Description
本发明属于机械技术领域，涉及一种电磁失电制动器的减振传动联接装置。
电磁失电制动器由铁芯、弹簧、衔铁、摩擦片、制动盘、传动联接装置等部件组成，主要应用于各类电机的制动。电磁失电制动器的铁芯在加电后绕组产生磁场，将衔铁吸回，此时衔铁压缩固定在铁芯内的弹簧，与制动盘通过联接装置连接的电机转轴处于可自由转动；当铁芯失电后，铁芯的磁场消失进而失去对衔铁的吸力，弹簧将衔铁弹出，衔铁与制动盘被相互压紧，通过摩擦片在制动盘上产生制动转矩来限制制动盘的转动，而制动盘与转子之间是通过传动联接装置连接，因此也就限制了电机转子的转动。
电磁失电制动器的工作原理决定了制动盘工作时在轴向存在位移自由度，这就要求制动盘与转子之间的传动联接存在一定间隙，间隙的存在就极有可能导致电机运行时在传动联接部位产生噪音和振动，影响了使用者的用户体验。
本发明的目的是针对现有的技术存在上述问题，提供了一种可有效降低制动盘与转子之间的噪音的电磁失电制动器的减振传动联接装置。
本发明的目的可通过下列技术方案来实现：
一种电磁失电制动器的减振传动联接装置，电磁失电制动器包括制动盘，所述制动盘的中心开设有连接孔，所述连接孔的孔壁凹陷形成内花键槽，所述制动盘上设置有弹性片，所述弹性片包括与制动盘端面接触的弹性片基片，弹性片基片对应于制动盘中心孔的花键槽处设有向花键槽内翻折并形成在花键槽两侧壁旁的挡片，所述挡片处于自由状态时与花键槽的侧壁之间形成有一倾斜夹角。
挡片处于自由状态时与花键槽的侧壁之间形成有一倾斜夹角从而使挡片与键槽的侧壁之间形成间隙，转子能嵌入制动盘的连接孔内，且转子上设有花键，转子上的花键能嵌入花键槽内，当制动盘与电机转子连接时，电机转子的花键压缩挡片，挡片在制动盘与电机转子的花键之间形成弹性缓冲，从而可有效消除电机运转过程中电机转子花键与制动盘之间因撞击而发出的噪音，降低了电机的运转噪音。弹性片基片能对挡片实现良好的定位且稳定性较好，在长时间使用后，还是能起到较好的缓冲作用，并且能降低制动盘与转子之间的噪音，提高了使用者的用户体验。
作为优选，所述挡片端部弯折形成限位板，所述限位板与制动盘相贴合，所述挡片与限位板之间形成限位凹口，所述制动盘能部分嵌入限位凹口内。该结构的设置，使得弹性片能更好的设置在制动盘上，提高了弹性片与制动盘连接的稳定性，使得在电机运行时，挡片能稳定的吸收噪音和冲击力。
作为优选，所述挡片与限位板之间圆滑过渡。挡片与限位板之间圆滑过渡能使挡片获得更好的弹性，从而使挡片能对制动盘和转子之间起到更好的缓冲减噪作用。
作为优选，弹性片基片对应于制动盘中心孔的每一个花键槽内均设置有挡片。在每个花键槽内均设置挡片可进一步加强挡片对制动盘和转子之间的缓冲减噪效果。
作为优选，所述倾斜夹角为
1-10
度。将倾斜夹角的角度控制
1-10
度之间，既可保证挡片对于制动盘和电机转子之间的弹性缓冲，又可保证制动盘和电机转子的之间的装配方便。
作为优选，所述弹性片基片上设有安装部，所述挡片设置在安装部的两端，所述安装部上设有与挡片连接的连接部，所述连接部与安装部之间具有让位凹口。该结构的设置，使得挡片能更好的设置在内花键槽内，对于尺寸相似的制动盘，弹性片都可以进行安装，进一步的提高了弹性片的通用性能。
作为优选，所述弹性片采用金属弹性材料制成。采用金属弹性材料使得弹性片能在减少噪音和缓冲的前提下，极大程度上提高弹性片的耐用程度，并且使得弹性片的结构和强度能更加的稳定。
与现有技术相比，本电磁失电制动器的减振传动联接装置具有以下优点：
、挡片在制动盘与电机转子的花键之间形成弹性缓冲，从而可有效消除电机运转过程中电机转子花键与制动盘之间因撞击而发出的噪音，降低了电机的运转噪音。弹性片基片能对挡片实现良好的定位且稳定性较好，在长时间使用后，还是能起到较好的缓冲作用，并且能降低制动盘与转子之间的噪音，提高了使用者的用户体验。
、限位板的作用，使得弹性片能更好的设置在制动盘上，提高了弹性片与制动盘连接的稳定性，使得在电机运行时，挡片能稳定的吸收噪音和冲击力。
