In certain embodiments, as shown in figures 3 to 6, fixed core assembly 211 comprises: stiff shaft 2111 and resilient sleeve 2112, wherein, stiff shaft 2111 is axle core, be enclosed within outside resilient sleeve 2112 on stiff shaft 2111, and be enclosed within resilient sleeve 2112 outside housing stator assemblies 304, form the positioning form of overcoat successively.
Wherein, only be against on the F5 of diameter of stator bore face when resilient sleeve 2112 is radially opened, can ensure that the central shaft of diameter of stator bore face F5 and stiff shaft 2111 is to overlapping, like this, when location afterwards, navigation system 210, positions the first frame 111, second frame 121 for positioning datum with diameter of stator bore face F5.That is, a set of expansion core clamping device that the location of housing stator assemblies 304 and clamping are is benchmark with diameter of stator bore face F5.
Particularly, as shown in figures 3 to 6, the outer peripheral face of stiff shaft 2111 be male cone (strobilus masculinus) Z1 at least partially, be enclosed within stiff shaft 2111 outside resilient sleeve 2112, stiff shaft 2111 can move up and down relative to resilient sleeve 2112, the inner conical surface Z2 being formed as matching with male cone (strobilus masculinus) Z1 at least partially of the internal perisporium of resilient sleeve 2112, resilient sleeve 2112 to be configured to when stiff shaft 2111 moves towards one end that the cross-sectional area of inner conical surface Z2 reduces resilient sleeve 2112 radially elasticity open, resilient sleeve 2112 is only against on the F5 of diameter of stator bore face when radially elasticity is opened.Thus, fixed core assembly 211 structure is simple, processing ease, and can realize good location, the clamping of housing stator assemblies 304.
Wherein, the male cone (strobilus masculinus) Z1 of stiff shaft 2111 is substantially identical with the tapering of the inner conical surface Z2 of resilient sleeve 2112, thus ensures that the male cone (strobilus masculinus) Z1 of resilient sleeve 2112 is close on the inner conical surface Z2 of resilient sleeve 2112 at least partially.Here, when moving towards one end that the cross-sectional area of the inner conical surface Z2 of resilient sleeve 2112 reduces at stiff shaft 2111, stiff shaft 2111 compresses axially resilient sleeve 2112, and resilient sleeve 2112 elastic deformation occurs and opens to radial direction.Therefore resilient sleeve 2112 and stiff shaft 2111 snug fit, resilient sleeve 2112 can be out of shape immediately when stiff shaft 2111 moves axially, thus improve the sensitivity of control.In the example shown in Fig. 3 and Fig. 6, the outer peripheral face of resilient sleeve 2112 is the face of cylinder, and inner conical surface Z2 and external cylindrical surface are coaxially arranged.Alternatively, resilient sleeve 2112 is spring steel.
More specifically, one end of stiff shaft 2111 connects driver (scheming not shown), stiff shaft 2111 is pulled to move during drive operation downwards, the male cone (strobilus masculinus) Z1 of stiff shaft 2111 contacts with the inner conical surface Z2 of resilient sleeve 2112, promote resilient sleeve 2112 radial direction to open, the external cylindrical surface of resilient sleeve 2112 contacts with diameter of stator bore face F5, with clamping body stator assemblies 304.
Advantageously, upper positioning seat 212 or lower positioning seat 214 are provided with axis hole 217, and stiff shaft 2111 extend in middle shell 3 through axis hole 217.Axis hole 217 can limit stiff shaft 2111 moving axially along axis hole 217 with coordinating of stiff shaft 2111, improves the control accuracy of stiff shaft 2111.Wherein, the orientation assemble face on the central axis of axis hole 217 and corresponding upper positioning seat 212 or lower positioning seat 214 is perpendicular.
In certain embodiments, as shown in Figure 1-Figure 3, auxiliary bearing 122 matches with bent axle 6 through after the second frame 121, and the upper surface of the second frame 121 is orientation assemble faces of location auxiliary bearing 122.Because base bearing 7, supplementary bearing 9 or cylinder 8 in compression assembly C are fixedly connected in the first frame 111, in the example of fig. 1, the lower surface F2 of the first frame 111 is the orientation assemble face of compression assembly C.
Like this, for bent axle 6 after ensureing to install is arranged with auxiliary bearing 122 is concentric, will ensure during installation that the first frame 111 parallels with the second frame 121, in the example of especially Fig. 1, the lower surface F2 of the first frame 111 is parallel with the upper surface of the second frame 121.
When assembling, also to ensure the first frame 111 and the second frame 121 aperture surface F5 perpendicular to stator 4 simultaneously, namely in the example of fig. 1, the lower surface F2 of the first frame 111 and the central axis of stator 4 perpendicular, the upper surface of the second frame 121 and the central axis of stator 4 perpendicular.Specifically, when mounted, first frame 111 and the second frame 121 all with the aperture surface F5 of stator 4 for locating surface, ensure that the corresponding orientation assemble face of the first frame 111 and the second frame 121 is all perpendicular with the central axis of stator 4, like this, also just can ensure to install rear rotor 5 and stator 4 better can coaxial cooperation, ensures gap uniformity between rotor 5 and stator 4.
Particularly, compression assembly C by with the diameter of stator bore face S5 of electric machine assembly B feel relieved install after be connected in the first frame 111, the central axis of the central axis of compression assembly C and stator 4 can be made like this to be located along the same line, and namely bent axle 6 coaxially can be arranged with stator 4.When bent axle 6 coordinates with auxiliary bearing 122, auxiliary bearing 122 is wanted first to be connected in the second frame 121 after aligning again, like this, can ensure that the central axis of auxiliary bearing 122 and the central axis of bent axle 6 are located along the same line.After said method assembling, can make coaxially to arrange between rotor 5 and stator 4, ensure gap uniformity between stator 4 and rotor 5.
In certain embodiments, as shown in Figure 6, resilient sleeve 2112 is provided with and hollows out groove k, that is, resilient sleeve 2112 cuts out a part on perisporium, like this, resilient sleeve 2112 is more prone to radial direction and opens after being squeezed, and improves the control sensitivity of fixed core assembly 211 further.
Particularly, hollow out the groove k outer peripheral face of through resilient sleeve 2112 and inner peripheral surface diametrically, like this, resilient sleeve 2112 radial direction is opened and is more prone to.
More specifically, as shown in Figure 6, hollow out groove k and at least comprise the multiple first pilot trench k1 and multiple second pilot trench k2 that are arranged alternately, first pilot trench k1 and the second pilot trench k2 extends respectively vertically, multiple first pilot trench k1 is through towards the upper surface of resilient sleeve 2112, and multiple second pilot trench k2 is through towards the lower surface of resilient sleeve 2112.Thus, improve further resilient sleeve 2112 be squeezed after radial deformability.
In some concrete examples, as shown in Figure 6, what resilient sleeve 2112 is provided with more than 6 staggered hollows out groove k, non-through one end of each first pilot trench k1 and the second pilot trench k2 is provided with bottom outlet k3, the diameter of bottom outlet k3 is greater than the groove width hollowing out groove k accordingly, and advantageously, bottom outlet k3 is circular port.
In certain embodiments, the end face of resilient sleeve 2112 is only against in the first frame 111 or the second frame 121 after tool locating completes, advantageously, the end face contacted with corresponding frame of resilient sleeve 2112 and the central axis of inner conical surface Z2 perpendicular, that is, resilient sleeve 2112 also achieves the function of clamping frame while location.
