Abstract
The utility model relates to a motor, comprising a stator provided with a silicon steel sheet group, a winding and a hollow cylindrical insulation sleeve used for spacing the silicon steel sheet group and the winding, and a stator base provided with a hollow cylindrical hub part. The hub part is composed of first upright ribs and second upright ribs which are arranged in a stagger mode along the circumferential direction. The silicon steel sheet group of the stator sheathed with the hub part is clamped and positioned along the axial direction by an outer buckling part of the first upright ribs and an outer staircase part of the second upright ribs. A non-cylindrical surface at the outer circumference of the hub part is matched with a non-cylindrical surface at the inner circumference of the stator, which leads the stator to be clamped and positioned along the circumferential direction.
Description
The utility model relates to a kind of motor apparatus.
Fig. 1 is a part exploded perspective view of commonly using d.c. motor.This motor comprises: a rotor (not shown), a bearing 60, an armature assembly B (being constituted by a stator 70 and a circuit board 80), and certain subbase seat 90.This rotor has a rotating shaft (not shown).Bearing 60 has a centre bore 61, in order to holding the rotating shaft of this rotor, and supports freely rotating of this rotor.
With reference to figure 1 and 6, stator 70 has: the silicon steel sheet group 71 that is built up by most silicon steel sheets; Coiling (with reference to the part that is denoted as W among the figure 7B) is in order to produce the required magnetic field of motor; The insulating case 72 of hollow cylindrical is separated this silicon steel sheet group 71 to reach the insulation purpose with this coiling; And most angles 73.
Fig. 6,7A, 7B show the assembling mode of armature assembly B shown in Figure 1.Wherein, Fig. 6 is a cutaway drawing.And Fig. 7 A is the partial enlarged drawing of it " Y " of Fig. 6 part.Near the cutaway view of Fig. 7 B for giving turned upside down and further be amplified the part shown in Fig. 7 A.Shown in Fig. 7 B, stator 70 withstands the medium pore 81 edge portions of circuit board 80 with end 72L under its insulating case 72, and utilize an alignment pin P to pass circuit board 80 and insert in the angle 73, withstand circuit board 80 with angle 73 again, coiling W is installed between insulating case 72 and angle 73, and the end of coiling W is wound on the alignment pin P.Under state shown in Fig. 7 B, stator 70 was imposed the operation of tin stove in the lump together with circuit board 80, and made scolding tin be attached to the joining place of alignment pin P and circuit board 80, and circuit board 80 and stator 70 are combined into armature assembly B.
The shortcoming of the assembling mode of aforementioned armature assembly B is: when implementing the operation of tin stove, if crack heterogeneity or vibrate between holding between 72L under circuit board 80 and the insulating case 72, then can cause locating bias, cause in the armature assembly B that combination is finished, bad situations such as warpage, deflection can take place in circuit board 80.
As shown in Figures 1 to 4, stator base 90 has: a pedestal part N, in order to containment circuit board 80; And the M of hub portion that becomes hollow tube-shape substantially, be integral and be connected with the central authorities that stand on the N of this.The M of hub portion comprises: one becomes top 91 cylindraceous substantially; One becomes cylindric bottom 92 substantially, and is slightly larger than top 91; And be connected in end difference 93 between the two.The silicon steel sheet group 71 of stator 70 is set in the periphery on top 91, and is supported in the bottom surface (Fig. 3) of silicon steel sheet group 71 by end difference 93.The periphery on top 91 is fixed in silicon steel sheet group 71 with viscose in 91 outer peripheral face 94 and coating on top.In the center of the M of hub portion and offer the centre bore 95 of a setting-in radial journal bearing 60 usefulness.Fig. 4 shows that bearing 60 is flush-mounted in the situation in the centre bore 95.
The structure of stator former pedestal 90 has following shortcoming.At first, because silicon steel sheet group 71 is to be bonding on week outside the top 91 of the M of hub portion with viscose, viscose not only is subjected to high temperature and is easy to go bad, and apply viscose at every turn and can't guarantee that its consumption is suitable, can't guarantee that stator 70 is enough with the bond strength of stator base 90, be difficult to definitely prevent stator 70 with respect to stator base 90 axially with circumferential displacement, trustworthiness is not good.Be not provided with engaging detent mechanism again in the centre bore 95 because of stator base 90 for bearing 60, must be by forcing fit system that bearing 60 setting-ins are limited to the interior location of centre bore 95.If cooperate too tightly, in then the rotating shaft of rotor after this is difficult to pack into the centre bore 61 of bearing 60, cooperated pine bearing 60 can't be limited to the location really again, the border that coordinating operation is faced a difficult selection.
In view of aforementioned many disadvantages of commonly using motor configuration, the purpose of this utility model provides a kind of motor apparatus, must be by means of the gummed mode, can prevent really stator with respect to stator base axially with circumferential displacement, and significantly improve the acceptance rate and the trustworthiness of product.
Another purpose of the utility model provides a kind of motor apparatus, must bearing can be limited in the centre bore of stator base by means of forcing fit system, and increase substantially the acceptance rate and the trustworthiness of product.
