Hoisting type universal rotor critical rotating speed testing device

The invention relates to a hoisting type universal rotor critical rotating speed testing device which comprises a high-speed motor, a coupler, a bearing pedesatl, a flange support and an equipment support. An output shaft of the high-speed motor is connected with the coupler through a flexible connecting disc structure, and the coupler is installed in the bearing pedestal through a high-speed bearing; the bearing pedestal is connected with the flange support through a circumferential vibration damper, and the flange support is fixed on the equipment support. According to the invention, by adopting the flexible connecting disc and the circumferential vibration damper structure, strong vibration generated by the rotor at the critical rotating speed can be overcome during an overspeed experiment, so that the mechanical safety performance of the rotor after passing through the critical rotating speed can be tested. 本发明涉及一种吊装式通用型转子临界转速测试装置，包括高速电机、联轴器、轴承座、法兰支架、设备支架，所述高速电机的输出轴通过柔性连接盘结构连接联轴器，所述联轴器通过高速轴承安装在轴承座内，所述轴承座与
