Embodiment Construction

[0024] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0025] Such as figure 1 As shown, it is an iron core packaging method reinforced with composite materials, including dovetail key 1, iron core 2, composite material 3, and epoxy resin 4. A long stator packaging method reinforced with composite material 3 is:

[0026] The first step: before the iron core 2 is encapsulated by the epoxy resin 4, the iron core 2 is cleaned;

[0027] The second step: laying the composite material 3 on the surface of the iron core 2, and fixing the composite material 3 and the iron core 2;

[0028] The third step: pouring the iron core 2 with epoxy resin 4; the epoxy resin 4 is poured on the iron core 2 through the epoxy resin casting process; and the epoxy resin casting process can usually choose vacuum casting ...

Abstract

The invention discloses an iron core packaging method adopting a composite material for enhancement; the method comprises an iron core, a composite material and epoxy resin, and the packaging method comprises the following steps that a step 1, the iron core is cleaned before the iron core is encapsulated by the epoxy resin; a step 2, the composite material is laid on the surface of the iron core,and the composite material is fixed with the iron core; and a step 3, the epoxy resin is poured on the iron core by adopting an epoxy resin pouring process. The composite material coating is added onthe surface of the iron core, so that the composite material layer is added inside the epoxy resin, and therefore the strength and the cracking resistance of the epoxy packaging layer can be remarkably improved and, meanwhile, the environmental protection performance is improved, and the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to a packaging method, specifically, an iron core packaging method reinforced with composite materials, and belongs to the technical field of long stator packaging. Background technique [0002] In the maglev train, the long stator linear motor is a core component, which is mainly composed of iron core, dovetail key and epoxy package. Long stator linear motors are installed on rails and are products for outdoor applications. For epoxy packaging, it is characterized by large epoxy packaging area, thin wall thickness, and uneven thickness of each part. The thickness of most of the epoxy layer is 1.5-2mm, which requires good mechanical strength, especially crack resistance. [0003] The existing technology only adjusts the formula of epoxy resin (such as resin, filler, curing agent, toughening agent), and optimizes the epoxy packaging process of the iron core, so that the epoxy resin layer is dense, smooth and not easy to crack. H...
