Abstract
The utility model relates to the technical field of laminated core production and particularly discloses a novel structure of a sector iron chip for a laminated core, comprising the sector iron chip. A butt part used for being butted to an adjacent sector iron chip is respectively arranged on joint edges at both sides of the sector iron chip. The novel structure is characterized in that a locating and fastening slotted hole used for locating and fastening iron core lamination sheets which are laminated in a staggering way so as to form a circle layer is arranged at the outer margin of the sector iron chip and does not span the joint edges of the sector iron chip. The structure is beneficial to enhancing the locating effect between each layer of the iron core lamination sheets and an adjacent layer and reducing processing deformation of the iron core lamination sheets and has good use effect.
Description
Technical field
The utility model relates to electric rotating machine laminated core production technical field, particularly a kind of segmental core sheet new structure that is used for the electric rotating machine laminated core.
Background technology
Current, more and more for the use of motor.Correspondingly, also more and more higher for the requirement of stator core.At present, very most of electric rotating machine external stator core is spliced into ring back adjacent two layers (or which floor) seam portion by the identical shaped segmental core sheet of plurality of sections successively along circumference and is staggeredly stacked into individual components.Iron core is provided with the line embedding groove that is used to place the stator coil winding along inner edge portion, adjacent segmental core sheet junction was located on the inner periphery radial transmission line at line embedding groove middle part, the handing-over limit is provided with the tenon of splicing with the adjacent segment lamination, half cramp groove is respectively established in outer rim seam crossing both sides, piece together the back and become a cramp groove, iron core is shaped by V-arrangement cramp snap fastener film trap is fixing, and the iron core two ends that have also are provided with end clamp plate and iron-core workpiece welding.There is following shortcoming in this structure: 1, in the assembling process of laminated core, because the location between each layer of laminated core, fastening must the realization by the tightness that cooperates between cramp and cramp groove make its snap fastener film trap so need apply external force to cramp.Because cramp half groove is subjected to the extruding of cramp, the segmental core sheet is passed along the seam crossing both sides, thereby deforms, misplaces, and finally causes core lamination stack adjacent layer locating effect poor, and circularity is poor, and iron core cylindricity and lateral strength are poor.2, the cramp groove is located at the line embedding groove top center, causes iron core yoke portion to die-off at line embedding groove top center place area of section, and magnetic density increases, local pyrexia.
Summary of the invention
The purpose of this utility model is to provide a kind of segmental core sheet new structure, and this structure helps improving the core lamination stack adjacent layer and reaches the locating effect of each sheet of layer together, reduces the machining deformation of core lamination stack, and result of use is good.
The purpose of this utility model is achieved in that a kind of segmental core sheet new structure, comprise the segmental core sheet, be respectively equipped with on the described segmental core sheet both sides handing-over limit and be used for the docking section that connects with adjacent segmental core sheet, it is characterized in that: described segmental core sheet outer rim is provided with and is used for becoming the core lamination stack of ring layer to position and the fastening fastening slotted eye in location to intersecting, and the fastening slotted eye in described location is not crossed over the handing-over limit of segmental core sheet.
The beneficial effects of the utility model are to locate the position and the corresponding production technology of fastening slotted eye by changing segmental core sheet outer rim, reduce or avoided the generation of laminated core distortion in assembling process, dislocation even breakoff phenomenon, thereby improved production and processing precision, intensity, the electromagnetic performance of iron core.
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
