) downstream and form scarf (to call (C cutting face) in the following text) 35.
The partial enlarged drawing of Fig. 6 (B) presentation graphs 5 (B), the partial enlarged drawing of Fig. 6 (C) presentation graphs 5 (C).
In Fig. 6 (B), C cutting face 35 is formed on the ora terminalis in the downstream (target direction of the direction of rotation of the moving direction of commutator 12, rotor 13 and arrow A 1) of front end face 26F.As shown in the figure, C cutting face 35 for end edge portion from the front end face 26F side 26R inclination tangent plane that forms of chamfering obliquely to the right.Therefore, this C cutting face 35 is by along the direction cutting of leaving from the surface of commutator 12, becomes the cutting face of guaranteeing with the space length of commutator 12.
Therefore, though current concentration in the enforcement of brush 26 surface of plating (for example right flank) owing to can guarantee the space length of C cutting face 35 and commutator 12, therefore can suppress spark and produce by C cutting face 35.
Shown in Fig. 6 (C), be formed with a plurality of grooves 36 that the moving direction (direction of rotation of rotor 13) along rectifier 12 extends among the front end face 26F abreast.In other words, the front end face 26F of brush 26 form dell along with the continuous serrated face of direction of the direction of rotation quadrature of commutator 12.
Therefore, when the initial stage of rotation, the little protuberance of the front end face 26F of brush 26 contacts with commutator 12, pass through skimming wear, front end face 26F was worn down to along the shape of the side face shape of commutator 12 when protuberance was cut down, and became 12 whole state of contact of front end face 26F and commutator in the shorter time.
Promptly, after the commutator motor assembling, for the stabilisation of characteristic or quality testing and carry out test running, but between this break-in period, perhaps after the initial stage on-stream period between in, the front end face 26F of brush 26 and commutator 12 break-in are well eliminated the so-called not exclusively contact condition that the part of front end face 26F only contacts with commutator 12, thereby can be realized whole surface contact state in the running in early days.
In this case, if consider the contact condition of brush 26 and commutator segment 121, then the width W (with reference to Fig. 5 (A), (B)) of preferred brush 26 is with respect to the maximum size that contacts with four commutator segments of (rotation) commutator segment 121 (with reference to Fig. 3) that moves.And, in brush 26 with maximum width W that contacts with four commutator segments, because the downstream ora terminalis at its front end face 26F implements C cutting face 35, therefore consequently, front end face 26F become with respect to commutator segment 121 can not with the size that four commutator segments contact simultaneously, most of situation contacts with three commutator segments.
According to such structure, running first (during test running or between the initial stage on-stream period) at commutator motor, by forming C cutting face 35, skimming wear is carried out easily because the width (width of direction of rotation) of the front end face 26F of brush 26 is narrow, and front end face 26F forms whole contact with respect to commutator 12 at short notice.Thus, can realize the early stage input stabilisation of commutator motor.
In addition, after back tens hours, because skimming wear, the front end face 26F of brush 26 is cut down commutator motor gradually in the running beginning, and reduce in C cutting face 35, and brush width broadens.Thus, the current density that flows in brush 26 reduces, and can make rectified action more stable.At this moment, as long as make the width of brush 26 be pre-formed the width that contacts with four commutator segments 121 into maximum, just can form reduction that realizes current density and the structure that is difficult to cause vibration.
And then, in that having been implemented plating, the surface of removing front end face 26F and C cutting face 35 of brush 26 improves under the situation of energising performance, and current concentration is in the plating part.Therefore, in rectification direction (direction of rotation of commutator 12) rear end side, be easy to generate spark when separating with the front end face 26F of brush 26, especially in this embodiment on the surface of commutator 12, owing to implement cutting face 35 in this part, therefore have the possibility that is easy to generate spark.But in the present embodiment, because the cutting face is formed the C cutting face, therefore by this C cutting face 35, the front end of the plating that the right flank 26R surface of brush 26 is implemented separates in the mode of vacating space length from the surface of commutator 12.Therefore, can suppress the generation of spark.
And then, by forming C cutting face 35, can prevent electric current the concentrating of rectification direction downstream ora terminalis in the front end face 26F of brush 26, can prevent that the rectification direction ora terminalis side of brush front end face 26F is damaged.
And then, owing to be provided with a plurality of grooves 36 that extend along the direction of rotation of commutator 12 abreast at the front end face 26F of brush 26, therefore have front end face 26F and when test running, cut down easily, thereby can realize in early days and whole advantage that contacts of commutator face by the CONTACT WITH FRICTION wearing and tearing.
Next, with reference to Fig. 7～Figure 10, other features of the electric blower 1 of present embodiment are described.
Fig. 7 is the central longitudinal sectional view that electric blower shown in Figure 21 is cut open along central shaft.
The profile of electric blower 1 is made of the fan hub 5 of housing 2 that surrounds commutator motor 11 and covering air blast spring 4.And, in this electric blower 1, the housing 2 and the embedded structure of fan hub 5 have been implemented improvement.
