Abstract
The utility model discloses a synchronous generator brush holding cover. The cover comprises a U-shaped sheet, a thin steel sheet, and an arc sheet and a round tube with the same radian. The arc sheet and the round tube are transversely arranged in parallel, and a cambered surface is formed between the two. The U-shaped sheet is vertically arranged. Two ends of the arc sheet are connected to two ends of the U-shaped sheet respectively, and two ends of the round tube are connected to two corners of the U-shaped sheet respectively. The thin steel sheet is laid on the cambered surface. The cover has the following advantages: 1. no mold is needed, molding costs are reduced, and a framework can be changed freely according to usage needs; 2. as the framework combines framework functions and supporting functions after being welded, the cover has high strength and rigidity; 3. compared to one-step molding techniques in the prior art, the thin steel sheet ultimately used is lighter than materials currently used, so that the final weight is reduced; 4. the whole cover is simple and quick in manufacturing technique; and 5. with the round tube as an edge, the cover has not only an inverted arc corner function but a beautiful look as well.
Description
Technical field
The utility model relates to a kind of synchronous generator brush carrier cover, belongs to synchronous generator brush carrier technical field.
Background technology
The brush carrier cover of synchronous generator generally adopt steel plate forming or glass fibre molded.Adopt the intensity of steel plate forming good, but rigidity is inadequate, easily distortion; Adopt glass fibre molded there is certain insulating properties, good rigidity, but insufficient strength, easily cracking.Two kinds of molding modes all need to develop molding die, by mould one-shot forming, because the size of brush carrier cover need to change to some extent, therefore, in use, need to develop different moulds, and it possesses following weak point:
1, molding die complexity, cost are high, are not suitable for often changing and the production of small lot;
2, steel plate need to meet certain thickness, otherwise easily fracture in forming process;
3, the manufacturing process complexity of glass fibre brush carrier cover, intensity is low, easy to crack;
4, steel plate forming structure mold cost is high, weld yielding, poor rigidity, and adopt the outward appearance of Plate Welding to be difficult for there is fillet, fail safe is poor, weight is large.
Utility model content
The purpose of this utility model is: a kind of synchronous generator brush carrier cover is provided, thereby can effectively solves above-mentioned problems of the prior art.
The purpose of this utility model is to realize by following technical proposals: a kind of synchronous generator brush carrier cover, comprise arc-like sheet and the pipe of U-shaped sheet, sheet metal, identical radian measure, described arc-like sheet and pipe laterally be arranged in parallel, form a cambered surface between the two, U-shaped sheet vertically arranges, the two ends of described arc-like sheet connect respectively the two ends of U-shaped sheet, and the two ends of pipe are connected with two corners of U-shaped sheet respectively, and described sheet metal is laid in cambered surface.
As optimal way, also comprise the thin slice of semicircular arc, described thin slice is located between pipe and U-shaped sheet.
As further preferably, at the arc middle part of arc-like sheet and pipe, be vertically connected a circular support hole, the reserved circular hole corresponding with this circular support hole on sheet metal, and a circular steel cylinder is set as steam vent.
As further preferred, described steel-sheet edge is welded and fixed with arc-like sheet and pipe respectively.
As optimal way, described arc-like sheet is provided with the installing hole of being convenient to external flanges installation.
As optimal way, described U-shaped sheet is provided with bolt mounting holes.
Compared with prior art, the beneficial effects of the utility model: the utility model synchronous generator brush carrier cover simple in structure, be easy to install, possess following advantage:
1, do not need mould, reduce molding cost, can need random change framework according to using, thereby adapt to different need of productions;
2,, owing to having the effect of frame structure and support function after frame welding concurrently, therefore, this brush carrier cover has higher strength and stiffness;
3, compare existing one-time formed technique, the final sheet metal using, than existing lighter with material, makes final weight saving;
4, the manufacture craft of whole brush carrier cover is simple, quick;
5, pipe serves as edge, not only possesses the function at inverted arc angle, and good looking appearance.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model synchronous generator brush carrier cover;
Fig. 2 is the structural representation of Fig. 1 middle frame.
In figure: 1-arc-like sheet, 2-U shape sheet, 3-pipe, 4-circular support hole, 5-installing hole, 6-installing hole, 7-sheet metal, 8-steam vent, 9-thin slice.
Embodiment
Below in conjunction with specific embodiment, the utility model is further described.
Disclosed all features in this specification, or the step in disclosed all methods or process, except the speciality and/or step of mutual repulsion, all can combine by any way, unless narration especially, all can be replaced by other equivalences or the alternative features with similar object,, unless narration especially, an embodiment in a series of equivalences of each feature or similar characteristics.
As shown in Figure 1 and Figure 2, the utility model synchronous generator brush carrier cover comprises the thin slice 9 of U-shaped sheet 2, sheet metal 7, semicircular arc, arc-like sheet 1 and the pipe 3 of identical radian measure, described arc-like sheet 1 and pipe 3 laterally be arranged in parallel, form a cambered surface between the two, U-shaped sheet 2 vertically arranges, the horizontal edge of U-shaped sheet is corresponding with the chord length of arc-like sheet 1 or pipe 3, the two ends of described arc-like sheet 1 connect respectively the two ends of U-shaped sheet 2, the two ends of pipe 3 are connected with two corners of U-shaped sheet 2 respectively, and described U-shaped sheet 2, arc-like sheet 1 and pipe 3 form a semicircular space framework.Described sheet metal 7 is laid in cambered surface; Specifically, the edge of described sheet metal 7 is welded and fixed with arc-like sheet 1 and pipe 3 respectively.Described thin slice 9 is located between pipe 3 and U-shaped sheet 2, and the edge of described thin slice 9 is welded and fixed with U-shaped sheet 2 and pipe 3 respectively.Described thin slice 9 and stalloy 7 cover two faces of semicircle space framework, thereby form the profile of brush carrier cover.Arc middle part at arc-like sheet 1 and pipe 3 is vertically connected a circular support hole 4, the reserved circular hole corresponding with this circular support hole 4 on sheet metal 7, and a circular steel cylinder is set as steam vent 8.In addition, for the ease of the installation of this brush carrier cover, on described arc-like sheet 1, be provided with the installing hole 6 of being convenient to external flanges installation, on described U-shaped sheet 2, be provided with bolt mounting holes 5; By installing hole 6, this brush carrier cover is arranged on the parts of other synchronous generators.
Because the utility model brush carrier cover is the frame structure that adopts U-shaped sheet 2, arc-like sheet 1 and pipe 3 to be welded, therefore, do not need to pass through mould molding as existing brush carrier cover, therefore, can, according to regulating arc-like sheet 1 and the radian of pipe 3 and the size of U-shaped sheet to adjust the size of framework, realize the adjusting to brush carrier cover size.Because stalloy is welded in cambered surface, therefore, the size of stalloy is no longer subject to the impact of mould pressing process, can adopt very thin steel disc to make, and moulding process is simple, reduces manufacturing cost.
