Abstract
The utility model relates to a traction machine for an elevator and particularly relates to a stator for the traction machine. The stator comprises a core, wherein the core is formed by laminating multiple punching sheets, two ends of the core are respectively provided with an end board, the end boards are provided with end board grooves, periphery of each punching sheet is provided with at least two grooves, the grooves open outwards, periphery of the end boards is correspondingly provided with the end board grooves, the grooves and the end board grooves are linearly arranged along the laminating direction of the punching sheets, a metal rod penetrates through the grooves and the end board grooves, and the metal rod is respectively welded with the punching sheets and the end boards. The stator is reasonable and ingenious in structure design, saves production cost in small batch manufacturing for an enterprise, effectively improves production efficiency and fully and reasonably utilizes production resources; the punching sheets are welded with the two end boards through the metal rod, so the stator is more secure and is not liable to damage, the punching sheets are reasonably arranged and distributed, and the heat radiation effect of the tractor machine is excellent.
Description
Technical field
The utility model relates to the traction machine that a kind of elevator is used, and especially relates to the stator that a kind of traction machine is used.
Background technology
Existing traction machine comprises rotor, stator etc.Electric rotating machine with reference to Chinese patent, notification number is CN 102130558 A, the day for announcing is disclosed stator on July 20th, 2011: the stator with ring-type stator core, ring-type stator core forms with the stacked a plurality of laminations that are connected to each other by connecting portion of helical form, forms the groove extending along the stacked direction of stator core on the position that is provided with connecting portion of stator core outer peripheral face.
Iron core (stator) manufacture method being laminated by helical form with a plurality of interconnective punchings, can make the production cycle of stator and production cost greatly reduce.Yet this mode of production has but caused the negative effects such as means of production utilization is unreasonable, waste in the small lot batch manufacture of stator, has caused unnecessary the expending of the resources of production of enterprise, has increased the weight of enterprise's production cost, has reduced enterprises production efficiency.
Summary of the invention
The utility model object is just to provide a kind of stator that a small amount of is manufactured, firmly traction machine is used that is beneficial to.
The utility model object is achieved in that
The stator that a kind of traction machine is used, comprise iron core, described iron core is laminated by some punchings, and iron core two ends are respectively equipped with end plate, and end plate is provided with end plate grooves, every punching periphery is at least provided with two grooves, the outward opening of groove, end plate periphery also correspondence is provided with end plate grooves, and each groove is corresponding with end plate grooves to be arranged in a linear along the stacked direction of punching respectively, metal bar is located in groove and end plate grooves, and metal bar welds with punching, end plate respectively.
Technique scheme also can be made to the following further improve.
Described punching is provided with cooling ring.
Punching in the relative odd bits of punching on described even bit is along iron core axis direction rotation 90 degree, so that the corner of each piece punching forms heat radiation angle.
The utility model reasonable in design, ingenious, has saved the production cost of enterprise in small lot is manufactured, and effectively improves the production efficiency of stator, fully, reasonably uses the resources of production; And punching welds by metal bar and two end plates, make stator more firm, not fragile, punching distributes, arranges rationally, makes the radiating effect in traction machine good.

Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
Embodiment, as shown in Figures 1 to 6, the stator that a kind of traction machine is used, comprise iron core 1, described iron core 1 is laminated by some punchings 2, punching 2 is provided with cooling ring 3, in the both ends of the surface of iron core 1, be respectively equipped with end plate 4, end plate 4 is provided with end plate grooves 5, every punching 2 peripheries are provided with eight grooves 6, the outward opening of groove 6, and each groove 6 is arranged in a linear along the stacked direction of punching 2 respectively with end plate grooves 5, metal bar 7 is located in end plate grooves 5 and groove 6, and punching 2, end plate 4 weld with metal bar 7 respectively.
Described end plate 4 is provided with end plate aperture 41, in every punching 2, be also provided with punching hole 21, punching hole 21 is with end plate aperture 41 respectively along iron core 1 axis direction linear array, and spill (not shown) is set in punching hole 21 and end plate aperture 41, end plate 4 and spill welding.
As shown in Figure 4 and Figure 5, described iron core 1 is laminated by 9 punchings 2 that are provided with cooling ring 3, punching 2 in the relative odd bits of punching 2 on even bit is along iron core 1 axis direction 90-degree rotation, so that the corner of each piece punching forms heat radiation angle 8, punching 2 on even bit is connected with the punching 2 in odd bits, because the arrangement of every punching 2 is reasonable, the heat radiation angle 8 that the punching 2 in even bit and odd bits highlights outside has good heat sinking function, thereby makes iron core 1 heat radiation better.
