Any one extension fixture can also be resetted using structure as shown in figure 21 in addition to being resetted using elastomeric element,
Which is：203 other end of body of cutting somebody's hair is provided with cavity 203a, and the expanding plate is provided with gib head 210, the gib head 210
Groove is formed between expanding plate, the body 203 of cutting somebody's hair is embedded in the groove, and gib head 210 is inserted into and cuts somebody's hair this
In cavity on body.The advantage of this mode is, when cut somebody's hair 203 axial displacement of body when, outside body 203 of cutting somebody's hair
The effect that the inclined-plane of taper seat and expanding plate is supported, makes expanding plate form the displacement of radial direction, but 203 axial displacement mistake of body of cutting somebody's hair
Cheng Zhong, what the inner surface of body 203 of cutting somebody's hair was supported with gib head 210 all the time.When cut somebody's hair 203 return of body when, due to body of cutting somebody's hair
203 inner surface and the mutual counter-active effect of gib head 210, body 203 of cutting somebody's hair drive gib head 210 along the radial contraction of core rod 202,
Drive expanding plate radially contracted, so that expanding plate resets.Moreover, due to such gib head 210 and body 203 of cutting somebody's hair
Cooperation, in the case of 202 internal diameter identical of core rod, the external diameter of the body of cutting somebody's hair of this mode, shown in Figure 15 section
Pushing away an external diameter cut somebody's hair can be bigger, so, expanding plate can be made to obtain the displacement of bigger radial direction, and the shaping to coil has
Preferably effect, i.e., by this frame mode, after rotor is assembled in the stator, have bigger climbing between stator and rotor
Electrical distance.
In addition, as a kind of mode of texturing of the body 203 of cutting somebody's hair shown in Figure 21, as shown in figure 22, the body of cutting somebody's hair
203 include that taper surface is cut somebody's hair 203b, and cut somebody's hair one end of 203b of the taper surface is provided with multiple extensions being arranged on same circumference
203c, forms resigning groove 203d between two neighboring extension, the outer surface of extension is the conical surface.This structural representation is pushed away
Head body, it is also possible to use cooperatively with gib head 210 as shown in Figure 21, but, due to the presence of groove 203d, in actual work
During, the iron yoke between two adjacent line embedding grooves that can be allowed in stator core enters into 203d in the groove, to keep away
Exempt from iron yoke and interference is produced with body of cutting somebody's hair, therefore, it can further lift the displacement of expansion.
