Abstract
The utility model discloses a coil framework of a generator rotor. The coil framework comprises a coil framework body, wherein two ends of the coil framework body are provided with protruded limiting faces, and the limiting faces at two ends of the coil framework body are provided with paint dipping holes. A winding excircle of the coil framework body is provided with an anti-rotation rib. Insulating paint easily permeates into an innermost layer through the paint dipping holes on the coil framework and sticks the copper coil, limiting and fixing are performed through the anti-rotation rib on the winding excircle of the coil framework, so that the coil is firmly fixed on the coil framework and does not produce relative motion.
Description
Technical field
The utility model relates to technical field of generators, especially relates to a kind of coil rack of generator amature.
Background technology
The rotor of automobile current generator comprises coil rack and the coil on coil rack of being fastened.Wherein, coil rack is the insulating element of rotor.The rotor of the automobile current generator High Rotation Speed that is in operation, rotating speed is up to 21000rpm, acceleration-deceleration can reach 15000rpm/S, coil is fixing not tight at coil rack, coil meeting and coil rack relatively move, when displacement surpassed the elongation limit of copper cash, copper cash will be torn, and affects the normal operation of generator.
Mostly be at present fixing spacing to the coil on the coil rack by insulating varnish, but the insulating varnish on the coil rack is difficult for being penetrated into innermost layer, insulating varnish does not cling copper coil, and is fixing spacing poor.
The utility model content
Technical problem to be solved in the utility model provides a kind of coil rack of generator amature, to reach coil fixation on coil rack, the difficult purpose that relatively moves.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of coil rack of generator amature, comprise the coil rack body, described coil rack body two ends are provided with the confined planes of projection, and the confined planes at described coil rack body two ends is provided with the dipping lacquer hole.
The coiling cylindrical of described coil rack body is provided with anti-convulsion.
The center line of described anti-convulsion parallels with the axis of coil rack body.
The utility model compared with prior art, have the following advantages: by the dipping lacquer hole on the coil rack, insulating varnish is easy to infiltrate the innermost layer of coil, copper coil is clung, further, fix by the anti-convulsion on the coil rack coiling cylindrical, coil very firmly is fixed on the coil rack, the difficult phenomenon that relatively moves avoids the copper cash of coil to break.
Description of drawings
The below makes brief description to the expressed content of each width of cloth accompanying drawing of this specification and the mark among the figure:
Fig. 1 is the utility model coil rack organigram.
Fig. 2 is that schematic diagram is looked on the right side of Fig. 1.
Among the figure: 1. coil rack body, 2. dipping lacquer hole, 3. anti-convulsion.
Embodiment
The below contrasts accompanying drawing, by the description to embodiment, embodiment of the present utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of coil rack of generator amature comprises coil rack body 1, and coil rack body 1 two ends are provided with the confined planes of projection, carries out spacing to the coil that twines.
In order to realize goal of the invention of the present utility model, avoid the copper cash broken string of coil, the confined planes at coil rack body 1 two ends is provided with dipping lacquer hole 2.By the dipping lacquer hole 2 on the coil rack, insulating varnish is easy to infiltrate the innermost layer of coil, and copper coil is clung.The coiling cylindrical of the dipping lacquer hole off-line ring framework body on the confined planes is nearer, is convenient to the innermost layer that insulating varnish infiltrates coil fast.
Further, the coiling cylindrical at coil rack body 1 is provided with anti-convulsion 3.3 pairs of coils of anti-convulsion of projection carry out spacing.Preferably, the center line of anti-convulsion parallels with the axis of coil rack body.
By the dipping lacquer hole insulating varnish is infiltrated the innermost layer of coil, copper coil is clung, spacing by anti-convulsion anti-rotation again, coil is fixation on coil rack, and difficult relatively moving avoided the copper cash broken string of coil.
The above has carried out exemplary description to the utility model by reference to the accompanying drawings; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that design of the present utility model and technical scheme carry out; or without improving design of the present utility model and technical scheme are directly applied to other occasion, all within protection range of the present utility model.
Claims (3)
