Three are radially arranged between reinforcement 11 in 120 ° of angles.
Fig. 4 and Fig. 5 are referred to, above-mentioned stretching motor case provided by the utility model is the part in motor case,
In assembling motor, as shown in Figure 4 and Figure 5, it is necessary to which two stretching motor cases for being open relative fasten each other, one is assembled into
The closing housing that rotor and stator are separated with external environment condition.Stator housing piece 3 and radiating in the stretching motor case of top
End cap 4 and the stator housing piece 2 in the stretching motor case of lower section and the structure for the end cap 1 that radiates are similar respectively.For the ease of two
Assembling between individual stretching motor case, the edge of another openend of the stator housing piece 2 is formed with radially outward
Raised flange 23, in assembling motor casing, the end face of the flange of upper and lower two stretching motor cases is coincided together,
Then the flange 23 of two stretching motor cases is fixed together using connector such as screw bolt and nut, you can to realize two
Being fastened between individual stretching motor case.
In order that the fastenings obtained between two stretching motor cases more fasten, the flange 23 and the stator housing piece
Formed with offering installation with the concentric toroidal cavity 25 of the flange 23, the bottom surface of the toroidal cavity 25 between 2
Hole 26, the toroidal cavity 25 of two stretching motor cases are engaged, the toroidal cavity 25 of one of stretching motor case
Outwardly relative to the flange 23 of the stretching motor case, the toroidal cavity of another stretching motor case is relative to the drawing
The flange for stretching motor case caves inward, so when assembling two stretching motor cases, outwardly toroidal cavity 25
It extend into the toroidal cavity to cave inward the toroidal cavity to cave inward with this to fit, it is possible thereby in the axial direction
Contact area between upper increase stretching motor case so that the cooperation of the two is even closer firmly.Outwardly annular
The bottom surface of groove 25 overlaps with the bottom surface of the toroidal cavity 25 to cave inward, and the mounting hole 26 on two bottom surfaces of groove 25 connects
It is logical, secured the two together by such as screw of the connector through the bottom surface upper installing hole 26.
The thickness for the stretching motor case that the present embodiment provides for example can arrive general 1mm-2mm with thin, and preferably 1.2mm is left
It is right.The inventor of present specification has found there is the motor of above-mentioned stretching motor case in actual use under study for action, may
It can be deformed at flange 23.
Refering to Fig. 6 and Fig. 7, in order to solve the technical problem of the deformation of flange 23, the outward flange position also shape of the flange 23
Into the flange flange 24 for having projection axially outward.Can also be on the end face of the flange 23 along the ring of the end face of flange 23
Circumferential direction sets flange reinforcing ribs 6.Thus, it is possible to improve the stress intensity of flange 23, suppress flange 23 and deform so that motor machine
The overall structure of shell is more firm.
In addition, the damping ring 20 as inner ring is typically integrally formed with outer ring, the generally use metal material system of damping ring 20
Into, compared with damping means made of rubber, silica gel elastomeric material, the effectiveness in vibration suppression phase of damping ring 20 made of metal material
To weaker.In order to preferably suppress bearing and stretch the vibration transmission between motor case, the inner side of damping ring 20 is provided with also
