Description
【Technical field】
Exciter technical field is the utility model is related to, more particularly to a kind of brushless exciter rotor field spider.
【Background technology】
Exciter rotor stent is a double-layer coaxial cylinder, and most stents are since its structure is not firm enough, intensity
It is relatively low, it is frequently present of in actual use or transport and deforms the problems such as being broken, particularly the moment of torsion of generator is big, vibrates greatly, pacifies
The deformation breakage problem of dress stent is particularly acute, and is made troubles to installing and using for client, or even causes discontented, gives motor manufacturer
Economic loss is caused, and original stent heat dissipation effect is poor.A kind of for this reason, it is proposed that brushless exciter rotor field spider.
【Utility model content】
The main purpose of the utility model is that a kind of brushless exciter rotor field spider is provided, it is outer by the way that inner cylinder is located at
Being partially installed on electric machine main shaft on the outside of cylinder, it is total to be arranged to outer cylinder by the length that inner cylinder is located inside outer cylinder
The half of length, can effectively improve the integral strength of stent, and the deformation of outer cylinder can be avoided using eight stiffener plates,
And the gap by being set between stiffener plate can strengthen air circulation, play good heat dissipation effect, can effectively solve
Certainly in background technology the problem of.
To achieve the above object, the technical solution that the utility model is taken is：
A kind of brushless exciter rotor field spider, including outer cylinder and inner cylinder, one end of the inner cylinder are located at outer cylinder
Inside, and inner cylinder is located at the half that length inside outer cylinder is outer cylinder total length, and the inner cylinder is positioned at outer
Stiffener plate is provided between one end of cylinder interior and outer cylinder, the shape of the stiffener plate is right-angled trapezium, described outer
The inner wall of cylinder is equipped with No.1 mounting groove, and the surface that the inner cylinder is located inside outer cylinder is equipped with No. two mounting grooves, described to add
The base of strengthening tendons plate is installed in No.1 mounting groove, and the top margin of the stiffener plate is installed in No. two mounting grooves.
Further, the No.1 mounting groove, No. two mounting grooves and stiffener plate are equipped with eight, and with cylinder
The heart is uniformly and symmetrically distributed, and the stiffener plate can be dismantled.
Compared with prior art, the utility model has the advantages that：By the way that inner cylinder is located on the outside of outer cylinder
Be partially installed on electric machine main shaft, the length that inner cylinder is located inside outer cylinder is arranged to the two of outer cylinder total length
/ mono-, the integral strength of stent can be effectively improved, the deformation of outer cylinder can be avoided using eight stiffener plates, and pass through
The gap set between stiffener plate can strengthen air circulation, play good heat dissipation effect.
