Description
Technical field
The utility model belongs to technical field of motors, especially for the pole core structure of large-scale steel mill electric machine.
Background technology
In known technology, the pole core of large-scale steel mill electric machine is at the pole core thread mill drilling, and on screwed hole, the magnetic pole screw rod is installed, and by the magnetic pole screw rod, pole core is arranged on rotor field spider.Traditional way is direct thread mill drilling thereon after pole core dress is pressed, and have following defective: (1) directly processes pole lamination, and rotten tooth easily appears in processing difficulties; (2) leave burr between pole lamination after processing, make it have the gap, cause intensity to descend.
The utility model content
The purpose of this utility model is not enough for prior art, provides a kind of easy to process, the reliable motor pole core construction of intensity.
realize that the technical scheme that the purpose of this utility model is taked is: this pole core structure comprises retaining ring, pole end-plate, the first pole lamination, the second pole lamination, the 3rd pole lamination, the magnetic pole pin rod, the magnetic pole screw rod, magnetic pole iron and hush panel, wherein the 3rd pole lamination is provided with breach, the magnetic pole pin rod is provided with screwed hole, each pole lamination laminates by magnetic pole pin rod and magnetic pole iron and is contained in the middle of pole end-plate, the 3rd pole lamination is corresponding with the screwed hole of magnetic pole pin rod, described pole end-plate and retaining ring are welded to connect, and be connected with pole end-plate, the magnetic pole iron passes pole lamination and pole end-plate is welded to connect, the magnetic pole pin rod passes after pole lamination the gap by hush panel shutoff magnetic pole pin rod and pole end-plate, pole end-plate, the magnetic pole pin rod is connected connection with hush panel.
Described the first pole lamination adopts silicon steel sheet 50W470 product.
The gap portions of described the 3rd pole lamination is provided with the magnetic pole screw rod, and this magnetic pole screw rod is arranged on the screwed hole of magnetic pole pin rod.
According to the steel mill electric machine pole core structure that such scheme is made, its beneficial effect:
