Abstract
The utility model relates to a coil, in particular to an eddy retarder coil. The eddy retarder coil comprises a coil skeleton, a frustum-shaped coil and a protection shell, wherein the frustum-shaped coil of which the upper part is wide and the lower part is narrow is fixedly arranged in the coil skeleton; the outer side of the frustum-shaped coil is fixedly provided with the protection shell. The eddy retarder coil is simple in structure and convenient in use. A taper design is adopted through the coil, therefore, the stator space is effectively utilized, the coiling space is increased, and the work efficiency is increased.
Description
Technical field
The utility model relates to a kind of coil, is a kind of eddy current retarder coil.
Background technology
Current vortex retarder is a kind of auxiliary brake device for automobile, is commonly called as electricity and stops and be made up of stator, rotor and fixed support as the one of which.The kinetic energy of vehicle ' just finally is converted into heat energy through electromagnetic induction and resistance heating and distributes during work.But for less installation site, space, the installing space of coil also diminishes, so there are not enough winding volumes to twine electromagnetic wire, wastes time and energy inefficiency when mounted.
Summary of the invention
The utility model provides a kind of eddy current retarder coil, has overcome the deficiency of above-mentioned prior art, and it can solve less installation site, space and cause not having enough winding volumes to twine the problem of electromagnetic wire.
The technical scheme of the utility model realizes like this: a kind of eddy current retarder coil; Comprise coil rack, taper type coil and protection housing; At the coil rack internal fixation taper type coil wide at the top and narrow at the bottom is installed, is fixed with the protection housing in the taper type coil outside.
Above coil rack comprises upper frame, coiling ring body and lower frame; Be fixed with the coiling ring body between upper frame and the lower frame; There is the installing hole that communicates at the middle part of upper frame, coiling ring body and lower frame, and the external side of wire winding ring is installed with taper type coil wide at the top and narrow at the bottom, and the external diameter of upper frame is greater than the external diameter of lower frame; The external diameter of coiling ring body is less than the external diameter of lower frame, and the external diameter of upper frame is corresponding with the top and the bottom external diameter of taper type coil respectively with the external diameter of lower frame.
The outside of above upper frame and lower frame is cambered surface.
The utility model is simple in structure, and is easy to use, adopts taper design through coil, effectively utilized stator space, increased winding space, improved operating efficiency.
Description of drawings
Fig. 1 looks sectional structure chart for the master of the utility model.
Coding among the figure is respectively: 1 is the taper type coil, and 2 are the protection housing, and 3 is upper frame, and 4 are the coiling ring body, and 5 is lower frame, and 6 is installing hole.
Embodiment
As shown in Figure 1, a kind of eddy current retarder coil comprises coil rack, taper type coil 1 and protection housing 2, at the coil rack internal fixation taper type coil 1 wide at the top and narrow at the bottom is installed, and is fixed with protection housing 2 in taper type coil 1 outside.
As shown in Figure 1; Coil rack comprises upper frame 3, coiling ring body 4 and lower frame 5; Be fixed with coiling ring body 4 between upper frame 3 and the lower frame 5; There is the installing hole 6 that communicates at the middle part of upper frame 3, coiling ring body 4 and lower frame 5, and coiling ring body 4 outsides are installed with taper type coil 1 wide at the top and narrow at the bottom, and the external diameter of upper frame 3 is greater than the external diameter of lower frame 5; The external diameter of coiling ring body 4 is less than the external diameter of lower frame 5, and the external diameter of the external diameter of upper frame 3 and lower frame 5 is corresponding with the top and the bottom external diameter of taper type coil 1 respectively.Like this, adopt taper design, effectively utilized stator space, increased winding space through coil.
As shown in Figure 1, according to actual needs, the outside of upper frame 3 and lower frame 5 is cambered surface.
