Machine loader

Abstract

The invention particularly relates to a machine loader, which is used for solving the problems that the prior loaders can not freely load or unload at any time within the megawatt range after the motor starts and ensure stable load. The machine loader comprises a speed reducer, wherein the speed reducer is provided with a first output shaft and a second output shaft which are respectively connected with the shaft and gear of a loading gearbox; the input shaft of the speed reducer is provided with a motor and connected with a motor shaft; and the motor is provided with a power supply system and a power failure brake. The machine loader of the invention has reasonable and reliable structural design, can load with kilowatts of power without machines, and is not limited to the stroke in the loading process. All the clearances generated in the connecting links in the closed system, especially the tooth side clearances at all levels when the tested speed reducer is in multistage transmission can be eliminated, thereby ensuring smooth loading in one installation. The machine loader of the invention has the advantages of sensitive and stable loading, and the like, and is especially suitable for high-power mechanical closed test beds.

Description

technical field [0001] The invention relates to a loader, in particular to a mechanical loader. Background technique [0002] The megawatt-level mechanical power fully enclosed test bench is suitable for the mechanical processing industry to test the gear strength and gearbox life of megawatt-level gearboxes, gearboxes, and reducers. The energy-saving effect is very prominent. It can be used for type tests, factory tests, Strength test and fatigue life test. However, the core of the megawatt-level mechanical power fully enclosed test bench is the mechanical loader. At present, the megawatt-level mechanical power fully enclosed test bench includes the tested reducer 4 and the test reducer 6 connected by the coupling 5. The input shaft of the tested reducer 4 is connected with the input sensor 3 and the loading gearbox 2. The gear box 2 is connected with the gear box 9 through the transmission shaft 8, the gear box 9 is connected with the output sensor 7, and the output sens...
