Abstract

Disclosed in the utility model is a rotor core for a wind driven generator. At least 50 rotor punching sheets are fixed by bolts and nuts through bolt holes to form a rotor; at least two magnet slots and ventilation slots are arranged on the rotor; a permanent magnet is arranged inside each of the magnet slots; and the ventilation slots in fan shapes are uniformly arranged on the rotor punching sheets According to the utility model, the rotor core has advantages of large utilization rate of wind resources, high generating efficiency, fast thermal diffusivity and long service life.

Description

A kind of wind-driven generator rotor core
Technical field
The utility model discloses a kind of wind-driven generator rotor core altogether.
Background technology
In recent years, along with China's rapid economic development, supply of electric power is more and more nervous.Wind energy the most cheap, most promising this regenerative resource more and more is subject to people's attention, and it is a kind of " green energy resource " free from environmental pollution.At present, China very payes attention to wind power generation, and the wind-driven generator rotor is got over and become to being taken seriously as core component.The one end design fan structure of most of wind-driven generator rotor dispersing thermal recovery central shafts, so that the radiating effect of rotor is poor, useful life is short; If work for a long time in addition, cause easily rotor loosening, poor safety performance in the open air.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of generating efficiency high, and thermal diffusivity is fast, the wind-driven generator rotor core of long service life.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs:
A kind of wind-driven generator rotor core, described rotor fixedly is comprised of screw bolt and nut by bolt hole at least 50 rotor punchings, described rotor is provided with at least two magnet slot and ventilation slot, a permanent magnet is arranged in each magnet slot, described ventilation slot is fan-shaped, is evenly distributed on the rotor punching.
All be stained with anaerobic adhesive on the described screw bolt and nut.
The beneficial effect that the utlity model has: by the setting to rotor magnet groove permanent magnet, make its generating efficiency high; The design of rotor ventilation groove makes the rotor thermal diffusivity strengthen long service life; All be stained with anaerobic adhesive on the screw bolt and nut, rotor can be worked for a long time in the open air, should not become flexible.
Description of drawings
Fig. 1 is vertical view of the present utility model;
Fig. 2 is rotor punching schematic diagram of the present utility model;
Fig. 3 is left view of the present utility model.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
As shown in the figure, a kind of wind-driven generator rotor core, described rotor 1 fixedly is comprised of bolt 3 and nut 4 by bolt hole 2 at least 50 rotor punchings 11, described rotor 1 is provided with at least two magnet slot 5 and ventilation slot 6, a permanent magnet 7 is arranged in each magnet slot 5, and described ventilation slot 6 is fan-shaped, is evenly distributed on the rotor punching 11, make the rotor thermal diffusivity strengthen long service life.All be stained with anaerobic adhesive on described bolt 3 and the nut 4, rotor can be worked for a long time in the open air, should not become flexible.
During the utility model assembling, rotor punching 11 is added to behind the height that needs, at the uniform velocity put into and press-fit the rotor mould, after row is neat, aim at each through hole, bolt 3 and nut 4 are inserted in the bolt hole 2 the hand-tight make-up press mounting die, successively trivial tight bolt 3 and nut 4 after again queuing, like this rotor just assembling finished.The utility model induced potential is large, and power output is high, and the utilance of wind resource is large, improves generating efficiency, and thermal diffusivity is fast, has prolonged useful life.
