The invention belongs to the technical field of gas turbines, and particularly relates to a supporting device for a modular rotor experiment table, which comprises a rotor supporting seat, a supporting threaded sleeve, a guide pipe, a supporting screw rod, a planetary gear set, a main shaft, a bevel gear wheel, a bevel pinion, a shell, a base, a coupler, a motor, a motor seat upper cover and a motor base. The supporting threaded sleeve does reciprocating rectilinear motion in the guide pipe; a guide pipe for supporting the threaded sleeve is positioned with the shell through a positioning pin; the supporting screw rod is in threaded connection with a planet carrier of the planetary gear set; an outer gear ring in the planetary gear set is fixed in the shell through a positioning groove; the bevel gear wheel and a sun gear of the planetary gear set share the same main shaft; an output shaft of the motor is connected with the bevel pinion shaft through a coupler; the motor is fixed on the base through the motor upper cover and the motor base by means of bolts. The task switching efficiency of the modularized rotor experiment table can be remarkably improved through combined use; the supporting device is simple, portable and convenient to operate.
Description
technical field [0001] The invention belongs to the technical field of gas turbines, and in particular relates to a support device for a modular rotor test bench. Background technique [0002] Rotating machinery is a mechanical device widely used in industry, and it is of great significance to carry out corresponding experimental research to improve the theory of rotor dynamics. In order to quickly verify the accuracy of different theoretical results, a modular rotor test bench came into being. The modular rotor test bench can realize multi-task experimental requirements flexibly, efficiently and at low cost. But when it is necessary to switch tasks, especially when studying the influence laws of bearings with different structures, the entire test bench will have to be disassembled. In order to reduce the time-consuming disassembly and assembly and the damage to the rotor, a simple, portable, easy-to-operate and wide-applicable rotor-specific support device was designed, w...
