Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Fig. 2 Fig. 3, a kind of armature, comprises machine shaft, armature core and rear trim ring 2, on the outer ring face of rear trim ring 2, is provided with coil 1, is to be provided with micarex 12 between coil 1 and rear trim ring 2, the main insulating effect that rises of micarex 12; The trim ring stop portion of rear trim ring 2 tail ends is provided with and supports protection assembly; be outside equipped with flange belts 4 at coil 1; be wrapped with without latitude band 5 at flange belts 4; also be provided with polytetrafluoroethylene film 6 at flange belts 4 with between without latitude band 5, polytetrafluoroethylene film 6 and flange belts 4 through without 5 colligations of latitude band on coil 1 surface.
Support protection assembly and comprise the support 3 that is arranged on rear trim ring 2 tail end stop portions; coil 1 is arranged in the cavity being formed by armature core, rear trim ring 2 and support 3; on support 3, be socketed with insulated ring 11; insulated ring 11 contacts with outer ring face and the end face of support 3; be outside equipped with and headgear 8 at insulated ring 11, also between headgear 8 and phase insulated ring 11, be provided with rubber blanket 10.Rubber blanket 10 is enclosed within on the outer face of insulated ring 11, is mainly cushioning effect, and rubber blanket 10 can directly be made moulding on insulated ring 11.
By and headgear 8 and support 3 between the rubber blanket 10 that arranges, alleviate due to the coil 1 lengthwise dimension axial force producing that increases sharply, improve and finish member stress situation, avoid support 3 to ftracture, the safety of guarantee structural member.
