[0023] like Figures 1 to 2 As shown, the input power assembly also includes: a locking device 8, mounted on the first rotating shaft 6 and located on the side of the first connecting flange bracket 4 away from the load output assembly, for simulating emergency conditions and adjusting the rotation speed of the first rotating shaft 6; a first grating 9, mounted on the first rotating shaft 6 and located between the locking device 8 and the first servo motor 7, for detecting the rotation speed of the reducer input end; a first torque sensor 10, mounted on the first rotating shaft 6 and located between the first servo motor 7 and the first fixed bracket 5, for detecting the torque at the reducer input end.
[0024] Example 2: Figures 1 to 2 As shown, the load output assembly includes: a second fixed plate 11, mounted on the workbench 1; a second connecting flange bracket 12, mounted on the side of the second fixed plate 11 close to the load output assembly, for fixing the output end of the reducer; a second fixing frame 13, mounted on the side of the second fixed plate 11 away from the load output assembly; a second rotating shaft 14, mounted between the second connecting flange bracket 12 and the second fixing frame 13, and rotatably connected to the second connecting flange bracket 12 and the second fixing frame 13; a second servo motor 15, mounted on the second fixing frame 13, for driving the second rotating shaft 14 to rotate, so that the rotating shaft drives the output end of the reducer to rotate.

[0026] like Figure 1 As shown, it also includes: multiple sets of universal wheels 18, evenly installed at the bottom of the workbench 1, for facilitating the movement of the workbench 1.
[0027] like Figure 1 As shown, it also includes: a protective cover 19 installed on the first fixing plate 3, used to protect the input power component.
[0028] In the above scheme, the operations of the grating, the locking device 8 and the torque sensor are all existing technologies and are controlled by the existing control system. They are well known in the art and are understood by practitioners in this industry, so they will not be repeated here.
[0029] The technical solution provided by the present invention first checks whether the various components of the test bench are firmly connected, calibrates and zeroes each sensor, starts the first servo motor 7 and the second servo motor 15, performs a short no-load test run, observes whether the motor runs smoothly and whether there is any abnormal noise or vibration, places the reducer to be tested at the position of the fixing component 2 on the workbench 1, adjusts the position of the input power component and the load output component, aligns the first connecting flange bracket 4 with the input end of the reducer, and aligns the second connecting flange bracket 12 with the output end of the reducer, and firmly fixes the reducer with the fixing component 2 to ensure that the reducer will not be displaced or loosened during subsequent testing; then starts the test, starts the first servo motor 7, and drives the first rotating shaft 6 to rotate according to the preset speed and torque parameters. The first rotating shaft 6 transmits power to the reducer's input via the first connecting flange bracket 4, driving the reducer into operation. During the rotation of the first rotating shaft 6, the braking device 8 is in standby mode and can be activated at any time to simulate emergency conditions as required by the test. The first optical grating 9 detects the speed of the reducer's input in real time and transmits the data to a display terminal. The first torque sensor 10 simultaneously detects and records torque data at the input. The second servo motor 15 drives the second rotating shaft 14 according to the set load pattern, simulating the application of a corresponding load to the reducer's output. The second optical grating 16 detects the speed of the reducer's output, and the second torque sensor 17 detects the torque at the output. By comparing the speed and torque data at the input and output ends, performance parameters such as the reducer's transmission efficiency and torque variation can be calculated. During the test, the speed of the first servo motor 7 and the load of the second servo motor 15 can be adjusted as needed to obtain performance data for the reducer under different operating conditions. Finally, the data detected by each sensor is transmitted in real time to the data acquisition system for recording and storage. The recorded data includes input speed, input torque, output speed, output torque at different time points, as well as relevant data during simulated emergency conditions. The collected data is analyzed and processed to calculate various performance indicators of the reducer, such as transmission ratio, efficiency curve, and torque fluctuation. By comparing with standard performance indicators or previous test data, the performance of the reducer is evaluated and whether it meets quality requirements is determined.
[0030] This invention encompasses any alternatives, modifications, equivalents, and solutions that do not depart from the spirit and scope of this invention. While specific details are described in detail in the preferred embodiments of this invention to provide a thorough understanding, those skilled in the art will be able to fully understand this invention without these details. Furthermore, to avoid unnecessary confusion regarding the essence of this invention, well-known methods, processes, procedures, components, and circuits have not been described in detail.
[0031] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
