Under the former situation, the inboard of peristome and the outside all become the processing under the tolerance of the strictness about maximum tens μ m, in order to utilize punch process front shroud are processed, and are needed exquisite punch process and man-hour to increase.And, in the latter case, if the thickness of slab of front shroud is constant; When then carrying out punch process for the dimensional tolerance that satisfies internal side diameter in theory, also should satisfy the dimensional tolerance of outer circumferential side, even but the plate of originally constant thickness of slab is carried out punch process; Owing to clamp the chimeric situation of (チ ヤ Star キ Application グ) or plus-pressure, punch die (ダ イ ス) etc.; And should take into full account, the situation that thickness of slab changes with tens μ m magnitudes, this also needs a lot of times or man-hour in processing.
Therefore, in the present invention, as shown in Figure 4; Utilize front shroud 17 to be peucinous characteristic; Utilize resin to carry out die forming and realize the homogenizing of machining accuracy, and, even if for the error that departs from claimed accuracy that also may produce like this; Interior all sides 84 at the peristome of front shroud are provided with a plurality of projections 81, make this projection 81 when assembling, plastic deformation take place and chimeric with the outer ring of the front side rolling bearing 33 that is installed on rotating shaft 32.
Thus, can not apply excessive external force, can guarantee that the concentricity of motor 100 and pump main body 95 is assembled rotating shaft 32.The size of this projection 81 is that the height h apart from inner peripheral surface 84 is about h=0.4 to 1.0mm.In addition; In the present embodiment; It is chimeric and utilize 33 ones on this front side rolling bearing that motor 100 is carried out the structures that single armed supports to form pump main body 95 and front side rolling bearing 33; Therefore because the eccentric force that the assembly error of 34 ones on front side rolling bearing 33 and rear side rolling bearing produces or the eccentric force of pump generation can absorb in pump main body 95 sides, can prevent that motor 100 from taking place because of these eccentric forces unusually.
Next, use Fig. 5, the embedding processing method to resinous front shroud 17 of conductivity ground plate 51 and positive plate 71 is described.Fig. 5 is the longitudinal sectional view of process of resin device.The mold 92 that the process of resin device will be formed with upper surface (right flank of Fig. 1 (a)) shape of front shroud 17 combines with the bed die 93 that is formed with lower surface (back side of the right flank among Fig. 1 (a)) shape of front shroud 17 airtightly.
In order ground plate 51 and positive plate 71 to be remained on the centre in the space 90 that is formed with this mold 92 and bed die 93, and as shown in Figure 3, be formed with a plurality of supported holes 73 at positive plate 71.Likewise, also be formed with a plurality of supported holes 53 at ground plate 51.On the position corresponding, be fixed in bed die 93, dispose stepped supporting pin 94 with these supported holes 53,73.Through will inserting the supported hole 73,53 of positive plate 71 and ground plate 51, and make ground plate 51 and positive plate 71 can not be in contact with one another, remain on to approximate horizontal in the space 90 of mold 92 and bed die 93 formation from the end of supporting pin 94 to end difference.At this moment, the end face 55 of ground plate 51 contacts with mold 92 or bed die 93.Next, through the formed resin material is injected from the inlet that is formed at mold 92 91, and the embedding of carrying out in resin is shaped.Thus, front shroud and electrode is integrally formed.
As previously discussed, according to present embodiment, front shroud is carried out ester moulding; And the front shroud behind this ester moulding is embedded in ground plate and positive plate; Therefore the machining period of front shroud reduces, and can reduce the weight of front shroud, thereby can realize the lightweight that requires when vehicle boarded.And, form projection and make this projection generation plastic deformation and carry out the centering (heart goes out レ) of front shroud at the central portion of front shroud, therefore can reduce the off-centre that the rotating shaft of motor or bearing etc. are applied and increase the weight of (increasing the weight of).And, according to present embodiment, in the processing of front shroud, can save punch process, can improve the machining accuracy of the installation portion of motor.
