Diaphragm coupling

The invention provides a diaphragm coupling which comprises a connecting pipe connected outside an axle in a sleeving mode and a transmission mechanism, the transmission mechanism comprises a first flange plate arranged at the output end of the connecting pipe and a first diaphragm assembly arranged on the first flange plate, a fixing base is arranged on the first flange plate, and a second flange plate is arranged on the fixing base. The first diaphragm assembly comprises a metal diaphragm installed on the first flange plate through a fixing base, and the metal diaphragm is fixedly connected with a wheel through a connecting shaft. According to the diaphragm coupling, the potential risk that warping exists between the layers of the metal diaphragms can be effectively reduced, and it is further ensured that the diaphragm coupling can still keep stable torque transmission output under the high-frequency vibration working condition. 本发明提供了一种膜片联轴器，包括套接在车轴外的连接管，以及传动机构，其包括设置在所述连接管的输出端的第一法兰盘，以及设置在所述第一法兰盘上的第一膜片组件，其中