That is, the leading section of housing 2 (being the left side in Fig. 7) has the flange 41 to foreign side's expansion, is formed with the ring 42 that turns back of further forward end direction bending at the circumference of flange 41.On the other hand, fan hub 5 has short shell body cylindraceous 43, and the rear end 44 of shell body 43 is pressed in the mode in ring 42 the outside of turning back of covering shell 2 and is embedded in the ring 42 that turns back, and thus, housing 2 combines with fan hub 5.
Fig. 8 (A) is the partial sectional view of flange 41, and Fig. 8 (B) is the local back view of flange 41.Present embodiment is characterised in that, shown in partial enlarged drawing among Fig. 8 (A), (B), be provided with the ring 42 that turns back in the outer peripheral edges of the flange 41 of housing 2 with the mode bending that forwards side (fan hub 5 sides) is outstanding, and this ring 42 that turns back is for annulus, is formed with at least one place of the ring 42 that turns back of this circle to the outstanding reinforcement of center position (axle side) with muscle 45.Be formed with on the flange 41 under the situation of steam vent 46, the preferred reinforcement is arranged on the position corresponding with the length direction central portion of this steam vent 46 (with reference to Fig. 8 (B)) with muscle 45.
During from rear side observation housing 2 integral body, as shown in Figure 9, encircle 42, be provided with at a place at least and strengthen with muscle 45 with respect to the turning back of outer peripheral edges of flange 41.
So, the ring 42 that turns back is provided with to be strengthened with muscle 45, with fan hub 5 be pressed into being embedded in the ring 42 that turns back after, shown in amplification view among Figure 10, the end edge of fan hub 5 with strengthen implementing fastening parts 47 with muscle 45 opposed parts.Consequently, when observing as a whole, be structure shown in Figure 7.
According to such structure,, therefore can prevent the distortion of flange 41 owing to strengthen with the flange 41 of 45 pairs of housings 2 of muscle by reinforcement.
And, by fastening part 47, can guarantee fan hub 5 with respect to housing 2 to axial anticreep intensity, and can realize that also fan hub 5 is to the rotation of direction of rotation restriction.
And then, strengthen being arranged on the position corresponding with steam vent 46 with muscle 45, also play the function of directing exhaust gas thus.
Next, with reference to Figure 11 and Figure 12, another feature of the electric blower 1 of present embodiment is described.
Figure 11 is the figure of expression stator winding 31 with respect to the reeling condition of the stator core 15 (also with reference to Fig. 4) of stator 14, and the state of stator 14 shown in Figure 4 is observed in expression from the right side.
In Figure 11, what the set of a plurality of roundlets was represented is stator winding 31, and stator winding 31 is wound in the stator core 15 via the core inductance body of installing with respect to stator core 15 16,17 (in Figure 11, the stator insulation body 17 of side in front of only having represented).In this case, the insulating trip 50 that configuration for example is made of polyester film in the groove 52 (volume has a side of stator winding 31) of the inboard that is formed at core inductance body 16,17 is across insulating trip 50 coiling stator winding 31 in groove 52.
In this case, insulating trip 50 forms film like, in order to avoid the winding space of stator winding 31 (space of groove 52) narrows down.Yet, add man-hour at the winding of stator winding 31, shown in dotted line among Figure 11 51, thereby exist insulating trip 50 to be pulled and in the coiling groove 52 of stator winding 31, stretch out the problem that the area (the coiling area of space of winding) that makes groove 52 narrows down.
At this, in the present embodiment, insulating trip 50 forms structure shown in Figure 12, forms the structure that the length direction central portion of insulating trip 50 can extend along the length direction of sheet.
That is, shown in Figure 12 (A), the insulating trip 50 that uses in the present embodiment is the width L rectangular rectangular shape bigger slightly than the width (thickness) of this stator core 15.And, alternately be formed with many crackles 53 from both sides at its length direction central portion.
Therefore, shown in Figure 12 (B), constitute following structure: insulating trip 50 when the length direction both end sides applies drag force, is extended in crackle 53 parts that the length direction central portion forms.
Thus, insulating trip 50 becomes the curved shape shown in Figure 12 (C), (D) and is installed in the groove up and down 52 of stator 14.And, under the state of installing, at last groove 52 or down in the groove 52, because the winding work of stator winding 31 is when applying drag force to the top of insulating trip 50 or bottom, the crackle 53 parts extension of the length direction central portion of insulating trip 50.Thus, can not float from the inner peripheral surface of groove 52 top or the bottom that are configured in the insulating trip 50 in the groove 52, and the area of the wrapping range of groove 52 is narrowed down.
Consequently, can effectively utilize groove area, realize that the conductor losses of commutator motor reduces, can realize high performance motor.
The present invention is not limited to the execution mode of above explanation, can carry out various changes in the scope of claims.
