Detailed ways
1 和套设在线圈 套1外围的线圈外壳2,线圈内套1 低碳钢或其它导磁材料制成,作用是増强磁 As shown in Figure 1-2, the coil components of the electromagnetic clutch include a coil inner sleeve 1 and a coil outer sleeve 2 which is arranged around the coil inner sleeve 1 . It is strong magnetic .
1 之间、以及线圈内套1与漆包线圈3 1 之间并能 所述的漆包线圈31封装的绝缘封装结构4。 A coil 3 is provided between the coil case 2 and the coil inner sleeve 1, and the coil 3 includes an enameled coil 31. A surface of the enameled coil 31 is provided between the coil case 2 and the enameled coil 31 , and the coil inner sleeve 1 is provided. An insulating encapsulation structure 4 that is capable of encapsulating the enameled coil 31 with the enameled coil 31. , 绝缘封装结构4为复合式绝缘封装结构,绝缘封装结构4起着密封和固定的作用。 Specifically , the insulation package structure 4 is a composite insulation package structure, and the insulation package structure 4 plays a role of sealing and fixing.
- 2 和图3所示,该绝缘封装结构 4 包括包覆在漆包线圈3 1 表面的绵层41,在绵层4 1 上设有包括由环氧树脂在内的材料注塑制成 所述的绵层41嵌固的塑封层42。 As shown in Figures 1-2 and 3, the insulating package structure 4 includes a cotton layer 41 covering the surface of the enameled coil 31, and the cotton layer 41 is provided with an injection-molded material including epoxy resin. The plastic sealing layer 42 can be embedded in the cotton layer 41. 41 具有若干阵列分布的编织孔,在塑封层 4 2 上具有若干与所述的编织孔一一对应的嵌固凸起,嵌固凸起设于所述的编织孔中。 The cotton layer 41 has a plurality of braided holes distributed in an array, and the plastic sealing layer 42 has a plurality of embedded protrusions corresponding to the braided holes one by one, and the embedded protrusions are arranged in the braided holes.
1 1, 在线圈外壳2的一端具有套设在外环形定位台阶 1 1 与线圈外壳2连为一体式结构的环形挡板2 1 , 所述的线圈外壳2、环形挡板2 1 和线圈内套 1 之问形成线圈安装环形槽a。 Secondly, as shown in Figures 2 and 4-5, in order to facilitate disassembly, an outer annular positioning step 1 is provided on the outer wall of one end of the coil inner sleeve 1, and one end of the coil housing 2 is sleeved on the outer annular positioning step 1 1 And the ring baffle 21 , which is connected to the coil housing 2 in an integrated structure, forms the coil mounting ring groove a between the coil housing 2, the ring baffle 21, and the coil inner sleeve 1 . The coil 3 is provided in the coil mounting annular groove a. 1 设有外环形定位台阶11的一端内壁设有内环形定位台阶 1 2 An inner annular positioning step 1 2 is provided on an inner wall of one end of the coil inner sleeve 1 provided with an outer annular positioning step 11 .
1 上设有向外凸起的过线部22,所述的过线部22 设有若干过线孔23。 In addition, a ring-shaped baffle 21 is provided with a protruding wire passing portion 22, and the wire passing portion 22 is provided with a plurality of wire passing holes 23. 1 上设有若干向外凸起的定位柱24,线圈3上的导线穿过过线部22的过线孔23。 The annular baffle plate 21 is provided with a plurality of positioning posts 24 protruding outward, and the wires on the coil 3 pass through the wire passing holes 23 of the wire passing portion 22.
1 之问填充并将漆包线圈31封装,不仅能提高结构强度,而且能形成一个部件以便于拆装,降低了拆装难度和提高了生产效率。 Filling the coil case 2 with the enameled coil 31, the coil inner sleeve 1 and the enameled coil 31 by epoxy resin and encapsulating the enameled coil 31 not only can improve the structural strength, but also form a component for easy disassembly It reduces the difficulty of disassembly and improves the production efficiency.
