At short vent segment (1) spot welding is fixed on above the round end flat key (4) of armature stamping (3) side, and long vent segment (2) is by circle
All spot welding is fixed on the surface of armature stamping (3), and keeps equidistant with armature stamping inside and outside circle, long vent segment (2) with it is short
Vent segment (1) is mounted on the same side, the ventilation channel plate that short vent segment (1), long vent segment (2), armature stamping (3) form
Device passes through round end flat key (4) again to carry out fastening with armature end flange (5) and couples, short vent segment (1), long vent segment (2), electricity
Pivot punching (3) is all made of impact style and is made, and wherein armature stamping (3) uses full circle punching mode.
Utility model works principle:
The function of the utility model is that axial ventilation structure used by solving conventional tank formula direct current generator can not be effective
Ground reduces the problem of heat generated after the heating conductors such as the coil of armature core surface insertion are powered.Structure is as shown in Figure 1, straight
The armature ventilation channel plate of galvanic electricity machine is mainly made of short vent segment, long vent segment and full circle armature stamping, short vent segment
Spot welding is fixed on above the round end flat key of armature stamping side, and long vent segment is scheduled on the table of armature stamping by circumferential point solid welding
Face, and keep equidistant with armature stamping inside and outside circle, long vent segment and short vent segment are mounted on the same side, short ventilation slot
Piece, long vent segment, armature stamping composition ventilation channel plate device pass through round end flat key again and carry out fastening with armature end flange and couple.
Short vent segment, long vent segment, armature stamping are all made of impact style and are made, and wherein armature stamping uses full circle punching
Mode.
The advantages of the utility model structure:
A kind of 1 novel radial ventilation device for armature core, is conducive to the cooling of armature core inner ventilation, significantly
Improve the heat-sinking capability of armature surface coil.
2 the utility model, which solve, lacks effective radial ventilation cooling device in previous armature core design, and
Mainly using axial ventilation hole as cooling air duct the problem of, the design feature of the present apparatus are that structure is relatively easy, the technique side of production
Formula is relatively simple, and the main body punching in device uses completely circular structure, excellent with the integraty after the assembly of armature core lamination.Cause
This, the utility model of the present apparatus had not only improved the effect of direct current generator inner armature ventilation, but also did not increased armature in manufacturing process
Complexity process implementing difficulty.In addition, the assembly using effect of utility model device is excellent by the realization of case study on implementation
It is good.
