Description

Technical Field

[0001] This utility model relates to the field of D-type bar technology, specifically a D-type bar fixing device for a generator exciter. Background Technology

[0002] With the development of society, generator exciters are used in more and more applications. D-type rods are an essential part of generator exciters. The heating of D-type rods will cause the relative displacement between the surface insulation layer and the shaft. Since the shaft is made of metal and the surface of the rod is made of resin insulation, wear of the insulation layer is inevitable.

[0003] The existing structure and connection method of D-type rods do not meet the operating conditions of frequent start-stop in peak-shaving power plants, affecting the working efficiency and operational stability of D-type rods. Therefore, we propose a generator exciter D-type rod fixing device to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of this utility model is to provide a D-type rod fixing device for a generator exciter to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A generator exciter D-type bar fixing device includes a bar body and a rotating shaft disposed on the outside of the bar body, and also includes an anti-wear component. The anti-wear component is used to prevent wear between the bar body and the rotating shaft. The anti-wear component is disposed between the bar body and the rotating shaft. The anti-wear component includes an insulating plate. Two sets of insulating plates are provided. The two sets of insulating plates are respectively disposed on the outer wall of the bar body and the inner wall of the rotating shaft. A set of protective mechanisms is provided on each side wall of the two sets of insulating plates. One set of protective mechanisms is disposed between the insulating plate and the bar body, and the other set of protective mechanisms is disposed between the insulating plate and the rotating shaft.

[0007] As a further embodiment of this utility model: the protective mechanism includes a wear-resistant layer, a protective layer and an anti-slip layer, wherein the protective layer is disposed on the wear-resistant layer and the anti-slip layer is disposed on the protective layer.

[0008] As a further embodiment of this invention: the anti-slip layer comprises multiple anti-slip particles spaced apart.

[0009] As a further embodiment of this invention, the protective layer is composed of a sponge surface.

[0010] As a further embodiment of this invention, the wear-resistant layer is a wear-resistant and antibacterial component.

[0011] As a further embodiment of this utility model: an epoxy resin layer is provided on one side of the outer wall of each of the two sets of protective mechanisms, and an epoxy resin adhesive layer is provided between the protective mechanism and the epoxy resin layer.

[0012] As a further improvement of this utility model, the overall thickness of the two sets of anti-wear components is 0.5mm.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This generator exciter D-type bar fixing device, by setting up anti-wear components, ensures that the insulating plate is firmly bonded with 0.5mm thick epoxy resin and epoxy resin adhesive, improving the stability of the connection and fixing between the bar body and the shaft. At the same time, through the setting of the protective mechanism, the insulating plate has wear-resistant, protective and anti-slip functions, which further enhances the anti-wear effect, reduces the wear between the bar body and the shaft, improves the utilization efficiency of the bar body and the shaft, and extends the service life of the bar body and the shaft.

[0019] In one embodiment, such as Figures 1-3As shown, a generator exciter D-type rod fixing device includes a rod body 1 and a rotating shaft 2 disposed on the outside of the rod body 1. It also includes an anti-wear component to prevent wear between the rod body 1 and the rotating shaft 2. The anti-wear component is disposed between the rod body 1 and the rotating shaft 2. The anti-wear component includes an insulating plate 3, with two sets of insulating plates 3 respectively disposed on the outer wall of the rod body 1 and the inner wall of the rotating shaft 2. A protective mechanism 4 is disposed on each side wall of both sets of insulating plates 3, with one protective mechanism 4 positioned between the insulating plate 3 and the rod body 1. The protective mechanism 4 is set between the insulating plate 3 and the rotating shaft 2. After the rod body 1 is installed on the rotating shaft 2, two sets of insulating plates 3 are installed between the rod body 1 and the rotating shaft 2. A 0.5mm thick epoxy resin insulating plate 3 is inserted between the insulation layer of the rod body 1 and the inner diameter of the rotating shaft 2 (the insertion depth depends on the wear of the insulation layer) and then glued firmly with epoxy resin. This improves the stability of the connection and fixation between the rod body 1 and the rotating shaft 2, allowing the rod body 1 and the rotating shaft 2 to run smoothly during operation. This further improves the stability of the generator exciter's operation and is quite practical.

[0020] like Figures 2-3 As shown, the protective mechanism 4 includes a wear-resistant layer 5, a protective layer 6, and an anti-slip layer 7. The protective layer 6 is disposed on the wear-resistant layer 5, and the anti-slip layer 7 is disposed on the protective layer 6. The anti-slip layer 7 includes multiple anti-slip particles spaced apart. The protective layer 6 is composed of a sponge surface. The wear-resistant layer 5 is a wear-resistant and antibacterial component. An epoxy resin layer is disposed on one outer wall of each of the two sets of protective mechanisms 4, and an epoxy resin adhesive layer is disposed between the protective mechanism 4 and the epoxy resin layer. The overall thickness of the two sets of anti-wear components is 0.5mm. Through the setting of the protective mechanism 4, the insulating plate 3 has the functions of wear resistance, protection, and anti-slip, which enables the insulating plate 3 to further play the role of anti-wear, reduce the wear degree between the bar body 1 and the shaft 2, improve the utilization efficiency of the bar body 1 and the shaft 2, and extend the service life of the bar body 1 and the shaft 2, thereby reducing resource waste.

[0021] The above embodiment discloses a D-type rod fixing device for a generator exciter. After the rod body 1 is installed on the rotating shaft 2, two sets of insulating plates 3 are installed between the rod body 1 and the rotating shaft 2. A 0.5mm thick epoxy resin insulating plate 3 is inserted between the insulation layer of the rod body 1 and the inner diameter of the rotating shaft 2 (the insertion depth depends on the wear condition of the insulation layer) and then firmly bonded with epoxy resin adhesive. This improves the stability of the connection and fixing between the rod body 1 and the rotating shaft 2. At the same time, through the setting of the protective mechanism 4, the insulating plate 3 has the functions of wear resistance, protection, and anti-slip, which enables the insulating plate 3 to further play the role of anti-wear, reduce the wear degree between the rod body 1 and the rotating shaft 2, and improve the utilization efficiency of the rod body 1 and the rotating shaft 2.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
