It is placed in grooved ring.
Described bulge loop and groove shapes match, and cross section is rectangle, triangle or semicircle.Owing to external member 2 is
Bulge loop structure, during swollen thin-wall sleeve, the shape of annular groove is affected by the formation of bulge loop, then the form phase of the annular groove shape formed and bulge loop
Seemingly, same, owing to thin-wall sleeve 1 exists tension force, for rectangle and triangle, seamed edge has certain radian and non-critical
Linear structure.As shown in Figure 4, it is shown that the cross section of bulge loop is semicircular assembling structure.
Connecting fixing reliability to improve, described annular groove is identical with the quantity of bulge loop, the most at least two.
The method preparing the package assembly of motor external member and thin-wall sleeve, including step be:
A, prepare connecting portion there is the external member 2 of ring muscle 21；
B, thin-wall sleeve 1 insert external member 2；
C, it is built into elastic expansion body 5 at thin-wall sleeve 1；
D, elastic expansion body 5 being applied pressure, make to be formed on thin-wall sleeve 1 ring muscle 11, the thin-wall sleeve extent of rebound of ring muscle position is minimum,
I.e. ring muscle constraint thin-wall sleeve resilience, makes thin-wall sleeve keep expansion state in ring muscle position, makes the ring muscle on described thin-wall sleeve and institute
The ring muscle stating external member is nested；
E, withdraw elastic expansion body 5.
As it is shown in figure 5, place elastic expansion body 5 in thin-wall sleeve 1, as shown in Figure 6, elastic expansion body 5 both sides are applied axially
Extruding force, carries out radially distending, makes thin-wall sleeve diameter swell and be adjacent to external member inwall, along with axial compression power continues thin-wall sleeve 1
