Coil parts of electromagnetic clutch (1)

Release time: October 23, 2016

本实用新型属于电磁离合器技术领域,尤其是涉及一种电磁离合器的线圈部件。 TECHNICAL FIELD: The utility model belongs to the technical field of electromagnetic clutches, and particularly relates to a coil component of an electromagnetic clutch.
Background technique
The electromagnetic clutch controls the engagement and disengagement of the clutch by turning on and off electricity. 线圈制作完毕,然后进行 装。 At present, when the existing electromagnetic clutch is assembled, the coil is first manufactured and then assembled . This method can meet the production requirements to a certain extent, but this method still has at least the following defects: irrational design, cumbersome installation process and increased production costs; secondly, the split-type installation design has low structural strength and poor sealing. In order to solve the above-mentioned technical problems, people have conducted long-term explorations and proposed various solutions .
轴向内缩设置,缩进距离为衔铁的轴向宽度,衔铁焊接在磁轭体 , 磁率通体内设有永磁线圈,永磁线圈通过联轴器与磁轭体连接,永磁线圈具有弯折段,弯折段与联轴器在径向截面 的边缘曲率相同,弯折段的两端向永磁线圈中心内侧延伸有弯折部,弯折部朝向永磁线圈中心端面与磁轭体端面相对,永磁线圈内设有内齿套,内齿套内壁上开有数条通槽,通槽宽度为一至两毫米。 An electromagnetic clutch includes a yoke body. An armature is provided on the yoke body. The yoke body is axially retracted at the corresponding armature. The indentation distance is the axial width of the armature. The armature is welded to the yoke body . There is a permanent magnet coil in the pass body.The permanent magnet coil is connected to the yoke body through a coupling.The permanent magnet coil has a bending section. The bending section has the same curvature as the edge of the coupling in the radial section . Both ends extend to the inner side of the center of the permanent magnet coil, and the bent portion faces the center end surface of the permanent magnet coil and opposes the end surface of the yoke body. The inner coil of the permanent magnet coil is provided with a plurality of through grooves on the inner wall of the inner coil. The through slot width is one to two millimeters. The electromagnetic clutch shortens the axial width of the entire yoke body, saves raw materials, effectively ensures the stability of installation, can extend the service life of the electromagnetic clutch to a certain extent, and has good safety performance and flexible installation methods.
Although the above solution has the above-mentioned advantages, it still has the following technical problems: it still fails to improve the above technical problems and has poor practicability.
Utility model content
The purpose of the present utility model is to provide a coil component of an electromagnetic clutch with a more reasonable design, improved structural strength, and good tightness.
了下列技术方案:本电磁离合器的线圈部件包括线圈 套和套设在线圈内套外围的线圈外壳,在线圈外壳和线圈内套之间设有线圈,该线圈包括漆包线圈,在漆包线圈的表面设有填充在线圈外壳和漆包线圈之间、以及线圈内套与漆包线圈之间并能将所述的漆包线圈封装的绝缘封装结构。 In order to achieve the above purpose, the present utility model adopts the following technical scheme: The coil component of the electromagnetic clutch includes a coil inner sleeve and a coil shell sleeved around the coil inner sleeve, and a coil is provided between the coil shell and the coil inner sleeve. The coil includes an enameled coil, and an insulation package structure is provided on the surface of the enameled coil, which is filled between the coil shell and the enameled coil, and between the coil inner sleeve and the enameled coil, and can encapsulate the enameled coil. 线圈外壳和漆包线圈之间、以及线圈内套与漆包线圈之间填充并 漆包线圈封装,密封 好且结构强度高,其次,还使于拆装,提高了生产效率。 Due to the insulation package structure, the new type can fill and seal the enameled coil between the coil shell and the enameled coil, and between the coil inner sleeve and the enameled coil , which has good sealing performance and high structural strength. Improved production efficiency.
In the coil component of the electromagnetic clutch, the insulation package structure is a composite insulation package structure. 所述的绵层嵌固的塑封层。 In the coil part of the electromagnetic coupler, the insulating package structure includes a cotton layer covering the surface of the enameled coil, and the cotton layer is provided with an injection molding material including epoxy resin, and the described Cotton embedded plastic layer. 绝缘和封装时能使环氧树脂均匀分胶的作 The cotton layer plays a role in making epoxy resin uniformly distributed during insulation and encapsulation . 板和线圈内套之间形成线圈安装环形槽。 The outer wall of one end of the inner sleeve of the electric coil is provided with an outer ring-shaped positioning step, and at one end of the coil housing, there is an annular baffle sleeved on the outer ring-shaped positioning step and connected to the coil casing as an integrated structure. A coil mounting annular groove is formed between the coil inner sleeves. One end of the coil is provided with an outer annular positioning step, and an inner annular positioning step is provided on the inner wall. The inner annular positioning step is used to install a bearing.
有的技术相比,本电磁离合器的线圈部件的优点在于:1、设计更合理,由于设置了绝缘封装结构能够将线圈外壳和漆包线圈之间,以及线圈内套与漆包线圈之间填充并将漆包线圈封装,密封性好 结构强度高,其次,还便于拆装,提高了生产效率。 Compared with the prior art, the coil components of the electromagnetic clutch have the advantages of: 1. The design is more reasonable. Because the insulation package structure is provided, the coil shell and the enamel coil can be filled, and the coil inner sleeve and the enamel coil can be filled. The enameled coil is packaged with good sealing and high structural strength. Secondly, it is easy to disassemble and improve production efficiency. 寿命长 2. Simple structure, easy to manufacture and long service life .
