Reference numeral: 1, stator punching; 11, Access Division; 12, protuberance; 2, support ring; 3, banking stop; 4, retainer ring.
Embodiment
It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.Below with reference to the accompanying drawings and describe the present invention in detail in conjunction with the embodiments.
As depicted in figs. 1 and 2, the motor stator of the embodiment of the present invention comprises support ring 2 and along multiple stator punchings 1 of arranging of the stacked ground of the circumference of support ring 2, multiple stator punching 1 all perpendicular to the plane at support ring 2 place, multiple stator punching 1 and support ring 2 clamping.
Support ring 2 plays the effect of support stator punching, makes stator punching 1 form irradiation structure along stator inner ring circumferencial direction, and limits the movement of stator punching 1 in motor stator radial direction.Support ring 2 support stator punching 1, to strengthen the anti-pressure ability of stator, improves reliability when heavy load is run.
Motor stator comprises multiple support ring 2, and stator punching 1 comprises the multiple Access Divisions 11 suitable with multiple support ring 2.Multiple support ring 2 common support stator punching 1, improves the intensity of stator.The motor stator of the present embodiment comprises two support rings 2 being separately positioned on motor stator two ends, effectively improves stability and the intensity of motor stator.
Access Division 11 is for being opened in " L " shape draw-in groove on stator punching 1, and " L " draw-in groove comprises the Part I crossing with the edge of stator punching 1 and the Part II vertical with Part I.Multiple Part II of multiple Access Division 11 are positioned at the same side of the Part I of the Access Division 11 at itself place.Support ring 2 is arranged in the Part II of " L " shape draw-in groove, and motor stator also comprises the banking stop 3 of the corner being arranged on " L " shape draw-in groove.
The assembling process of motor stator is: 1, be fixed on by support ring 2 on a pedestal abreast; 2, the Part I of " L " draw-in groove be arranged on stator punching 1 is aimed at support ring 2, and stator punching 1 is moved to the position abutted with support ring 2; 3, move axially stator punching along motor stator, make support ring 2 be positioned at the Part II of " L " draw-in groove; 4, banking stop 3 is used to be clamped in the Part II of " L " draw-in groove by support ring 2.The designs simplification of the above motor stator assembling process of motor stator, improves productivity ratio, reduces production cost.Further, improve the intensity of motor stator.
Stator punching 1 also comprises the marking part be arranged on stator punching 1.Preferably, the sign groove that position is arranged on stator punching one end is indicated.Staff can judge the position of the Part II of " L " draw-in groove of stator punching 1 according to indicating the position of groove, thus avoids in the process of assembling, upside-down mounting stator punching 1 and cause the reduction of packaging efficiency.
Motor stator also comprise the two ends being separately positioned on multiple stator punching 1 and with two retainer rings 4 of multiple buffer substrate tablet clamping, multiple stator punching 1 include stator punching body and by stator punching body along motor stator axially to two protuberances 12 that the both sides of stator punching 1 extend, the protuberance 12 of multiple stator punching 1 forms annular boss, and two retainer rings 4 are set on the annular boss at the two ends of multiple stator punching 1 respectively.
The excircle of support ring 2 abuts with the Part II of " L " shape draw-in groove the effect playing support stator punching 1.Limit stator punching 1 along the radial direction of motor stator to the axe movement of motor stator.The inner periphery of retainer ring 4 on the annular boss that the protuberance 12 being set in multiple stator punching 1 is formed and annular boss abut against, and limit stator punching 1 along the radial direction of motor stator to the moving of direction in the axle center away from motor stator.Therefore, retainer ring 4 further increasing the intensity of motor stator.Meanwhile, the structure of motor stator is simple, and simple and convenient assembly, is conducive to the reduction of production cost.
