Abstract

The utility model relates to a main pole iron core structure of a direct current motor. The main pole iron core structure comprises a plurality of first main pole punching sheets and second main pole punching sheets, the first and second main pole punching sheets are connected in a mutual superposition mode to form a main pole iron core, open holes are arranged on the first and second main pole punching sheets, draw bars can be inserted into the open holes, and open holes on the second main pole punching sheets are provided with notches. The main pole iron core structure of the direct current motor has the advantages that the structure is simple, the installation is convenient, under the condition that the excellent magnetic performance characters of the motor are guaranteed, the open holes are arranged on the first and the second main pole punching sheets in advance, then the superposition is performed, and the installation is simple and convenient.

Description

A kind of main pole iron core structure of direct current machine
Technical field
The utility model relates to DC generator, especially a kind of main pole iron core structure of direct current machine.
Background technology
The structure of DC motor main pole iron core adopts the monoblock steel plate to process, and its advantage is that processing technology is simple and convenient, when iron core moves in non-uniform magnetic-field or is in time dependent magnetic field, can produce induced electromotive force, thereby forms eddy current loss.After change original monoblock steel plate structure into main pole punching superposition mode, but during this structure processing utmost point hole, need to hole in the main frame punching of the superimposed formula structure that is connected to form one, this kind method operating difficulties, especially for large-size machine, and for the main pole punching damage is arranged also, may cause loosening between each main frame punching of superimposed connection, affect subsequent installation and use.
The utility model content
The applicant provides the main pole iron core structure of another kind of direct current machine for above-mentioned shortcoming, has simply and easily advantage is installed, and effectively raises installation effectiveness.
The technical scheme that the utility model adopts is as follows:
A kind of main pole iron core structure of direct current machine comprises the first main pole punching and the second main pole punching of many mutual superimposed connections, forms main pole iron core; Having in the first main pole punching can be for the perforate of pull bar plug-in mounting, and having in the second main pole punching can be for the perforate of pull bar plug-in mounting, and the perforate of the second main pole punching is provided with breach.
Its further technical scheme is:
Perforate in described the first main pole punching and the second main pole punching is square opening.
The beneficial effects of the utility model are as follows:
The utility model is simple in structure, easy for installation, guaranteeing under the good condition of motor magnetic property characteristic, by in advance to perforate in the first main pole punching and the second main pole punching, then laminating, install simple and convenient, solve the problem that in the past need to be difficult in superimposed punching processing mounting holes, simplified installation steps and difficulty, greatly improved installation effectiveness.

Fig. 2 is the end view of Fig. 1.
Fig. 3 is for partly cuing open structural representation along Fig. 1 in the A-A direction.
Fig. 4 is the structural representation of the first main pole punching.
Fig. 5 is the structural representation of the second main pole punching.
Fig. 6 is the structural representation of pull bar.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.
As shown in Figure 1 to Figure 3, the utility model comprises the first main pole punching 1 and the second main pole punching 2 of many mutual superimposed connections, and the splicing line that formation main pole iron core 6(the first main pole punching and the second main pole punching are built up is not shown in the drawings); Such as Fig. 4, shown in Figure 5, have the first pull bar installing hole 1-2 and the first threaded mounting hole 1-1 in the first main pole punching 1, have the second pull bar installing hole 2-3 and the second threaded mounting hole 2-1 in the second main pole punching 2, the second pull bar installing hole 2-3 has breach 2-2.
Installation process of the present utility model is as follows:
As shown in Figure 1 and Figure 2, at first many first main pole punchings 1 are connected with the second main pole punching 2, the first pull bar installing hole 1-2 of (the first main pole punching is not shown in the drawings with the splicing line that the second main pole punching is built up) first main pole punching 1 and the second pull bar installing hole 2-3 of the second main pole punching 2 are corresponding, form main pole iron core.Then pull bar 3 is plugged in the first pull bar installing hole 1-2 and the second main pole installing hole 2-3, owing to have threaded mounting hole 3-1 on the pull bar 3, and the second pull bar installing hole 2-3 of the second main pole punching 2 is provided with breach 2-2, in breach 2-2 place, bolt 5 is installed on the pull bar 3, its installation is simple and convenient, saved in the past the loaded down with trivial details step that need to punch in the punching that laminates mutually, greatly improved installation effectiveness.At the both ends of the surface welding main pole end plate 4 of main pole iron core, main pole end plate 4 is finished installation in order to increase the first main pole punching 1 and the second main pole punching 2 superimposed rigidity that are connected with this at last.
The utility model is simple in structure, easy for installation, guaranteeing under the good condition of motor magnetic property characteristic, by in advance to perforate in the first main pole punching and the second main pole punching, and device is threaded the pull bar of installing hole in perforate, also have threaded mounting hole on the pull bar simultaneously, the convenient installation solved the problem that in the past is difficult to processing mounting holes in the punching laminated type, simplify installation steps and difficulty, greatly improved installation effectiveness.
More than describing is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range is referring to claim, and in the situation of basic structure of the present utility model, the utility model can be done any type of modification.
