Abstract
The utility model discloses a single bearing brushless synchronous electric generator without a front end cover, which belongs to the electric generating device in mechanical and electrical products. The utility model is characterized in that a main electric generator stator is fixedly connected with a base, a main electric generator rotor is matched in the middle of the main electric generator stator, the back end of the main electric generator rotor is provided with an exciter stator, and an exciter rotor is matched in the middle of the exciter stator which is fixed on a back end cover and a bearing, wherein the installation size of the base is the same as the installation size of a diesel engine bell housing. Because the front end cover is removed, vanes of a fan are arranged between a stator front end winding end part and the base, consequently the user requirement is met, the length of the single bearing brushless synchronous electric generator is shortened and the weight of the brushless synchronous electric generator is reduced. At the same time, the utility model is simple in structure and stable and reliable to use and is a new upgrade variety of the modern common single bearing brushless synchronous electric generator.
Description
Technical field
The utility model relates to the generating equipment in the electronic product, and a kind of specifically single shaft that does not have front end housing holds no-brush synchronous generator.
Technical background
As everyone knows, common single shaft hold no-brush synchronous generator usually by front end housing, the band support main generator unit stator, main generator rotor, exciter stator, exciter rotor, rear end cap and bearing form.The standing part that common single shaft holds no-brush synchronous generator is connected with the support of generator by bolt by an end seam of front end housing, other end seam is connected with the bell housing of diesel engine by bolt, front end housing is the excessive parts that connect diesel engine and generator, its rotating part is connected with the flywheel of diesel engine by the driving chip on the main generator rotor, and the fan of generator is placed in the front end housing.Common single shaft holds no-brush synchronous generator because front end housing is arranged, and causes the generator Structure complexity, and parts are many.The generator axial length of this kind structure is long simultaneously, volume is big, Heavy Weight.For this reason, overcome its shortcoming and become the task of top priority.
The utility model content
In order to overcome the deficiencies in the prior art, it is little, in light weight, simple and reasonable for structure that the purpose of this utility model provides a kind of volume, can satisfy a kind of single shaft that does not have front end housing that the user must ask and hold no-brush synchronous generator.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of single shaft of the no front end housing formed of main generator unit stator, main generator rotor, exciter stator, exciter rotor, rear end cap and bearing by the band support holds no-brush synchronous generator, it is characterized in that: main generator unit stator is fixedlyed connected with support, be combined with main generator rotor in the middle of the main generator unit stator, the main generator rotor rear end is provided with exciter stator, be combined with exciter rotor in the middle of the exciter stator, exciter stator is to be fixed on rear end cap and the bearing; Wherein, the installation dimension of support is identical with the installation dimension of diesel engine bell housing.
Described fan is by forward flange, and blade and rear flange are formed, and fan is whole to adopt the die casting aluminium shaping to form; Blade is radially long narrow shape structure; Fan is installed in main generator rotor, fan the time sheet the position be to be placed between the end of support and main generator unit stator.
The installation dimension of the utility model support front end seam is consistent with diesel engine bell housing installation dimension, and fan adopts the radially long narrow shape blade of die casting aluminium, and the blade of fan is placed between stator front end winding overhang and the support.The support of generator directly links to each other with the bell housing of diesel engine.It is identical that its operating state and common single shaft hold no-brush synchronous generator.
The beneficial effects of the utility model are: because the utility model cancellation front end housing, the blade of fan is placed between stator front end winding overhang and the support, thereby can reach customer requirements: shorten single shaft and hold the length of no-brush synchronous generator, and alleviated the weight of no-brush synchronous generator.Simultaneously, the utility model structure is not only simple, and uses reliable and stablely, is the new varieties of the update of modern common single shaft no-brush synchronous generator.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is an assembly structure schematic diagram of the present utility model.
In the drawings, 1 driving chip, 2 supports, 3 fans, 4 main generator unit stators, 5 main generator rotors, 6 exciter stators, 7 exciter rotors, 8 rear end caps, 9 bearings.

3-1 forward flange among the figure, 3-2 blade, 2-3 rear flange.
Embodiment
Embodiment 1:
See also Fig. 1, the single shaft of the no front end housing of present embodiment holds the support 2 of no-brush synchronous generator by main generator unit stator 4, with the main generator rotor 5 in the middle of the main generator unit stator, exciter stator 6, with the exciter rotor 7 in the middle of the exciter stator 6, and the rear end cap 8 of fixed excitation machine stator 6 and bearing 9 compositions.The installation dimension of the support 2 of present embodiment is by the installation dimension decision of diesel engine bell housing.
Fig. 2 and shown in Figure 3, fan 3 is made up of forward flange 3-1 blade 3-2 and rear flange 3-3, fan 3 whole employing die casting aluminiums are shaped and form, blade 3-2 is radially long narrow shape structure, fan 3 is contained on the main generator rotor 5, and the position of the blade 3-2 of fan 3 is to be placed between the end of support 2 and main generator unit stator 4.
