Flexible coupling

The invention relates to the technical field of powder making equipment, in particular to a flexible coupling. The flexible coupling comprises a conductive elastic part, multiple flexible conductive parts and a connecting part, the conductive elastic part comprises a cylinder with a hole in the center, multiple through holes formed in the axial direction are formed in the periphery of the cylinder, the flexible conductive parts penetrate through the through holes, and the connecting part fixedly connects the conductive elastic part with the flexible conductive parts through one or multiple fixed parts. The current transmission capacity of the coupling can be improved, and the rotating speed of an electrode bar can be improved. 本发明涉及制粉设备技术领域，尤其涉及一种柔性联轴器。该柔性联轴器包括：导电弹性构件，所述导电弹性构件包括一中心开孔的筒体，所述筒体的周边上具有多个沿轴向开设的通孔；多个柔性导电件，各所述柔性导电件分别贯穿于所述通孔中；连接件，所述连接件通过一个或多个固定件将所述导电弹性构件和多个所述柔性导电件固定连接。本发明增加了联轴器的电流传输能力，提高了电极棒料的转速。
